Costa Rica, Heredia, 11 km ESE La Virgen , 450–550 m, 10°20’N 84°04’W, INBio-OET Transect, 23 . ii.2003, 2 males, fn, 05/TN/04/004, 05/TN/02/002; 18. iii.2003, 1 female, fn 05/UF/03/09; 23. iii.2003, 1 female, bad condition, fn 05/TN/16/018 ( INBio). All specimens in alcohol.

Remark. Some of the diagnosic characters proposed by Otte (2006) are not congruent with the type pictures (Otte 2006, Fig. 10) and the observation of additional specimens from the same locality. The main characters of the species are given below, including the characters of male genitalia, coloration and size, not described until now.

Emended diagnosis. In addition to the characters of the genus ( Desutter-Grandcolas 1993): Body dark brown; head dorsum brown; scape, antennae and maxillary palpi light yellow, palpi joint 5 perhaps darker (character indistinct in specimens at hand kept in alcohol: Fig. 4 B); DD light orange to ochre, including anterior and posterior margins ( Fig. 4 A); LL dark brown; mesonotum ochre, bordered with brown distally; legs light yellow, knees darker; sternites yellowish, subgenital plate darker. Male genitalia more similar to A. septentrion n. sp.: pseudepiphallic process flat and long, slightly raised before apex ( Fig. 4 F), not bilobate but somewhat emarginate on distal margin ( Fig. 4 D, E); anterior margin of pseudepiphallic sclerite strongly sclerotized ( Fig. 4 D).

Pseudepiphallic parameres vertical, only lightly sclerotized. Female. Subgenital plate much wider than long, apically indented. Ovipositor very short (see measurements), the dorsal valves slightly denticulate apically. Measurements (in mm).
