报道了采自我国东北地区辽宁省兴城市原尾虫1新属辽宁蚖属Liaoxientulus gen.nov.及新种兴城辽宁蚖Liaoxientulus xingchengensis sp.nov.和该属的1个未定名种Liaoxientulus sp.,新属属于蚖科屠蚖亚科。新属与采自东北黑龙江省的屠蚖亚科伊春蚖属Yichunentulus Yin,1980形态最为相近,其与后者主要差别在于下唇须和前跗内侧感觉器b'不同,伊春蚖属下唇须有1根膨大的感觉器和4根刚毛,前跗内侧感觉器b'缺如;新属下唇须退化,其上感觉器缺如,刚毛只有3根,但是前跗内侧感觉器b'存在。新属现有2个种,均为此次新发现,其中1个种为新种Liaoxientulus xingchengensis sp.nov.,另外1个种为未定名种Liaoxientulus sp.。新种正模1只和副模1只以及该属另1未定名种标本保存在中国科学院东北地理与农业生态研究所,新种另2只副模保存在上海植物生理生态所昆虫博物馆。
Liaoxientulus gen. nov. is created to accomodate Liaoxientulus xingchengensis sp. nov. and one undetermined Liaoxientulus sp., found from Northeastern China. The new genus belongs to the subfamily Tuxenentulinae Yin, 1983 of the family Acerentomidae. The new genus is close to Yichunentulus Yin, 1980, also known from Northeast China. Liaoxientulus differs from Yichunentulus in the structure of the reduced labial palp, and the presence of sensilla b′ on foretarsus. The labial palp in Yichunentulus has four setae and one large sensilla; but only with three setae in the present genus, and the sensilla is absent.
