A review of the bloodsucking midges of Trinidad and Tobago,West Indies (Diptera:Ceratopogonidae)*

Data are presented recording the presence of 49 species of bloodsucking cerato-pogonids in Trinidad, West Indies. Of these, 45 are Culicoides, one is a Leptoconops, and three belong to Forcipomyia (Lasiohelea). Five species are reported from Tobago: three Culicoides, one Leptoconops, and one Lasiohelea. The males of Culicoides benarrochi and C. fluviatilis are described for the first time, and the female of C. debilipalpis is redescribed. Culicoides filariferus and C. pseudodiabolicus are resurrected from synonymy, and characters are presented distinguishing them from C. diabolicus and C. guttatus. Biological data and keys to genera and species are included.     

Early Jurassic gastropods from England

Abstract: Twenty‐five gastropod taxa are reported from the Early Jurassic (Hettangian to Toarcian) of England. Of these, 14 are identified to species level, and the remaining 11 are treated in open nomenclature. One genus (Lensataphrus) and six species are introduced as new. The new species are Lensataphrus tatei, Lensataphrus tenuis, Tricarilda toddi, Cylindrobullina dorsetensis, Cylindrobullina ventricosa and Consobrinella greeni. The following new combinations are introduced: Cassianopsis hebertana (d’Orbigny, 1852) for Neritopsis hebertana; Cryptaulax abscisum (Terquem and Piette, 1868) for Cerithium abscisum; and Cylindrobullina avena (Terquem, 1855) for Striactaeonina avena. Most of the genera and some of the species are also known from Central Europe (Germany and France). Typical vetigastropod genera that are present in England and Central Europe are Colpomphalus, Costataphrus, Ooliticia, Eucycloscala and Eucycloidea. The caenogastropod genera Levipleura and Cryptaulax are present in both regions, as are the heterobranchs Tricarilda and Cylindrobullina. The heterobranch genus Consobrinella is reported from England for the first time. Gastropods seem to follow the diversity trends of other marine invertebrates during the Early Jurassic. They diversify until the Late Pliensbachian but decrease sharply in number around the Pliensbachian–Toarcian boundary. This may reflect both regional anoxia and a global mass extinction event in the Early Toarcian.     

Some interesting Orthotrichum species from mainland Greece and Evvia

Abstract

Based on collections made by the authors in mainland Greece, including the Peloponnese and the island of Evvia, several Orthotrichum records of interest are documented. Orthotrichum acuminatum, O. philibertii, O. tortidontium, O . hispanicum, O. macrocephalum and O. shawii are reported for the first time from Greece, the last three also being new to the eastern Mediterranean. O. rivulare, O. scanicum, and O. alpestre, hitherto doubtfully recorded, are confirmed for Greece and new localities are given for O. stramineum, for which there are few previous records.     

A contribution to the rust flora (Uredinales) of southern Africa,with an emphasis on Namibia

Five new rust species are described and hitherto unknown spore states for the following seven species are reported: Puccinia desertorum on Evolvulus alsinoides, Uromyces comptus on Merremia bipinnatipartita, Puccinia halsei on Acacia hereroensis, Ravenelia transvaalensis on Acacia mellifera, Puccinia abutili on Abutilon angulatum, on Abutilon cf. austroafricanum, and on Abutilon cf. rehmannii, Puccinia lycii on Lycium sp. and Puccinia turgida on Lycium europaeum and on Lycium cf. oxycarpum. We also examined Uredo combreticola on Combretum cf. engleri, on Combretum hereroense, and on Combretum zeyheri, Puccinia afra on Lycium sp., and Uredopeltis cf. chevalieri on Grewia flavescens. All mentioned rust fungi are described in detail and are shown by line drawings. Selected species are illustrated with SEM-photographs.

