(2000): Crumomyia microps sp. n. from Austria and notes on other cavernicolous Crumomyia species (Diptera: Sphaeroceridae). - Annls hist.-nat. Mus. natn. hung. 92: 215-228. Abstract - Crumomyia microps sp. n. is described from two caves situated at 2,180-2,320 m in eastern Tyrol (Karnische Alpen, Kartitsch env., Obstans caves), Austria. The species seems to belong to troglobiont flies displaying several morphological adaptations to cavernicolous life, e.g. reduction of eyes, prolongation of arista, legs and setae, and weak sclerotization and paler pigmentation of body (abdomen in particular) being particularly distinctive in comparison with its closest relative, Crumomyia notabilis (COLLIN, 1902). The Crumomyia parentela complex was re-examined and re-classified following the discovery of 5 unusual specimens in the same caves. C. parentela cavernicola (PAPP et ROHÁCEK, 1983) is elevated to a species rank and the specimens from Obstans caves are described as C. cavernicola oculea ssp. n. A key to the identification of the C. parentela complex is presented. A survey of Crumomyia species recorded from caves is given along with a discussion about the origin of troglobiont taxa. C. tyrphophila ROHÁCEK, 1999 is recorded from Austria. With 12 figures. INTRODUCTION The Holarctic genus Crumomyia MACQUART, 1835 belongs to the speciesrichest groups of the subfamily Copromyzinae. A revision of the Crumomyia by NORRBOM & KIM (1985) enumerated 26 species but 5 others have since been added by KUZNETZOVA (1989, 1993, 1995), viz. Crumomyia nartshukae KUZNETZOVA, 1989 (Russia: Sakhalin), C. peishulensis KUZNETZOVA, 1989 (Russia: Far East), C. longiptera KUZNETZOVA, 1989 (Tadzhikistan: Pamir Mts), C. hissarica KUZNETZOVA, 1993 (Tadzhikistan: Hissar Mts) and C. zlobini KUZNETZOVA, 1995 (Kamchatka), from poorly explored parts of the Palaearctic Re-
