摘　　要：记述厚厉螨属1新种：宁夏厚厉螨Pachylaelaps ningxiaensis sp．nov．，模式标本采自宁夏盐池县柳阳堡地区台风蜣螂（ScarabaeustyphonFischer）体。保存于军事医学科学院微生物流行病研究所昆虫标本馆，北京。A new species of the genus Pachylaelaps is described in the present paper. Pachylaelaps ningxiaensis sp. nov.（ Figs. 1-4） Female. Length ofidiosoma 516-570 （av. 536） μm, width 323-355 （av. 341） μm. Dorsal shield almost covering entire dorsum, 505-559 （av. 525） μm long and 312-344 （av. 330） μm wide. Dorsal shield setae 30 pairs, long and simple, but F1 shorter, F2 very short, S8 （19 μm） distinctly shorter than S7 （75 μm）, S8 ：S7 =1：4. Sterno-metastemal shield weakly reticulated on surface, bearing 4 pairs of setae. Anterior part of genito-ventral shield distinctly contracted, fissure between genito-ventral and peritrematal shields very broad, posterior margin of the shield convex, with 2 pairs of setae. Anal shield triangular, Ad situated behind level of anterior margin of anus, both Ad and PA longer than anus. Peritreme reaching to anterior part or anterior margin of coxa II anteriorly. Metapodal shields club-shaped, distant from peritrematal shield. Tectum with about 6 bifurcate spines at distal margin, lateral margins with many small denticles. Tarsus II with a spine. The new species is similar to Pachylaelaps volkovae Goncharova et Koroleva, 1974 and Pachylaelaps brachperitrematus Koroleva, 1977, but in the new species dorsal setae long, its end near or reaching to or beyond base of next seta; fissure between genito-ventral and peritrematal shields very broad. In the latter 2 species dorsal setae short, its end distant from base of next seta; fissure between genito-ventral and peritrematal shields narrow. Holotype , paratypes 8 , off scarabaeid beetle, from Yanchi County （37° 50＂ N, 107° 28＂ E）, Ningxia Hui Autonomous Region, 29 May 2010. Type specimens are deposited in the Entomology Gallery, Institute of Microbiology and Epidemiology, Academy of Military Medical Sciences, Beijing. The new species is named after collected locality of type specimens.
