A new species of the genusFoetorepus (Callionymidae) from Southern Japan with a revised key to the Japanese species of the genus

A new dragonet,Foetorepus masudai, is described from southern Japan. This is the species that Nakabo (1983) mistakenly identified asFoetorepus delandi. It is characterized by large eye, filamentous 1st dorsal spine in adult males, 1st dorsal fin without an obvious dark mark, a dark spot on upper origin of pectoral fin and a large dark blotch on posterior half of pelvic fin. A revised key to the species ofFoetorepus found in Japan is included.

Two new species belonging to the genus Anisomysis (Crustacea, Mysidacea) and a new record of Anisomysis bipartoculata from the Indian Ocean

This paper deals with three species of the genus Anisomysiscollected from the South West coast of Australia of which A.gracilis and A. robustispina are new to science and A. bipanocularais reported for the first time from the Indian Ocean.     

Broadening the definition of the genus Thalassaphorura Bagnall, 1949 (Collembola,Onychiuridae) with a new aberrant species from China

A new species belonging to the tribe Thalassaphorurini, Thalassaphorura problematica sp. n., is described from Northeast China. The new species is closest to the large genus Thalassaphorura by its simple vesicles in PAO and its furcal rudiment, but it does not fit the definition of the genus by the absence of chaeta d0 on head, the number of chaetae in the distal whorl of tibiotarsi and the labium type. We discuss the relative weakness of these last characters at generic level, which lead us to assign the new species to Thalassaphorura instead of erecting a new genus. The diagnosis of Thalassaphorura is broadened accordingly.     

Description of three new species of Paractenopsyllus genus (Siphonaptera: Leptopsyllinae) from Madagascar

The males of three new and rare species of the Malagasy endemic genus Paractenopsyllus Wagner, 1938 are described. Paractenopsyllus beaucournui, P. oconnori and P. raxworthyi have been collected on endemic small mammals and the black rat. As for others species of the genus, biotopes are rain-forests of the central highlands or the northern mountains of Madagascar. Two of the described species were collected at elevations lower than typical for the genus and below the limits of the highland bioclimatic zone. Morphological affinities between these new species and those already described provide taxonomic framework for the genus. An updated identification key is provided for the diagnosis of all the 20 Malagasy species of Leptopsyllinae.     

Mysidacea (Crustacea) from the Minicoy lagoon (Lakshadweep, India) with description of a new species of Anisomysis

Four species of mysids collected from the Minicoy lagoon are reported. Anisomysis minicoyensis sp. nov. is distinguished from the related species by the shape of the rostrum, the relative length of the antennal scale and the short protuberances on the second segment of the mandibular palp. The other three species recorded are Siriella australiensis, Anisomysis truncata and unidentified species of subfamily Gastrosaccinae.     

Description of a new trypanorhynch species (Cestoda) from Indonesian Borneo, with the suppression of Oncomegoides and the erection of a new genus Hispidorhynchus

A new species of Oncomegas Dollfus, 1929 is described from the cowtail stingray, Pastinachus atrus (Macleay), collected in the Makassar Strait, Indonesian Borneo. Oncomegas trimegacanthus n. sp. possesses 2 oval bothria, gland cells within the bulbs, prebulbar organs, a distinctive basal armature with a single macrohook on the bothrial surface of the asymmetrical basal swelling, and a heteroacanthous, heteromorphous metabasal armature with 10 hooks per principle row. It differs from congeners by its possession of additional enlarged hooks at the base of the tentacle. Because of apparent morphological similarities, we suppress the genus Oncomegoides Beveridge & Campbell, 2005 with Oncomegas, and place the type and only species, Oncomegoides celatus Beveridge & Campbell, 2005 , within Oncomegas as Oncomegas celatus n. comb. Three species of Oncomegas , namely, Oncomegas paulinae Toth, Campbell & Schmidt, 1992, Oncomegas australiensis Toth, Campbell & Schmidt, 1992, and Oncomegas aetobatidis Campbell & Beveridge, 2009, differ from other species, possessing testes posterior to the ovary and a metabasal armature consisting of tiny, relatively homeomorphous hooks, with more than 14 hooks per principle row. Based on these morphological differences, a new genus, Hispidorhynchus n. gen., is erected, with Hispidorhynchus australiensis n. comb. as the type species.     

