status

new species

Anochetus estus   HNS , new species

Worker.- Length about 4.5 mm.

Closely related to A. africanus   HNS . Head, excluding the mandibles, a little longer than broad, the posterior margin deeply and arcuately excised. Eyes small, like those of africanus   HNS . Clypeus deeply emarginate in the middle, its posterior portion long and cuneate. Frontal groove distinct between the clypeus and the middle of the head. Mandibles about half as long as the head, shaped much as in africanus   HNS but with the terminal teeth shorter and the bases somewhat narrower. Antennal scapes not reaching to the posterior corners of the head; second funicular joint not longer than broad, third scarcely longer, joints 4 to 7 not twice as long as broad. In africanus   HNS all the funicular joints are much longer. Thorax shaped as in africanus   HNS , the pronotum rounded but not convex above, the mesoepinotum long, narrower and subcylindrical, with broad blunt epinotal teeth. The petiolar scale is high and compressed anteroposteriorly as in africanus   HNS , with feebly excised superior border, but the latter is more acute and the sides are nearly straight and subparallel (in africanus   HNS rounded). Gaster and legs of the usual type.

Shining; the upper surface of the head, except the impressions, sides and posterior corners subopaque and longitudinally rugulose, the rugules being regular and spreading fanwise from the frontal carinae. Thorax subopaque, the pronotum longitudinally and arcuately rugulose, except in front where the rugules are transverse, the meso- and epinotum transversely rugulose. The sculpture is distinctly finer than in africanus   HNS . Petiole and gaster very smooth and shining. Mandibles very indistinctly and finely punctate, smoother than in africanus   HNS .

Hairs slender, yellowish, erect, sparse on the body, absent on the appendages, which are very finely pubescent.

Deep castaneous brown, almost black, with the appendages, sides and posterior corners of head, mandibles, clypeus, and tip of gaster paler brown.

A single specimen from Akenge (Lang and Chapin) taken from the stomach of a toad (Bufo funereus).
