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.     

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.     

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.     

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.     

Three new genera of Leptophlebiidae (Ephemeroptera) from New Zealand

Abstract

Three new genera—Austroclima, Mauiulus, and Cryophlebia—are established for species of Leptophlebiidae from New Zealand. The following new combinations are included: Austroclima sepia (Phillips) and Cryophlebia aucklandensis (Peters). Atalophlebioides sepia is redescribed as Austroclima sepia and a neotype is designated. Two new species, Austroclima jollyae and Mauiulus luma, are described. All life stages are described, and the relationships of each genus are discussed. Keys are given to male and female imagos, subimagos, and nymphs of each species, and to all New Zealand genera with species previously placed in Atalophlebioides.     

The geographic distribution of flavone-glycosylating genes in Silene pratensis (Rafn.) Godron and Gren. (Caryophyllaceae)

In Silene pratensis three loci (g, gl and fg) control the glycosylation of isovitexin. Three alleles are known for both the g-locus (g, g ^G and g ^X ) and the gl-locus (gl, gl ^A and gl ^R ); for the fg-locus there are only two alleles (fg and Fg). The distribution of these alleles over 285 European populations of S. pratensis has been investigated. It was concluded that there are three different chemical races within S. pratensis in Europe. The first race contains the populations in western and southern Europe and displays high frequencies of g ^G , gl and fg. The frequencies of g ^G and gl ^R are very high in the second chemical race, which can be found in the USSR, Scandinavia and eastern Poland. The third chemical race occurs in central Europe and in this race the frequencies of both g and gl ^R are high, Fg has low to moderate frequencies in the second and third groups. The alleles gl ^A and g ^X are seldom found in S. pratensis, but are present in the closely related S. dioica. They do occur with low frequencies in some populations of S. pratensis, possibly as a result of hybridization with S. dioica.     

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.

Revision and phylogeny of the European species of the Eurytoma morio species group (Hymenoptera: Eurytomidae), parasitoids of bark and wood boring beetles

A revision of Eurytoma (Hymenoptera, Eurytomidae) species belonging to the morio group is proposed. Species discrimination is based on morphological and, partly, on molecular data, including the barcoding fragment of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the D2 expansion region of the 28S ribosomal gene. Morphological and molecular phylogenetic analyses largely support the morphological evidence. E urytoma cristata Delvare sp. nov. , E urytoma saliphila Delvare sp. nov. , and E urytoma sylviae Delvare sp. nov. are described from France, E urytoma ithma Delvare sp. nov. is described from France and Italy, and E urytoma gatesi Delvare sp. nov. is described from North America and France. Decatomidea polygraphi Ashmead, 1894 and Ipideurytoma spessivtsevi Bou?ek & Novicky, 1954 are synonymized with Eurytoma afra Boheman, 1836. Eurytoma auricoma Mayr, 1878 is removed from synonymy with Eurytoma arctica Thomson, 1875 and is synonymized with Eurytoma maura Boheman, 1836. Eurytoma eccoptogastri Ratzeburg, 1844, Eurytoma flavoscapularis Ratzeburg, 1844, Eurytoma flavovaria Ratzeburg, 1844, and Eurytoma masii var. flavonigra Russo, 1938 are synonymized with Eurytoma morio Boheman, 1836. Eurytoma masii Russo, 1925 and Eurytoma kemalpasensis Narendran, Tezcan & Civelek, 1995 are synonymized with Eurytoma striolata Ratzeburg, 1848. Eurytoma melanoneura Walker, 1871 and E. masii are removed from synonymy with E. morio. Lectotypes are designated for E. afra, E. auricoma, E. masii, Decatoma aloisifilippoi Russo, 1938, and E. masii var. flavonigra. © 2014 The Linnean Society of London     

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.     

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.
