Crematogaster (Crematogaster) cavinota Santschi - new status

return to key {link to the Hymenoptera Name Server} Type location Central Africa Republic (Cremastogaster excisa Mayr r. cavinota n. stirps, Stitz, 1916: 385, illustrated, worker) from between Fort de Possel and Fort Crampel, by Schubotz (not "Congo" as given in Bolton, 1995) - see below
junior synonym (here) bomaella (Crematogaster (Acrocoelia) excisa Mayr stirps bomaella n. var., Santschi, 1935a: 258, see below) from Zare, Boma, collected by Dr R. Schouteden, 8.ix.1920 - see below

My translation of Santschi (1935a):
WORKER - TL 2.6-3.2 mm. Overall red brown; funiculus (other than the club), joints of legs and gaster (other than darker apex) clearer yellow brown. Head shiny and smooth, except for the genae, which have fine longitudinal striations. Thorax matt, finely reticulo-punctate with irregular elongated and anastomosed striations, stronger in large specimens. Sides of thorax with fine reticulation giving the appearance of longitudinal striae; sculpturation intermediate between excisa and andrei. Gaster smooth; with some erect translucent hairs, more numerous apically. Pilosity fine and spaced out on body and appendages. Head slightly larger than excisa, sides arcuate but with more convex, larger eyes. Clypeus smooth, almost flat and without a carina; anterior border as excisa in being slightly arcuate. Post-clypeal notch shallow (very marked in euphrosyne - a variety now excluded by Bolton, 1995). Scape reaching occipitum; funiculus segments 2-7 short, no longer than wide; club thick, with last segment slightly longer than wide. Pronotum laterally bordered, dorsal face flat (as excisa).
Mesonotum as wide as long, sides bordered with a sharp declivity posteriorly and lightly carinated anteriorly. Propodeal spines divergent, as long as the propodeal dorsum, seen from above the space between the bases is rectilinear, the points of the spines slightly farther apart than the width of the pronotum. Petiole as wide as long, anterior angles rounded, sides feebly roughened. Postpetiole deeply incised. Overall resembling impressa ssp brazzae Sants. but smaller and clearer, thorax more sculptured and propodeal spines more divergent; clypeus less convex. Differs from menilekii (as satanula) by the much finer sculpturation and shorter propodeal spines.
