Hypoponera transvaalensis (Arnold) View in CoL HNS
Ponera transvaalensis Arnold HNS , 1947: 132, fig. 2. Holotype worker, SOUTH AFRICA: Transvaal, Mariepskop (J.C. Faure) (SAMC) [not seen]. [Combination in Hypoponera HNS : Bolton, 1995: 216.]
WORKER. Measurements: HL 0.88, HW 0.74, HS 0.810, SL 0.70, PrW 0.56, WL 1.26, HFL 0.70, PeNL 0.26, PeH 0.58, PeNW 0.40, PeS 0.413. Indices: CI 84, SI 95, PeNI 71, LPeI 45, DPeI 154.
A large, darkly coloured species, very closely related to sulcatinasis HNS and answering the general description of that species, but differing as follows.
1 Dorsum of propodeum weakly sculptured anteriorly; the sculpture fades out posteriorly so that the posterior half is almost smooth. In sulcatinasis HNS the entire propodeal dorsum is uniformly reticulate-punctate.
2 Propodeum without a sharply defined boundary between dorsum and declivity that is brought about by an abrupt loss of sculpture. In sulcatinasis HNS the boundary between propodeal dorsum and declivity is strongly demarcated by the abrupt disappearance of sculpture at the junction of dorsum and declivity.
3 Punctate sculpture of pronotal and mesonotal dorsa weak and superficial; punctures very small and widely separated. In sulcatinasis HNS the punctures on the pronotal and mesonotal dorsa are dense, sharply incised and conspicuous.
4 Metanotal groove with weakly defined anterior and posterior sutures, so that a narrow metanotal sclerite is present on the mesosomal dorsum. In sulcatinasis HNS merely a groove is present.
It seems probable that sulcatinasis HNS and transvaalensis HNS may eventually prove to be nothing more than two geographical variants of a single species. But because the little material available can be separated by the characters given above, they are maintained as separate for the present.
Material examined. South Africa: Transvaal, Pilgrim’s Rest, Mt Sheba Forest (S. Zoia).
