摘要本文记述了中国地区雀形目鸟类上的两个新种：翼叶螨Pteroherpus pomatorhinae sp.11月从斑胸弯刀鱼Pomatorhinus ruficollis Hodgson(雀形目，Timaliidae)和中国翼手鸟Pteroherpus chinensis sp.11月从斑嘴雀形目(雀形目，斑嘴鸟科)获得。Pteroherpus pomatorhinae sp.11月属于双倍体种群。Pteroherpus pomatorhinae sp.11月前背侧屏蔽延长，后裂体缩窄至后端，后裂体叶略微延长，并有两对小的附加硬膜(一对在背侧，在前背侧和子宫顶端之间，一对在生殖器后方)。Pteroherpus pomatorhinae sp.的雌虫11月有一对子宫前角硬骨板、一对中央硬骨板、一对部分分成外侧和内侧碎片的侧上裂口硬骨板和一对侏儒硬骨板。中央片岩具有几乎平行的侧缘和凹陷的后缘，后体盾片的后端由一座厚桥连接。中国蕨类(Pteroherpus chinensis sp.)11月属于Hoplophorus物种组。中国翼手蛾Pteroherpus chinensis sp.11月前背侧盾牌略长于宽，后峡部中等收窄至后端，后峡部小叶宽而短，肛门盾形不规则。中国翼手蛾Pteroherpus chinensis sp.11月将子宫前侧巩膜与前背侧盾构融合，形成复合盾、中央巩膜、一对外侧肩部巩膜和一对侏儒巩膜。中央片岩边界清楚，呈纵板状，后方略窄，前缘略凹，侧缘凹陷，后端强烈凸起。
Abstract Two new pteronyssid feather mite species are described from passeriform birds in China: Pteroherpus pomatorhinae sp. nov. from the Streak-breasted Scimitar-babbler Pomatorhinus ruficollis Hodgson (Passeriformes, Timaliidae), and Pteroherpus chinensis sp. nov. from the Collared Finchbill Spizixos semitorques Swinhoe (Passeriformes, Pycnonotidae). Pteroherpus pomatorhinae sp. nov. belongs to the diploplax species group. The males of Pteroherpus pomatorhinae sp. nov. have the prodorsal shield elongated, the opisthosoma narrowed to posterior end, the opisthosomal lobes slightly elongated, and two pairs of small additional sclerites (one dorsally, between prodorsal and hysteronotal shield, and one ventrally posterior to genital apparatus). The females of Pteroherpus pomatorhinae sp. nov. have a pair of anterior hysteronotal sclerites, a central sclerite, a pair of lateral opisthosomal sclerites partially split into lateral and inner fragments and a pair of pygidial sclerites. The central sclerite has almost parallel lateral margins and concave posterior margin, and the posterior ends of the fragments of opisthosomal shields are connected by a thick bridge. Pteroherpus chinensis sp. nov. belongs to the hoplophorus species group. The males of Pteroherpus chinensis sp. nov. have prodorsal shield slightly longer than wide, the opisthosoma moderately narrowed to posterior end, the opisthosomal lobes wide and short and the adanal shield with irregular form. The females of Pteroherpus chinensis sp. nov. have the anterior hysteronotal sclerite fused with the prodorsal shield into a complex shield, a central sclerite, a pair of lateral opisthosomal sclerites and a pair of pygidial sclerites. The central sclerite is well delimited, and shaped as a longitudinal plate, slightly narrower posteriorly, with slightly convex anterior margin, concave lateral margins, and strongly convex posterior end.
