Nothing is known about the biology of Prenolepis angularis.

Identification

Williams and LaPolla (2016) - Obtusely angled propodeum with flat dorsal and posterior faces; erect setae on scapes and legs; light blue cuticular iridescence.

This species and Prenolepis naoroji are the only Prenolepis to have a light blue cuticular iridescence. Prenolepis angularis can most easily be distinguished from P. naoroji by its obtusely angled propodeum, smaller compound eyes that do not surpass the lateral margins of the head in full-face view, and erect setae on the scapes. Prenolepis angularis is also much less hirsute than P. naoroji and its macrosetae are shorter in length.
