Diagnosis. In forewing pattern and color, A. powelli is similar to A. triquetra , A. porrasa , and A. cartagoa , but it is a slightly smaller species. The single known male is assigned to the species provisionally. The most conspicuous autapomorphies for A. powelli are the large, deep, rounded antrum and the narrow, sclerotized line across the dorsum of the eighth tergum ( Fig. 38 ).

Description. Head: Frontoclypeus and vertex pale brown or pale brown intermixed with few brown scales; labial palpus with outer surface brown intermixed with pale brown, inner surface pale brown. Antenna with scape brown intermixed with pale brown; basal 8­ 10 flagellomeres brown; distal flagellomeres gray.

Thorax: Tegula and mesonotum brown intermixed with pale brown. Forewing (Fig. 62) length 6.5­7.9 mm (n = 6); incomplete basal fascia pale brown or brown intermixed with yellowish brown and reddish brown; costal blotch pale brown or brown intermixed with dark brown and reddish brown on posterior half; basal fascia and costal blotch separated by an oblique, pale band of white intermixed with pale brown and/or pale yellowish brown demarcating anterior part of basal fascia and costal blotch to slightly beyond CuP; recurved band wide from distal costa through subapical area to tornus, completely encircling an elongate ocellus; ocellus pale gray or brown, acuminate, widened to posterior end; area between CuP and posterior margin dark brown intermixed with pale brown, or pale reddish brown intermixed with brown; costal blotch with a subrectangular or subcircular white spot near posterior end; apical area brown; submarginal area narrow, with alternating dark brown and reddish brown patches. Fringe alternating reddish brown and gray. Hindwing pale grayish brown.

Abdomen: Male genitalia ( Fig. 14 ; drawn from DA slide 4227; n = 1) with uncus curved at ca. 0.5 length. Socius slightly widened, digitate, ca. 0.75 length of basal portion of gnathos arms. Gnathos arms abruptly widened distally, forming two elongate (as long as basal portion of gnathos arms), semicircular, laterally flattened lobes with sparsely serrate margins. Valva with ventral margin weakly undulate from base to apicoventral angle, slightly produced immediately before apicoventral angle; densely setose from cucullus to apicoventral angle and from basal ridge to postsaccular area; costa conspicuously sloped dorsally at cucullus; cucullus slightly rounded apically, outer margin broadly rounded to apicoventral angle. Phallus simple; vesica sparsely microtrichiate. Female genitalia ( Fig. 38 ; drawn from JWB slide 1072; n = 6) with broad, weakly developed sclerotized mesal patch at lamella postvaginalis; eighth tergum with lateral sclerotized line across dorsum ( Fig. 38 insert); ostium widely U­shaped, less than 0.5 width of seventh sternum at widest point. Antrum a deep, broadly rounded bowl; ductus bursae long, slender; inception of accessory bursae ca. 0.65 distance from ostium to corpus bursae. Corpus bursae subcircular, densely spiculate on ca. 0.25 side bearing ductus seminalis.

Pupa. Typically tortricinae, without modification of head; no conspicuous sculpturing. Abdominal segments 3­8 with two rows of spines dorsally. Cremaster short, stout, with 6 long hooked setae. Indistinguishable from that of A. styraxivora ( Figs. 91, 92 ).

Biology. According to label data, a specimen from Monteverde was reared from a fungus gall on Inga longispina (Fabaceae) . With one exception, all specimens examined were collected from March through May.

Etymology. The species epithet honors Jerry A. Powell who led the charge of collecting microlepidoptera in Mexico and Costa Rica .

Remarks. As mentioned above, the association of the sexes is equivocal. The forewings of the male specimen are in extremely poor condition, so a comparison of pattern elements is impossible. However, the specimen is about the right size (i.e., forewing length) and was collected at the same locality as two of the female paratypes (i.e., Finca Cafrosa). Below we describe another species from Finca Cafrosa ( A. cafrosana ), but males of that species have a conspicuously shorter, more rounded outer margin of the valva between the apicoventral angle and the apex of the costa ( Fig. 14 ).
