Specimen Labels


Williams and LaPolla (2016) - Gracile with elongate legs (HTI > 185), antennae (SI > 185), and mesosoma (BLI > 175); in profile view, the mesosoma is especially slender and has a distinct shape, with the propodeum much taller than the pronotum; no erect macrosetae on the propodeum; petiole is narrow and elongate (PetWI < 55); scale of petiole is rounded at its apex.

This species can most easily be distinguished from Prenolepis subopaca by its shiny cuticle and lack of pubescence on the dorsal surface of the mesosoma and gaster. By contrast, P. subopaca has thick patches of pubescence on the mesosoma, propodeum, and gaster and a very dull and finely sculpted cuticle. Prenolepis jerdoni has very large compound eyes that are similar to those of Prenolepis naoroji, but P. naoroji has a distinct light blue cuticular iridescence and a shorter petiole than P. jerdoni.
