Diagnosis. Anopinella tinalandana is one of the smallest species in the genus. The male genitalia are most similar to those of A. choko , A. cuzco , and A. brasiliana in the possession of a large, bent uncus; moderately long socii; a gnathos typical of the Fana Species Group; and small spines from the venter of the valva in the vicinity of the apicoventral angle. The female genitalia differ from those of A. brasiliana in the origin of the accessory bursa near the middle of the ductus bursae rather than near the junction of the corpus bursae and ductus bursae, as is the case in the latter. Female genitalia are not known for either A. choko or A. cuzco . Putative autapomorphies for A. tinalandana include the outer margin of the cucullus broadly rounded from the apicoventral angle to the apex of the costa, forming a diagonally elongate cucullus; and the broadly cup­shaped antrum.

Description. Head: Frontoclypeus white, vertex white intermixed with brown; labial palpus with outer surface white intermixed with brown, inner surface white. Antenna with scape brown or reddish brown intermixed with pale brown; flagellomeres grayish brown.

Thorax: Tegula and mesonotum pale yellowish brown, intermixed with reddish brown. Forewing (Fig. 84) length 6.0­ 7.5 mm (mean = 6.8 mm; n = 4); basal fascia and costal blotch brown, intermixed with reddish brown and grayish brown, separated by a pale band of white, intermixed with some reddish brown scales demarcating a subtriangular costal blotch, recurved from distal costa through subapical area to tornus, encircling an elliptical ocellus, except posterior end; band narrowed proximodistally; costal blotch with a small white spot near posterior end; area between CuP and posterior margin brown intermixed with gray, pale reddish brown, and white; apical and submarginal areas brown intermixed with reddish brown. Fringe gray or reddish brown, inner portion with scales tipped with white in some specimens. Hindwing pale gray, slightly darkening to apex.

Abdomen: Male genitalia ( Fig. 18 ; drawn from USNM slide 82077; n = 1) with uncus bent at ca. 0.33 distance from base, slightly upcurved in distal portion. Socius digitate, ca. 0.33 length of gnathos arms. Gnathos arms free distally, each arm dorsally expanded forming a large rounded lobe; lobes narrowed distally into a dorsoventrally flattened, digitate process. Valva comparatively short, setose from cucullus to basal ridge; costa arched dorsally from subbasal curve to apex; sacculus and postsacculus nearly straight, with only faint concavity at postsacculus; outer margin of cucullus broadly rounded from apicoventral angle to apex, forming a diagonally elongate cucullus. Phallobase slightly broadened basally; vesica densely microtrichiate. Female genitalia ( Fig. 52 ; drawn from DA slide 4217; n = 2) with vase­shaped sclerotized mesal patch at lamella postvaginalis; eighth tergum not modified; ostium broadly U­shaped, ca. 0.5 width of seventh sternum at widest point. Antrum cup­shaped; ductus bursae long, slender; inception of accessory bursa ca. 0.6 distance from ostium to corpus. Corpus bursae large, subspherical, spiculate on 0.17 side bearing ductus seminalis.

Etymology. The species name is derived from the type locality, Tinalandia, Ecuador.

Remarks. Although we would have preferred to designate the male paratype as the holotype, its association with the small series of females from Tinalandia is equivocal, and the unspread specimen is in considerably poorer condition than the holotype female.
