Two new species of the orientalis group of Rheocricotopus (Psilocricotopus) from China (Diptera: Chironomidae)

Rheocricotopus (Psilocricotopus) calviculus sp. n. and R. (P.) villiculus sp. n. from China are described as male imagines. The species are closely related to the previously described R. (P.) orientalis Wang forming a new group, the orientalis group, which eventually may deserve the rank of subgenus or even genus. The group is distinguished by lacking a humeral pit, numerous sensilla clavata on third palpomere, cuneiform wings, no or few setae on squama, long legs, banded abdomen, very long inferior volsella, gonocoxite with apical extensions, and gonostylus with a median triangular projection.     

A new species of the genus <Emphasis Type="Italic">Stempellinella</Emphasis> (Diptera: Chironomidae) from Hiroshima,Japan

Stempellinella coronata sp. n. is described and illustrated based on male imagines. The new species can be separated from other Stempellinella species by its small size, low antennal ratio, high front leg ratio, minute frontal tubercles, a comparatively long median volsella, lacking median tergal setae, and lacking well-developed anal crests on the tergite IX. The generic diagnosis of Stempellinella is emended mainly to accommodate S. coronata. The species has so far been collected only from autumn to winter at pools in the unpolluted upper to mid reaches and was recorded first from the Ohta River system, Hiroshima, Japan.

记述采自中国浙江古田山倒毛摇蚊属1新种:短小倒毛摇蚊Microtendipes brevissimus sp.nov.。对其特征作了描述,绘制了雄成虫的特征图。新种的主要鉴别特征为:肛尖短小,无中附器,生殖节的第9背板中部无刚毛。     

New species of Oukuriella (Diptera: Chironomidae) from Costa Rica

The males of three new species of Oukuriella Epler are described from Costa Rica. The genus had been previously recorded only from South America. Oukuriella annamae sp. nov. has genitalia similar to O. albistyla Epler, but differs in having transverse bands on abdominal segments In, IV, VI and VII, a lower AR, no humeral setae and fewer dorsocentral setae. Oukuriella costaricense sp. nov. differs from other described species in the genus by its brown abdomen, unnotched posterior margin of tergite IX and distinctive superior volsella, with its sharply bent, thin upper arm directed medially, and digitus small and directed caudad. Oukuriella rushi sp. nov. has apices of femora tipped with brown, a brown abdomen and distinctive superior volsella, with upper arm shorter and broader, and digitus longer then O. costaricense. The female of Oukuriella costaricense is also described. This is the first female described for the genus. Based on male and female genitalia, Oukuriella is closely related to Epedilum Townes and Zavreliella Kieffer. A key is provided to separate the males of the six described species.

Two new species of Stenochironomus Kieffer (Diptera,Chironomidae) from Zhejiang,China

Two new species of Stenochironomus Kieffer (Diptera: Chironomidae: Chironominae), Stenochironomus brevissimus sp. n. and Stenochironomus linanensis sp. n., are described from China and the male imagines are illustrated. Stenochironomus brevissimus sp. n. can be separated from the so far known species by having very short and small, spatulate superior volsella with two long setae, whereas Stenochironomus linanensis sp. n. is easily separated from the other species of Stenochironomus by the following characters: wings transparent, body yellow, superior volsella finger-like, with nine long setae, elongated inferior volsella with four long setae and one well developed terminal spine; tergite IX with 10−15 long setae medially. A key to the males of Stenochironomus occurring in China is given.     

Philopotaminae of Madagascar (Trichoptera: Philopotamidae)

The Malagasy fauna includes two genera of Philopotaminae: Wormaldia McLachlan 1865 and an endemic new genus, Ranarijaodes n. gen. The Malagasy and African (sensu stricto) lineages of Wormaldia are distinct. Apomorphic characters (the shape of the phallic apparatus for the African species and the splitting of the median lobe of the tenth tergite for the Malagasy species) confirm their separation. New captures are reported for two of the four previously known species of Wormaldia. Seven new species are described: Wormaldia ambahibeae n. sp., W. faharoa n. sp., W. fahatelo n. sp., W. randriamasimananai n. sp., W. fahefatra n. sp., W. legrandi n. sp. and W. fahadimy n. sp. Ranarijaodes n. gen. is close to Dolophilodes Ulmer 1909. It is described for the three new species Ranarijaodes fiana n. sp., R. angapi n. sp. and R. atsimo n. sp. The 14 Malagasy species of Philopotaminae are endemics of the island. Their geographical distributions and ecological preferences are described and discussed.     

