A REVIEW OF THE GENUS ACRICOTOPUS KIEFFER (DIPTERA: CHIRONOMIDAE) IN CHINA

Abstract The genus Acricotopus Kieffer including three species from China is reviewed. Acricotopus lucens (Zetterstedt) is reexamined. Two species A. simplex sp. nov. and A. zhalingensis sp. nov. are described as male imagines. Acricotopus simplex sp. nov. was collected from Xizang, Sichuan and Qinghai Provinces; the species differs from others of the genus by the absence of hind tibial comb, temporal and clypeal seta. Acricotopus zhalingensis sp. nov. was collected from Qinghai Province; the species is recognized by a combination of characters: the larger body size; the clypeus without setae; anal lobe strongly produced, nearly hemispherical shape; inferior volsella triangular, strongly sclerotized; gonostylus with 13 very long setae. A key to the world males of the genus is presented. The generic diagnosis is emended. All the types described in this paper are deposited in Department of Biology, Nankai University, China (BDN).

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.     

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.
