description: Key to the species of Leurotrigona Moure
1 Smaller bees, head width 0.79–0.88 mm. Workers with short malar space, as long as diameter of fl.3; integument of upper gena with fine tessellation; clypeus with simple, unbranched hairs (Figs. 1, 4); posterior margin of tibia III sinuous, posterior parapenicillum markedly sinuous, S-shaped (Figs. 2, 5). SVI of male with broad, hairy and concave area medially (Figs. 6, 11); projection of SVII simple and pointed (Figs. 7, 12) ......................................................... 2
- Larger bees, head width 1.01–1.20 mm. Workers with long malar space, as long as 2x the diameter of fl.3; integument of upper gena smooth, devoid of tessellation; clypeus with silvery gray scale-like branched hairs (Figs. 16, 18); posterior margin of tibia III slightly arched; posterior parapenicillum curved, not S-shaped (Figs. 17, 20). SVI of male with deeply emarginated area medially (Fig. 21); median projection of SVII broadened and deeply emarginated apically (Fig. 22) (only the male of L. muelleri known)............................................................................................... 3
2 Pubescence of clypeus and lower parocular area of workers relatively dense and long; in discal area of clypeus, piligerous points separated by distance shorter than hair length; some long branched hairs on juxtaclypeal area (Fig. 1). SVI of male with broad, hairy medial area deeply concave (Fig. 6); median projection of SVII slender and Yshaped (Fig. 7). Antioquia, Colombia (Fig. 26) ............................................................. Leurotrigona crispula sp. nov.
- Pubescence of clypeus and lower parocular area of workers short and sparse; in discal area of clypeus, piligerous points separated by distance about as long as hair length; only simple hairs or very shortly branched hairs on juxtaclypeal area (Fig. 4). SVI of male with broad, hairy medial area slightly concave (Fig. 11); median projection of SVII broader and V-shaped (Fig. 12). French Guiana, western Amazon, Brazil to Peru (Fig. 26) ................................ .......................................................................................................................................... L. pusilla Moure & Camargo
3 Silvery gray scale-like hairs of clypeus and parocular area of workers slightly broadened, some of them shortly branched, not reaching frons (Fig. 16); pubescence on posterior region of propodeal spiracle sparse and simple, reaching halfway or less toward base of coxa III. Male unknown. Western Amazon, Brazil (Fig. 26) ......................... ........................................................................................................................................ Leurotrigona gracilis sp. nov.
- Silvery gray scale-like hairs of clypeus and parocular area of workers, broadened, branched, up to frons (Fig. 18); pubescence on posterior region of propodeal spiracle dense and plumose, reaching about 2/3 of the distance toward base of coxa III. Genitalia and pre-genital sterna of male as in figures 21–25. Santa Catarina to Paraíba, Brazil, on west to Madre de Dios, Peru (Fig. 26) ............................................................................................ L. muelleri (Friese)
