[16] A. chirichinii ^HNS

and A. fricatus ^HNS are very close species, but the differences described by Wilson (1959) appear to hold in the material available, which is the same he had. The two species are sympatric in NE New Guinea, but fricatus ^HNS was found additionally at Brown River, near Karema, Papua. The male terminalia labeled as A. chirichinii ^HNS are those of a male taken at light at Nadzab, NE New Guinea, a locality at which Wilson took workers of both species. The male is the right size to be either species, and could even belong to some other species from this locality remaining uncollected. At any rate, the determination of this male must be considered uncertain.
