Oligomyrmex (Aneleus) species undet.
Formerly in my ant guide and earlier versions of this website as
Oligomyrmex
silvestrii but clearly not matching Santschi's
description and illustration.
Minor, previously thought by me, on grounds of size, to be the
major - TL 1.59 mm, HL 0.45, HW 0.36, SL 0.31, PW 0.23; now (2004)
I feel that it is in a fact the minor from the long scapes -
rarely reaching the mid-point of the face in the major morph of
any species. The closest comparison seems to be with the minor of
Oligomyrmex
punctatus from Kenya, although that is about 2/3 the
size; another apparently similar minor is menozzii from
Fernando Po I.
Colour orange-brown. Antennae 11-segmented. Sculpturation of
head a loose reticulation, dorsomedial area smooth; pronotum
nearly all smooth; lateral mesonotum and propodeum punctate. Erect
hairs short, fine and sparse, most being on the dorsal alitrunk.
Anterior margin of pronotum well defined; promesonotum in profile
near flat; propodeum on distinctly lower plane, spines well
developed, upturned and triangular. Postpetiole with a flattened
profile.
In Nigeria, collected from leaf litter and from under a
chip of wood at CRIN (B. Bolton). |
