Adelomyrmex HNS

Basal border of mandibles with a tooth at or proximal to the midlength of the border.

Maxillary palp 1 - segmented (Gotwald, 1969).

Median portion of clypeus swept upwards into a strongly raised sharp-edged longitudinal platform which projects sharply forwards into a lobe; anterior clypeal margin sweeping downwards and outwards away from and behind the apex of this lobe.

Hairs present on dorsal surfaces of head and body.

Postpetiole not short-cylindrical in dorsal view, usually without a truncated ventral process.

Petiole usually high and narrow in profile, only rarely low.

Metapleural lobes small, separated from the propodeal spines above.

Range: Neotropics, New Guinea, Fiji, Samoa.

Among the Myrmicinae HNS of the Ethiopian zoogeographical region Baracidris HNS is unique in possessing 12 - segmented antennae with a 2 - segmented club. This character, coupled with the very closely approximated frontal lobes with the median clypeus narrowly inserted between them, the short 5 - dentate mandibles, reduced palp formula of 2, 2 and the shape of the pedicel segments, renders Baracidris HNS quickly recognizable. The key presented below will separate the myrmicine genera of the region which have a conspicuously 2 - segmented antennal club. Crematogaster HNS is included as a few species have such a club although the vast majority of species in this genus have the club 3 - segmented.
