Afrotropical Polypedilum subgenus Tripodura, with a review of the subgenus (Diptera: Chironomidae)

Vårdal, H., Bjørlo, A. & Sæther, O. A. (2002). Afrotropical Polypedilum subgenus Tripodura, with a review of the subgenus (Diptera: Chironomidae). —Zoologica Scripta, 31, 331–402. A subgeneric diagnosis for all stages of the subgenus Tripodura Townes, 1 945 of the genus Polypedilum Kieffer, 1 912 is given. Nine new Afrotropical species of Tripodura are described: P.(T.)chelum Vårdal sp. n., P.(T.)amplificatus Bjørlo sp. n., P.(T.)patulum Bjørlo sp. n., P.(T.)spinalveum Vårdal sp. n., P.(T.)ewei Bjørlo sp. n., P.(T.)ogoouense Bjørlo sp. n., P.(T.)akani Bjørlo sp. n., P.(T.)dagombae Bjørlo sp. n., and P.(T.)amputatum Bjørlo sp. n.; all as male imagines only. P.(T.)alboguttatum Kieffer, P.(T.)albosignatum Kieffer, P.(T.)tropicum Kieffer, P.(T.)pruina Freeman, P.(T.)quinqueguttatum Kieffer, P.(T.) aegyptium Kieffer, P.(T.) tridens Freeman, P.(T.)allansoni Freeman, P.(T.)longicrus Kieffer, P.(T.)annulatipes Kieffer and P.(T.)abyssiniae Kieffer are re‐described as male and female imagines, while P.(T.)majiis Lehmann, P.(T.)subovatum Freeman, P.(T.)griseoguttatum Kieffer, P.(T.)aferum Lehmann and P.(T.)kijabense Freeman are re‐described as male imagines only. Keys to the male and the known female imagines of the 30 Afrotropical species in the subgenus are presented. A phylogenetic analysis based on all available information on Tripodura from all over the world (135 species) is presented and discussed. The monophyly of the subgenus Tripodura is confirmed. The subgenus can be divided into 20 groups with the acifer group forming the sister group of two larger assemblages of groups in the order acifer (titicacae (ginzansecundum ((aferum (ewei (malickianum (floridense (halterale, pullum)))))) (subovatum (labeculosum ((parascalaenum (allansoni (apfelbecki (udominatum, parvum))))) ((((alboguttatum, aegyptium) quinqueguttatum) annulatipes)). Only in the titicacae, halterale, pullum and apfelbecki groups are the larvae of more than one species described, while one larva is known in each of the subovatum, parascalaenum, aegyptium and quinqueguttatum groups. Three or more pupae are known only from the halterale, pullum, apfelbecki and aegyptium groups. Thus, the tentative nature of the group divisions is obvious. Geographical co‐evolutionary analyses (Brooks parsimony analyses) of the subgenus as a whole and of the major groups are performed and the areas most likely to be part of the original areas estimated. Most probably, eastern South America and Africa were part of the ancestral area. There are multiple sister‐group relationships and generalized tracks between South and East Asia and Africa, between Africa and the Palaearctic region, between South and East Asia, between tropical Brazil and Africa, between East Asia and North America across a former Beringian land bridge, and between the Indo‐West Pacific region and New Zealand, but no evidence for transantarctic relationships.     

The Lepocreadiidae (Digenea) of fishes of the north-east Atlantic: review of the genera Opechona Looss, 1907 and Prodistomum Linton, 1910

