摘要
伪瘤姬蜂属Pseudopimpla Habermehl,1917隶于瘤姬蜂亚科Pimplinae(=长尾姬蜂亚科Ephialtinae)瘤姬蜂族Pimplini,主要特征是产卵管强度侧扁,直或稍向下弯;背瓣端部背缘有锯齿状齿,腹瓣端部扩大,包围背瓣;腹瓣末端有许多近于垂直的小波纹状细脊;产卵管鞘长约为前翅长的0.24~0.30倍。迄今为止,本属尚无寄主记录。但我们最近在河北槲梢螟幼虫和辽宁槲茎蜂幼虫(学名均不知)中育出了一些伪瘤姬蜂。伪瘤姬蜂属是个小属,全世界已知仅3种,1种分布于阿尔及利亚,另2种分布于南欧。本文报道我国2新种:光腰伪瘤姬蜂P.glabri propodeum sp.nov.和全脊伪瘤姬蜂P.carinata sp.nov.。模式标本除注明者外均存于浙江农业大学生物防治研究室。
Two new species of the genus Pseudopimpla Habermehl, 1917 from China are described in this paper. They are separated from each other by the following key:1. Occipital carina absent doso-medially (Fig. 2); propodeum without carinae and petiolar area not bounded (Fig.4); length of 1st tergite 1.6-2.0 times as long as its apical width, its median dorsal carinae not distinct except near the base (Fig.4); inner orbit yellow, the remaining black; mesoscutum black; mesopleurum without yellow spot above prepectalcarina; hind tibia yellow at basal 0.25, the remaining dark brown. Zhejiang, Hunan……P glabripropodeum, sp. nov.Occipital carina complete but decurved doso-medially (Fig.5); propodeum with a large subpentagonal petiolar area bounded basically by a distinct Ⅲ-shaped carina (Fig.6); length of 1st tergite 1.25-1.4 times as long as its apical width, its median dorsal carinae reaching beyond the middle (0.66) (Fig.6); orbit entirely black; mesoscutum with two yellow submedian longitudinal strips; mesopleurum with a round yellow spot above prepectal carina; hind tibia black at ends whereas yellow at middle. Liaoning, Hebei, and Shandong P. carinala. sp. nov.1. Pseudopimpla glabripropodeum, sp. nov.This species may be distinguished from its congeners by that propodeum is without carinae except apical remnant of lateral longitudinal carinae and its petiolar area is not bounded to form a large subpentagonal area (Fig.4).Holotype (?) , Hangzhou (30.2°N, 120.1°E), Zhejiang, 18-Ⅴ-1984, He Junhua, No. 842689. Allotype (?) , Hangzhou, 13-Ⅴ-1980, He Junhua, No. 801391. Paratypes: 1 (?) , same data as allotype; 1 (?), Hangzhou, 6-Ⅴ-1980, Zhou Cai'e, No. 801488; 1(?) , Changsha (28.2°N, 112.9°E), Hunan, 15-Ⅴ-1985, Hu Changdi, No. 878953.2. Pseudopimpla carinata, sp. nov.This species differs from its congeners in that occipital carina is complete and slightly decurved at midline (Fig. 5).Holotype (?), Mt. Tai (36.4°N,117.2°E), 8-Ⅹ-1981. Fan Di, No. 840772. Allotype (?) , Fengcheng (40. 4°N, 124. °E), Liaoning, Ⅹ-1980, Wei Chenggui, No. 814644. Paratypes: 1 (?) , Xinglong (34.7°N, 114.4°E), Hebei,Ⅶ-1963, Huang Xiaoyun, No. 871150; 1 (?), Sitaizi (40.4°N, 123.9°E), Liaoning, 15-Ⅵ-1962, Zhao Youxin, No. 871965.All the type specimens are deposited in Zhejiang Agricultural University, except one paratype of P. carinata sp. nov., which is in Beijing Agricultural University.
