Description. Adult. Coloration. Brownish yellow; head and thorax with brown dots. Antenna yellow, scape and pedicel ochreous, segments 4–8 apically and segments 9–10 entirely brown. Mesoscutum with four broad ochreous longitudinal stripes. Forewing (Fig. 17I) with whitish veins and yellow membrane, in cell c+sc and r 1 rather whitish, with only a few indistinct, irregular pale brown dots; base and apex of pterostigma and apices of veins R+M+Cu, Rs, M 1+2, M 3+4, Cu 1a, Cu 1b, and A medially with relatively large dark brown spots. Pro- and mesofemora with brown subapical band, pro- and mesotibiae dark yellow, protarsus brown.
Structure. Forewing (Fig. 17I) ovoid, widest slightly distal to the middle, broadly rounded apically; wing apex situated in the middle of margin of cell r 2; C+Sc relatively evenly curved; pterostigma distinctly narrower than r 1 cell in the middle, widening to apical two thirds; Rs hardly curved in basal two thirds, distinctly curved to fore margin apically; M longer than M 1+2 and M 3+4; Cu 1a relatively evenly curved, ending proximal of M fork; surface spinules present in all cells, leaving narrow spinule-free stripes along the veins, forming hexagons of a single row of spinules, spinules absent from basal half of cell c+sc. Hindwing with ungrouped (5–6) costal setae, sometimes with distinctly grouped (3 + 2–3) costal setae. Metatibia bearing 7–10 grouped apical spurs, arranged as 4 + 3–6, anteriorly separated by 1 bristle.
Terminalia (Fig. 29G–L). Male. Proctiger weakly produced posteriorly in basal half; densely covered with very long setae in apical two thirds. Subgenital plate, in lateral view, subtriangular; dorsal margin weakly concave; posterior margin irregularly convex; with sparse long setae. Paramere, in lateral view, narrowly irregularly lanceolate, with mostly subparallel margins in basal two thirds, irregularly narrowing to apex; apex sclerotised, in lateral view, narrow, subacute, directed slightly anteriad; in dorsal view, apex narrow, acute, directed inwards and slightly anteriad, bearing a small sclerotised tooth; outer face with sparse, moderately long setae laterally in apical two thirds; inner face with dense, relatively short setae in apical half and very long setae basally; posterior margin with very long setae. Proximal segment of aedeagus with apical part moderately subdivided. Distal segment of aedeagus almost straight in basal half with dorsal margin weakly sinuate; ventral process situated slightly distal of the middle of the segment, short, in lateral view, narrow, simple, lamellar, lacking lateral lobes, in dorsal view, ventral process ovoid, broadest medially, rounded apically; apical dilation, in both lateral and dorsal views, moderately broad, slightly widening towards broadly rounded apex, dorsal part of apical dilation membranous and produced at base; sclerotised end tube moderately long and almost straight.—Female terminalia cuneate; densely covered with long setae. Dorsal margin of proctiger, in lateral view, slightly concave distal to the circumanal ring, apical part straight, apex pointed; in dorsal view, apex blunt; circumanal ring, in dorsal view, cruciform. Subgenital plate, in lateral view, strongly narrowed in apical third, apex pointed; in ventral view, apex blunt.
Fifth instar immature. Coloration. Pale yellow; cephalothoracic sclerite, antenna, wing pads, legs and caudal plate pale to bright brown.
Structure. Eye with one short simple ocular seta dorsally.Antennal segments with following numbers of pointed sectasetae: 1(0), 2(2: one large and one small), 3(0), 4(2), 5(0), 6(2), 7(1), 8(1), 9(0), 10(0). Forewing pad with five marginal pointed sectasetae; hindwing pad with two marginal pointed sectasetae; both pads lacking sectasetae dorsally. Metatibiotarsus relatively long; tarsal arolium broadly triangular apically,> 1.5 times as long as claws. Abdomen lacking lateral pointed sectasetae anterior to caudal plate. Caudal plate with anterior margin remote from anterior margin of extra pore fields; with 3–4 (1 + 2 or 3) long and narrow pointed sectasetae on either side laterally, and three long and narrow pointed sectasetae subapically on either side of circumanal ring dorsally. Extra pore fields forming continuous outer and inner bands, consisting of large oval and rounded patches; outer band long medially, end pointing outwards. Circumanal ring large.
Host plant. Miconia manauara R. Goldenb., Caddah & Michelang., M. phanerostila Pilg. (Melastomataceae).
Distribution. Brazil (AM).
Derivation of name. Dedicated to Professor Renato Goldenberg, leading systematist of Melastomataceae, for his invaluable help in identifying many specimens of this taxonomically difficult plant family.
Comments. Within the trematos -group, M. goldenbergi sp. nov. resembles M. clavata sp. nov. and M. dimorpha sp. nov. in the narrowly lanceolate paramere. It differs from the last species in light body colour and the asymmetric (versus symmetric) paramere. M. goldenbergi differs from M. clavata in the much shorter ventral process of the distal aedeagal segment, and the straight (versus upturned) apex of the female proctiger.
