拟红眼蝉属的订正(同翅目:蝉科)

REVISION OF THE GENUS PARATALAINGA HE (HOMOPTERA: CICADIDAE)

作者之一姚渭,1981年在其硕士研究生学位论文《中国蝉科分类的初步研究》89—92页(图50,图版XV:6-9)记载有新属周氏蝉属Chouia Yao,以纪念导师周尧教授,并记述了3新种,1新组合种,论文散发50余册,但未正式发表。 贺锦川1984年以同一类群建立拟红眼蝉属Paratalainga He,记述有2新种:P.reticulata He(=C.pulchra Yao),P.fusipenis He(=C.liuzhiensis Yao).论文正式发表在上海《昆虫学研究集刊》上,因此贺的属名和种名是有效的。

The genus Paratalainga was established by He Jin-chuan in 1984, based on the type species P. reticulata He and P. fucipennis He. However, the description was based only on a male from Guangxi and a female from Hainan, China. He did not list the male genitalic characters of the genus, and some characters given related to individual characters, not characters relevant to the genus. It is obvious that the simple description of outer morphological characters can no longer meet the need to differentiate Paratalainga from related genera. Following examination of the type specimens and additional specimens from provinces Yunnan, Guizhou, Sichuan and Hunan, especially of male genitalia. characters of the genus have been reassessed in the present research and three new species and a new combination are given. So far, 6 species haee been found all distributed within the Oriental region. Type specimens are deposited in the Entomological Museum of the Northwestern Agricultural University, Yangling, Shaanxi, China.Generic Characters: Male genitalia showing distinct asymmetry, the letf being more developed than the right; uncus rather slender, the base with a ball-shaped projection, theca tube-shaped; tympanal coverings small and lateral; tympanal orifices exposed; tegmina opaque, nodal lines distinct and the venation densely reticulate; wings opaque, the claval areas wide.Type species: Paratalainga reticulata He.Distribution: Oriental Region.This genus is similar to Talainga Distant, 1890, but differs from the latter as follows: (1) male genitalia distinctly asymmetrical, the left more developmed than the right; (2) tegmina with venation densely reticulate.Key to Species of the Genus Paratalainga1.
