Labrum with abundant pale yellow pubescence close to anteclypeus, shorter and sparser centrally, and a few long, erect brownish setae interspersed, glabrous on remaining surface, except dense fringe of pale yellow setae on anterior margin. Gulamentum glabrous, except narrow anterior area with both brownish and yellowish-white pubescence not obscuring integument. Distance between upper eye lobes 0.20 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.54 times distance between outer margins of eyes. Antennae 1.7 times elytral length, reaching elytral apex at apex of antennomere VII.

Etymology. – Colobothea vaamondei sp. nov. is named in honor of Carlos L. Vaamonde, a good friend of the first author and collector of the holotype.

Remarks. – Colobothea vaamondei sp. nov. is slightly similar to C. colombiana Monné, 1993 ( Figs 16–17), due to the pale yellow pubescent macula below the scutellum and the subcircular pale yellow pubescent bands on posterior half of the elytra. However, they differ as follows: body slender (stouter in C. colombiana ), pubescence on center of the pronotum sparser and forming a complex pattern (denser and forming longitudinal bands in C. colombiana ), sparser elytral pubescence (denser in C. colombiana ), slender and longer scape and antennomere III (stouter and shorter in C. colombiana ), posterior half of the elytra with three subcircular pubescent maculae on its superior region (two in C. colombiana ). Although the holotype of C. vaamondei sp. nov. is a female and the holotype of C. colombiana is a male, those differences cannot be considered as sexual dimorphism because this type of difference does not occur in other species of the genus. It is also similar to C. picturata Monné, 1993 by the same features of C. colombiana , and differs by the same features, except the shape and length of the scape and antennomere III. In the holotype of C. picturata the third pale yellow pubescent macula just after the middle of the elytra is present, although slightly distinct and more irregular, and the elytra are mostly covered with dense and greenish-brown pubescence.
