WORKER (Donisthorpe, 1945b) - TL 3-4 mm
Head a little longer than broad, posterior border excised centrally;
clypeus convex, anterior border rounded; frontal carinae narrow, flat
and divergent posteriorly; antennal scape not reaching posterior of
head; thorax rather short, contracted at metanotal junction, sides
rounded anteriorly; pronotum finely longitudinally striate and
punctate, punctures largest on sides, humeral angles rather prominent;
mesonotum flat, very finely longitudinally striate and punctate, striae
strongest on sides, with a strong carina from anterior margin to
declivity, metanotal groove wide and deep; propodeal spines stout,
short and sharp, projecting outwards; sides and dorsum striate;
postpetiole broader than long with slight impression posteriorly; first
segment of gaster finely punctate giving dull appearance; colour black,
somewhat shining, with short decumbent yellow hairs, plus some
outstanding long yellow hairs; antennal club and tarsi dirty yellow,
mandibular apex reddish .
My feeling prior to June 2015 was that this is no more
than a small
worker of Crematogaster
depressa - especially see the Cameroun workers on the linked
pages. The collection of five workers in Liberia (see below)
appears to confirm the validity of togoensis.
Notably different to depressa
is the almost uniform near black colour and the lack of erect pilosity
on the alitrunk.
