Taxonomic update of Clitocybula sensu lato with a new generic classification

The taxonomy and phylogeny of the hydropoid clade (genera Clitocybula s.l., Megacollybia, Leucoinocybe gen. nov., Hydropus, Trogia, Gerronema, Porotheleum and Lignomphalia gen. nov.) in Europe is studied using morphological and molecular approaches; the first three genera in detail including all known European species. Only two European species remain in Clitocybula s.str., Clitocybula lacerata and Clitocybula familia. The European C. lacerata is a species complex which should be treated as C. lacerata agg. at the current state of knowledge. A neotype originating from type area was designated to fix the application of the name. The presence of American species Clitocybula abundans in Europe is insufficiently proved. “Clitocybula dryadicola ? belongs to the genus Hydropus, and Clitocybula tilieti has an unclear systematic position. The results showed that Megacollybia and Leucoinocybe represent independent genera separated from Clitocybula. The genus Leucoinocybe is validly published with two European species, Leucoinocybe lenta and Leucoinocybe taniae. “Clitocybula flavoaurantia” proved to be conspecific with the latter species. The genus Lignomphalia is published for “Pseudoomphalina lignicola”, a lignicolous omphalinoid species. The Indian “Clitocybula sulcata” is transferred to Leucoinocybe and “Clitocybula atrialba” to Gerronema. The first European records of Megacollybia marginata are published.     

Phylogenetic analysis of the sharpshooter genus Subrasaca Young, 1977 (Hemiptera,Cicadellidae, Cicadellini)

The South American sharpshooter genus Subrasaca comprises 14 species. Some species of this genus are quite common in the Brazilian Atlantic Rainforest. In this paper, a phylogenetic analysis of Subrasaca, based on a matrix of 20 terminal taxa and 72 morphological characters of the head, thorax, and male and female genitalia, is presented. The analysis yielded six equally most parsimonious trees (197 steps, CI = 0.6091, RI = 0.5722, and RC = 0.3486). The results suggest that Subrasaca is a monophyletic taxon, although the genus branch is not robust. The clade showing the highest bootstrap and Bremer scores is formed by species with longitudinal dark brown to black stripes on the forewings (Subrasaca bimaculata, Subrasaca constricta, Subrasaca curvovittata, and Subrasaca flavolineata), followed by Subrasaca atronasa + Subrasaca austera.     

Eucharitidae (Hymenoptera,Chalcidoidea), a family new to the fauna of Saudi Arabia,with the description of the previously unknown male of Eucharis (Psilogastrellus) affinis Bou?ek

The family Eucharitidae (Hymenoptera: Chalcidoidea) is recorded for the first time for the fauna of Saudi Arabia based on Hydrorhoa caffra (Westwood) and Eucharis (Psilogastrellus) affinis Bouček. The record of Hydrorhoa caffra suggests that Al-Baha and Asir provinces should be considered as part of the Afrotropical rather than the Palaearctic region. The previously unknown male of Eucharis affinis Bouček is described and figured. Macrophotographs of the species are provided.     

New records of Lophoproctus coecus Pocock, 1894 (Diplopoda,Polyxenida, Lophoproctidae) extend the range of the genus Lophoproctus

The geographic distribution of the genus Lophoproctus Pocock, 1894 has greatly expanded with new records of the species Lophoproctus coecus Pocock, 1894, together with the reassignment of a number of millipedes formerly identified as Lophoproctus lucidus (Chalande, 1888). Lophoproctus coecus was found to be the sole representative of the family Lophoproctidae in collections examined from Crimea and the Caucasian region. The species was also identified from Iran and Kyrgyzstan. Lophoproctus specimens collected in Italy by Verhoeff were reassigned as Lophoproctus coecus with the exception of one specimen of Lophoproctus jeanneli (Brölemann, 1910) from Capri. These data were combined with all available information from the literature to look at the pattern of distribution of the four species in the genus. The range of the genus Lophoproctus extends from Portugal to Central Asia. Lophoproctus coecus is widespread from Italy eastward, while the morphologically very similar species Lophoproctus lucidus is confined to France and northern Africa. The two species have a narrow overlap in the Alpes Maritimes region of France. Lophoproctus jeanneli has a scattered coastal distribution around the Mediterranean Sea. The troglobitic species Lophoproctus pagesi (Condé, 1982) has only been recorded from a cave on Majorca, Spain.     

