摘　　要：双翅目的头蝇科(Pipunculidae)为小形暗色的蝇类,头大、胸小,体短、翅长,腹端向下弯钩。成虫常在田间、山野低飞徘徊,寻找飞虱。叶蝉等小若虫而产卵;幼虫内寄生于寄主体内,除同翅目害虫外也可寄生于盲蝽等半翅目昆虫。 陕西省的头蝇缺乏记载,本义描述了六个新种,以便与其他种类一并汇编在《陕西森林昆虫》中。新种的模式标本保存在北京农业大学昆虫标本室,对标本采集者及周尧教授的帮助在此深表谢意。This paper treats of descriptions of six new species from Shannxi. The diagnostic characters are given as follows: 1 Verrallia (Jassidophaga) triloba, sp. n. (Fig 1a-b)Related closely to Verrallia (Jassidophaga) chiiensis from South Korea, but differing by having three pieces of sclerites on the dorsum of the ninth segment, ra ther than two.Holotype (?), Shannxi, 1980-Ⅴ-15.2 Pipunculus (Cephalops) huashanensis, sp. n. (Fig 2a-c)Because of large size and yellow legs, this species is readily differentiated from all known Cephalops species.3 Pipunculus (Eudorylas) attenuatus, sp.n. (Fig 3a-c)This species resembles Pipunculus (Eudorylas) monothrix (Hardy) from Bismarck Island, but differs in the following features: antennal segments of the latter yellow and tibae mostly yellow, but those of the new species black.Holotype (?), Shaanxi: Louguantai, 1962-Ⅷ-13.Paratypes 2 (?) (?), same as the holotype.4 Pipunculus (Eudorylas) orthogoninus, sp. n. (Fig. 4a-d)It is similar to Pipunculus (Eudorylas) subopacus, but differs as follows: the latter with third segment of antennae brown, last section of M3-4 shorter than crossveinm, and eighth segment without membranous area. Holotype (?), Shaanxi: Louguantai, 1962-Ⅷ-13. Paratype 1 (?), Hebei: Zhuoxian County, 1965-Ⅴ-3.5 Pipunculus (Eudorylas) hardyi, sp. n.(Fig. 5a-g)Similar to Pipunculus (Eudorylas) javanensis (Meijere), but readily differentiated by the following characters of the latter: Humeri and halters yellow ovipositor more strongly curved, piercer extends to about middle of second segment, surstyli of same size.Holotype (?), Shaanxi: Louguantai, 1962-Ⅷ-13Allotype (?) , same as holotypeParatypes 2 (?) (?) , same as holotype; 1 (?) Beijing Agri. Uni., 1954-Ⅴ-23.6 Pipunculus (Eudorylas) revolutus, sp. n. (Fig. 6a-d)Related to Pipunculus (Eudorylas) mutillatus(Loew), but distinguishable by having membranous area of eighth segment square-shaped, rather than triangular.