Two new species of Acervus (Pezizales) with a key to species of the genus

Studies on the genus Acervus from China are reviewed briefly. Six of the seven known species of the genus are currently recorded in this country. Acervus beijingense and A. changchunense are described as new based on morphological features and molecular data, and A. flavidus with minor emendation is added to the Chinese fungus flora. Phylogenetic relationships among four of the seven species of the genus are investigated based on the 28S rDNA sequence analysis. Species of the genus formed a single clade with high bootstrap support. The sequences of A. epispartius forma epispartius and that of A. flavidus obtained from materials in different geographical regions together formed a group with 100% bootstrap support. Ascospore size and shape are important criteria in the taxonomy of the genus and are phylogenetically informative. A dichotomous key to all described species of the genus is provided.     

Description of a new species of the genus Tribasodites Jeannel (Coleoptera, Staphylinidae, Pselaphinae) from East China with a key to world species

A remarkable new species of the genus Tribasodites, 1960, Tribasodites spinacaritussp. n. is described and illustrated from Zhejiang Province, East China. A key to world species of the genus is provided. Systematic position of the new taxon is discussed.     

A new species of Kanahia (Asclepidiaceae) with a reconsideration of the genus

A new species, K. carlsbergiana , is described in what is currently considered a monotypic genus. The new species is only known from permanent streams in the Arssi and Bale regions of S Ethiopia. The delimitation and position of the genus is reconsidered in light of the additional information provided by the new species. The distinctiveness of the genus is reconfirmed whilst no new clues to possible relationships with other genera were observed. The taxonomy of the other species, K. laniflora (Forssk.) R. Br., is also briefly reconsidered.     

A synopsis of the genus Mysidopsis (Mysidacea, Crustacea) with a key for the identification of its known species and descriptions of two new species from South African waters

A list of the species now included in the genus is given with notes of their geographical distribution and (where possible) details of their ecology and a key for their identification. An amended diagnosis of the genus is given to include two new species, hitherto unnamed and known only from damaged and inadequate material, which are now named and fully described and figured.     

Taxonomic studies on genus Tetramorium Mayr (Hymenoptera, Formicidae) with report of two new species and three new records including a tramp species from India with a revised key

Two new species of Tetramorium Mayr, namely Tetramorium shivalikensesp. n. and Tetramorium triangulatumsp. n. are described. Tetramorium triangulatumsp. n. belongs to the inglebyi-species group and is described based on worker, queen and male caste, while Tetramorium shivalikensesp. n. belongs to the ciliatum-species group and is described based on worker caste only. Three species viz., Tetramorium caldarium (Roger), Tetramorium tonganum Mayr and Tetramorium urbanii Bolton represent first records from India. The male caste is described for the first time in the case of Tetramorium tonganum. Among these, Tetramorium caldarium is a tramp species which extends its limit to India as well. A revised key to the Indian ants of this genus is also provided herewith.     

A new genus and a new species of Siricinae (Insecta, Hymenoptera, Siricidae) from India with a revised key to its world genera

Neoxeris gen.n. (type species: Neoxeris melanocephala sp.n.) from India is described and illustrated. Neoxeris is related to Sirex Linnaeus and Xeris Costa from which it is distinguished. A revised key to the world genera of Siricinae is provided.

Morphogeographic variations in the genusMesopodopsis Czerniavsky with descriptions of three new species (Crustacea,Mysidacea)

Most of the exceptional morphological features of the genusMesopodopsis are shared withNanomysis, Diamysis, andLimnomysis in a mosaic-like pattern. This group, comprising euryhaline species from fresh-to metahaline waters, has its centre of recent species richness in the Mediterranean to Ponto-Caspian region. Within the genus one may distinguish two morphogeographic groups, Euro-African species with a spine below the statocyst, and Indo-Australasian species without this spine. Detailed study from the entire distribution range indicates thatM. slabberi (van Beneden) should be split into 4 species: the nominal form from the NE-Atlantic, Mediterranean, and Black Sea, with 5–8 segments on the tarsus of the fourth thoracic endopod;M. aegyptia n.sp., widely distributed in the Mediterranean, with 7–9 segments on this tarsus as well as dimorphic setation patterns on the eighth tarsus;M. tropicalis n.sp. from equatorial W-Africa with 5–6 segments and dimorphic setation patterns on the mandibular palp; andM. wooldridgei n.sp. from South African waters with 9–12 segments on the tarsal joint of the fourth thoracic appendage, respectively. A key to the seven known species of the genus is given.
