川、滇束毛隐翅虫属初记(鞘翅目:隐翅虫科,大眼隐翅虫亚科)

A PRELIMINARY STUDY ON DIANOUS LEACH FROM SICHUAN AND YUNNAN PROVINCES, CHINA (COLEOPTERA: STAPHYLINIDAE, STENINAE)

束毛隐翅虫属(Dianous Leach,1819)为大眼隐翅虫亚科(Steninae)的二属之一。根据眼稍小,后颊较长,第9腹板端侧各有一束长毛,不难与亚科中另一属(大眼隐翅虫属Stenus)区分。该属主要分布于南亚、东南亚及东亚地区,全世界已知91种(Puthz,1981)。中国已记载的21种中,四川分布2种,云南8种,台湾、福建等10种,香港1种。本文就川、滇标本,报道已鉴定出的14种(其中包括7新种,1新亚种,1中国新纪录)。模式标本保存在四川师范学院生物系。
