Eulaelaps petauristae sp. nov. (Figs.1 6) Diagnosis. This new species is similar to Eulaelaps pratentis Zhou, 1981 and Eulaelaps silvestris Zhou, 1981, but differs from the latter two species in the following diagnostic characters: 1) the lyrifrom organs of the posterior part of peritrematal plate broader and larger, and its width about 2/3 of the width of peritrematal plate; there is a broad and deep brown sclerotization around the membrane of lyrifrom pore on the peritrematal plate, it is quite unique; 2) the incision sinus invaginated of lateral margin of genitoventral plate at the level of coxa Ⅳ slightly wider than these in the latter two species and with an obligue upwards sinus; 3) the anterior apex of peritreme extending beyond the anterior margin of coxa I; 4) the narrow triangular anal plate and its anterior margin convex in the middle portion differing from that of Eulaelaps pratentis anal plate which is equiangular trianqular and with nearly straight anterior margin; 5) about 275 dorsal setae in the new species, whereas in the Eulaelaps silvestris about 190 dorsal setae. Holotype female, paratype 1 female, collected off Petaurista clarkei from Shennongjia forest region on May 6, 1994. Holotype is deposited in the Medical Entomology Gallery, Institute of Microbiology and Epidemiology, Academy of Military Medical Sciences, Beijing, and paratype 1 female deposited in the Institute of Parasitic Diseases, Hubei Academy of Medical Sciences.
