摘要
我们在研究我国茧蜂的过程中,发现了屏腹茧蜂亚科Sigalphinae中二个属,即屏腹茧蜂属Sigalphus和三节茧蜂属Acampsis的种类。这二属的种类个体较大而种数甚少,是比较稀有的类群,我们将分别作研究报道。 屏腹茧蜂属Sigalphus Latreille是一个小属,全世界已知9种(Shenefelt,1973;游兰韶等,1991)。本文报道我国发现的2个新种:黄痣屏腹茧蜂S.flavistigmus sp.
The present paper gives the descriptions of two new species of the genus Sigalphus Latrei-lle from China. All type specimens are kept in Zhejiang Agricultural University, Hangzhoa, except specimens marked with 'FAC' that are deposited in Fujiang Agricultural College, Fu-zhou.1. Sigalphus flavistigmus sp. nov. (figs. 1-2)This species can easily be distinguished from others by black with 2nd tergite reddish yellow; face convex strongly; nervulus of fore wing interstitial; r of hind wing situated near the middle of radiellan cell, cubitella curved downwards spically: stigma yellow; base of an-tenna and hind tibia reddish yellow; Length of body 7.7mm.Holotype: Lanzhou (36.0N, 103.7E), Gansu Prov., April 1, 1985, Xie Xiaoxi, No. 854023.2. Sigalphus nigripes sp. nov. (fig. 3)This species is very close to S. anomis You & Zhou, 1991, but can be distinguished from that by having the 1st abscissa of the radius 0.25 times as long as the length of 2nd; recurrent nervure strongly antefurcal; 2nd tergite 0.7 times as long as the length of 3rd.Holotype: , Jiangling (30.3N, 112.1E), Hubei Prov., Sep. 2, 1928, He Junhua, No.824762. Allotype: cf, Sheng Xian (29.6N, 120.8E), Zhejiang Prov., Oct. 24, 1963, He Junhua, No. 54093.1. Paratypes: 1, Shennongjia (31.7N, 110.6E), Hubei Prov., July 13, 1983, Mao Xiao-yuan, No.870216; 1, Yueyang (29.3N, 113.1E), Hunan Prov., Nov. 1975, Wang Binseng, No. 760015, Host: Anomis flava;1, Jiangxi Prov., 1985, The Agricultural Depatment of Jiangxi Prov., No.815971; 3, Sha Xian (26.4N, 117.7E), Fujian Prov., April 1, 1973, July 30, 1976, April 19, 1978, Chao Hsuifu, Xu Jianfei (FAC); 1, Guiyang (26.6N, 106.7E), Guizhou Prov., July 1982, Song Xuepei, No.835033.
