摘　　要：拟毛突摇蚊属Paratrichocladius Santos Abreu 1918隶属于直突摇蚊亚科Ortho-cladinae,迄今全世界已知十余种。Hirvenoja(1973)对本属进行了整理。本文的记载为此属在我国的首次记录。 属征:复眼小眼面间密生细毛,触角比(AR)通常大于1;翅无大毛,腋瓣是多数缘毛;肩陷中等大小,背中鬃多数;无肛尖,抱器基节具一明显的上内突。 本文记述了采自吉林、四川省的2个新种和1个新纪录种。模式标本存南开大学生物学系。Two new species of Paratrichocladins are described and P. rufiventris (Meigen) is recorded for the first time from China in this paper. The type spcimens are deposited in the Biology Department of Nankai University.Paratrichocladius ater Wang et Zheng sp. nov. (fig. 1.)Imago male: Black, body length 3.45mm. Wing length 2.24mm, total length/wing lengeh 1.54. AR 1.8. Antepronotum without lateral setae. Dorsocentrals 15 at each side. LR1 0.58, LR, 0.47, LR3 0.52. Vein R with 5 small setae, squama with 15 setae, hypopyguim as in fig. Ib.Holotype, Jilin Province (Chang-bai Mountain), 1986-Ⅵ-25.Allies to P. tamaaier Sasa 1981 from Japan in the shape of hypopygiuni, but differs from the latter in much larger AR, larger wing and body size. The number of hairs on tergum Ⅸ and those of squama fringe also differs.Paralricocladius hamatus Wang et Zheng sp. nov.(fig. 2)Imago male: Darkbrown, total length 2.94mm. Wing length 1.89mm, total length/wing length 1.56, AR 1.5. Dorsocentrals 5 at each side. LR, 0.59, LR, 0.45, LR3 0.54, R with 6 srtae. Squama fringe 14.Hypopygium quite unique (fig. 2b): With hook-like supperior volsella and very large setae on gonocoxite, which makes this species easily distinguished from the other members of tins genus.Holotype & paratype 1, Sichuan Province (Emei Mountain), 1986-Ⅴ-17.Paratrichocladius rufiventris (Meigen) (fig. 3)New record from China. Collected from Jilin Province (Changbai Mountain),1986-Ⅵ-23.
