Proxima ocellata DeLong & Freytag, 1975

( Figs 1–12 , 52, 53 )

Proxima ocellata DeLong & Freytag, 1975: 111 .

Diagnosis. Forewing ( Fig. 4 ) without dark maculae. Male pygofer ( Fig. 7 ), in lateral view, with apical portion curved dorsally. Subgenital plate ( Fig. 8 ), in ventral view, with inner margin slightly convex. Style ( Fig. 10 ), in lateral view, with ventral margin excavated at median third and serrated. Aedeagus ( Figs 11, 12 ) with atrial processes bifid apically; shaft with pair of lateral bifid subapical processes; apex bifid, forming short spatulate processes.

Measurements (mm). 8.8 (male).

Coloration. Color pattern as in generic description.

External morphology. Forewing ( Fig. 4 ) without extra-numerary veins. Other characters as in generic description.

Male terminalia. Sternite VIII ( Fig. 5 ), in ventral view, subrectangular; approximately 1.4 times wider than long; lateral margins rectilinear; posterolateral angles rounded; posterior margin with a small median lobe, slightly emarginated medially. Valve ( Fig. 6 ), in ventral view, approximately 2.5 times wider than long; posterior margin slightly excavated medially. Pygofer ( Fig. 7 ), in lateral view, with ventral margin broadly rounded; posterior margin oblique; apex subacute, curved dorsally. Subgenital plate ( Fig. 8 ), in ventral view, 3.5 times longer than wide; ligulate; outer lateral margin slightly excavated medially; inner lateral margin widely rounded; apex rounded. Connective ( Fig. 9 ), in dorsal view, with robust arms slightly longer than stalk; anterior margin slightly excavated; stalk short and expanded apically. Style ( Fig. 9 ), in dorsal view, with truncated lateral lobe; in lateral view ( Fig. 10 ), with high blade for almost entire length, abruptly narrowing apically; ventral margin serrated, excavated at median third; apex acute and curved dorsally. Aedeagus ( Figs 11, 12 ) with preatrium short; dorsal apodeme poorly developed, with dorsal margin rounded, not expanded laterally; pair of atrial processes strongly expanded medially, ventral margin with tooth at median third, apical third bifid, forming a dorsal branch with approximately twice the length of the ventral branch, both acute and direct anteriorly; shaft long, slender and subtubular, slightly flattened laterally, with pair of lateral, short and bifid subapical processes, ventral branch about twice longer and thicker than dorsal branch; apex bifid, forming short spatulate processes, poorly sclerotized.

Female unknown.

Material examined. Minas Gerais: 1 ♂, “ Brasil, Minas Gerais,\ Itabirito, Vale dos Tropeiros, Cachoeira das Carrancas,\ 10.x.2010, 20°12’28.3”S,\ 43°38’26”W, 1046m, L.\ Dumas & N. Ferreira Jr. ”, “DNA voucher\ Entomologia, DZRJ \ ENT 1313 ” “ DZRJ- AUCH \ 0228” ( DZRJ) .

Notes. Proxima ocellata can be easily distinguished from other species of the genus by its aedeagus with bifid atrial processes ( Fig. 11 ).Although in this study, the holotype was not studied, there is no doubt about the identification of the specimen redescribed here, which agrees completely with the original description and illustrations ( DeLong & Freytag, 1975).
