Two new species of Suctobelbid mites from China ( Acari:Oribatida:Suctobelbidae )

This paper describes two new species of the genera Allosuctobelba and Suctobelbella ( Suctobelbidae ).All type specimens are deposited in the Dept.of Biology,Norman Bethune University of Medical Sciences. Allosuctobelba menglunensis sp.nov.(figs.1￣4).Body length 352(372)408μm,width 196(208)222 μm.The new species is very closely related to the known Chinese species A. huangshanensis Wen,1993 and the Japanese species A.tricuspidata Aoki,1984.They are distinguishable from one another by following keys:1(2) sensillus short,pedicle part longer than head part and extremity part……A. Tricuspidata Aoki,1984 2(1) sensillus long,pedicle part be equal to or shorther than extremity part.3(4) notogastral setae short,lyrifissure im inserted at a prolateriorly seta ti ,anterior part of Apodemata Ⅳ extending forward not connected with apo.sj,body length longer (550 μm…… A.huangshanensis Wen,1993 4(3) notogatral setae long,lyrifissure im in located posterolateriorly to seta ti ,anterior part of apodemata Ⅳ extending forward to be connected with apo.sj ,body length smaller(352￣408 μm…… A. menglunensis sp.nov. Holotype and 6 paratypes(93—1908),July,1993,Menglun in Yunnan Province.All type specimens ex litter Suctobelbella sinica sp.nov.(figs.5￣8).Body length 172(173)174 μm,width 106(111)116 μm.The new species somewhat resembles S. Claviseta (Hammer,1961) from peru,but differs from latter one species in the following points:1)bearing two teeth on each side of rostrum,first tooth longer than second one; 2)sensillus has ellipse shape head,without pointed at the tip; 3)6 pairs setae of notogaster are spear shaped,the stalk distinct longer than the head,rounded at the tip. Holotype and 1 paratype (93-1930),July,1993,Menglun in Yunnan Province.all type specimens ex litter.
