Antennal segments 3–8 with dark brown apices, segments 9–10 entirely dark brown. Forewing ( Fig. 17F ) amber-coloured with sparse brown dots; base and apex of pterostigma and apices of veins Rs, M 1+2 , M 3+4 , Cu 1a and Cu 1b dark brown. Femora with brown dots; tarsi brown. Abdominal tergites partly and sternites entirely dark brown. Structure. Forewing ( Fig. 17F ) oval, broadest distal of the middle, broadly and evenly rounded apically; wing apex situated in cell r 2 near apex of M 1+2 ; C+Sc eakly curved in distal third; pterostigma slightly narrower than r 1 cell in the middle, weakly widening to apical two thirds; Rs almost straight in basal two thirds, obliquely curved to fore margin apically; M longer than M 1+2 and M 3+4 ; Cu 1a weakly irregularly curved, ending at level of M fork; surface spinules present in all cells, leaving narrow spinule-free stripes along the veins, forming hexagons of a double row of spinules, spinules absent from basal half of cell c+sc. Hindwing with 3–4 + 4 grouped costal setae. Metatibia bearing 8–10 grouped apical spurs, arranged as 3–4 + 4–6, anteriorly separated by 3 bristles. Terminalia ( Fig. 28M–R ). Male. Proctiger tubular, in basal third weakly produced posteriorly; densely covered with long setae in apical two thirds. Subgenital plate, in lateral view, subglobular; dorsal margin strongly, irregularly curved, posterior margin curved; with moderately long setae. Paramere, in lateral view, asymmetrically lanceolate; apex, in lateral view, blunt, directed upwards; in dorsal view, apex blunt, directed upwards, slightly inwards and hardly posteriad, lacking distinct sclerotised tooth; outer face with sparse, moderately long setae mostly in apical half; inner face with dense, moderately long setae; posterior margin with long setae. Proximal segment of aedeagus with apical part strongly subdivided, bulbous. Distal segment of aedeagus with dorsal margin weakly curved in basal half; ventral process situated in apical third of segment, in both lateral and dorsal views, very short, simple, rounded, button-like, lacking lateral lobes; apical dilation, in lateral view, relatively large, subrectangular, base bearing a large membranous lobe at dorsal margin; in dorsal view, apical dilation elongate, with slightly truncate apex; sclerotised end tube short and weakly curved.—Female terminalia cuneate; densely covered with setae. Dorsal margin of proctiger, in lateral view, slightly convex distal to circumanal ring and distinctly concave in apical half, apex pointed, upturned; in dorsal view, apex blunt; circumanal ring, in dorsal view, distinctly cruciform. Subgenital plate, in lateral view, abruptly narrowing in apical half, pointed apically; in ventral view, apex blunt. Fifth instar immature. Unknown. Host plant. Adults were collected on Miconia formosa Cogn. ( Melastomataceae ), which is possibly a host. Distribution. Brazil ( PR ). Derivation of name. Named after Miconia cabucu , noun in apposition, one of the synonyms of the probable host M. formosa . Comments. Melanastera cabucu sp. nov. resembles M. dimorpha sp. nov. in the knob-shaped ventral process of the distal aedeagal segment. The two species differ as outlined under M. dimorpha .
