subgen. nov.

Mayaesalus View in CoL Paulsen , new subgenus of Trogellus , Paulsen.

Type species: Trogellus narizotus Paulsen, here designated.

Description. This subgenus is distinguished morphologically based on the rounded clypeal apex and the snail-shaped, asymmetrical median lobe of the male genitalia. The pronotum of species in this subgenus completely lack the tubercles that are found anterior to the scaled punctures in species of the other subgenera. Species of this subgenus have blunt dorsal bristles, not acute as in the nominal subgenus. The protibiae may be either tridentate or quadridentate, and the metatibiae of males have a strong external tooth. The body form is shorter ( Fig. 17 View Figures 15–17 ) than in species of the subgenus Trogoides .