A revision of the Afrotropical spider genus Cambalida Simon, 1909 (Araneae,Corinnidae)

The non-mimetic Afrotropical spider genus Cambalida Simon, 1909, placed within a subfamily of predominantly ant-mimicking spiders (Araneae: Corinnidae: Castianeirinae), is revised. Three species are transferred from Castianeira Keyserling, 1879 to Cambalida: Cambalida deminuta (Simon, 1909), comb. n., Cambalida fulvipes (Simon, 1896), comb. n. and Cambalida loricifera (Simon, 1885), comb. n.. A fourth species, Cambalida fagei (Caporiacco, 1939), comb. n., is transferred from Brachyphaea Simon, 1895 to Cambalida. Two species, Castianeira depygata Strand, 1916, syn. n. and Cambalida mestrali Lessert, 1921, syn. n., are considered junior synonyms of Cambalida fulvipes. The males of Cambalida deminuta and Cambalida loricifera are redescribed and their unknown females are described for the first time. The female and male of Cambalida fulvipes and Cambalida coriacea Simon, 1909 are also redescribed. The type material of the type species of the genus, Cambalida insulana Simon, 1909 from Pagalu (Annobon) Island, is lost, and only immature specimens have been subsequently collected from a nearby island. The species is regarded as a nomen dubium until fresh adult material can be collected. A replacement name, Cambalida simoni nom. n. is proposed for Cambalida fulvipes Simon, 1909, the latter being a secondary junior homonym of Cambalida fulvipes (Simon, 1896). The type material of this species is also lost and it is too considered nomen dubium. The following new species are described: Cambalida compressa sp. n. from West Africa, Cambalida dippenaarae sp. n. from southern Africa, Cambalida griswoldi sp. n. and Cambalida lineata sp. n. from Madagascar, and Cambalida unica sp. n. from Cameroon. Notes are provided on the biology of each species and the distribution of the genus in the Afrotropical Region.     

Description of Telamoptilia grewiae sp. n. and the consequences for the definition of the genera Telamoptilia and Spulerina (Lepidoptera,Gracillariidae, Gracillariinae)

The new species Telamoptilia grewiae, reared from leafmines on Grewia biloba (Malvaceae) is described with details on adult and immature stages. The larval head and the pupa are described for the first time in Telamoptilia Kumata & Kuroko, 1988, and are illustrated with scanning electron micrographs and line drawings. Photographs of adult habitus, wing venation, male and female genitalia, as well as host plant and mines are provided. The apomorphic adult and larval characters of the new species in Telamoptilia are discussed in relation to the recognition of the genera Telamoptilia and Spulerina Vári, 1961.     

Complete Mitochondrial Genome of Anoplocephala magna Solidifying the Species

The 2 species of the genus Anoplocephala (Anoplocephalidae), A. perfoliata and A. magna, are among the most important equine cestode parasites. However, there is little information about their differences at the molecular level. The present study revealed that the mitochondrial (mt) genome of A. magna was 13,759 bp in size and 700 bp shorter than that of A. perfoliata. The 2 species includes 2 rRNA, 22 tRNA, and 12 protein-coding genes each. The size of each of the 36 genes was the same as that of A. perfoliata, except for cox1, rrnL, trnC, trnS2(UCN), trnG, trnH, trnQ, and trnP. In the full mitochondrial genome, the sequence similarity was 87.1%. The divergence in the nucleotide and amino acid sequences of individual protein-coding genes ranged from 11.1% to 16% and 6.8% to 16.4%, respectively. The 2 noncoding regions of the mt genome of A. magna were 199 bp and 271 bp in length, while the equivalent regions in A. perfoliata were 875 bp and 276 bp, respectively. The results of this study support the proposal that A. magna and A. perfoliata are separate species, consistent with previous morphological analyses.     

The characterization of N-acetylglucosaminidases from the limpet Patella vulgata (L.)

The α- and β-N-acetylglucosaminidase activity of the limpet Patella vulgata (L.) is due to two enzymes. One of these enzymes hydrolyses both α- and β-N-acetylglucosaminidases and is referred to α,β-N-acetylglucosaminidase. The other is a β-N-acetylglucosaminidase (EC 3.2.1.30). Both enzymes have been isolated and characterized as glycoproteins containing 12% hexose, mainly galactose. The amino acid, neutral sugar and amino sugar content of the two enzymes is very similar, and the main difference lies in the presence of 9% sialic acid in β-N-acetylglucosaminidase. The molecular weight of α,β-N-acetylglucosaminidase is 217 000 and that of β-N-acetylglucosaminidase is 136 000. Evidence has been obtained for the presence of an additional sub-unit in the α,β-enzyme.     

