摘　　要：记录了最近在中国记载的侵染双翅目昆虫的虫霉目两个新种，毛蚊虫疠霉（Pandorabibionis）发现于浙江庆元的毛蚊（Bibiosp.），其初生分生孢子拟卵形，多对称14.4～20．5×7．2～11.5μm（平均16．5～17.4×8．4～10．4μm），L／D1.4～2．3（平均1.7～2.0）；假根2倍粗于分生孢子梗，末端膨大为吸盘状固着器；休眠孢了外壁刺毛状，19．1～23．4μm。食蚜蝇干尸霉（Tarichiumsyrphis）发现于陕西镇坪县的斑翅狭口食蚜蝇上，其休眠孢子外被圆锥形长刺，长2.2～5．0μm，直径21．2～28．1μm。在毛蠓上发现中国新记录胶孢虫疠霉，并根据本文所采用的Humber（1989）系统，将其组合为胶孢虫瘴霉（Furiagloeosoracomb.nov.）；此外，还将北虫疫霉（Eryniaborea）组合为北虫疠霉（Pandoraboreacomb.nov．），并同时给予修订。In the present paper, 2 new species, 1 new Chinese record, and 2 newcombinations are reported. Pandora bibionis sp.nov.was recorded on marsh fly, Bibio spin Qingyuan, Zhejiang.Its primary conidia are obovoid, mostiy symmetric, 14.4 ～ 20.5×7.2 ～ 11.5μp (ave. 16.5 ～ 17.4×8.4 ～10.4μm), L /D 1.4 ～ 2.3 (ave. 1.7 ～ 2.0);rhizoids are 2 times as wide as conidiophores, with their terminal differentiated intodisk-like holdfast; resting spores are spinose, 19.1～ 23.4μm in diam.Tarichium syrphissp. nov.was recorded on syrphids, Asarcina aegrota in Zhening, Shaanxi.Its restingspores are 21.2 ～ 28.1μm in diam., with conical spines 2.2 ～ 5.0μm long on the epispore.Pandora gloeospora was recorded on moth midges (Psychodidae) for the first time in China,and was combined into Furia as Furia gloeospora comb.nov. In addition, Erynia boreawas emended and combined into Pandora as pandora gloeospora comb. nov.
