Epicaerus (Diorynotus) jugicola (Sharp 1891)

Hab.GUATEMALA, Volcan de Agua 8500 to 10,500 feet (Champion).

Niger, opacus, nudus; prothorace densissime punctato-ruguloso, dorso late depresso, utrinque longitudinaliter impresso; elytris peropacis, coriaceis, seriatim fortiter punctatis.
 
Long. 13½ millim.

I separate from E. opacus two specimens of the male sex that have the sculpture of the upper surface coarser, and the rostrum rather longer and more distinctly impressed along the middle. The peculiar fine rugulose sculpture of the elytra is very remarkable in this species, and the serial punctures are considerably larger than they are in E. opacus. The shoulders of the elytra are remarkably prolonged.