The genera Opechona Looss and Prodistomum Linton are redefined: the latter is re-established, its diagnostic character being the lack of a uroproct. Pharyngora Lebour and Neopechona Stunkard are considered synonyms of Opechona, and Acanthocolpoides Travassos, Freitas & Bührnheim is considered a synonym of Prodistomum. Opechona bacillaris (Molin) and Prodistomum [originally Distomum] polonii (Molin) n. comb. are described from the NE Atlantic Ocean. Separate revisions with keys to Opechona, Prodistomum and ‘Opechona-like’ species incertae sedis are presented. Opechona is considered to contain: O. bacillaris (type-species), O. alaskensis Ward & Fillingham, O. [originally Neopechona] cablei (Stunkard) n. comb., O. chloroscombri Nahhas & Cable, O. occidentalis Montgomery, O. parvasoma Ching sp. inq., O. pharyngodactyla Manter, O. [originally Distomum] pyriforme (Linton) n. comb. and O. sebastodis (Yamaguti). Prodistomum includes: P. gracile Linton (type-species), P. [originally Opechona] girellae (Yamaguti) n. comb., P. [originally Opechona] hynnodi (Yamaguti) n. comb., P. [originally Opechona] menidiae (Manter) n. comb., P. [originally Pharyngora] orientalis (Layman) n. comb., P. polonii and P. [originally Opechona] waltairensis (Madhavi) n. comb. Some species are considered ‘Opechona-like’ species incertae sedis: O. formiae Oshmarin, O. siddiqii Ahmad, 1986 nec 1984, O. mohsini Ahmad, O. magnatestis Gaevskaya & Kovaleva, O. vinodae Ahmad, O. travassosi Ahmad, ‘Lepidapedon’ nelsoni Gupta & Mehrotra and O. siddiqi Ahmad, 1984 nec 1986. The related genera Cephalolepidapedon Yamaguti and Clavogalea Bray and the synonymies of their constituent species are discussed, and further comments are made on related genera and misplaced species. The new combination Clavogalea [originally Stephanostomum] trachinoti (Fischthal & Thomas) is made. The taxonomy, life-history, host-specificity and zoogeography of the genera are briefly discussed.     

Socioeconomic Value and Growth of Naturalized <Emphasis Type="Italic">Musa balbisiana</Emphasis> L. A. Colla Leaves in Honduras

Socioeconomic Value and Growth of Naturalized Musa balbisiana L. A. Colla Leaves in Honduras. Musa balbisiana (Musaceae) is a seed–producing diploid banana indigenous to Southeast Asia. After it was introduced to Honduras it became naturalized in nearby second–growth areas of the north coast. Local residents were quick to recognize the socioeconomic value of these wild banana leaves as a wrap for traditional nacatamales. To estimate the monetary value and to provide preliminary data on sustainable harvest of these leaves, interviews and field research were undertaken in 2009. From July to September of that year, each of 38 harvesters averaged a weekly sale of 4,400 cut, de–veined, and blanched M. balbisiana leaves. This weekly harvest sold for Lempiras (Lps.) 550.00 or ca. U.S. 30.00 to truckers, who transported them to major markets. The number of leaves produced in three months was estimated by two techniques: 1) The traditional cut of the entire pseudostem and 2) a careful cut to only remove useful leaves. The number of useful leaves cut at the onset of the study and three months later was 11 and 13 for techniques 1 and 2, respectively. This difference was not significant, but the more careful method did yield significantly wider, longer, and a greater number of total leaves (useful plus immature). This is the first field study to estimate leaf production by naturalized < i > M. balbisiana < /i > plants in Honduras. All leaves are currently harvested from wild populations and no sustainable management plans exist. The socioeconomic value and cultural use of < i > M. balbisiana < /i > leaves in Honduras is an example of an exotic species that has important socioeconomic benefits. This naturalized < i > Musa < /i > appearsM. balbisiana plants in Honduras. All leaves are currently harvested from wild populations and no sustainable management plans exist. The socioeconomic value and cultural use of M. balbisiana leaves in Honduras is an example of an exotic species that has important socioeconomic benefits. This naturalized Musa appears to have few of the negative impacts typically attributed to exotic plants.     

Lack of Candida africana and Candida dubliniensis in vaginal Candida albicans isolates in Turkey using HWP1 gene polymorphisms

Candida africana differs from the common strains of C. albicans and C. dubliniensis morphologically, physiologically, genetically, and, in particular, clinically. This fungal pathogen is primarily recovered from genital specimens, especially in vaginal specimens. In this investigation, we reexamined 195 vaginal C. albicans isolates for the presence of C. africana and C. dubliniensis by using hyphal wall protein 1 (HWP1) gene polymorphisms. All study isolates were confirmed to be C. albicans, and none were verified as either C. africana or C. dubliniensis. In conclusion, the HWP1 gene polymorphisms offer a useful tool in the discrimination of C. africana, C. albicans, and C. dubliniensis. Further studies may highlight the pathogenesis and importance of this yeast in vulvovaginal candidiasis.     

