摘要
等啮属(Isophanes)为单啮科(Caeciliidae)的一个小属,由Banks(1937)根据台湾的标本建立的,模式种Isophanes decipiensBanks,同时他把Psocus palliatus Hagen移入本属,Badonnel(1955)和Smithers(1956)分别记述了非洲安哥拉的Isophanes angolensis和南非的Lcapeneri两个种,直到现在,近40年尚末增加新的种类,仅此4种。
Four new species of Isophaes Banks from China are described and figured in the present paper. The type specimens are kept in the Insect Collection of Beijing Agricultural University. Isophanes sinensis sp nov. (fig.1) Holotype ♂, paratypes 2♂♂, 1♀, Hangzhou C. (City), Zhejiang Prov. 1957-Ⅶ-5. This new species is close to Isophanes decipiens Banks from Taiwan, but is different from it, in pterostigma with strongly hind angle and broader at apex. Isophanes oxyostigma sp. nov. (fig.2) Holotype ♂, Guiyang C. Guizhou Prov. (1000 m), 1988-ⅴ-24. This new species in the pterostigma apparence is similar to Isophanes angolensis Badonnel, but differs from the latter in Cula and M forked higher and body smaller in size (length of body 2.79mm, to tip of folded wings) Isophanes cyclostigma sp. nov. (fig.3) Holotype ♂, Pingxiang C. Guangxi prov. 1963-ⅴ-9. This new species closely related to Isophanes capeneri Smithers but differs from the latter by basic Rs ad M nearly form a straight line, pterostigma hind angle rounded and body colour not darken than that species. Isophanes yangi sp. nov. (fig.4) Holotype ♀, paratype 1♀, Pingxiang C. Guangxi prov. 1963-Ⅴ-6. This new species in venation special differs from the all species of the Isophanes. The subgenital plate sclerozation somewhat resembles the Isophanes angolennsis Badonnel, but easiy saparated it by the Rs and M are joined by a crossvein and Cula cell higher.
