Cyrtoma simplicipes Zetterstedt, 1842: 331 .

Material examined (73, 6Ƥ). Czech Republic: 1Ƥ, Písek-Čimelice (car net), 28.vi.1992; 2Ƥ, Vráž nr. Písek, 49°23'N, 14°08'E, 400 m, 30.v.1994; 23, 1Ƥ, same locality, 2.vi.1994; 1Ƥ, Čertova voda nr. Dĕčín, 130 m, 50°48'47.3''N, 14°13'35.3''E, meat-baited Malaise trap, 21.v.-20.vi.2009; 13, Čelákovice, 4 km E, lowland wood, 50°10'N, 14°49'E, 180 m, 6.vi.1990; 1Ƥ, Přerov nad Labem, river bank, 50°11'N, 14°48'E, 180 m, 6.ix.1983 all M. Barták—(CULSP). Finland: 13, Tvärminne, R. Frey; 13, Liminka, R. Tuomikoski (NHMH). Russia: 13, Tytärsaari (= Bolshoy Tyuters), W. Hellén; 13, Suistamo, R. Tuomikoski (NHMH).

Diagnosis. An easily recognisable species due to narrow (apically almost not swollen) hind tibia and peculiar genitalia with shortened postgonites (bearing small triangular-shaped extension best visible in ventral view), nearly triangular-shaped left phallic hook (somewhat similar to the situation in the B. pilosa complex), not visible in Chvála (1983, fig. 309, p. 145) or Collin (1961, fig. 92, p. 263) is probably due to the occasional alignment of the cranial part of the hook with the median extension of the postgonites, and short and broad hypandrial processes armed with apical setae.

Distribution. Europe. Published record from Italy (Raffone 2006) was based on a misidentification [not included in recent catalogs by Chvála (2012) and Yang (2007)].

Remarks. Tuomikoski (1955) provided a short redescription and illustration of the hypandrium. Collin (1961) also wrote a short redescription, illustrated the male genitalia and hind leg, and provided notes to the synonymy. Chvála (1983) gave a redescription, synonymy, lectotype designation, and illustrations of the genitalia, face, antenna, and hind leg. The species is rather isolated in position without clear affinities.
