(Figs. 16-20)

Material examined. Holotype ♂, Panama, Chiriqui, Totumas Cloud Forest, lodge, 08 ° 53.060’ N, 82 ° 41.068’ W, 1920 m, 19-25 June 2011, E. Fuller (USNM) . Paratypes: Costa Rica: Puntarenas, Rio Bellavista, ca. 1.5 km NW Las Alturas, 1400 m, 10-11 August 1990, R. Holzenthal, R. Blahnik, F. Munoz, 1♂ (BPSC) . San Jose, tributary Quebrada Caraiges, 3.6 km SW La Legua, 1650 m, R. Holzenthal, K. Kjer, F. Quesada, 2♂ (BPSC) .

Adult habitus. General color brown patterned with yellow-brown. Head with dark lappets, antennae and a dark band extends from behind ocelli forward to M-line; dark band expanded laterally along M-line, and interrupted by a pale interocellar spot (Fig. 16). Pronotum dark over most of disc, but with a slender pale median band. Wings pale brown, veins brown except for C and apical half of SC. Femora pale in proximal half and dark brown in distal half; fore and mid tibiae brown, hind tibiae with pale transverse median band.

Male. Forewing length 20 mm. Hammer a low, mound-like structure (Fig. 17). Aedeagal apex simple (Figs. 18-19); ventroapical aspect with a large pair of membranous lobes overlying darkly sclerotized lateral margins (Fig. 18); dorsal keel absent, lateral margins slightly convergent to truncate apex (Fig. 20). Hooks slender.

Female. Unknown.

Larva. Unknown.

Etymology. The species name, based on the type locality at the Mount Totumas Cloud Forest, is used as a noun in apposition.

Diagnosis. This species keys to couplet 11 in Stark (1998) where A. acutipennis Klapálek, 1923 and A. equisita, a pair of species with trilobed aedeagal apices are the options. Because the new species has a simple aedeagal apex without lateral lobes, neither of these choices are viable. The aedeagal apex of the new species is generally similar to that of A. varilla, a much smaller species (male FWL = 9-10 mm) known from Costa Rica and Panama (Stark 1998).