Re-interpreting the biochronology of the La Celia and Los Gargantones mammal sites (Late Miocene,Murcia, Spain)

The biochronological age of the small-mammal populations of Los Gargantones 1, 2 and La Celia (upper Miocene, La Celia sub-basin, Murcia, Spain) is re-interpreted. The presence in Los Gargantones of Occitanomys adroveri, Parapodemus barbarae, Parapodemus cf. gaudryi, Huerzelerimys turoliensis, Atlantoxerus cf. adroveri, and Alilepus evidences a correlation to MN12 (∼7.5–7 Ma) rather than to MN11 (∼9–7.5 Ma), as inferred previously. The assemblage corresponds to that of the more eastern, near-coast sites of Crevillente 8 and 15, situated in the Alicante area. The stratigraphically highest site of La Celia contains Hispanomys adroveri, a species also indicative of MN12. The presence of Castromys cf. littoralis together with an advanced O. adroveri points to a slightly younger age than that of Los Gargantones, approaching that of MN13 sites. The assemblage best matches that of Crevillente 17. Other species described in this paper are Prolagus crusafonti, Prolagus sp., Parasorex cf. ibericus, Panelimnoecus cf. repenningi, and Blarinella aut Petenyia sp. indet.     

DNA sequence of the araBAD-araC controlling region in Salmonella typhimurium LT2

The araB and araC genes of Salmonella typhimurium have been cloned onto the plasmid pBR322. Restriction analysis and subcloning of restriction fragments localized these genes to a 4.4 kb DNA fragment. Complementation analysis revealed that the cloned araB and araC genes from S. typhimurium complemented araB and araC mutant strains of Escherichia coli. Conversely, cloned araB and araC genes from E. coli complemented araB and araC mutant strains of S. typhimurium. The DNA sequences was determined for the S. typhimurium araB and araC controlling region and for the initially translated portions of these genes. The nucleotide sequence of the araB promoter was 87% homologous with the same region in E. coli and contained no deletions or insertions relative to the E. coli sequence. The presumed AUG codon corresponding to the amino terminus of the S. typhimurium araC protein was in the same location as in E. coli. There was, however, considerable divergence from the E. coli sequence preceding the translation start site. The nucleotide sequence of the initial 237 bp in the open reading frame of the S. typhimurium araC gene was 78% homologous with the same sequence in E. coli. By comparison, the amino acid sequence for this region was 91% conserved.     

Pollen morphology of Campanula (Campanulaceae) and allied genera in Iran with special focus on its systematic implication

Pollen grains of 47 taxa of Campanulaceae including 35 taxa of Campanula that represent its five subgenera and nine sections are investigated. Moreover, five species and three subspecies representing three sections in Asyneuma and one species of each genera Legousia, Michauxia, Zeugandra and Theodorovia were studied by light and scanning electron microscopy. The basic shape of the pollen grains was spheroidal. The apertures vary from tri- to hexa-porate. The sculpturing pattern of exine was rugulate-echinate, rugulate-microechinate or in few species rugulate-microreticulate and microechinate. The most valuable characters for subgeneric classification were the length and density of echini. The length of echini were significantly long (> 2 μm) in C. sclerotricha, Legousia falcata and Michauxia laevigata. Pollen grains show low variation in different species of subgen. Rapunculus, but were variable among different species of some groups, such as sect. Rupestres, probably indicating their non-monophyly despite homogeneity with respect to other morphological characters. Pollen morphology does not support recognition of Asyneuma, Legousia, Michauxia, Symphyandra, Theodorovia, and Zeugandra as separated from Campanula, since none of them exhibit any unique feature.     

Molecular phylogeny of Phoma and allied anamorph genera: Towards a reclassification of the Phoma complex

The present generic concept of Phoma is broadly defined, with nine sections being recognised based on morphological characters. Teleomorph states of Phoma have been described in the genera Didymella, Leptosphaeria, Pleospora and Mycosphaerella, indicating that Phoma anamorphs represent a polyphyletic group. In an attempt to delineate generic boundaries, representative strains of the various Phoma sections and allied coelomycetous genera were included for study. Sequence data of the 18S nrDNA (SSU) and the 28S nrDNA (LSU) regions of 18 Phoma strains included were compared with those of representative strains of 39 allied anamorph genera, including Ascochyta, Coniothyrium, Deuterophoma, Microsphaeropsis, Pleurophoma, Pyrenochaeta, and 11 teleomorph genera. The type species of the Phoma sections Phoma, Phyllostictoides, Sclerophomella, Macrospora and Peyronellaea grouped in a subclade in the Pleosporales with the type species of Ascochyta and Microsphaeropsis. The new family Didymellaceae is proposed to accommodate these Phoma sections and related anamorph genera. The present study demonstrated that Phoma radicina, the type species of Phoma sect. Paraphoma and Phoma heteromorphospora, the type species of Phoma sect. Heterospora can be assigned to the Phaeosphaeriaceae and Leptosphaeriaceae respectively.     

