Monomorium yemene

The non-type collection of this ant, one of only two locations where it has been found, was taken from the flowers of an Adenium species.

Identification
Collingwood and Agosti (1996) - Bolton (1987) noted this species without naming it as being similar to Monomorium hirsutum from Ethiopia but pointed out differences in the shape of the alitrunk and the presence of abundant erect pubescent hairs on all appendage surfaces including the antennae. The eyes are small, 0.19-0.20 times HW as in M. hirsutum, but the unusual long erect pubescence distinguishes M. yemene from all other species within this complex.
