Tetramorium pusillum Emery variety hemisi
,
new variety
Worker. - Length 2.5 to 2.8 mm. Agreeing closely with Emery's description of the typical
pusillum
in size, sculpture, and coloration, but with the basal third or fourth of the first gastric segment densely punctate and nearly opaque, and with the epinotal teeth acute. The latter are distinctly larger than the metasternal teeth.
Described from fourteen workers taken from the stomach of a frog (Hemisus marmoratum) from Niangara (Lang and Chapin). The Abyssinian subspecies ghindanum Forel is slightly larger than this variety (at least this is true of several cotypes sent me by Prof. K. Escherich many years ago) and the opaque basal portion of the gaster is more extensive and finely striolate-punctate.