东方蜜蜂微孢子虫N6-腺苷特异性甲基化转移酶基因的克隆、分子特性及表达模式北大核心

【目的】东方蜜蜂微孢子虫(Nosme ceranae)专性侵染成年蜜蜂导致微孢子虫病,给养蜂生产造成很大损失。目前,东方蜜蜂微孢子虫的N6-腺苷特异性甲基化转移酶(N6-adenine-specific methyltransferase,N6AMT)基因NcN6AMT的研究仍然缺失。本研究对NcN6AMT的编码序列(coding sequence,CDS)区进行克隆,并解析NcN6AMT蛋白的理化性质和分子特性,进而测定东方蜜蜂微孢子虫侵染意大利蜜蜂(Apis mellifera ligustica)和中华蜜蜂(Apis cerana cerana)工蜂过程中NcN6AMT的相对表达量,以期丰富NcN6AMT的信息,并为探究东方蜜蜂微孢子虫侵染过程NcN6AMT的功能及表观调控机制提供基础。【方法】采用Protparam和ProtScale软件对NcN6AMT进行等电点和亲水性分析。通过SignalP 5.0、NetPhos 3.1、TMHMM-2.0、SOPMA和SWISS-MODEL等软件分别预测NcN6AMT的信号肽、磷酸化位点、跨膜结构域、二级结构和三级结构。使用WoLF PSORT II软件预测NcN6AMT的亚细胞定位。根据N6AMT氨基酸序列,通过TBtools软件对智人(Homo sapiens)、小鼠(Mus musculus)、褐飞虱(Nilaparvata lugens)、兔脑炎微孢子虫(Encephalitozoon cuniculi)、肠脑炎微孢子虫(Encephalitozoon intestinalis ATCC 50506)、蚱蜢脑炎微孢子虫(Encephalitozoon romaleae SJ-2008)、美洲思普雷格孢虫(Spraguea lophii 42_110)、家蚕微孢子虫(Nosema bombycis CQ1)、隐生菱形藻(Nitzschia inconspicua)和东方蜜蜂微孢子虫(Nosema ceranae)的N6AMT进行结构域预测和分析。利用MEME软件和MEGA 11.0软件进行东方蜜蜂微孢子虫和其他物种N6AMT的保守基序预测及进化树构建。采用实时荧光定量聚合酶链式反应(real-time fluorescence quantitative polymerase chain reaction,RT-qPCR)检测NcN6AMT在东方蜜蜂微孢子虫侵染意大利蜜蜂和中华蜜蜂工蜂过程的相对表达量。【结果】通过PCR扩增出大小约500 bp的目的片段,克隆测序结果显示其与GenBank数据库收录的预测序列一致;NcN6AMT蛋白的分子量约为18.7 kDa,分子式为C845H1374N214O249S6,理论等电点为5.88,脂溶系数是119.76,不稳定系数为37.47,平均亲水系数为0.025,含166个氨基酸和15个磷酸化位点,不含典型的跨膜结构域和信号肽,可同时定位于细胞质、线粒体、细胞核和液泡膜;NcN6AMT含1个甲基转移酶小结构域(methyltransferase small domain,MTS),该结构域同样存在于家蚕微孢子虫和兔脑炎微孢子虫等8个其他物种的N6AMT;在东方蜜蜂微孢子虫、兔脑炎微孢子虫、肠脑炎微孢子虫和蚱蜢脑炎微孢子虫的N6AMT中均预测到5个相同的保守基序;NcN6AMT与家蚕微孢子虫、肠脑炎微孢子虫、兔脑炎微孢子虫和蚱蜢脑炎微孢子虫的N6AMT序列一致性达到70.92%;东方蜜蜂微孢子虫和家蚕微孢子虫的N6AMT在系统进化树上聚为一支;东方蜜蜂微孢子虫接种后1–4 d,NcN6AMT在意大利蜜蜂和中华蜜蜂工蜂中肠内均呈现先上升后下降的表达趋势。【结论】成功克隆到NcN6AMT基因的CDS区,明确了NcN6AMT蛋白的理化性质和分子特性,并揭示东方蜜蜂微孢子虫和家蚕微孢子虫的N6AMT蛋白具有较高的保守性,NcN6AMT在东方蜜蜂微孢子虫侵染意大利蜜蜂和中华蜜蜂工蜂的第一个增殖周期(1–4 dpi)内动态表达且均呈上升-下降的表达模式。     

Phylogeny of the orb-weaving spider family Araneidae (Araneae: Araneoidea)

