摘　　要：报道 2种寄生榆童锤角叶蜂AgenocimbexelminaLietWu的姬蜂 ,其中 1种为新种 :天水镶颚姬蜂HyposotertianshuiensisSheng,sp .nov .;另一种为已知种 :日本欧姬蜂Opheltesjaponicus (Cushman ,1 92 4 )。Two species of Ichneumonidae (including one new species), parasitizing Agenocimbex elmina Li et Wu (Hymenoptera: Cimbicidae) were found in Tianshui, Gansu Province, China. Specimens studied are deposited in the General Station of Forest Pest Management, State Forestry Administration, Shenyang, China.1 Hyposoter tianshuiensis Sheng, sp. nov. (Figs 1 5) Female. Body 8 0 10?mm long Fore wing 5 5 7 0?mm long. Malar space about 0 63 time as long as basal width of mandible. Postocellar line about 1 3 times as long as ocular ocellar line. Flagellum of antenna with 34 36 segments. Mesopleurum with fine leathery texture, sparse weak punctures, and 1 transverse median groove in front of mesopleural fovea. Lateral longitudinal carina of propodeum indistinct. Lateral carinae of areola very weak. Without costula. Abdominal tergites with fine leathery texture, its apical portion weakly compressed. First tergite about 2 2 times as long as its apical width. Ovipositor sheath shorter than apical depth of abdomen. Male. Body 7 8?mm long. Fore wing 5 0 5 5?mm long. Larva. Mature larva ivory white, 8 9?mm long. Cocoon. Cocoon is very thin, french grey, about cylindrical (very weakly flat), 10 11?mm long. Holotype ♀, Tianshui, Gansu, China,12 Apr. 2001, WU Xing Yu, emerged from the cocoon of Agenocimbex elmina indoors. Paratypes: 8♀♀, 9♂♂, same data as holotype; 24♀♀, 12♂♂, 8 Apr. 2002, SHENG Mao Ling, other data as holotype. This species is similar to H. vierecki Townes, Momoi & Townes, 1965, but can be distinguished from the latter by the following characters: postocellar line about 1 3 times as long as ocular ocellar line; propodeum without costula and apical transverse carina; middle section of median longitudinal carinae (la teral carinae of areola) disappeared or very weak and indistinct; hind tarsi (except apices of tarsus 2 4 blackish brown) yellowish brown. H. vierecki has postocellar line double length of ocular ocel
