( Figs. 11, 12, 25, 39, 42, 45, and 48)

Diagnosis. This species resembles B. magnifica . It can be differentiated from other Bergiantina species by the following characters: a) inner margin of forewing antemedial line with a very thin white strip difuminated toward the base; b) inner margin of postmedial line with a wide white patch between R2 and CuA1 veins; c) male genitalia apical half of right valve with two ventral conical knobs on medial notch; d) apical half of right valve with two triangular setae protuberances, the dorsal-posterior one bigger than the central one.

Description. Male ( Figs. 11 and 12). Head: Front and palpus dark brown, sprinkled with white scales. Antenna dark brown, bipectinate (mayor segment five times wider than central shaft). Thorax: Reddish brown densely sprinkled with white scales; tegula as ground color, posteriorlly bordered by a blackish blurred line sprinkled with white scales; without white spot at base of forewings; meso and metathorax laterally orange yellow. Legs dark brown, with tufts of hairs on tibiae, this are proximally yellowish white and distally black. Forewing length 21.5, ground color greyish red, densely covered with white scales; costal region darker; basal line absent; antemedial line red, extending from costa to posterior margin, waved, attenuated in discal cell, inner margin with a very thin white strip in all its length; orbicular and reniform spots black, faint; postmedial line red, 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, extended to subterminal line by interspaces CuA2-CuA1 and M1-R5, inner margin with a wide white patch between R2 and CuA1; terminal area with white tint; terminal area with silvery or white tint extending from terminal line to beyond subterminal line, as a blurred strip; subterminal line red, strongly crenulate; terminal line thin and black; fringe black with white spots at the ends of the veins. Underside ground color dark brown, basal shade orange yellow united with the concolorous postmedial shade along inner margin; spot in anterior end of postmedial shade reduced to some white scattered scales; terminal area with yellowish spots at ends of the veins; terminal line black; fringe with the same pattern that in the superior face. Hindwing ground color orange yellow; marginal band blackish brown heavily sprinkled with yellowish scales, widest near apex, with irregular inner margin, oblique from costa to M3 vein and extending along costa to base; discal spot very faint; fringe black whit some scattered white scales at veins end. Underside marginal band blackish brown heavily sprinkled with yellowish scales; discal spot connected to marginal band. Abdomen: Blackish brown, orange yellow at posterior end and with two concolorous spots in lateral margins of first three or four segments; ventrally without scattered white scales. Genitalia: Uncus 1/4 as long as valve, curved, basal third without lateral lobes, apex rounded. Tegumen with posterior-lateral lobes little protrude and slightly curved ventrally. Juxta less than 1/2 length of valves, 3X 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 of different form: right valve with two triangular setae protuberances, the dorso-posterior one bigger than the central one and with two ventral conical knobs on medial notch, and left valve with a dorsal larger knob; valve apex of right valve with two ventral knobs at medial notch ( Fig. 25). Apical end of aedoeagus with a sclerotized horn-like dorsal projection, 2/5 as long as aedoeagus ( Figs. 39 and 42); left plate of aedoeagus longer than the right one, reaching the end, and with a single small lateral tooth, triangular and bifid ended, and a greater terminal tooth ( Fig. 45). Female. Unknown.

Etymology. This species is named in honor of our families, for their affection and constant support.