Review of the genus Eusterinx Förster, 1869 (Hymenoptera: Ichneumonidae: Orthocentrinae) with descriptions of five new species from South Korea

South Korean species of the genus Eusterinx Förster are reviewed here. Nine species of the genus Eusterinx are found to occur in South Korea, and five species, Eusterinx (E.) elongata sp. nov. , E. (Holomeristus) hirtis sp. nov. , E. (Ischyracis) fulvipes sp. nov. , E. (I.) petiolata sp. nov. and E. (I.) rufithorax sp. nov. , are described. Four more species of Eusterinx from subgenera Divinatrix, Eusterinx and Holomeristus are recorded from South Korea for the first time. Hitherto, unknown male of the Eastern Palaearctic species E. (Divinatrix) kurilensis Humala is described. A key to all known species of the genus Eusterinx occurring in South Korea is provided.     

Phylogenetic relationships of subgenera of the genus Exorista Meigen,with a revision of the Japanese species (Diptera: Tachinidae)

Phylogenetic relationships of the subgenera of Exorista Meigen (Diptera: Tachinidae) are inferred from morphological data. Our results show that the genus Exorista is not monophyletic and that members of the subgenus Spixomyia Crosskey are divided into two clades. Each subgenus is redefined based on male and female morphological features. The Japanese species of Exorista are revised and classified into five subgenera: Adenia Robineau‐Desvoidy, Exorista Meigen, Podotachina Brauer and Bergenstamm, Ptilotachina Brauer and Bergenstamm, and Spixomyia Crosskey. Thirteen species are recognized, including two newly recorded species, Exorista (Adenia) cuneata Herting and Exorista (Spixomyia) lepis Chao. Exorista cantans Mesnil is transferred to the subgenus Podotachina from Spixomyia.     

Taxonomic review of Hemistola Warren, 1893 from China,with descriptions of seven new species (Lepidoptera: Geometridae,Geometrinae)

The genus Hemistola Warren from China is reviewed, and seven new species are described: H. viridimargo, sp. nov., H. glauca sp. nov., H. asymmetra sp. nov., H. arcilinea sp. nov., H. flavifimbria sp. nov., H. orbiculosoides sp. nov. and H. stueningi sp. nov. Two species, acyra and christinaria, are transferred from Hemistola to Maxates and Comostola, respectively: Maxates acyra comb. nov. and Comostola christinaria comb. nov. Including the 25 species previously known from China, a total of 32 species is now recorded. All Chinese species are redescribed. Generic characters based on all species are summarized. Illustrations of adults and genitalia are presented.     

The turtles of the Purbeck Limestone Group of Dorset, southern England

The turtles from the Purbeck Limestone are revised and it is concluded that there are four shell‐based cryptodire species present, namely Pleurosternon bullockii, ‘Glyptops’typocardium comb. nov., Helochelydra anglica comb. nov.,Hylaeochelys latiscutata. There is also one skull‐based species, Dorsetochelys delairi, which may prove to be the skull of ‘Glyptops’, Hylaeochelys or an unknown shell‐type. All other taxa are junior synonyms except ‘Chelone’obovata Owen, 1842 and Tretosternon punctatum Owen, 1842 which are nomina dubia, the material being unfigured and either lost or incorrectly associated. Other taxonomic conclusions are that (1) because Tretosternon is a nomen dubium, the next senior name for this Purbeck–Wealden genus is Helochelydra Nopcsa, 1928; (2) ‘Pleurosternon’typocardium and ‘Glyptops’ruetimeyeri are synonymous, the senior combination being ‘Glyptops’typocardium; (3) the Purbeck ‘Tretosternon’ material is combined with the holotype and only specimen of Platychelys? anglica as Helochelydra anglica comb. nov.; (4) Hylaeochelys emarginata and H. sollasi are junior synonyms of Hylaeochelys latiscutata; (5) one of Owen's ‘lost’ syntypes of ‘Tretosternon punctatum’ has been recognised and is a plastron of Hylaeochelys latiscutata.     

New species and records of the subgenus <Emphasis Type="Italic">Microchelonus</Emphasis> Szépligeti (Braconidae: Cheloninae) from China

The Chinese species of the subgenus Microchelonus Szépligeti of the genus Chelonus Panzer with the female carapace having an incised apex in dorsal view and/or in posterior view are revised. Two new species, Chelonus (Microchelonus) rhagius sp. n. and Chelonus (Microchelonus) tobiasi sp. n. are described. Chelonus (Microchelonus) elegantulus Tobias and Chelonus (Microchelonus) volgensis Tobias are recorded in China for the first time.     