We present a new phylogeny of the spider family Araneidae based on five genes (28S, 18S, COI, H3 and 16S) for 158 taxa, identified and mainly sequenced by us. This includes 25 outgroups and 133 araneid ingroups representing the subfamilies Zygiellinae Simon, 1929, Nephilinae Simon, 1894, and the typical araneids, here informally named the “ARA Clade”. The araneid genera analysed here include roughly 90% of all currently named araneid species. The ARA Clade is the primary focus of this analysis. In taxonomic terms, outgroups comprise 22 genera and 11 families, and the ingroup comprises three Zygiellinae and four Nephilinae genera, and 85 ARA Clade genera (ten new). Within the ARA Clade, we recognize ten informal groups that contain at least three genera each and are supported under Bayesian posterior probabilities (≥ 0.95): “Caerostrines” (Caerostris, Gnolus and Testudinaria), “Micrathenines” (Acacesia, Micrathena, Ocrepeira, Scoloderus and Verrucosa), “Eriophorines” (Acanthepeira, Alpaida, Eriophora, Parawixia and Wagneriana), “Backobourkiines” (Acroaspis, Backobourkia, Carepalxis, Novakiella, Parawixia, Plebs, Singa and three new genera), “Argiopines” (Arachnura, Acusilas, Argiope, Cyrtophora, Gea, Lariniaria and Mecynogea), “Cyrtarachnines” (Aranoethra, Cyrtarachne, Paraplectana, Pasilobus and Poecilopachys), “Mastophorines” (Celaenia, Exechocentrus and Mastophora,), “Nuctenines” (Larinia, Larinioides and Nuctenea), “Zealaraneines” (Colaranea, Cryptaranea, Paralarinia, Zealaranea and two new genera) and “Gasteracanthines” (Augusta, Acrosomoides, Austracantha, Gasteracantha, Isoxya, Macracantha, Madacantha, Parmatergus and Thelacantha). Few of these groups are currently corroborated by morphology, behaviour, natural history or biogeography. We also include the large genus Araneus, along with Aculepeira, Agalenatea, Anepsion, Araniella, Cercidia, Chorizopes, Cyclosa, Dolophones, Eriovixia, Eustala, Gibbaranea, Hingstepeira, Hypognatha, Kaira, Larinia, Mangora, Metazygia, Metepeira, Neoscona, Paraplectanoides, Perilla, Poltys, Pycnacantha, Spilasma and Telaprocera, but the placement of these genera was generally ambiguous, except for Paraplectanoides, which is strongly supported as sister to traditional Nephilinae. Araneus, Argiope, Eriophora and Larinia are polyphyletic, Araneus implying nine new taxa of genus rank, and Eriophora and Larinia two each. In Araneus and Eriophora, polyphyly was usually due to north temperate generic concepts being used as dumping grounds for species from southern hemisphere regions, e.g. South-East Asia, Australia or New Zealand. Although Araneidae is one of the better studied spider families, too little natural history and/or morphological data are available across these terminals to draw any strong evolutionary conclusions. However, the classical orb web is reconstructed as plesiomorphic for Araneidae, with a single loss in “cyrtarachnines”–“mastophorines”. Web decorations (collectively known as stabilimenta) evolved perhaps five times. Sexual dimorphism generally results from female body size increase with few exceptions; dimorphic taxa are not monophyletic and revert to monomorphism in a few cases.     

Dissection of <Emphasis Type="Italic">cry</Emphasis> Gene Profiles of <Emphasis Type="Italic">Bacillus thuringiensis</Emphasis> Isolates in Taiwan

On the basis of the newly revised nomenclature system of cry genes, the PCR amplification method has been adopted to resolve the cry gene combinations of 294 Bacillus thuringiensis isolates from five selected areas of Taiwan. Our results indicate that cry1 (especially cry1A + 1B + 1F) and cry2 were the most abundant cry genes in Taiwan. In contrast, cry3 and cry6 genes were detected only on Yang Ming Mountain, while the cry13 gene was found only on Snow Mountain. In addition, some distinctive combinations of cry genes were detected in distinct areas of Taiwan, such as cry1C, cry1D, cry1C + 1D, cry4, cry1 + 4, cry1 + 11, cry4 + 11, and cry1 + 4 + 11 in the Taipei area; cry1A + 1C + 1F in the Taichung area; cry1E and cry1A + 1B + 1I on Yang Ming Mountain; cry1 + 13, cry1 + 2 + 11, and cry1 + 2 + 13 on Snow Mountain; and cry1 + 5 and cry1 + 2 + 5 on Jade Mountain. These data clearly indicate that the distribution of cry gene combinations of B. thuringiensis isolates seems to be geographically related.     