New Genera and Species of ‘Giant’ Ostracods (Crustacea: Cyprididae) from Australia

Two new genera of giant ostracods Lacrimicypris n. gen. and Repandocypris n. gen. from Australia are described and eight new species:L. kumbar n. sp., R. austinensis n. sp., R. gleneagles n. sp., Mytilocypris coolcalalaya n. sp., Australocypris bennetti n. sp., A. beaumonti n. sp., A. mongerensis n. sp. and Caboncypris kondininensis n. sp. The number of known Australian genera and species of giant ostracods are now 6 and 21, respectively. Keys to genera and species are provided: all species can be distinguished using the hemipenis and male first leg. The usefulness of the bursa copulatrix as a species-level taxonomic character is highlighted. Most of the species described in this paper occur in salt lakes and existing ecological information on Western Australian species, as well as the distributions of all species, are summarized. Western Australia has a particularly rich halobiont fauna but current explanations relating richness of the halobiont fauna to the widespread occurrence of salt lakes appear incomplete. Australocypris bennetti is unusual in that it is frequently found at pH < 4. Its morphology differs slightly in acidic and alkaline waters.     

A new species of <Emphasis Type="Italic">Pseudomaseus</Emphasis> (Coleoptera: Carabidae: Pterostichini) from Greece

A new species of carabid beetles, Pterostichus hejkali sp. n. is described from Northwest Greece (type locality: Epirus District, Ioannina Prefecture, Ioannina Lake environs). Diagnostic characters include distinctive shape of the median lobe of aedeagus, of right paramere and of sexual modification on last visible sternum in males as well as shape of pronotum and size of body. Members of the new species are most similar to P. minor. A key to the identification of the Balkan taxa of Pseudomaseus is presented.     

The Genus Prosopistoma from China,with Descriptions of Two New Species (Ephemeroptera: Prosopistomatidae)

Two mayfly species Prosopistoma trispinum sp.n. and P. unicolor sp.n. collected from southwestern China are described as new to science, their main diagnostic larval characters are illustrated. The larvae of P. trispinum sp. n. can be differentiated by the large number of mandibular bristles, fewer spines on the inner margins of fore tibiae and mesonotal color pattern. The larva of P. unicolor sp. n. can be distinguished by its uniform reddish brown mesothoracic carapace which has no median ridge, and by more tiny serrated foretibial bristles. New distributional records for P. annamense Soldán et Braasch in China are first provided. The habitats of Chinese Prosopistomatidae show they can live in lotic water from stream to large river.     

Report on the Polycystididae (Rhabdocoela, Kalyptorhynchia) from Australia, with the Description of Twelve New Species and Six New Genera

Twelve new species of Polycystididae Graff, 1905 are described from the Australian east coast. Nine of them could not be placed in any of the existing genera, and therefore six new genera are erected. Alchoides n. gen. differs from all other polycystidid genera by the presence of a bundle of glands that opens into the distal part of the male atrium (accessory vesicle type V). Two species are included in the genus, A. alchoides n. sp. and A. dittmannae n. sp., which differ from each other in the shape of the stylet. Ametochus gehrkei n. gen n. sp. can be distinguished from other polycystidids by the presence of a prostate vesicle type III associated with a prostate stylet type III, combined with the presence of an accessory stylet type III, while a prostate stylet type II is lacking. Typical for Arrawarria inexpectata n. gen n. sp. is the combined presence of an armed cirrus with a prostate vesicle type II connected to a prostate stylet type II. Two species are assigned to the new genus Duplexostylus n. gen.: D. rowei n. sp. and D. winsori n. sp. These two species have two unique features: a prostate vesicle type IV directly connected to a prostate stylet type III and an asymmetrical septum that surrounds the proximal part of the male atrium. They can be distinguished from each other by differences in the detailed construction of their stylets. Two new species are placed in the new genus Stradorhynchus n. gen.: S. caecus n. sp. and S. terminalis n. sp. They have unpaired gonads and a prostate vesicle type IV connected to a prostate stylet type IV, which combination of characters makes them unique within the Polycystididae. The two species differ from each other in the shape and size of the stylet. Triaustrorhynchus armatus n. gen., n. sp. is the first species of the Polycystididae to have three types of stylet in the male atrium: a prostate stylet type II, a prostate stylet type III and an accessory stylet type III. Three new species could be placed in existing genera: Cincturorhynchus monaculeus n. sp., Paraustrorhynchus caligatus n. sp. and Polycystis australis n. sp. All three differ from their congeners in the form and dimensions of their stylets. All newly described species are discussed, giving their similarities and differences with resembling species. Austrorhynchus hawaiiensis Karling, 1977 is reported for the first time in Australia, and the Australian population is compared with populations from other regions. The presence of Gyratrix hermaphroditus Ehrenberg, 1831, one new species of Paulodora Marcus, 1948 and a new genus of Typhlopolycystidinae Evdonin, 1977 is mentioned.     

