|The Ants of
SUBFAMILY MYRMICINAE - Genus Meranoplus
|Contents - Myrmicinae - MYRMICINAE Introduction|
In Tribe MERANOPLINI.
Diagnostic Features - Antennae 9-segmented with a 3-segmented club; antennal scrobes well developed and deep. Eyes situated towards the posterior of the ventral border of the scrobes. Promesonotum fused, strongly margined all around, projecting posteriorly as a shelf which overhangs the near vertical propodeum. Posterior margin of shelf with a number of teeth or spines. Propodeum unarmed or bidentate or bispinose. Petiole and postpetiole scale-like. All are brown to dark brown, with all dorsal surfaces having abundant, long, soft hairs giving the ants a furry appearance.
Arnold (1917) gave a transcription of Smith (1854 - unavailable in HNS) and a key to South African forms; these are at . Botlon's (1981a) revsion is at .
