Barra Jordan, 1904: 274 . Bovie 1906: 278 (catalogue); Wolfrum 1929: 65 (catalogue); Blackwelder 1947: 769 (catalogue); Rheinheimer 2004: 70 (catalogue).

Type species: Barra gounellei Jordan, 1904 (by original designation) .

Recognition. Rostrum short, wider than long, flat, indistinctly emarginate at apex, not carinate, with only shallow depression before eyes. Mandibles more or less bent along the entire length, or along a substantial part, obtuse at apex. Antennal scrobes lateral, upper edge cariniform. Eyes dorso-lateral, weekly oval, coarsely granulate, only indistinctly emarginate or truncate in anterior part. Frons more or less flattened. Prothorax always wider than long, conical, from dorsal transverse carina narrowed anteriorly, disc of pronotum moderately convex. Dorsal transverse carina sub-basal to basal ( B. baruskae sp. nov.) or antebasal ( B. gounellei , B. salamandrina ) always complete, distinct. Lateral carinae of pronotum present, reaching maximally to half of length of pronotum, or shorter. Basal longitudinal carinulae (sensu Jordan 1928: 151, Trýzna & Baňař 2021: 558) present.

Key to Barra species

1 Dorsal transverse carina of pronotum sub-basal to basal, close to posterior margin of pronotum, lateral carinae of pronotum well developed, protruding, reaching half of length of pronotum ( Figs 39–43 )......................... B. baruskae sp. nov.

- Dorsal transverse carina of pronotum antebasal, distinctly distant from posterior margin of pronotum, lateral carinae of pronotum short, indistinct, barely reaching a quarter of length of pronotum............................................ 2

2 Eyes smaller, dorsal ocular index 3.17 in male. Head, pronotum and elytra with dense dark ochre to bricky pubescence. Robust species, ratio of maximum length to maximum width of elytra 1.1 ( Figs 51–55 )...................... B. salamandrina

- Eyes larger, dorsal ocular index 2.35 in male. Head, pronotum and elytra with sparse light-coloured yellowish pubescence. Elongated species, ratio of maximum length to maximum width of elytra 1.26 ( Figs 56–61 )................. B. gounellei