Preliminary study of the development of the subfossil chironomid fauna (Diptera) of Lake Taylor,South Island,New Zealand,during the younger Holocene

The composition and succession of the subfossil chironomid fauna has been studied in a sediment core from Lake Taylor. The sediments of the core are all within the Nothofagus phase of the last 3000 years within the Aranuian. In the older sediments of the core the chironomid fauna was dominated by Tanytarsini and Orthocladiinae whereas Chironomini dominated in the more recent sediments. The species diversity is very high compared with the results of other studies of the recent chironomid fauna of lakes in the South Island. The most abundant head capsules belong to the taxa Chironomus zealandicus, Tanytarsus vespertinus, Corynocera sp., and Eukiefferiella sp. Several additional taxa which have not yet been described also occurred in large numbers. It is not possible to correlate any definite changes in the composition of the subfossil chironomid fauna with a change in climatic conditions or the trophic status of the lake.     

Two New Lacconectus Species from Vietnam (Coleoptera; Dytiscidae)

Two new species of Lacconectus Motschulsky are described from Vietnam, Lacconectus valeriae sp. n. and L. baolocensis sp. n., and a key is given for the species described from and occurring in that country. Together with the two new species, seven species are now known from Vietnam, and the number of Lacconectus species rises to 60.     

New representatives of the genus <Emphasis Type="Italic">Nahublattella</Emphasis> Bruijning, 1959 (Dictyoptera,Blattellidae) from Central and South America

The following nine new species of the genus Nahublattella Bruijning, 1959 are described from Ecuador and Mexico: N. cuyabeno sp. n., N. alexandri sp. n., N. incurvata sp. n., N. maya sp. n., N. plena sp. n., N. bispina sp. n., N. ultima sp. n., N. beikoi sp. n., and N. reticulata sp. n. The structure of the male genitalia of the new species is described in detail. The genus diagnosis is discussed.     

Two new species of the genus Chablisea Gauld et Dubois (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam

Two new species of the genus Chablisea Gauld et Dubois, 2006 are described from Vietnam based on ichneumonid material collected from 2002 to 2008. Chablisea condimenta sp. n. differs from other species of the genus by the absence of the second abscissa of hind wing vein Cu1, narrower hind femur (5.2 times as long as wide), and yellow subapical, lateral spots on metasomal tergites 2–5. Chablisea khuatdanglongi sp. n. is characterized by its face as high as wide, yellow with a median black stripe extending to a black transverse band at the base of the clypeus. One species, C. albifacialis (Kusigemati, 1984) is a new combination.     

New Podonominae from Japan,Boreochlus longicoxalsetosus sp. n. (Diptera: Chironomidae) with a Key to Species of the Genus

During the survey of chiromonid midges from Kyushu, the authors found a new species of Podonominae (Chironomidae), Boreochlus longicoxalsetosus. The male imago of this new species is described and illustrated. This constitutes the third record of the subfamily Podonominae, and the second species of the genus from Japan. The new species has very long notable setae lying on the dorsomedial surface distal to the volsella, which are never seen in the other Boreochlus species. A key to species of the genus in the world is given.     

Two new chironomid species (Diptera,Chironomidae) from Wrangel Island

Two new species from Wrangel Island, Orthocladius (Eudactylocladius) tschernovi sp. n. and O. (E.) ushakovskiensis sp. n. (Orthocladiinae), are described and illustrated from on the male adults. Orthocladius (E.) tschernovi sp. n. is closely related to O. (E.) fuscimanus (Kieffer) and O. (E.) musester Sæther, but can be distinguished from both by an almost straight transverse sternapodema, a rounded triangular superior volsella, and a long phallapodema, as well as by the presence of a subapical crista dorsalis of the gonostylus and by the shape of the anal point. Orthocladius (E.) ushakovskiensis sp. n. differs from all the known species of the subgenus in the absence of superior and inferior volsellae and in the shape of both short gonostylus and the short and wide anal point.     

Species Diversity of Japanese Clusiidae (Diptera: Acalyptrata) with description of 12 new species

The Japanese Clusiidae are revised and 23 species, including 12 species new to science, are recognized and keyed. Clusiodes angulosus n. sp., Clusiodes discostylus n. sp., Clusiodes tobi n. sp., Clusiodes usikumuri n. sp., Craspedochaeta varicolor n. sp., Heteromeringia crenulata n. sp., Heteromeringia quadrispinosa n. sp., Heteromeringia sexramifera n. sp., Heteromeringia yamata n. sp., Phylloclusia quadrivittata n. sp., Sobarocephala uncinata n. sp., and Tetrameringia borealis n. sp. were described as new. Distribution records were compiled and mapped. Transitional climatic zone between the warm and cool temperate zones is possibly suggested as one of the most richest temperate area in terms of Japanese clusiid species richness. Hendelia beckeri Czerny 1903, Paraclusia japonica Sasakawa 1957, and Clusiodes plumosus Sasakawa 1964 are broadly distributed over all the Japanese temperate forests, but these are not always most abundant species. The clusiid assemblage was heterogeneous in the species composition among various forest types. The femalebiased sample caught by Malaise traps and distinction of clusiid species composition between temperate and subtropical zones are also pointed out.
