REVISION OF THE GENUS JERMAKIA JAKOVLEV(HYMENOPTERA:TENTH-REDINOMORPHA:TENTHREDINIDAE)

TAXONOMIC STUDY ON THE GENUS CASIPTERYX TAEGER (HYMENOPTERA:TENTHREDINOMORPHA)

本文厘定了叶蜂科壮并叶蜂属ＪｅｒｍａｋｉａＪａｋｏｖｌｅｖ。壮并叶蜂属仅分布于东亚地区，已知３种，中国均有分布。本文记述５种，其中包括２新种：光背壮并叶蜂Ｊ．ｇｌａｂｒａｔａｓｐ．ｎｏｖ．，云南壮并叶蜂Ｊ．ｙｕｎｎａｎｉｃａｓｐ．ｎｏｖ．。文中简要描述了中华壮并叶蜂ＪｅｒｍａｋｉａｓｉｎｅｎｓｉｓＭａｌａｉｓｅ的雄性，并编制了壮并叶蜂属已知种检索表。

The genus Casipteryx Taeger is revised with description of the male of the type species and a new species: Casipteryx stigma, sp. nov. The new species differs from the type species in the following: head dilated behind eyes, inner orbit not obviously protrudent in dorsal view; anterior margin of clypeus without acute dent, lateral lobe wide and obtuse, anterior margin of labrum emarginated; third tergite of antenna longer than following two tergites together; body hairs shorter than diameter of an ocellus; stigma of fore wing wide and short, truncate at apex; length of cell 2M nearly as long as breadth; thorn of mesosternum obtuse; punctures on mesopleuron shallow with linear shining interspace; apex of sheath rounded; penis valve narrow without apical lobe; serrulae protrudent, SF=12/0. The male of C. roborowskyi (Jakovlev) is quite similar to female of the species except that head behind eyes strongly narrowing and the second tergite laterally with a brownish spot. A key is provided for the two known species of Casipteryx Taeger. Type materials are deposited in Insect Collection of Central South Forestry University.
