记述阳厉螨属１新种，即叉阳厉螨Ａｎｄｒｏｌａｅｌａｐｓｔｒｉｆｕｒｃａｔｏｉｄｅｓｓｐ．ｎｏｖ．。
Androlaelaps trifurcatoides sp.nov. (Figs.113)
Adult.Body yellow,oval,♀ average 554μm long and 304μm wide, 437μm long and 264μ
m wide.Anterior part of dorsal shield broad,posterior part strongly contracted.Dorsal shield
setae 37 pairs,needleshaped;distance between D 5D 6=D 6 D 7,D 7 D 8>D 6 D 7,distance
between D 5=D 6,D 7>D 6.Presternal shields 1 pair,large,with even polypunctate pattern on
surface.In female,sternal shield bears 3 pairs of setae and 2 pairs of pores,metasternal setae
and 3rd pair of pores on cuticle interior to endopodalia;genitoventral shield narrow,its lateral
margins convex at middle;anal shield similar to inverted pear in shape,Ad situated a little
before level of middle of anus,Ad and PA longer than anus;movable digit of chela with 2

some long spines and 3 whip like setae. The new species is similar to A.trifurcatus Wang
et Li,1965,but in the new species posterior narrow part of dorsal shield longer;distance
between dorsal setae D 5 D 6=D 6 D 7,D 7 D 8>D 6 D 7,distance between D 5=D 6,D
7>D 6;genitoventral shield of female longer,the widest at middle of the shield.In the latter
species posterior narrow part of dorsal shield short;distance between dorsal setae D 5D 6>D
6D 7,D 7-D 8=D 6 D 7,distance between D 5>D 6,D 7<D 6;genitoventral shield of female
shorter,the widest at posterior part. Holotype ♀,paratypes 3 ♀♀,1,1 deutonymph and 1
protonymph,from humus soils under trees,Wuhan City (30°31′N,114°16′E),Hubei
