Hypoponera sinuosa (Bernard)

return to key {link to the Hymenoptera Name Server} Type location Guinea, (Ponera sinuosa n. sp., Bernard, 1952: 204, illustrated, worker & queen) from Mt. Nimba; holotype worker and one queen from, station B2-41, ravine I of the Mount Tô forest 21.ii.1942, collected by Lamotte.

Worker and queen described (new combination in Hypoponera, in Bolton, 1995) .

{Hypoponera sinuosa}WORKER (after Bernard, 1952) - TL 2.2 mm, HL 0.7, HW 0.6
Colour testaceous yellow, gaster darker except anteriorly; shiny, with little puncturation; fine whitish hairs. Head relatively short, sides sub-parallel, widest in anterior third. Eyes distinctive, 3-4 facets, black, very elongated, set some 1.5 times their length back from the mandibles (other "Ponera" have their eyes generally rounded and set some 6 times their length back from the mandibles). Vertex of head concave; antennal scapes not reaching the vertex. Clypeus smooth, almost flat, centrally with a feeble convexity but not carinate; anterior border rectilinear. Mandibles with 6 clear teeth, plus 4 small teeth. Propodeum, with its faces subequal, in profile declivity very sinuous - hence the species name; contrasting with other "Ponera" where the propodeum profile is more or less rectilinear.

Bernard (1952) emphasised how sinuosa by its pale shiny integument resembled the subgenus "Hypoponera" but nevertheless it has a well defined metanotal groove. The eyes and the propodeum set it apart from all other genus members in Africa.

Also known from Ivory Coast, cotype worker from Banco, H31, 30.vii.1945, Delamare-Debouteville (Bernard, 1952).
