Etymology. From the Latin, crispus, relating to the sinuous, curly hairs of the posterior parapenicillum. Geographical distribution. Known only from the Magdalena River valley in Antioquia, Colombia (Fig. 26). Nest. Unknown. Discussion. Leurotrigona crispula sp. nov. is very similar to L. pusilla, whose workers share the very small size, the general shape of the head and all other characters listed in Diagnosis, except the vestiture of the clypeus and lower parocular area, which is longer and more abundant than in L. pusilla. Also, the males present remarkable differences in the shape of pre-genital sterna and genitalia that can be seen comparing the figures 6 – 10 (L. crispula sp. nov.) and 11 – 15 (L. pusilla).	en	Pedro, Silvia R.

Unknown. Discussion. Leurotrigona gracilis sp. nov. shares with L. muelleri mainly the size, general shape of the head and tibia III, but it can be easily distinguished by the vestiture of clypeus and parocular area, which is thinner and sparser, less branched, besides the pubescence on sides of propodeum, simple and shorter, finishing far from the base of coxa III. Variation. Some specimens are darker than the holotype, with clypeus, malar area, and scutellum entirely blackish.	en	Pedro, Silvia R. M., Camargo, João M. F.

Zanella leg (8 w, 991830 – 991833, RPSP). Paraná: Londrina, X. 1982, Juliani leg. (3 w, 2 m, RPSP). Geographical distribution. Santa Catarina to Paraíba, Brazil, and on west to Madre de Dios, Peru (Fig. 26). Nest. Very eclectic concerning nesting substrates: tree hollows – living or dry, bamboos, crevices in walls, etc. The cells are arranged in clusters. Details of nest architecture and behavior were provided by Sakagami and Zucchi (1974). Additional records about biology, flower records, etc. was compiled by Camargo and Pedro (2007: 314 – 316). Discussion. The worker of L. muelleri, as interpreted here, can be distinguished from other Leurotrigona by denser vestiture on the malar area, lower parocular area to the frons, and clypeus, clothed with silvery gray, scale-like branched hairs (Fig. 18), and pilosity longer and more plumose on posterior region of propodeal spiracle reaching about 2 / 3 or more toward base of coxa III. Features of the male pre-genital sterna and genitalia (Figs. 21 – 25) are very distinctive. Workers of Leurotrigona muelleri and L. gracilis sp. nov. share many characters (see preceding discussion) and they probably had an origin independent of the group composed of L. pusilla – L. crispula sp. nov. In relation to the karyotypes and chromosomes number, L. muelleri (2 n = 16) and L. pusilla (2 n = 30) are also very distinct (Pompolo & Campos 1995). Variation. It is possible that L. muelleri, as interpreted here, includes more than one species. There is a male, from Brazil, Maranhão, Santa Luzia, 60 km W, VII. 1983, Camargo leg., 891305, in RPSP, with the abdomen very crushed and lacking the genitalia, its general appearance is of L. muelleri, however, the visible portion of the SVI has the emarginated area in inverted V-shaped, not in inverted U-shaped as in Fig. 21, and the bifid projection of SVII, has the emargination deeper and wider with parallel sides. Workers from Rondônia, Brazil, have the branched scale-like hairs a little smaller, facial pubescence less dense; males from this region were not examined. TABLE I.
