Two new chigger mites of the gmus Aboriginesia (Acari: Trombiculidae)

摘要

Two new chigger mites Aboriginesia ludmilae sp. n. and Aboriginesia obuchi sp. n. (Acari: Trombiculidae) described from mountain areas of Switzerland and Caucasus.The genus Aboriginesia Kudryashova was erected after the systematic study of the very similar genera Hoffmannina Breiman & Jones and Heaslipia Ewing. In particular, the revision of Hoffmannina resulted in the separation of the genus Aboriginesia, which includes the Palearctic chiggers previously placed into Hoffmannina. Fifteen species aredescribed in Aboriginesia, some of which have an unclear taxonomic status (Kudryashova 1998; Stekolnikov 2001). The majority of known species come from submontane or montane localities from North Africa (Brown 2008) and Spain to Central Asia (Kudryashova1998), occurring mainly in the territories surrounding the Black Sea. This paper presents descriptions of another two Aboriginesia chiggers from Switzerland and Caucasus.
