The Rheocricotopus (Psilocricotopus) chalybeatus species group from China is reviewed. Three new species, R. (P.) brochus
sp. n., R. (P.) rotundus
sp. n. and R. (P.) serratus
sp. n. are described as adult males. R. (P.) imperfectus Makarchenko & Makarchenko, 2005, R. (P.) robacki (Beck & Beck, 1964) and R. (P.) valgus Chaudhuri & Sinharay, 1983 are recorded from China for the first time and annotated. The diagnosis for the species group is emended and a key to adult males of the species group in China is presented. 相似文献

Two new species of chironomid midges (Rheosmittia arcuata n.sp. and Mesocricotopus loticus n.sp.) are recognized. They may easily be missed in collections due to their small size, and difficulty in collecting from the larval microhabitat (sand substrates for R. arcuata n.sp., low order streams with depositional substrates including gravel, sand, and silt for M. loticus n.sp.). Some morphological features are given to distinguish the new species from similar congeneric forms. The distribution and some ecological information for each species are also briefly discussed. 相似文献

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. 相似文献

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. 相似文献

Hanocladius longipes gen. nov., sp. nov. from Oriental China is described from the male imago. The long metatarsus, the very broad, scale-like virga and the conspicuously scalpellate acrostichals distinguish the genus from all of the known genera in Orthocladiinae. 相似文献

The first records of the Tanytarsini genera Stempellina and Zavrelia in the Oriental Region based on adult males are presented. Two species, Stempellina clavata sp. n. and Zavrelia clinovolsella sp. n. from southern China, are described, and the generic diagnoses of the two genera are emended to accommodate the new species. A key to the male imagines of the genus Zavrelia is given. 相似文献
