Comments are presented on four East-Asian species of the genus Chilocoris Mayr, of which three are known but have been hardly mentioned―namely C. alienus Horváth, C. birmanus Lis and C. nitidulus Lis. One new species is described here as C. monticola n. sp. New distribution records are provided: C. alienus is new to China (Liaoning), as well as newly representing the genus in northern China; C. birmanus is new to Taiwan; and C. nitidulus is new to Vietnam and Thailand. Until recently, C. monticola n. sp. found in Japan has been misidentified as C. nitidus Mayr, and earlier records of the latter from Japan are really this new species. Male genital structures are described and illustrated for all four species, and additionally female genital structures are also described for C. birmanus and C. monticola. These East-Asian species are significantly similar to each other in important morphological structures such as the pronotal punctuation, extension of evaporatorium, and the male and female genital organs, yet they can be distinguished from many other congeners by these same structures. It seems plausible, therefore, to group these four species in a species-group named “nitidus-group” because of the species’ definite association with C. nitidus. This species-group possibly consists at least ten East-Asian and one North American species and exhibits a relictual, trans-Beringian disjunction, suggesting an association of this group with the Tertiary circum-boreal flora. Its distributional pattern may further differentiate the species-group from other congeners.

A New Species

Taxonomy of the two previously described species of the hippolytid shrimp genus Heptacarpus Holmes, 1900, H. camtschaticus (Stimpson, 1860) and H. geniculatus (Stimpson, 1860), are reassessed. It has been found that Eualus geniculata longirostris Kobjakova, 1936, which has been regarded as a junior synonym of Heptacarpus geniculatus, is a valid taxon, herein reinstated as a full species. It has been found that two species were confounded in previous literature under the name H. camtschaticus, and one of them is described as new, H. acuticarinatus n. sp. Three species, H. camtschaticus, H. geniculatus and H. longirostris, are redescribed. These four species all belong to an informal species group characterized by the lack of pereopodal epipods. Differences in morphology and distributional pattern among the four species are discussed. A key in aid of the identification of the Asian species belonging to the species group is provided.

First Time

This study revises the caddisfly genus Rhyacophila Stephens, Rhyacophilidae, for Yakushima Island within the northern Ryukyu Archipelago in southwestern Japan. Four new species are described based on adults: Rhyacophila yakushima sp. nov. of the R. anatina Species Group, R. arakawa sp. nov. of the R. lieftincki Species Group, R. miyanoura sp. nov. of the R. yosiiana Species Group, and R. nagata sp. nov. of the R. ulmeri Species Group. Additionally, two species are recorded for the island for the first time: R. brevicephala Iwata 1927, a Japanese species, and R. shikotsuensis Iwata 1927, an East Asian species.

AbstractThe fujiyamai species group is formed for two East Asian species of the genus Plagiophorus Motschulsky, P. fujiyamai (Kubota) from Japan, South Korea, and China (Beijing) and P. subcorticarissp. nov. from Taiwan. The fujiyamai group is unique in that the antennal club is not excavated in the male and antennomere III has two distinct sutures. A key to the species of the fujiyamai group is given.

Eleven Species

Sixteen species of Uropodina were found in samples of soil mites from Vietnam, in the Institute of Soil Biology of the Biology Centre AS CR (Èesk Budìjovice, Czech Republic) and the Soil Zoology Collections of the Hungarian Natural History Museum (Budapest, Hungary). Five of them are known species — Angulobaloghia vietnamensis (Kontschán, 2008), Metagynella vietnamensis Hiramatsu, 1981, Uroobovella similitakensis Hirschmann, 1981, Uroobovella topali Hirschmann, 1981, and Uropoda hirschmanni Hiramatsu, 1977. Eleven species are described as new — Trachytes vietnamensis sp. nov., Dinychus serratus sp. nov., Trichouropoda aspera sp. nov., Uroobovella oviformis sp. nov., Uroobovella multisetosa sp. nov., Paradinychus pilosus sp. nov., Phymatodiscus kuni sp. nov., Uropoda setata sp. nov., Uropoda lichenicola sp. nov., Angulobaloghia scrobia sp. nov. and Depressorotunda (Depressorotunda) alveolata sp. nov. The genus Paradinychus is resurrected and three species are moved into this genus, as P. sumatrensis (Vitzthum, 1921) comb. nov. and P. fistulata (Hiramatsu, 1982) comb. nov. Keys to the species of the genus Paradinychus, to the Asian species of Trachytes and to the Uropoda spiculata species group are given.

An analysis of the mtCOI sequences in the species from the genus Ypsolopha Latreille, 1796 made it possible to confirm a new species for science, Y. occultatella sp. n., morphologically similar to the East Asian species Y. yasudai Moriuti, 1964. The genetic distance between the mtCOI sequences in Y. occultatella sp. n. and Y. yasudai is 0,066–0,069 (6,6–6,9 %). However, the minimal genetic distance, 0,038–0,042 (3,8–4,2 %), was determined between the mtCOI sequences of the new species and Y. blandella (Christoph, 1882), while these species differ well in the forewing pattern.

First Time

The Australian Mycodrosophila fauna comprises 21 species distributed in northern and eastern Australia to southern New South Wales. Only one species, M. argentifrons Malloch, is previously described from Australia; the south-east Asian species M. separata (de Meijere) is recorded for the first time. The remaining 19 species are new: adequate material has been available to permit the description and naming of 18 of them.
