Diagnosis. Anopinella isodelta is most similar to A. triquetra . It can be distinguished by the broader dorsum of the tegumen, shorter socii, more spinose lateral edge of the distal lobes of the gnathos, more evenly upcurved costa of the valva with a narrower “neck” portion, and slightly more anterior origin of the accessory bursae.

Redescription. Head: Frontoclypeus, vertex, and labial palpus white. Antenna with scape brown intermixed with pale brown; basal 8­10 flagellomeres brown; distal flagellomeres gray.

Thorax: Tegula and mesonotum white intermixed with brown. Forewing (Fig. 56) length 8.2­9.3 mm (n = 3); incomplete basal fascia pale reddish brown intermixed with olive green, or white intermixed with reddish brown and pale brown; costal blotch obtriangular, brown intermixed with dark brown on posterior end; basal fascia and costal blotch separated by a pale, oblique band of white intermixed with pale reddish brown and pale brown demarcating costal blotch, recurved from distal costa through subapical area to tornus, encircling an elliptical ocellus, except on posterior end; ocellus brown or faint; if faint, distal ca. 0.33 nearly white; costal blotch with a small, subcircular, white spot near posterior end; area between CuP and posterior margin pale reddish brown intermixed with pale brown and brown, or white intermixed with pale reddish brown and pale brown; apical and subapical areas white intermixed with brown. Fringe with inner portion brown, outer portion reddish brown. Hindwing grayish white, with several irregular transverse gray bands.

Abdomen: Male genitalia ( Fig. 1 ; drawn from BMNH slide 6315; n = 1) with uncus curved near apical 0.33. Socius short, ca. 0.14 length of gnathos arms, not extending beyond base of gnathos. Gnathos arms enlarged distally forming two laterally flattened lobes, each with an irregularly serrate outer margin; lobes fused dorsally. Valva with a densely setose cucullus and basal ridge; costa nearly straight from subbasal curve, slightly arched dorsally in apical 0.2; ventral margin of valva broadly curved in basal 0.66, slightly recurved at apicoventral angle; outer margin convexly rounded. Phallus short; vesica densely microtrichiate. Female genitalia ( Fig. 34 , drawn from BMNH slide 23472; n = 2) with sclerotized mesal patch at lamella postvaginalis slightly longer than wide; eighth tergum not modified; ostium broadly U­shaped, less than 0.5 width of seventh sternum at widest point. Ductus bursae long, slender; inception of accessory bursae ca. 0.8 distance from ostium to corpus bursae. Corpus bursae subcircular, densely spiculate on ca. 0.14 side bearing ductus seminalis.

Lectotype, ɗ (designated by Clarke 1958), Colombia, San Antonio, 5800' [1785 m], Nov 1907, 6 /1. Deposited in BMNH.

Paralectotype (1Ψ). COLOMBIA: San Antonio, 5800' [1785 m], Nov 1907, 6 /3 (BMNH) [head missing].

Additional Specimen Examined. COLOMBIA: San Antonio, 5800' [1785 m], Nov 1907 (1Ψ), 6/6 (BMNH).

Remarks. In his original description, Meyrick (1912) indicated that he had two specimens (1ɗ, 1Ψ); Clarke (1958) designated the male as the lectotype. We found a third specimen (Ψ) in BMNH with identical data as the original pair. Because the lectotype is labeled “6/1,” the paralectotype “6/3,” and the additional specimen “6/6,” there must have been 6 specimens in the Meyrick Collection identified as “ Eulia isodelta ” even though he mentioned only two in his description.
