摘要
本文记述在陕西小哺乳动物体表采得的寄螨亚科5属10种,除前已报导过的小真革螨Eugam-asus minus Gu et Huang,1990外,其中有3新种:贫毛常革螨 Vulgarosamasus oligochaetus sp.nov、、多毛常革螨 Vulgarogamasus multisetus sp.nov.与掌状常革螨 Vulgarogamasus palmatussp.nov.;以及 1国内新纪录:伦勃常革螨 Vulgarogamasus remberti(Oudemans.1912)。文中列出了各螨的采集记录,对新种则绘图加以描述,并列举出与相近种的鉴别。
The present paper deals with 5 genera and 10 species of Parasitinae from Shaanxi Pro-vince, among them Vulgarogamasus oligochaetus. Vulgarogamasus multisetus and Vulgarogama-sus palmatus are new to science; Vulgarogamasus remberti (Oudemans, 1912) is recorded for thefirst time from China. Type specimens are depocited in Shaanxi Sanitation and Anti-EpidemicStation. Valgarogamasus oligochaetus sp. nov. (figs. 1-7) Holotype was collected in the nest of birds, on May 7, 1983, from Ningshan County,33.5°N, 108.5°9, Shaanxi Province. The new species with particular shaped tectum; inner side of peritreme bearing denticles;only 2 pairs of sternal setae, Sta and MSt absent, by these characteristics may be easily differen-ciated from other species in the genus. Vulgarogamasus multisetus sp. nov. (figs. 8-13) Holotype and paratype 1 were collected from nest of Cricetus triton de Winton, on Oct.27, 1982, from Changan County (34.2°N, 108.9°E), Shaanxi Province. Most species of Vulgarogamasus bearing 21-23 setal pairs on podonotal plate and about20 (the greatest number 27) setal pairs on opisthonotal plate, but the new species bearing 34setal pairs on podonotal plate and 54 setal pairs on opisthonotal plate, 2 times more than thegeneral. Vulgarogamasus palmatus sp. nov. (figs. 14-21) Holotype was collected from cave of Ochotona thibetana Milne-Edwards, on Apr. 26,1984, from Shangnan County (33.8°N, 110.8°E), Shaanxi Province. This new species is near to the former new species, the differences are idiosoma smaller;dorsal setae lesser; with a spine on the basal portion of palp femur; a crest on trochanter Ⅳ,and a long seta on tarsus Ⅳ. Vulgarogamasus remberti (Oudemans, 1912) The first record from China. 1 female was collected off Cricetus triton de Winton, onOct. 29, 1982, from Changan County.
