Description. Alar expanse 35 mm, forewing 15 mm, antenna 15 mm and body length 21 mm.

Head: labial palpus auburn, tip of second, as well as dorsal side of third palpomere dark brown; frons dark brown with purple gloss, laterally white; vertex blackish-brown, occipitally mixed with auburn; pericephalic scales black, laterally white, ventrally auburn; antenna black with intensive blue gloss, subapically white, ciliate part ochre-brown, scapus with some auburn scales basally.

Thorax: dark brown, laterally and ventrally anthracite grey with steel-blue gloss; patagia auburn, dorsocranially somewhat yellow; dorso-lateral scale tufts indistinct, black. Legs: glossy anthracite grey; foreleg with tibia interiorly orange-yellow, exteriorly with narrow, white, longitudinal stripe, tarsus ventrally white; tibia of mid- and hindleg ventrally densely mottled with white; terminal tarsomeres of hindleg white. Wings: almost hyaline, veins, margins, discal spots, fringes and costal area as well as base of forewing black; discal spot of forewing very large, triangular, basad pointing, that of hind wing very small.

Abdomen: black, segments 1–3 dorsally brown, ventrally white; anal tuft black, medio-dorsally white. The female is unknown.

Male genitalia. Tegumen distally narrowed, crista gnathi medialis present, crista gnathi lateralis short; valva ovoid, crista sacculi distally strongly curved ventrad, disto-ventrally at half way bifurcate, with a small patch of flat-topped setae at angulation; saccus short and broad, basally straight; phallus straight, basally slightly thicker, vesica simple.

Variation. The type series varies insignificantly in size, with alar expanses 35–37 mm, and in the length of the forewing discal spot.

Diagnosis. Lolibaia triangularis  is very similar and likely closely related to L. salimi  . The most obvious differences concern the colouration, which is predominantly black in L. triangularis  and mainly red-brown in L. salimi  ; the white, subapical stripe of the antenna and the narrow discal spot of the hindwing, which are present in L. triangularis  ; and the anal tuft, which is black, medially white in L. triangularis  but monochrome orange-brown in L. salimi  . The male genitalia are also very similar in both species. In L. triangularis  , the crista sacculi of the valva is straighter, the furcated, disto-ventral part is less prominent, and the ventral margin and area distal to crista sacculi is without setae (with numerous bifurcate setae in L. salimi  ).

Etymology. The species is named after the shape of the forewing discal spot.
