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.

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.
