Oecophylla longinoda variety fusca (Emery)


Oecophylla longinoda variety fusca (Emery)  HNS 

Worker differing from rubriceps  HNS  only in having the head entirely black or dark brown, though sometimes with a reddish tinge above. Mandibles black, with dark brown teeth. Large workers have the clypeal border very feebly sinuate in the middle and the surface just behind it with a faint longitudinal impression. The smallest workers are a little paler, with paler mandibles, but in the structure of the thorax and petiole precisely like the corresponding phase of the other forms of the species.

Female like that of rubriceps  HNS  , but perhaps a shade darker.

Male indistinguishable from the male of rubriceps  HNS  , except that the erect white hairs on the dorsal surface of the head, thorax, and gaster are distinctly longer and more abundant.

Redescribed from specimens taken at Stanleyville and Garamba (Lang and Chapin). There is also a worker of this variety from Monrovia, Liberia, (J. Morris) in my collection.
