Diagnosis.

This unique species of Reinmara can be recognized by the black suffusion along the entire length of the forewing postmedial line in males, which reaches the apex, darkening it. In both males and females there is a well-defined, narrow, pale pink suffusion along the postmedial line (outside of the black suffusion of the males, which is absent in females), leaving the remainder of the medial area mostly clear of pale pink suffusions. The male genitalia is recognizable by the uniformly narrow phallus with a usually distinctly backward splayed distal ventral tip, the uncus is quite broad. Among the species for which the female is known, R. minasa female genitalia is characterized by the largest dorsal projection of the tergite VIII as well as by the robustness of the lateral plates below the papillae anales.

Description.

Male.Head: As for genus, coloration light brown. Thorax: Coloration as for head but with pale pink scales present on prothoracic collar and base of wings. Legs: Coloration as for thorax, but with additional, dark petiolate scales sparsely scattered amongst vestiture, tarsus yellower. Forewing dorsum: Forewing length: 16.5-21.0 mm, avg.: 18.1 mm, wingspan: 33.0-42.5 mm, n=9. Acutely triangular, narrow, outer margin concave; tornus deeply notched nearly until postmedial line, apex somewhat falcate. Ground color brown, very sparsely scattered with dark brown, tiny petiolate scales. Antemedial area with pale pink hue, medial area displaying narrow strip of ground color between pink hue of antemedial area and inner pink suffusion of postmedial line, submarginal area darker brown than medial area with pale gray lunule-like marking on margin and strong, black suffusion on outer edge of postmedial line, black suffusion becoming widest and more diffuse near tornus, extending along entire postmedial line to apex. Antemedial line hardly distinguishable but present as outwardly bent brown wave, postmedial line nearly straight. Discal mark variable from pale pink splotch with little to no black scales in center to almost entirely covered by black scales. Fringe coloration nearly white with darker scales at wing vein intersections. Forewing ventrum: As for genus but pale pink scales along postmedial line broadly scattered, postmedial line as on dorsum straight, but only fainter, black suffusion replaces lunule-like submarginal shape of dorsum. Hindwing dorsum: Notch on anterior margin weak, patterning as for forewing dorsum, but antemedial line absent, discal mark nearly always absent, pale suffusion submarginally similar to forewing lunule-like area. Hindwing ventrum: Following same pattern as forewing ventrum but postmedial line wavier, discal mark present, pale pink suffusion widely expanded throughout medial and submarginal areas. Abdomen: As for genus. Genitalia: (Fig. 29) n=4. Typical of genus, differing in the relative shortness and (usual) broadness of uncus, generally more robust gnathos mesal extensions with particularly elongated fingerlike tips, phallus narrow and smoothly curved, somewhat boomerang shaped, tip of phallus splayed open with ventral edge forming backwardly angled lip. Vesica bulbous with distally extended narrower portion. Female.Head: As for male, but antenna dentate with very small pectinations along entire length of flagellum. Thorax: As for male. Legs: As for male. Forewing dorsum: Forewing length: 21 mm, wingspan: 43 mm, n=1. As for male but much broader, margin nearly straight. Coloration and patterning as for male except outer black suffusion along postmedial line absent. Forewing ventrum: Similar to dorsum but lighter, homogenous brown without distinctly different areas of wing except for darker brown region submarginally. Antemedial line absent, postmedial line very faint, discal mark more prominent, darker than on forewing dorsum. Hindwing dorsum: Similar to forewing dorsum, notch present on anterior margin, patterning as for forewing dorsum, but antemedial line and discal mark absent. Hindwing ventrum: Following same pattern as forewing ventrum. Abdomen: Similar to that of males but more robust overall. Genitalia: (Fig. 33) n=1. Very stout, robust; tergite of VIII forms elongated, posteriorly directed tongue-like overhang, VIII heavily sclerotized laterally forming curving plate encircling the papillae anales, curved plate weakly curling backward near papillae anales. Apophyses anteriores roughly half-length of apophyses posteriores. Lamella ante- and postvaginalis converge as a wide, bowl-like structure covered in setae. Ductus bursae short, narrow. Corpus bursae rather small in comparison to robust, heavily sclerotized remainder of genitalia, baglike. Papillae anales broad, rounded, covered in long, fine setae.

Distribution

(Fig. 36). Reinmara minasa is endemic to southeastern to south Brazil, and is found in mountainous regions of the states of Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná, and Santa Catarina, at elevations ranging from 700-2000 m.

Remarks.

Until now, very little has been reported on this species. We figure and describe the female of R. minasa for the first time.
