This key to workers of Asphinctanilloides is based on Brandão, C. R. F.; Diniz, J. L. M.; Agosti, D.; Delabie, J. H. C. 1999. Revision of the Neotropical ant subfamily Leptanilloidinae. Syst. Entomol. 24: 17-36.

All of these species are now considered to be Leptanilloides.

  • Very small and not produced blunt teeth on genae (seen only in high magnifications, 80x); propodeum in profile clearly separated from mesonotum by a deep metanotal groove . . . . . Leptanilloides anae

  • Blunt teeth on genae produced (clearly seen in low magnifications, 20x); alitrunk profile continuous; it may have an impression between mesonotum and propodeum, but this does not interrupt the dorsal profile . . . . . 2

  • Propodeal dorsum separated from the declivity by an angle in lateral view; postpetiole ventral process bulging, large and rounded anteriorly . . . . . Leptanilloides amazona

  • Propodeal dorsum continuous with the declivity through a rounded curve; postpetiole ventral process not so large, straight below, and angulate anteriorly . . . . . Leptanilloides manauara
