Material examined. Holotype ♂: BOL[IVIA], [Santa Cruz], Cuatro Ojos, XI.1911, Steinbach col., Carn. Mus. Acc 5074 (CMNH). New material: BRAZIL: Amazonas, 1 ♂, Manaus Puraquequara, 11.XII.1998, Arm[adilha] Möricke, J.F.Vidal col. (INPA); ARGENTINA, 1 ♂, Tucumán, between Choromoto + Higuera, 900m, sweep, 19.I.1999, J.M. Sharkey col. (CNCI).
Diagnosis. MALE (Fig. 20). Black. Mandible with two apical teeth (Fig. 21). Clypeus with broadly subrounded median lobe. Antennal scrobe not carinate. Frons coriaceous. Vertex slightly convex. Pronotal disc with anterior corner angulate and produced; anterior carina thick and sharp; median carina weak, absent on posterior third of disc; lateral margin not carinate; posterior margin paralleled by some punctures; side of disc with ventral margin not carinate. Scutellar pit subrounded. Mesopleuron with subtegular groove wide anteriorly; anterior fovea elliptical; upper fovea subrounded; lower fovea with upper margin mostly absent (Fig. 22). Genitalia (Figs 23, 24): paramere very unusual, sinuous, base very narrow, inserted into basiparamere on inner corner of dorsal side, apex sharp; cuspis elongate, its apex almost aligned with paramere apex; digitus apex aligned with cuspis apex; aedeagus wide, apical half little narrower than basal half, short, only 0.64 × as long as genitalia length, without constricted between apical and basal halves; ventral surface with small projection ventrad; base of apodeme not dilated. FEMALE unknown.
Distribution. Brazil (Mato Grosso, Minas Gerais, São Paulo, Paraná, Santa Catarina), Bolivia, Argentina (Salta, Misiones), * Argentina (Tucumán).
Variation. One specimen from Tucuman with median pronotal carina short and very weak.
Remarks. The aedeagus is wide and short as most of species of Epyris. Evans (1973) identified 1 ♀ of Bakeriella from Brazil (Santa Catarina, Nova Teutônia) as B. cristata stating that it is like the male. It has the scutellar pits elliptical and separated by a broad, flat-topped ridge; the pronotum with the median carina weakly developed on the posterior third, otherwise absent; and the mandibles with two large apical teeth.
Evans (1973) speculated the possibility of 1 ♀ from Santa Catarina (Brazil) to be B. cristata, because of the separated elliptical scutellar pits and the dark green metallic frons. However he did not indicated the repository and I was not able to locate this female.
