摘　　要：记述新革螨属1新种：泰安新革螨Neogamasus taianensis Ma et Sun, sp. nov.,并对峨眉常革螨Vulgarogamasus emeishanensis Ma et Wang.1996和异形新革螨Neogamasus anomalus Ma et Yan,1998进行补充描述。The present paper reports a new species of the genus Neogamasus, with supplementary descriptions of two known species of the family Parasitidae. 1 Neogamasus taianensis Ma et Sun, sp. nov. （Figs. 1, 2） Female. Length of idiosoma 656 μm, width 376 μm. Both dorsal shields almost covering entire dorsum. Anterior dorsal shield with 22 pairs of simple setae, M2 the longest, F2 and M1 shorter, ET1, ET2 and M3 minute. Posterior dorsal shield with about 30 pairs of simple setae. Prestemal shields 1 pair, triangular. Sternal shield with 3 pairs of setae and 2 pairs of pores. Metasternal shields with MSt and the 3rd pair of pores. Genital shield with 1 pair of setae. Endogynium with a row of long spines. Ventro-anal shield with 11 pairs of ventral setae and 3 perianal setae. Peritreme reaching between coxae I and II anteriorly. Tectum 3-pronged, medial prong longer than lateral ones. Movable digit of chela tridentate, fixed digit with about 7 denticles. Seta al on palpfemur and all and a12 on palpgenu branchy. Male. Length ofidiosoma 527 μm, width 280 μm. Dorsal setae as in the female. Holoventral shield with 3 pairs of sternal setae, 1 pair of metasternal setae, 1 pair of genital setae, 11 pairs of ventral setae, 3 perianal setae and 3 pairs of pores. Fixed digit of chela with a row of small denticles. Femur of leg II with 2 spurs, genu and tibia with 1 spur respectively. The new species is near to Neogarnasus cervicornis（Var Daele, 1975）, but in the new species endogynium with a row of long spines, tectum smooth between 3 prongs; however in the latter species endogynium with a bifurcate structure, tectum with small denticles between 3 prongs. Holotype ♀ , paratypes 1 ♀ and 1 ♂, ex weeds, from Tai＇an （36015＇ N, 117°08＇ E）, Shandong Province, 9 Oct 2011. Type specimens are deposited in the Institute of Plant Protection, Fujian Academy of Agricultural Science, Fuzhou. The new species is named after collected locality of type specimens. 2 Vulgarogamasus emeishanensis Ma et Wang, 1996 （Figs.
