Hypoponera cognata (Santschi)

return to key {link to the Hymenoptera Name Server} Type location Angola (Ponera ergatandria Forel stirps cognata n. st., Santschi, 1912b: 153, worker; queen; raised to species Bernard, 1952: 202, illustrated, queen) from Benguela; worker and queen described (new combination in Hypoponera, in Bolton, 1995) .

{Hypoponera cognata}Santschi's (1912b) description is at {original description}. Arnold (1915: 81) gave a translation (under Ponera ergatandria r. cognata), this is at {original description}. Forel's (1893g) description of ergatandria, from the West Indies, is at {original description}.

WORKER (after Bernard, 1952) - TL 2.5-3.0 mm; head brown, shiny; body dark red, gaster darker, tarsi yellow. Head with sides parallel, vertex slightly concave; eyes 3-5 facets; mandibles with 6 spaced out teeth, 3 long then 3 short. In profile declivity of propodeum similar length to dorsum.

I suspect that the specimens determined as Ponera ergatandria by Santschi (1914b) from Kenya (Shimoni, Alluaud & Jeannel) and also listed by Wheeler (1922: 781) from South Africa (Natal, Durban by H Bell-Marley), are this species.

Wheeler (1922) has it, as a subspecies of Ponera ergatandria (a tropicopolitan species first described from West Indies), and lists it from Angola (Benguela) and Zimbabwe (Bulawayo); he had Hypoponera petri as another subspecies.

From Africa, including Guinea, noted as common by Bernard (1952) but the specimens were somewhat more slender, smoother and with less pubescence than the types known from south-central Africa (Zimbabwe, Angola). He felt this did not warrant designating the Nimba form as a separate variety. Recorded specimens were from Mount Tô forest, B 2-41, ravine 1 (Lamotte, 1 queen, 1 worker). Found also at Banco, Ivory Coast (Delamare-Debouteville).