Phylogeny of Caragana (Fabaceae) based on DNA sequence data from rbcL, trnS–trnG, and ITS

Phylogenetic relationships of 48 species of Caragana (Fabaceae: tribe Hedysareae) and one representative each of Astragalus, Calophaca, Halimodendron, and Hedysarum are estimated from DNA sequences of the rbcL gene, trnS–trnG intron and spacer, and ITS region. At least one representative of all five sections and 12 series within Caragana are included. Analyses yielded strongly supported clades corresponding to sections Caragana, Bracteolatae, and Frutescentes. The species of section Jubatae are distributed among three strongly supported clades, i.e., one with the species of section Bracteolatae, another with two species of section Spinosae, and a third as sister to section Frutescentes. All but the last of these six clades are corroborated by at least one unambiguously traced morphological character. The placement of the other four species of section Spinosae are not well supported and lack unambiguous morphological synapomorphies, and the samples of Calophaca and Halimodendron nest within Caragana with weak support.     

Siteroptes (Siteroptoides) species with Pediculaster-like phoretomorphs (Acari: Tarsonemida: Pygmephoridae) from New Zealand and Polynesia

Abstract

Six species of Siteroptes subgenus Siteroptoides—kneeboni (Wicht), mesembrinae (Canestrini), microsaniae n.sp., morelliae (Rack), muscarius n.sp., and portatus n.sp.—have been found in New Zealand. S. (S.) mesembrinae occurs on Niue Island also, and a further new species, pacificus, is recorded from Tonga. The phoretomorph females of all 7 species, the normal females of 4, the males of 3, and larvae of 2 are described and compared. The similarities and differences between normal and phoretomorph females are particularly noted. Besides kneeboni, 2 species described by Wicht but not occuring in New Zealand—athiasae and flechtmanni— are redescribed from type material and transferred to Siteroptes (Siteroptoides). Keys are given for normal females and Pediculaster-like phoretomorph females of Siteroptoides. Siteroptes mesembrinae subsimilis and S. ignotus altaicus are raised to species status. Diagnostically important measurements are given to help define the variation within and between species and morphs.

Early Palaeogene Louisinidae (Macroscelidea,Mammalia), their relationships and north European diversity

Seventeen species from the Palaeocene and Early Eocene of northern Europe, of which 12 are new, are described belonging to the extinct macroscelidean family Louisinidae, raised here from subfamily rank. These species belong to nine genera, of which five are new. The new genera are Walbeckodon , Berrulestes , Gigarton , Thryptodon , and Prolouisina . The new species are Walbeckodon krumbiegeli , Walbeckodon girardi , Paschatherium levei , Berrulestes phelizoni , Berrulestes pellouini , Berrulestes poirieri , Gigarton meyeri , Gigarton sigogneauae , Gigarton louisi , Thryptodon brailloni , Louisina marci , and Teilhardimys brisswalteri . Prolouisina is erected for ‘Louisina’atavella Russell, 1964. Cladistic analysis was undertaken to understand the relationships within the Louisinidae and between them and the North American family Apheliscidae, in which they had earlier been included as a subfamily. Louisinidae are shown to be sister group to a clade consisting of Apheliscidae plus Amphilemuridae and part of a paraphyletic and polyphyletic Adapisoricidae, all of which are tentatively considered to be stem members of the order Macroscelidea. The most primitive macroscelidid, Chambius, from the Early Eocene of northern Africa is nested within Apheliscidae when postcranial characters were included, but in a majority of cases within the Louisinidae when postcranial characters were excluded. Most species from northern Europe became extinct at the end of the Palaeocene, although the genus Paschatherium survived for much of the Early Eocene and Teilhardimys survived into the earliest Eocene. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 164 , 856–936.     

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.
