Diagnosis.

1.6-2.1 mm (mean = 1.78 mm; n = 5), 2.67-3.0 × as long as wide. This species is distinguished by the elytral apex broadly rounded and entire, posterolateral margin distinctly carinate to striae 6, carina unequally serrate and appearing broken, serrations on interstriae 1 and 2 subquadrate that are at least 2 × the size of other serrations.

Distribution.

Brazil* (Bahia), Costa Rica (Cartago, Puntarenas), Ecuador* (El Cotopaxi, Orellana), Guatemala* (Zacapa), Panama ( Panamá Oeste), Peru (Madre de Dios).

Biology.

This species is only known from Senna ( Fabaceae ) and Miconia caudata and Tibouchina ( Melastomataceae ). Wood (1982) reported that the tunnels were constructed in limbs and saplings of unidentified trees 10-15 cm in diameter. In addition, we report this species from twigs as small as 7 mm in diameter and a bole 25 cm in diameter. Specimens were also collected by canopy fogging.