Alternative splicing of the <Emphasis Type="Italic">antitrypsin</Emphasis> gene in the silkworm, <Emphasis Type="Italic">Bombyx mori</Emphasis>

Alternative splicing plays an important role in expanding protein diversity. In the present study, different splice variants of the antitrypsin gene (sw-AT) in the silkworm were identified by bioinformatics analyses using expressed sequence tags and genomic information. Four splice variants were obtained by RT-PCR with suitably designed primers, confirmed by sequencing, and designated as sw-AT-1, sw-AT-2, sw-AT-3, and sw-AT-4. The sw-AT gene contains 10 exons and nine introns. The splice variants differ in exon 9, with sw-AT-1, sw-AT-2, and sw-AT-3 using different versions of the exon, namely exon 9a, 9b, and 9c, respectively. In sw-AT-4, exon 9 consists of the combination of exons 9b and 9c. The expression patterns of the four isoforms in different tissues, at different developmental stages, and under different stress conditions (temperature, starvation, and mycotic infection) were characterized and quantified. The sw-AT isoforms showed tissue-specific expression patterns, with sw-AT-1 present in almost all tissues and sw-AT-4 found in only a few tissues. The four isoforms were predominantly expressed in the fat body, body wall, and testes of larvae, and exhibited similar expression profiles during development of the fat body. Among the stress treatments, low temperature had the greatest effect on isoform expression, and expression was also upregulated with mycotic infection.     

Karyological studies of Japanese ants (Hymenoptera,Formicidae)

The karyotypes of nine Japanese ants in three subfamilies (Ponerinae, Formicinae, and Myrmicinae) were successfully analysed by the improved squash technique. Three ponerine species had 2n=7 and n=4 (Ponera scabra), 2n=22 (Brachyponera sinensis), and 2n=28 and n=14 (Cryptopone sauteri). Four formicine species had 2n=18 and n=9 (Camponotus sp. and C. tokioensis), 2n=26 and n=13 (Camponotus japonicus), and 2n=30 and n=15 (Lasius niger). Two myrmicine species had 2n=18 and n=9 (Leptothorax congruus), and 2n=37, 38, 39, and n=17, 18, 19, 20 (Pheidole nodus). It was found that the variation of chromosome number observed in P. nodus was caused by Robertsonian type polymorphism.     

Checklist of the freshwater fishes of Armenia,Azerbaijan and Georgia

We present a critical checklist of freshwater fish species found so far in the countries of Armenia, Azerbaijan and Georgia. In total 119 freshwater fishes are recorded. There are 40, 86 and 96 species currently known for Armenia, Azerbaijan and Georgia respectively. From these 119 species, seven are endemic and seven species are alien. From the alien species, only three (Carassius gibelio, Gambusia holbrooki and Pseudorasbora parva) can be considered as widespread and invasive. There are four species (Gasterosteus aculeatus, Gobio artvinicus, Perca fluviatilis and Salmo gegarkuni) that are translocated within the region. Seven species are confirmed or recorded for the first time including G. artvinicus and Oxynoemacheilus veyselorum for Armenia, Azerbaijan and Georgia, Capoeta kaput and Rhinogobius lindbergi for Azerbaijan and Georgia, Capoeta razii for Azebaijan, Oxynoemacheilus cemali and Squalius agdamicus for Georgia. In this checklist, Acipenser colchicus is treated as a synonym of Acipenser persicus. Sand smelts of the Black and Caspian Sea basin are identified as Atherina caspia and Clupeonella caspia is treated as a synonym of Clupeonella cultriventris. Coregonus sevanicus is listed as Coregonus sp. until the situation of Sevan whitefish is better understood. Capoeta sevangi and Capoeta ekmekciae are synonyms of Capoeta capoeta. The fish often identified as Capoeta capoeta gracilis from rivers south of the Kura most likely belong to C. razii. The Black and Caspian Sea Rutilus populations are treated as conspecific, therefore R. kutum is a junior synonym of R. frisii. Oxynoemacheilus veyseli is valid as O. veyselorum. We list the alien Rhinogobius species as R. lindbergi, however the name is provisional and needs further confirmation. All Squalius species from the Kura River drainage are identified as S. agdamicus, however in the Aras, it is replaced by S. turcicus. Squalius orientalis is treated as a valid species restricted to the eastern Black Sea basin. The four forms of Lake Sevan trout (Salmo ischchan, S. gegarkuni, S. danilewskii and S. aestivalis) are treated as valid species, two of them (S. ischchan and S. danilewskii) are extinct. Rutilus sojuchbulagi from Azerbaijan is also extinct.     

