本文介绍了血革螨属一新种:贡山血革螨 Haemogamasus gongshanensis sp.nov.,它采自多齿鼩鼹 Nasillus gracilis Thomas 体上。该文对新种的形态特征作了详细描述,并与近似种云龙血革螨 Haemogamasus yunlongensis Gu et Fang进行了比较。
Haemogamasus gongshanensis sp. nov. (figs. 1-18)Female: Idiosoma measuring 874(778-959) × 594(515-687) μm. Scutum measuring 799 (757-868) × 503(465-586) μm, covering almost all of dorsum, bearing 180 nude setae. Sternal plate measuring 138(135-142) × 155(147-162) μm, with 2 pairs of setae, St1 situated in presternal area. Genitoventral plate lageniform, with 12-15 genitoventral setae. Anal plate pear-shaped, with 4 accessory.Male: Idosoma measuring 599(586-616) × 412(394-424) μm. Scutum covering all of dorsum, bearing about 200 nude setae. Holoventral plate measuring 472(465-485) × 300(293-313) μm, strongly expanded behind coxa Ⅳ, with about 50 nude setae. In leg Ⅱ, coxa, genu and tibia with 1 robust spine, femer and tarsus with 2 robust spines respectively, and trochter, genu and tarsus with 1 spine more.This new species is closely allied to Haemogamasus yunlongensis Gu et Fang (in press), but palp-trochanter with a specific setae rabbit-ear shaped, tectum with long delicate branches, and coxa Ⅱ with 1 anterior dorsal robust spine.Holotype ♀ allotype ♂, and paratypes 36♀♀, 54♂♂ were collected off Nasillus gracilis Thomas from Gongshan County (27°45'N, 98°39'E) Yunnan Province, alt. 3400m, in Oct. 1935. All types are deposited in the Research Institute of Epidemic Diseases of Yunnan.
