Worker measurements (n=1). HL 0.61 HW 0.50 SL 0.35 EL 0.06 WL 0.58 GL 0.72 TL 2.36 CI 82 SI 70.

Worker diagnosis. The last antennal flagellomere large, nearly as long as the remainder of antennal funiculus. Eyes reduced to dark spots. Metanotal groove slighty impressed. Propodeal spiracle round and small. Dorsal surface of propodeum shorter than declivituous face, with two very short and triangular spines. Propodeal lobe subtriangular, slightly pointed. Protibiae swollen near apex. Head, mesosoma, petiole and postpetiole smooth and shining, puncturated, punctures more or less closed. Longitudinal midline of head without punctures. Most of declivitous face of propodeum smooth and shining with median keel joining the propodeal spines; most of lateral sides of thorax smooth and shining with spaced punctures; meso and metapleuron longitudinally rugose; petiolar sculpture similar to head. Body light brown, legs yellowish brown; abundant median whitish pilosity on head dorsum, scapes, thorax dorsum, petiole, postpetiole and gaster. Appressed pilosity on funiculus. Shorter and reclinated pilosity on legs.

Material examined: FIJI, holotype worker, W.M. Mann ( USNM) .

Comments. A. hirsutus can be separated from A. samoanus by eye condition (they are reduced to dark spots); mesosoma outline, as seen in side view; and head sculpturing (punctate in hirsutus , punctate striate in samoanus ).
