The Xylophagidae are slender, basal Brachycera reaching lengths of 6.6-19.0 mm, with short hairs and without bristles. Antennal flagellum consisting of 7-8 flagellomeres, the last one short and rounded; clypeus flat and palpi clavate; vein C surrounding entire wing and R5 ending near wing tip; all tibiae with spurs. The larvae possess a deeply sclerotised conical head capsule and sclerotised plates on the thorax and the terminal segment. The larvae live as saproxylic predators of other insect larvae under bark and in decaying wood. The adults are therefore not too rare in deciduous forests and along their margins.

Five species are known from Europe (Rozkošný 2007), four of them occur in the Czech Republic and three in Slovakia; no additional species has been recorded since the PCV2 (Rozkošný 1997). General information on the morphology, biology and development was recently summarised by Nagatomi and Rozkošný (1997). Identification keys to the adults of Central European species are included in studies by Trojan (1956) and Krivosheina and Mamaev (1972). The larvae can be identified according to the latter authors (Krivosheina & Mamaev 1966). Chandler (1998) designated a lectotype for Xylophagus ater Meigen, 1804 and found that this species is identical with X. compeditus as treated in the recent European literature. For the species known as X. ater of authors (not Meigen, 1804), the name X. kowarzi (Pleske, 1925) is used (Rozkošný 2007, Rozkošný et al. 2005).
