The 9 of the sp., previously known only from the 6 holotype from Ecuador, is described (allotype 9: Peru, Loreto Dept., 80 km NE Iquitos, 28-VIII-I989; deposited at FSCA, Gainesville, FL, USA). It is similar to A. robusta Belle, but has the pale lateral stripes of the thorax wider than the intervening dark stripes, black tibiae, and oblong lobes on the subgenital plate. A. rohusta 9 has dark stripes widest, red-brown tibiae, and rounded subgenital lobes.
