Diagnosis. The male genitalia of A. styraxivora are unlike those of all other species of Anopinella , with the distal lobes of the gnathos medially fused, forming a dorsoventrally flattened, spinose plate, and the valva narrow and lanceolate, with a large postsaccular lobe bearing a cluster of large spinelike setae. Autapomorphies for the species include these unique features of the male genitalia, plus the shiny forewing scaling. The highly divergent morphology of this species suggests that separate generic status may be justified if and when additional species are discovered to validate these synapomorphies.

Description. Head: Frontoclypeus and vertex white; labial palpus with outer surface white intermixed with few brown scales, inner surface white. Antenna with scape white intermixed with few brown scales; basal 6­8 flagellomeres brown; distal flagellomeres brownish gray.

Thorax: Tegula and mesonotum white intermixed with pale yellowish brown and some brown scales. Forewing ( Fig. 72 ) length 6.0­ 8.1 mm (n = 2); incomplete basal fascia and costal blotch grayish brown intermixed with brown, reddish brown, and white; separated by a pale narrow white band demarcating costal blotch; costal blotch subtriangular, extending to distal costa, with typical small white spot near posterior end absent; area between CuP and posterior margin pale gray intermixed with few reddish brown scales; area beyond costal blotch pale gray intermixed with white. Fringe with inner portion reddish brown, outer portion gray. Hindwing pale brown basally, gradually darkening to apex.

Abdomen: Male genitalia ( Fig. 33; drawn from JWB slide 557; n = 1) with uncus curved at ca. mid­length. Socius digitate, short, ca. 0.16 length of basal portion of gnathos arms. Gnathos arms fused distally, forming a multispinose, horizontal plate. Valva widest basally, gradually narrowed toward apex; costa straight throughout length, densely setose apically; postsaccular margin abruptly rounded distally forming an subtriangular lobe bearing a dense cluster of stout setae; cucullus elongate, knife­like. Phallus slightly curved medially; vesica densely microtrichiate, with two elongate cornuti. Female genitalia ( Fig. 55 ; drawn from JWB slide 558; n =1) with broadened sclerotized mesal patch at lamella postvaginalis; eighth tergum with a median longitudinal sinus; ostium wide, ca. 0.33 width of seventh sternum at widest point; ductus bursae long, slender, gradually widened anteriorly; inception of accessory bursae ca. halfway between ostium and corpus bursae. Corpus bursae large, subspherical, weakly spiculate on 0.65 side bearing ductus seminalis.

Pupa ( Figs. 91, 92 ). 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. powelli .

Holotype, ɗ, Costa Rica , Heredia Province, Uvita de San Rafael, 1700 m, 10 Mar 1991, P. Hansen, r.f. Styrax fruit [pupal exuvium pinned with specimen]. Deposited in UCB.

Paratype (1Ψ). COSTA RICA : Heredia Province: Uvita de San Rafael, 1700 m, 10 Mar 1991, P. Hansen, r.f. Styrax fruit. Deposited in USNM.

Biology. According to label data, both the holotype and paratype were reared from the fruit of Styrax (Styracaceae) .

Etymology. The specific epithet is derived from the host plant genus Styrax , combined with the Latin “ivora.”