Hemiuridae (Digenea) from marine fishes of the southern Indian Ocean: Dinurinae,Elytrophallinae, Glomericirrinae and Plerurinae

The following species are described, figured and/or recorded from regions of the southern Indian Ocean: Dinurus longisinus from Coryphaena hippurus, Cape Province and Western Australia and immature in Carangoides gymnostethoides, Western Australia; Ectenurus trachuri from Trachurus declivis, Tasmania, Erilepturus tiegsi from Platycephalus endrachtensis, Pomatomus saltator and Arripis georgianus, Western Australia and Sphyraena novaehollandiae, Tasmania; Tubulovesicula angusticauda (with eight new synonyms) from Trachichthodes gerrardi, South Australia and Gymnothorax woodwardi, Saurida undosquamis and Argyrops spinifer, Western Australia; Elytrophalloides oatesi from Meuschenia freycineti and Aldrichetta forsteri, South Australia; Elytrophalloides humerus n. sp. from Trachinotus botla, Natal; Lecithocladium angustiovum (with four new synonyms) from Rastrelliger kanagurta, Natal; Glomericirrus amadai from Hoplostethus atlanticus, Tasmania; Plerurus digitatus (with 17 new synonyms) from Euthynnus affinis, Scomberomorus commerson, Thunnus albacares, Scomberoides commersonianus, Alectis ciliaris, Pomatomus saltator, Saurida undosquamis, Rachycentron canadum, Natal and Lichia amia and Pomatomus saltator, Cape Province and Carangoides gymnostethoides, Western Australia; Synapto-bothrium sp. from Pomatomus saltator, Western Australia.     

An annotated list of species of the Proteocephalus Weinland, 1858 aggregate sensu de Chambrier et al. (2004) (Cestoda: Proteocephalidea), parasites of fishes in the Palaearctic Region, their phylogenetic relationships and a key to their identification

A list and key to the identification of valid species of tapeworms of the Proteocephalus Weinland, 1858 aggregate sensu de Chambrier et al. (2004), i.e. species of the genus occurring in fresh- and brackish-water fishes in the Palaearctic Region, are provided, with data on their hosts and geographical distribution. Instead of 32 taxa listed by Schmidt (1986) and subsequent authors, only the following 14 species are considered to be valid: P. ambiguus (Dujardin, 1845) (type-species); P. cernuae (Gmelin, 1790); P. filicollis (Rudolphi, 1802); P. fluviatilis Bangham, 1925; P. gobiorum Dogiel & Bychowsky, 1939; P. longicollis (Zeder, 1800); P. macrocephalus (Creplin, 1825); P. midoriensis Shimazu, 1990; P. percae (Müller, 1780); P. plecoglossi Yamaguti, 1934; P. sagittus (Grimm, 1872); P. tetrastomus (Rudolphi, 1810); P. thymalli (Annenkova-Chlopina, 1923); and P. torulosus (Batsch, 1786). An analysis of sequences of the nuclear genes (ITS2 and V4 region of 18S rDNA) revealed the following phylogenetic relationships for these taxa: P. torulosus ((P. midoriensis, P. sagittus) (P. fluviatilis (P. filicollis, P. gobiorum, P. macrocephalus)) (P. cernuae, P. plecoglossi, P. tetrastomus ((P. longicollis, P. percae) (P. ambiguus, P. thymalli)))). P. pronini Rusinek, 2001 from grayling Thymallus arcticus nigrescens is synonymised with P. thymalli. P. esocis La Rue, 1911 is apparently invalid but its conspecificity with either P. percae or P. longicollis could not be confirmed due to the absence of the scolex in the holotype and the unavailability of other material for morphological and molecular studies. P. osculatus (Goeze, 1782) has recently been transferred to Glanitaenia de Chambrier, Mariaux, Vaucher & Zehnder, 2004. The validity of the genus is supported by the position of G. osculata within the Proteocephalidea, based on molecular data, as well as its morphology and nature of the definitive host (the European wels Silurus glanis). P. hemispherous Rahemo & Al-Niaeemi, 2001, described from S. glanis in Iraq, is transferred to Postgangesia Akhmerov, 1960 as Postgangesia hemispherous (Rahemo & Al-Niaeemi, 2001) n. comb.     

