Diagnosis. Enosis ester sp. nov. differs from all the other species of Enosis , except for E. angularis ( Möschler, 1877) , in not having a produced apex of the FW, and differs from E. angularis as well as all the others in having three small dark spots on the VHW. FW stigma with four parts between base of CuA 1 and 2A, whereas in E. angularis the stigma has two parts bellow bases of CuA 1 and CuA 2 (figs 11–12). The male genitalia also differ: uncus bifid; valva with ampulla of nearly the same size as harpe, harpe without ventral-distal short projection, sacculus not projected dorsally; aedeagus with insertion of manica at the end of basal third and bifid, while in E. angularis , uncus is simple; valva with ampulla larger than harpe, harpe with ventral-distal short projection, sacculus projected dorsally; and aedeagus, with insertion of manica at the beginning of the distal third and bifid (figs 13–14).

Male description. Head. Brown, frons and vertex covered with thin and long ochre scales. Eyes brown. Labial palpi (fig 4) densely covered with thin and long ochre scales on the proximal and middle article; proximal article short, rectangular in ventral view; middle article globose in lateral view, longer than wide in ventral view, about two times as long as the proximal; distal article covered with compact brown scales, short, about 1/3 the length of the middle article, and triangular in lateral and ventral views. Antenna brown, half the length of the FW costa; club longer than apiculus; nudum dark rufous to dark brown, 12–13 segments (n = 8).

Thorax. Brown dorsally, covered with long and thin hair-like scales; ventrally covered with long and thin lighter scales. Legs brown; mesotibia with a longitudinal row of short spines on inner surface and one pair of distal spurs, outer spur 2/3 the length of the inner; metatibia smooth, with two pairs of spurs, one at the middle of metatibia, other at the distal margin, outer spur 2/3 the length of the inner.

FW. Length 14–15 mm (male holotype with 15 mm; n = 8); triangular; costal margin straight; apex in a nearly right angle; outer margin convex; tornus obtuse; inner margin straight. DFW ground color brown; with two creamy spots in spaces R 5 -M 1, and M 3 -CuA 1; veins a little darker; stigma with four pieces, as in fig 11; fringe bicolor, proximal half of the scales brown, distal half creamy. VFW ground color brown, with the same creamy spots visible on DFW; veins more discernible than in DFW; fringe as in DFW.

HW. Costal margin convex; outer margin convex; tornus in a nearly right angle; inner margin straight. DHW ground color brown, densely covered with long and thin hair-like scales; veins a little darker; fringe bicolor, proximal half brown and distal half creamy. VHW ground color brown, presence of three small dark brown spots in spaces Rs-M 1, M 3 -CuA 1 and CuA 1 - CuA 2; veins more discernible than in VHW; fringe as in VFW.

Abdomen. Dorsally brown; ventrally covered with long, thin slighter brown hair-like scales.

Male genitalia ( Fig 13 ) (n = 2). Tegumen longer than wide, oval in dorsal view, distal margin convex. Ventral projection of the tegumen fused with dorsal projection of the saccus, narrow, with an “elbow” at the middle. Saccus slightly longer than tegumen and slightly upturned. Uncus longer than tegumen, with setae on the dorsal margin, distally slightly bifid; in lateral view narrower in the anterior and posterior regions than in the middle, where it forms an acute angle. Gnathos bifid, as long as uncus, wider in the proximal region in lateral view, becoming narrower in the distal region, with a sharp tip. Valva about 2.5 times as long as wide, proximal margin rounded; costa long and narrow and ventral margin sinuous; sacculus triangular, wider in the basal portion, but not expanded dorsally; ampulla triangular, with serrated dorsal margin, ending in a short pointed distal projection directed inwards, with presence of some small structural dots; harpe elongated, with a short dorsal projection in the middle, and outer margin serrated, ending in a short pointed distal projection. Aedeagus with approximately same length as valva, stout; distal part bilobed from the middle, the dorsal lobe distally rounded and shorter than the ventral lobe; ventral lobe truncated and with a short spine-like process close to the distal end and directly ventrad; external part longer than internal part.

Female. Unknown.

Distribution ( Fig 17 ). Enosis ester sp. nov. is known only from its type locality: [Locality of Cascatinha, cur- rently destroyed] Curitiba , Paraná, Brazil.

Etymology. The species name is dedicated to Ester Assmann, the first author’s grandmother, in gratitude for her support and encouragement in his academic life. The name is a feminine noun in apposition.
