Prenolepis melanogaster

Nothing is known about the biology of .

Identification
Williams and LaPolla (2016) - Relatively large in overall size (TL > 4.25mm); yellow-brown head and mesosoma with a dark brown to black gaster; head as broad as or broader than long (CI > 97) with round compound eyes that are spaced far apart (REL3 < 35); setae on scapes are erect.

This species is much larger and more hirsute than all other Prenolepis species and has a distinctly broad head (CI: 97–105). Prenolepis melanogaster also has a yellow-brown head and mesosoma with a dark brown to black gaster, similar to the coloration seen in Prenolepis fustinoda.

Relatively large in overall size (TL > 4.25mm); yellow-brown head and mesosoma with a dark brown to black gaster; cuticle of head, pronotum, mesopleuron, propodeum, and gaster smooth and shiny; abundant very long, erect setae on scapes, head, mesosoma, gaster, and legs; head slightly broader than long and round in shape with indistinct posterolateral corners and a weakly convex posterior margin; eyes moderately sized, convex, and placed far apart (REL3 < 35); compound eyes do not surpass the lateral margins of the head in full-face view; torulae overlap with the posterior border of the clypeus; anterior border of clypeus with a pair of prominent anterolateral lobes; mandibles with 6 teeth on the masticatory margin; ectal surface of mandibles smooth and shiny; in profile view, propodeum is domed with a rounded dorsal face; dorsal apex of petiole scale is sharply angled and forward-inclined.
