This species ( Figs. 41, 42 ) is distinguished by the relatively small size, the dark hemelytra with a weak bluish sheen, the yellow to bright orange scutellum, the yellowish-brown to red-tinged head, and yellowish-brown pronotum, often with the calli tinged with red. It is most similar to A. barberi in overall coloration, but differs in the smaller size and the short, stout, apically rounded genital tubercle ( Fig. 128 ), whereas A. barberi is larger and has an elongate, apically acute genital tubercle ( Fig. 120 ).

Pronotum : Median length 0.67–0.78 mm ( 0.67 mm ); posterior width 1.38–1.54 mm ( 1.41 mm ). COLORATION. Head : Yellowish brown, sometimes weakly tinged with reddish orange; vertex with two transverse brown lines; frons with a wide row of transverse lines on either side of media line; clypeus dark brown to black.

Female: (n = 5): Length from apex of head to cuneal fracture 2.95–3.15 mm ; length from apex of head to apex of membrane 4.10–4.60 mm ; widest point across hemelytra 1.84–1.98 mm .