Types of species of Apionidae (Coleoptera) described by Carl Peter Thunberg (1743–1828) with description of?a new genus

The type specimens of species of Apionidae described by Carl Peter Thunberg are reviewed and lecto- and paralectotypes are designated for Apion craccae Thunberg, 1813, Apion limbatum Thunberg, 1813, Apion punctigerum Thunberg, 1815 and Apion astragali Thunberg, 1815. A new genus Thunbergapion (type species Apion limbatum Thunberg, 1813) is described, figured and placed in the tribe Aplemonini Kissinger, 1968. The new combination Thunbergapion limbatum (Thunberg, 1813) is proposed. A key to the known South African genera of the tribe is given. The following new synonymies are established: Oxystoma craccae (Linnaeus, 1767) = Apion craccae Thunberg, 1813 syn. n., Ischnopterapion (Ischnopterapion) loti (Kirby, 1808) = Apion punctigerum Thunberg, 1815, syn. n., and Pseudoprotapion astragali (Paykull, 1800) = Apion astragali Thunberg, 1815, syn. n.     

A comparative study of the ori sequences from the mitochondrial genomes of twenty wild-type yeast strains

The ori sequences of the mitochondrial genomes of 20 wild-type strains of Saccharomyces cerevisiae were compared with those of the previously studied strain A (de Zamaroczy et al., 1984). The seven canonical ori sequences of this strain appear to be present in all strains tested, but in most strains ori1 is replaced by an extensively rearranged ori1 ¹ sequence, and an additional ori sequence, ori8, is present between the oxi3 and the 15S RNA genes; one strain, B, lacks ori4. The location and orientation of ori sequences of three strains, B, C and K, were found to be the same as in strain A. The primary structures of four ori sequences from three different strains (ori1 of strain J69-1B, ori3 and ori5 of strain K, ori6 of strain D273-10B) were found to be identical with the corresponding ori sequences previously investigated. Hybridization experiments with different on probes indicated a conservation of ori2–ori7 sequences in all strains tested. The primary structure of a petite genome derived from strain B and carrying ori1 ¹ is reported and discussed.     

New genera,species and records of Phaneropterinae (Orthoptera,Phaneropteridae) from sub-Saharan Africa

The results of the study of many specimens preserved in different European museums are reported. The tribe Terpnistrini Brunner von Wattenwyl, 1878 is resurrected. The distribution of the following species is enhanced: Pardalota asymmetrica Karsch, 1896, Diogena denticulata Chopard, 1954, Diogena fausta (Burmeister, 1838), Plangiopsis adeps Karsch, 1896, Poreuomena sanghensis Massa, 2013 and Tylopsis continua (Walker, 1869). Further, for their peculiar characteristics, two African representatives of the American genus Symmetropleura Brunner von Wattenwyl, 1878 are included in two new genera: Symmetrokarschia africana (Brunner von Wattenwyl, 1878), comb. n. and Symmetroraggea dirempta (Karsch, 1889), comb. n. A new genus and species from the Democratic Republic of Congo, Angustithorax spiniger gen. n., sp. n., and a new genus and species from Tanzania, Arostratum oblitum gen. n., sp. n. are described. Finally Melidia claudiae sp. n. and Atlasacris brevipennis sp. n. are described and compared with related species.     

Pollen morphology of alpine butterworts (Pinguicula L., Lentibulariaceae)

The pollen morphology of Pinguicula alpina, P. arvetii, P. grandiflora subsp. grandiflora, P. grandiflora subsp. rosea, P. hirtiflora, P. leptoceras, P. poldinii, P. reichenbachiana, and P. vulgaris, belonging to the Alpine flora, was studied.The pollen grains, coming from different populations, were investigated using light microscopy and scanning electron microscopy. The pollen size, the shape (P/E ratio), the number of colpori and the exine ornamentation are, for Pinguicula, important diagnostic characters.Pinguicula pollen grains are medium sized (∼ 30 μm), trinucleate, isopolar, radially symmetric. The shape of the grains is variable from oblate spheroidal to prolate spheroidal and they are (4)-5-9-(10)-zonocolporate. The prevalent ornamentation is rugulate-microreticulate, P. alpina has a rugulate-reticulate ornamentation and only P. hirtiflora has a perforate ornamentation.A pollen key, based on micromorphological data, is presented.     

Organization of the nar genes at the chlZ locus

The two membrane-bound respiratory nitrate reductases of Escherichia coli are encoded by distinct operons at two different loci, chlC and chlZ, on the chromosome. The chlZ locus includes a narK homologue, narU, encoding a nitrite extrusion protein, and narZYWV encoding nitrate reductase Z. No apparent homologue to the narXL operon has been found. Homology between narU and narK on the one hand and narZYWV and narGHJI on the other hand is limited to the coding regions.
