return to key {link to the Hymenoptera Name Server} Type location Senegal, Wassa, Tambacounda; 1306'30"N 1205'18" W; 4.v.2009; Wassa 04-V-09 St 1 P11F;
Soudanian savannah, pitfall traps; collector B Ndiaye. Six workers


WORKER - TL ca 8.0 mm, HL 1.6, HW 1.6, SL 1.6, PW 1.05, CI 100, SI 100; particularly distinctive is the smooth clypeus with no more than the faintest trace of carinae; segment 2 of funiculus is the same length as segment 3 (the Santschi, 1925c, key stops at couplet 9); very long mesokatepisternal tooth; posterior of mesonotum drops almost vertically into a deep metanotal groove from a raised prominence; propodeal spines long and straight, bases of spines seen from above close together, propodeum profile flat; petiole node domed in profile, higher than long; postpetiole slightly lower also domed; head with longitudinal striations on front and laterally; alitrunk dorsum with well defined median and lateral striations but otherwise dorsum of pronotum with relatively few, widely spaced coarse longitudinal striations; dorsum of petiole longitudinally striate; longitudinal striations on lateral alitrunk; gaster paler and wholly shiny; anterior margin of clypeus with fringe of 16-18 moderately long fine hairs; whole body with numerous but quite short erect hairs, propodeum with several erect hairs, on the gaster there is a mixture of short and shorter semidecumbent hairs.

This appears close to Myrmicaria distincta but this has longer hairs all over. and distincta has no more than a pair of erect hairs on the propodeum M. distincta does not have the same strong longitudinal striations on the alitrunk but has more on the dorsum; this has a larger propodeal spiracle. The longitudinal striations on the front of the head on distincta markedly curve outwards towards on this they remain straight.  This has smooth mandibles, on distincta they are striate. This has a shiny smooth gaster, on distincta the gaster has distinct microspiculation making it appear dullish. The scapes are dark contrasting with the head; in distincta they are unicolorous with the head.
