Male . First antennae unsegmented or partially multi-articulated with incomplete rings. Second antennae basal antennomere variously ornamented but lacking a digitiform process; distal antennomere as in the family but in a few cases ( B. achalensis César, 1985 ; B. paludosa (Müller, 1788) ; B. papillata Rogers, De los Ríos & Zúñiga) with a basal branching ( Linder 1941 ; Cohen 2012 ). Mouthparts as in the family. Rigid basal portion of gonopods each bearing a medial spine-like projection; eversible portion of gonopods elongate, usually reaching the first abdominal segment. Genital segments prominent or not in lateral view. Vas deferens not describing a loop. Usually with sexual dimorphism in thoracopods, mainly in the shape and setose armature of endopodites (shape and number of setae). Female . First antennae as in the male. Second antennae as in the family, sometimes with an additional medial bulge or protuberance with setae or spinulae, rarely with a stout spine or medial projection, which together with the apical projection seem to form a cheliform appendage ( B. achalensis ; B. iheringi Lilljeborg, 1889 ; B. cornigera Lynch, 1958 ; B. hiberna Rogers & Fugate, 2001 ) ( Lynch 1958 ; Cohen 1987 ; 1995 ; Rogers & Fugate 2001 ). Mouthparts as in the family. Thoracopods with sexual dimorphism.
