Bracon (Glabrobracon) Fahringer: Masi 1941: 46; Tobias 1957: 486, 1958: 95, 1959: 896; Papp 1962: 353; Tobias 1971: 214; Papp 1974: 415.

Bracon (Orthobracon) Fahringer, 1927: 232, 1928: 595; Tobias 1957: 443, 1971: 212; Papp 1974: 415. Type species: Bracon exhilarator Nees, 1834 (designated by Tobias 1959). Synonymised by Papp 2012.

Diagnosis.

Antenna long, usually as long as body, flagellomeres longer than wide; hypoclypeal depression small, as wide as its distance from eye or slightly more; maxillary palpi moderately long, usually shorter than height of head; fore wing vein SR1 reaching tip of wing; second submarginal cell of fore wing usually medium-sized; metasomal tergites often entirely smooth or only basal tergites weakly sculptured, rarely apical tergites somewhat sculptured and propodeum sculptured along middle (sometimes with longitudinal ridge) and ovipositor clearly shorter than metasoma.

Biology.

Most species are idiobiont ectoparasitoids of larvae of Lepidoptera ( Tortricidae , Geometridae , Argyresthiidae , Gelechiidae ), of Coleoptera ( Cerambycidae , Curculionidae , Attelabidae , Brentidae ) and of Diptera ( Anthomyiidae , Tephritidae ) and some species are parasitoids of larvae of Hymenoptera ( Tenthredinidae , Cynipidae ) ( Fitch 1883; Möller 1886; Fahringer 1927; Barnes 1935; Telenga 1936; Fulmek 1968; Tobias 1986; Ghahari and Fischer 2012; Yu et al. 2016).

Distribution.
