( Figs. 1-6 View Figures 1-3 View Figures 4-7 )

Diagnosis. The male specimen examined has integument black. Antennae long attaining base of distal one-fourth of elytra; scape and pedicel with dorsal yellowish-brown pubescence, exposing integument at: distal fourth of antennomere III, VI, VIII, X and XI, half of antennomere IV, distal four-fifths of antennomere V, VII and IX. Antennal formula (ratio) based on length of antennomere III: scape = 1.00; pedicel = 0.21; IV = 1.05; V = 0.81; VI = 0.65; VII = 0.58; VIII = 0.52; IX = 0.44; X = 0.39; XI = 0.30. Pronotum with slender dark longitudinal bands, in the middle, from base to apex. Scutellum with slender longitudinal yellowish-brown pubescent band. Elytra with oblique longitudinal yellowish-white pubescent band, vaguely mottled with dark-brown pubescence, at basal half, from outer edge (not attaining humerus) to suture, joined to slender longitudinal yellowish-white pubescent band along suture from a bit beyond middle to almost before apical quarter; transverse yellowish-white pubescent band, from suture to outer edge, at preapical area; apical edge with yellowish-white pubescence; apex obliquely emarginate.

Bisaltes . ( B.) brevicornis is very similar to Bisaltes ( B.) confusa described from Peru. However, it differs by inferior ocular lobes of the eyes as long as genae (shorter than the genae in B. ( B.) confusa ), antennomere III exposing integument on distal one-fourth (antennomere III not exposing integument in B. ( B.) confusa ), scutellum large with slender central pubescence forming longitudinal band (scutellum small with wide central pubescence not forming longitudinal band in B. ( B.) confusa ), oblique longitudinal yellowish-white pubescent band not reaching humerus and attaining the suture beyond the middle (reaching humerus and attaining the suture almost before the middle in B. ( B.) confusa ). The other four species of Bisaltes recorded to Peru are very different, mainly in the design of the elytral pubescence.

Distribution. Currently, Bisaltes ( B.) brevicornis it is known from Brazil ( Minas Gerais), Ecuador ( Loja) and Bolivia ( Breuning 1939, 1971; Bezark 2023; Tavakilian & Chevillotte 2023; Monné 2024). Herein we report this species from the Peruvian region of Lambayeque, representing a new country record for this species. The male specimen was hand-collected in an urban area of the city on leaves of Duranta erecta L. ( Verbenaceae ).
