Hypoponera lotti (Weber)

return to key {link to the Hymenoptera Name Server} Type location South Sudan (Ponera lotti, sp. nov., Weber, 1942: 45, illustrated, worker) collected in Lotti Forest by the author - no images on Antweb (January 2015); (new combination in Hypoponera Bolton, 1995) .

Bolton & Fisher (2011: 43) place it as a junior synonym of Hypoponera dulcis.

{Hypoponera lotti}Weber's (1942a) description is at {original description}.

WORKER (in part after Bernard, 1952) - TL 2.6 mm; colour brown; antennal scape surpassing the vertex of the head; eye of one facet, close to the mandibles, which have only feeble teeth. Clypeus margin with an obtuse central tooth; propodeum profile similar to that of Hypoponera dulcis.

Despite including it in his key to West African species, Bernard (1952) simply has "Soudan" as the location.

Bolton & Fisher (2011: 46) have: "there is some variation in the material examined that may suggest the presence of a second species within this group. In some darkly coloured specimens from Cameroun and Gabon (in BMNH and CASC), the mesonotum in profile is distinctly convex, whereas in all other material it is more or less flat. The degree of convexity varies and is sometimes difficult to assess as specimens in which the pronotum is fully flexed down with respect to the mesonotum appear more convex than those in which the two sclerites are aligned, because more of the curved anterior articulatory surface of the mesonotum is exposed. Coupled with this, the dorsum of the first gastral tergite in these workers where the mesonotum is more convex has conspicuous setae [hairs], whereas in the vast majority of specimens the setae on the first tergite are sparse and minute, and sometimes appear to be absent."  They appear to ignore what was written by Weber (1942a) and Bernard (1952).
