Anopinella transecta Brown and Adamski, new species

Figs. 15, 42, 60

Diagnosis. Anopinella transecta is a moderately small species with a well defined forewing pattern. The male genitalia are similar to those of A. triquetra with a long angled outer margin of the valva. They can be distinguished from all other congeners by the subapical lateral flanges of the gnathos arms, which appear to represent an autapomorphy for the species. The female genitalia likewise are similar to A. triquetra, with a pair weakly developed oblique ridges on the dorsum of the eighth tergum.

Description. Head: Frontoclypeus white intermixed with brown, vertex pale yellow intermixed with dark gray; labial palpus with outer surface brown intermixed with reddish brown, inner surface white. Antenna with scape brown intermixed with dark brown; basal 8­10 flagellomeres reddish brown intermixed with brown; distal flagellomeres gray.

Thorax: Tegula and mesonotum pale reddish brown intermixed with pale yellow and gray. Forewing (Fig. 60) length 5.9­6.2 mm (n = 3); incomplete basal fascia and costal blotch brown intermixed with some orange­brown and dark brown, separated by an oblique pale band of white intermixed with pale reddish brown demarcating a costal blotch to slightly beyond CuP, recurved from distal costa through subapical area to tornus, encircling an elliptical ocellus, except for posterior end; costal blotch subtriangular, with a small, subcircular, white spot near posterior end; area between CuP and posterior margin brown intermixed with reddish brown and white; apical and submarginal areas brown intermixed with orange brown. Fringe mostly white intermixed with some grayish. Hindwing dark gray.

Abdomen: Male genitalia (Fig. 15; drawn from DA slide 4745; n = 1) with uncus curved near apical 0.33. Socius digitate, ca. 0.5 length of basal portion of gnathos arms. Gnathos arms with a broad lateral flange subdistally, arms curved apically, forming a pair of dorsally fused, narrow lobes with a weakly serrate margin. Valva narrow, gradually expanded subdistally, densely setose from outer margin of cucullus to basal ridge; outer margin nearly straight in ventral 0.6, then curved to apex of valva; apicoventral angle slightly protuberant. Phallus simple, relatively short, stout; vesica slightly microtrichiate. Female genitalia (Fig. 42; drawn from DA slide 4562; n = 2) with a weakly developed, rectangular sclerite at lamella postvaginalis; eighth tergum with a pair of weak oblique ridges converging posteriorly (Fig. 42 insert); ostium weakly U­shaped, less than 0.5 width of seventh sternum at widest point. Ductus bursae long, slender; inception of accessory bursa ca. 0.8 distance from ostium to corpus bursae. Corpus bursae large, subspherical, spiculate on 0.33 side bearing ductus seminalis.

Etymology. The species name refers to the ALAS transect at ca. 1070 m where the holotype was collected. ALAS is the acronym of the NSF­funded project known as the Arthropods of La Selva.

Remarks. The association of the sexes is equivocal since females were collected a considerable distance form the type locality, and is based primarily on forewing length and pattern.
