Key to Females of the Genera of Brachycistidinae

1 Hindcoxa with longitudinal carina on inner margin ( Fig. 2 ); occipital carina ventrolaterally angulate ( Fig. 1 )................................................................... Colocistis Krombein

­ Hindcoxa without longitudinal carina on inner margin; occipital carina ventrolaterally

evenly curved ................................................................................................................ 2 2 Scape apicolaterally lobed ( Fig. 11 ); occipital and hypostomal carinae widely separated, separation as long or longer than length of hypostomal fossa; occipital carina obsolescent ventrally.................................................. Stilbopogon Mickel & Krombein

­ Scape cylindrical, not apicolaterally lobed ( Fig. 12 ); occipital and hypostomal carinae usually separated by less than length of hypostomal fossa; occipital carina complete ventrally....................................................................................................................... 43

3 Mandible with inner margin below largest laterally projecting subapical tooth serrate or with three or more small teeth ( Fig. 6 )........................................... Brachycistis Fox

­ Mandible with inner margin below largest laterally projecting subapical tooth smooth, without serrations or small teeth ( Figs. 7, 9, 10 )........................................................... 4

4 Mesopleuron strongly convex medially in dorsal view ( Fig. 3 ); maxillary palpus about as long as hypostomal fossa.........................................Glyptacros Mickel & Krombein
