description: Bergiantina parva, new species   
(Figs. 5, 6, 20, 29, 34, 37, and 47)  
 Diagnosis. This species can be differentiated from other Bergiantina species by the following characters: a) small size, forewing length 15.6–16.7 mm; b) orbicular spot absent in some specimens and in other represented as a swelling of the antemedial line; c) apex of left valve without projection and apex of right valve with only one small knob; and d) left plate of aedoeagus short not reaching the end and without tooth.   
 Description. Male (Figs. 5 and 6). Head: Front and palpus dark brown, sprinkled with white scales. Antenna dark brown, moderately bipectinate (mayor segment three times wider than central shaft). Thorax: Reddish brown sprinkled with white scales; patagium and tegula reddish brown sprinkled with white scales, both bordered by a blackish blurred line sprinkled with white scales; white spot at base of forewings; metathorax laterally orange yellow. Legs dark brown, with tufts of white hairs on tibiae. Forewing length 15.6–16.7 mm, ground color reddish grey, densely covered with white scales; costal region obscure; basal line absent; antemedial line red, extending from costa to posterior margin, waved, notched above and below discal cell, inner margin with a white strip wider than the line in all its length; orbicular spot absent in some specimens and in other as a swelling of the antemedial line; reniform spot black; 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, inner margin with a wide white patch between R2 and CuA1, extending through discal cell to the antemedial line; 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 semitransparent, ground color dark brown, basal shade whitish extending through the postmedial; terminal area with white spots at ends of the veins; terminal line black; fringe with the same pattern that in the superior face. Hindwing ground color white or yellowish white; with a short dark brown postmedial line, strong from costa to Sc+R5, in some specimens it reaches M3 as a very thin shadow; dark discal spot sometimes present; terminal line dark brown; fringe as ground color. Underside yellowish white at the base, fading towards the apex; terminal line dark brown extending through the costa to the postmedial line. 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 of white scales. Genitalia: Uncus 1/3 as long as valve, curved, basal third without lateral lobes, ended as a terminal spine. Tegumen with posterior-lateral lobes hook-like, apex directed to the center of the genitalia. Juxta 1/3 length of valves, 4X as long as wide; distal half with one weakly sclerotized oval depression on each side, length 1/3 as long as juxta. Apical half of valves with a small rectangular carina close to costa, as long as 1/7 of valve length; apex of valve of different form: apex of left valve round, without projection and apex of right valve with only one small knob (Fig. 20). Apical end of aedoeagus with a sclerotized horn-like dorsal projection, more or less 1/3 as long as aedoeagus, smooth, without denticles or roughness (Figs. 29 and 34); left plate of aedoeagus short, not reaching the end, without teeth; right plate the same size as previous (Fig. 37). Female. Unknown.   
 Type material. HOLOTYPE: ♂ Bolivia, Cochabamba, El Limbo, 2000 (-) (IMLA). PARATYPES: 1 ♂ Bolivia, Cochabamba, El Limbo, 2000 (-) (IMLA); 4 ♂♂ Bolivia, Cochabamba, Incachaca (J. Steinbach) (USNM).   
 Etymology. From the Latin parva (small).   
 Distribution (Fig. 47). Only known from the department of Cochabamba, Bolivia.   
 Discussion. This species resembles Bergiantina dolens, being differentiated by its small size and absence of orbicular spot.
