Remarks.

Since Aubert (1981) 's revision no comprehensive identification key has been published to the genus, although several new species have been described from Europe (e.g. Kolarov 1986, Jussila 1996). Currently, 50 species of the genus are known from Europe ( Yu et al. 2012). By using Aubert (1981) 's key the species found in the caves could not be convincingly identified. They seem to be close to Stenomacrus laricis (Haliday, 1838); however, reliable identification might not be possible without a new revision of the Western Palaearctic species of the genus. Based on some rearing records Stenomacrus species seems so be larval and/or pupal endoparasitoids of Sciaridae and Mycetophilidae ( Townes 1971, Gauld and Bolton 1988). To our best knowledge this genus is first reported here in association with hypogean environment.
