( Figs. 3, 4, 19, 28, 33, 36, and 47)

Diagnosis. Bergiantina intermedia can be differentiated from other Bergiantina species by the following characters: a) outer margin of forewing postmedial line with a continuous white strip only interrupted between CuA1-CuA2; b) inner margin of forewing postmedial line with a white patch between R2 and CuA1, thickly covered by greyish red scales; c) apex of left valve with a single quadrangular projection directed distally and apex of right valve with two knobs, dorsal more protrude than basal one; and d) left plate of aedoeagus short, not reaching the end and without tooth.

Description. Male ( Figs. 3 and 4). Head: Front and palpus dark brown, sprinkled with white scales. Antenna dark brown, bipectinate (mayor segment 5 X as wide as central shaft). Thorax: Greyish white; patagium and tegula reddish brown sprinkled with white scales, both bordered by a blackish line sprinkled with white scales; white spot at base of forewings. Legs dark brown, with tufts of white hairs (more evident in fore- and middle femora and tibia). Forewing length 21.8, ground color dark greyish red, heavily covered with white scales; costal region dark; basal line absent; antemedial line red, faint, extending from costal to posterior margin, attenuated in discal cell, waved on anterior 2/3 then straight, two small white spots proximal to antemedial line, one before and one after discal cell; orbicular spot small, black; reniform black, both spots bordered of white; discal cell white inside; postmedial line faint, as a thin red line, straight from costa to R2, convex from R2 to CuA1, notched on M1 and interpace M3-CuA1, deeply concave on posterior third, outer margin with a continuous white strip only interrupted between CuA1-CuA2, inner margin with a white patch between R2 and CuA1, extended to the reniform spot, thickly covered by greyish red scales; terminal area with silvery or white tint extending from terminal line to subterminal line; subterminal line red, strongly crenulate; terminal line thin and black; fringe black with white spots at the ends of the veins. Underside ground color orange yellow; median shade wide, blackish brown sprinkled with white scales; marginal band narrowing to the inner margin; fringe black with yellowish spots at end of veins. Hindwing ground color orange yellow; marginal band dark brown, widest near apex and gradually narrows to anal angle, inner margin uniform without irregularities and not extending along costa; discal spot black, faint; fringe black with white spots at end of veins. Underside ground color orange yellow; marginal band dark brown, not extending along costa, heavily sprinkled with white scales; discal spot dark brown. Abdomen: Blackish brown, posterior end and two spots in lateral margins of first three or four segments orange yellow; ventrally without scattered white scales. Genitalia: Uncus 1/3 as long as valve, curved, basal third without small lateral lobes, ended as a tiny hook. Tegumen with posterior lobes slightly curved ventrally. Juxta less than 1/2 length of valves, 2X as long as wide, distal half with one weakly sclerotized oval depression on each side, length more or less half of juxta. Apical half of valves with an elongated carina oblique to costa, from 1/9 of valve length; apex of valve of different form: left valve with a large and quadrangular projection directed distally and right valve with two knobs, dorsal more protrude than basal one ( Fig. 19). Sclerotized horn-like dorsal projection of aedoeagus 1/3 as long as aedoeagus, basal 1/3 strongly convex and distal 2/3 concave, rugous on the posterior side, without denticles ( Figs. 28 and 33); sclerotized lateral plates: left plate short, as long as right one, not reaching the posterior end, and without any tooth ( Fig. 36). Female. Unknown.