Therps16 intron and the phylogeny of theRubioideae (Rubiaceae)

The phylogeny of the subfamilyRubioideae (Rubiaceae) was estimated from sequence variation in therps16 intron (cpDNA) in 143 ingroup and 5 outgroup taxa. The analysis largely confirms a recent one based onrbcL sequences, but branch support is often much stronger. Three of the traditional subfamilies are supported,Rubioideae, Cinchonoideae s. str., andIxoroideae s. l. while there is no support forAntirheoideae. TheRubioideae are the sister group of all otherRubiaceae and comprise the tribesAnthospermeae, Coccocypseleae, Cruckshanksieae, Coussareeae, Gaertnereae, Hedyotideae, Knoxieae, Morindeae, Ophiorrhizeae, Paederieae, Pauridiantheae, Perameae, Psychotrieae, Rubieae, Spermacoceae, Theligoneae, andUrophylleae. TheHamelieae andHillieae belong to theCinchonoideae. Rachicallis andSiemensia should be transferred from theHedyotideae to theCinchonoideae. ThePauridiantheae, Urophylleae, Ophiorrhizeae, andRaritebe form the basalmost subclade of theRubioideae. The second basalmost clade consists of the generaLasianthus andPerama. The third basalmost clade consists of the tribesCoussareeae, Coccocypseleae andCruckshanksieae, and the generaDeclieuxia andHindsia. The tribesKnoxieae, Anthospermeae, Argostemmateae, Paederieae, Theligoneae, Rubieae, Hedyotideae, andSpermacoceae are members of one clade. TheKnoxieae are monophyletic ifOtiophora, Otomeria, andPentas are included. The tribeAnthospermeae is supported as monophyletic, but its subtribes are not. ThePaederieae, together withTheligonum, form a paraphyletic grade basal to theRubieae. TheHedyotideae, includingSchismatoclada, form a grade at the base of theSpermacoceae. TheGaertnereae are monophyletic and distinct from thePsychotrieae. TheMorindeae are monophyletic and includeDamnacanthus andMitchella. Schradera is the sister group of theMorindeae. ThePsychotrieae are monophyletic when theGaertnereae, Lasianthus, andDeclieuxia are excluded. The recognition of a subtribeHydnophytineae leaves the rest of thePsychotrieae paraphyletic.Psychotria is paraphyletic with respect to all other genera of the tribe. Approximately 50 genera are here classified for the first time based on molecular data.     

Phylogenetic revision of the North American Asidini (Coleoptera: Tenebrionidae)

The asidine darkling beetles (Coleoptera: Tenebrionidae: Asidini) are a morphologically diverse tribe of flightless tenebrionids found in many arid and sub‐arid habitats around the world. The 260 currently described North American species are contained in 27 genera, all of which are restricted to the western half of the continent. Evolutionary relationships within and between the North American Asidini (Coleoptera: Tenebrionidae) genera were reconstructed using partial sequences of mitochondrial cytochrome c oxidase I (COI) (660 bp) and nuclear ribosomal 28S (D2 region) (492 bp), and 100 phenotypic characters for 50 North American asidine species, representing 20 of the 27 currently described genera and 1 new genus. Species from two additional tenebrionid tribes (Branchini and Coniontini) and the South American asidine genus Cardigenius were chosen as outgroups. Analyses were performed using maximum parsimony and Bayesian inference methods. Clade support was inferred based on the posterior probability distribution of tree topologies, nonparametric bootstrap analysis, and partitioned Bremer support indices. The generic classification of the North American Asidini is revised based on the results, with ten genera recognized. Seven current genera: Craniotus LeConte, Heterasida Casey, Litasida Casey, Microschatia Solier, Pelecyphorus Solier, Philolithus Lacordaire, Stenomorpha Solier, are redescribed, and Ardamimicus Smith gen.n ., Ferveoventer Smith gen.n . and Micrasida Smith gen.n . are described, including Ardamimicus cognatoi Smith sp.n ., Ferveoventer browni Smith sp.n . and Micrasida obrienorum Smith sp.n . Twenty current genera are treated as subgenera pending further analyses: Philolithus Lacordaire with subgenera Glyptasida Casey, Gonasida Casey, Herthasida Wilke and Tisamenes Champion; Pelecyphorus Solier, with subgenera: Astrotus LeConte, Parasida Casey (= Plesiasida nom.n ), Poliorcetes Champion, Sicharbas Champion, Stenosides Solier, Ucalegon Champion and Zaleucus Champion, and Stenomorpha Solier with subgenera Asidina Casey, Asidopsis Casey, Bothrasida Casey, Megasida Casey, Notiasida Casey, Platasida Casey, Pycnomorpha Motschulsky, Stethasida Casey and Trichiasida Casey; all stat.rev .     

