Loboponera subatra

Specimens have been collected from rainforest litter.

Identification
Bolton & Brown (2002) - A member of the vigilans species group. This relatively large, slender species is recognized by the lateral blunt tooth on each side of the anteromedian process of the first gastral sternite. In Loboponera vigilans there is usually an angular development in the same place, but the latter species has characteristic sculpture and has a median carina on the first gastral sternite, which is completely absent in subatra.

Distribution based on Regional Taxon Lists
Afrotropical Region: Cameroun, Central African Republic.

Worker
Holotype. TL 7.3, HL 1.32, HW 1.11, CI 84, SL 1.27, SI 114, AL 2.38. Characters of vigilans group and the following. Maximum diameter of eye 0.10. First gastral sternite without trace of a median longitudinal carina. Anteroventral median process of first gastral sternite with an anteriorly directed blunt tooth on each side that also arises from the sternite. Propodeal declivity with a broad triangular tooth near base, the margin above this with a small rounded tubercle; dorsum of alitrunk rounds into declivity. Short pilosity very dense on all dorsal surfaces, also dense on scapes, femora and tibiae. Dorsum of head and alitrunk predominantly longitudinally costaterugose, the alitrunk also with foveolae but most of these are partially effaced by the longitudinal component; foveolae are most clearly defined on propodeum. Second gastal tergite longitudinally costate-rugose, the sculpture better defined here than on the first tergite, where the foveolate component is more obvious.
