Key to genera of Brachiacanthini

1. Protibia nearly always with narrow, outwardly serrate flange ( Fig. 10 ), rarely with outer margin smooth ( Fig. 493 , 511 ); apex of male abdominal ventrite 5 with small tubercle at least partially concealed by a dense clump of setae on each side of median depression ( Fig. 18, 19 ); phallobase of male genitalia small, unmodified, basal lobe asymmetrical ( Fig. 67 ) ..................................... ......................................................................... Serratitibia Gordon and Canepari , n. gen.

— Protibia with large, wide, outwardly serrate flange ( Fig. 31, 38 ), or flange lacking serrations, or without flange; apex of male abdominal ventrite 5 rarely with tubercle on each side of median depression; phallobase of male genitalia, nearly always modified, basal lobe asymmetrical or symmetrical ( Fig. 51 , 39 ) ........................................................................................................... 2

2(1). Protibia with wide, outwardly serrate flange ............................................................................... 3

— Protibia with or without flange, if flange present, then not outwardly serrate ......................... 4

3(2). Primary abdominal pores present between ventrites 4–5; basal lobe of male genitalia symmetrical ( Fig. 51 ) ............................................................................................................ Hinda Mulsant

— Primary abdominal pores not present between ventrites 4–5; basal lobe of male genitalia asymmetrical ( Fig. 32 ) ............................................................................... Cleothera Mulsant

4(2). Primary abdominal pores present between ventrites 4–5 ( Fig. 23 ), if pores apparently absent, then protibia with large flange ( Fig. 14 ); protibia usually with large or small flange smooth on outer margin ( Fig. 13, 14 ) ................................................................ Dilatitibialis Duverger

— Abdomen lacking primary pores between ventrites 4–5; protibia variable but rarely with flange ..................................................................................................................................................... 5

5(4). Protibia with external tooth, tooth large ( Fig. 16 ), reduced ( Fig. 15 ), rarely absent; male genitalia with basal lobe symmetrical (except B. bistripustulata ) ................ Brachiacantha Mulsant

— Protibia without tooth; basal lobe of male genitalia nearly always asymmetrical ..................... 6

6(5). Protibia distinctly flanged; dorsal surface black with metallic greenish or bluish tint; epipleuron wide medially, strongly descending externally ............................................. Tiphysa Mulsant

— Protibia occasionally flanged, but not widely so ( Fig. 12 ), usually without flange or with narrow flange ( Fig. 11 ); dorsal surface not black with metallic tints; epipleuron not strongly descending externally ................................................................... Cyrea Gordon and Canepari , n. gen.