Further studies on Egyptian soil fungi: Succession of sugar and osmophilic fungi in soil amended with five organic substrates

The sugar and osmophilic fungal composition of soils amended with five organic substrates (newspaper, orange peel, bromegrass leaves, wheat straw and wood sawdust) was estimated after 2, 4, 6, 8 and 10 weeks using the dilution plate method on glucose and 50% sucrose Czapek's agar media. Wheat straw was the best substrate for total counts of both sugar and osmophilic fungi followed by newspaper, bromegrass leaves, wood sawdust and orange peel. Wood sawdust supported the highest average counts of total sugar fungi, Fusarium, Mucor, Scopulariopsis, Trichoderma and Trimmatostroma spp.; Newspaper, of Aspergillus (8 spp.), Penicillium (4 spp.) and Chaetomium sp. bromegrass leaves of Cladosporium sp., Humicola sp. and Sporotrichum sp.; orange peel, ofAlternaria sp., Circinella sp. and Stachybotrys sp.; and wheat straw, of Botryotrichum sp. and Myrothecium sp. Bromegrass leaves and orange peel supported the highest average counts of total osmophilic fungi, Aspergillus (10 spp.), Cladosporium sp. Paecillomyces sp. and Rhizopus sp.; and of Stemphylium sp., Trichoderma sp., Humicola sp. and Circinella sp. respectively; wheat straw, of Epicoccum sp., Scopulariopsis sp. and Trichothecium sp.; newspaper, of Penicillium (4 spp.) and Alternaria sp.; and wood sawdust of Curvularia sp. and Fusarium (3 spp.). The best colonizers throughout the experimental periods were Aspergilus and Penicillium spp.     

Species boundaries and interrelationships of two closely related sympatric diploid wild potato species, Solanum astleyi and S. boliviense, based on RAPDs

 The more than 200 wild and cultivated species relatives of potato (Solanum sect. Petota) present a valuable germplasm base for cultivar improvement. However, species boundaries and interrelationships within sect. Petota are controversial, inhibiting the efficient organization of the many germplasm collections of these species. One controversy involves questions of species boundaries and interrelationships of S. astleyi and S. boliviense. Solanum boliviense is narrowly endemic to two Departments in southern Bolivia, and S. astleyi is known only from one site entirely within the range of this species, where they co-occur. Both species are diploid and morphologically very similar. Artificial hybrids between them are fully fertile, and the species putatively hybridize naturally. These data have been interpreted to designate them as separate species or as S. astleyi an ecotype of S. boliviense. Putative progenitors of S. astleyi are S. boliviense, S. megistacrolobum subsp. megistacrolobum, and S. megistacrolobum subsp. toralapanum. We evaluated interrelationships among these species with random amplified polymorphic DNA’s (RAPDs) generated for 2 accessions of S. astleyi and 14 accessions of S. boliviense. These represent the entire geographic range of the former species and nearly the entire range of the latter. We also analyzed 1 accession each of S. acaule subsp. acaule, S. acaule subsp. aemulans, S. albicans, S. berthaultii, S. megistacrolobum subsp. megistacrolobum, S. megistacrolobum subsp. toralapanum, S. raphanifolium, S. sogarandinum, and S. sparsipilum. Phenetic analyses of the RAPD data show S. astleyi and S. boliviense to form two distinct groups and to be more similar to each other than to any of the other species investigated, suggesting that S. astleyi and S. boliviense are sister taxa. The divergence of S. astleyi and S. boliviense relative to other species examined suggests that they are worthy of taxonomic recognition at the subspecies, rather than species level, and we propose the new combination S. boliviense subsp. astleyi.
