Specimen Label

Only known from a few collections, specimens labels indicate individuals were captured by winkler sampling of leaf litter from primary forest. Nothing else is known about the biology of Hypoponera aprora.

Identification

Bolton and Fisher (2011) - This species is immediately distinguished from all its Afrotropical and West Palaearctic congeners by its lack of the prora on the first gastral sternite, both laterally and anteroventrally. It belongs in the occidentalis complex of the abeillei group, notes on the species of which are given under occidentalis. See also under Hypoponera dis, which appears to be its closest relative.

Biology

Hypoponera inhabit and nest in leaf litter, the surface layer of soil, downed rotten wood, and soil around plant roots. Nests are typically found by turning objects on the ground, like downed wood and rocks, or through the ripping away of bark found on rotting downed wood or at the base of dead trees. Litter samples in tropical areas, especially in moist forested sites, often contain individuals of this genus. All Hypoponera are thought to be predators of small arthropods but published details about their diet are sparse. A lack of information about other aspects of their biology is also typical for most species.

The genus is most diverse in the tropics. Species found in higher latitudes tend to be more widespread, common and abundant than their tropical and subtropical congeners.

Castes

Known only from the type specimens. Workers and a queen have been collected but the queen was not described.

Description

Worker

(holotype in parentheses). Measurements: HL 0.51–0.53 (0.51), HW 0.40–0.41 (0.40), HS 0.455–0.470 (0.455), SL 0.34–0.36 (0.34), PrW 0.30–0.32 (0.31), WL 0.65–0.68 (0.66), HFL 0.34–0.35 (0.34), PeNL 0.15–0.16 (0.15), PeH 0.30–0.32 (0.31), PeNW 0.26–0.27 (0.26), PeS 0.240–0.250 (0.240) (8 measured). Indices: CI 77–79 (78), SI 83–88 (85), PeNI 84–87 (84), LPeI 49–53 (49), DPeI 163–173 (173).

Conforming to the general description given for dis but lacking a prora. In aprora, with the first gastral seg-ment in profile, the anterior and lateral surfaces of first gastral sternite meet in a blunt angle; there is no prominent raised proral crest or rim separating the two surfaces below the level of the helcium. Similarly, there is no trans-verse raised margin or lip separating the anterior and ventral surfaces of the first sternite. Full adult colour glossy dark brown to blackish brown.
