Crematogaster (Atopogyne) kohli Forel

return to key {link to the Hymenoptera Name Server}Type location Zare (Cremastogaster Kohli n. sp., Forel, 1909b: 70, worker, not illustrated; Forel, 1915c: 340, queen) from Kisangani [Stanleyville], by Kohl - see below

Worker and queen described (see Bolton, 1995) .

Note (August 2016): I have removed all the former "subspecies" to under Crematogaster (Atopogyne) winkleri.

Forel's (1909b, 1915c) description is at {original description}.
My translation of the type is -
WORKER - TL 2.5-2.7 mm; very similar to Crematogaster inconspicua Mayr (in subgenus Crematogaster) in having [my interpretation] a mid-thorax depression [I suspect as shown in Crematogaster depressa]; also the postpetiole is deeply incised posteriorly, but without an anterior notch. In contrast, kohli is shorter and stockier; the scapes do not reach the posterior quarter of the head; the flat mesonotum has an anterior median longitudinal prominence (the mesonotum is convex and without a carina in inconspicua). Propodeal spines as long as the basal interval and quite sharp. Head impressed behind, wider than long. Similar in the first instance to africana but differing mainly in the depressed thorax which resembles that of inconspicua.
Shiny, very finely and feebly shagreened, with sparse puncturations; thorax less shining, because of very fine longitudinal striae.
Almost no erect hairs. Pubescence fairly weak, more on tibiae and scapes which lack erect hairs.
Very black; legs and scapes dark brown; mandible, funiculi and tarsi dark red brown.
FEMALE - TL 6.7 mm; scutellum prominent; propodeum subvertical, high, with spines about as long as the inter-basal space; sculpturation of head more feeble than worker, with occiput quite shiny. In that, similar to foraminiceps, prompting the question of how valid is the separation? The sparse hair pits are stronger and more abundant between the fine striations.
Specimens from Kisangani [Stanleyville] by Kohl; later also from St. Gabriel, by Kohl from carton nests, 10-20 cm in size, on larger trees.
