Megachoriolaus Linsley, 1970  

Megachoriolaus Linsley, 1970: 128   ; Monné, 2006: 127 (cat.).

Type species: Megachoriolaus chemsaki Linsley, 1970   (original designation).

According to Chemsak (2005), this genus has a moderately robust form; the elytra parallel–sided or slightly expanded posteriorly; antennae relatively short in both sexes, basal antennomeres shiny, usually abbreviated, clothed with coarse suberect hairs, antennomere 4 short, outer antennomeres thickened or subserrate. Pronotum with punctation not finer than that of base of elytra; prosternum with intercoxal process very narrow; mesosternum with intercoxal process prominent, not recessed between coxae. Legs with procoxae prominent; posterior tarsi distinctly shorter than tibiae, first segment usually not longer than remaining segments combined. Elytra with fine, non-elevated costal lines. Abdomen with last segment in male not excavated.

Megachoriolaus   includes eight species from Mexico and Central America   : M. chemsaki Linsley, 1970   , M. flammatus (Linsley, 1961)   , M. imitatrix Linsley, 1970   , M. lineaticollis Chemsak & Linsley, 1974   , M. nigricollis Chemsak & Linsley, 1974   , M. patricia (Bates, 1885)   , M. spiniferus (Linsley, 1961)   , M. unicolor (Bates, 1892)   and M. yucatanus Giesbert & Wappes, 2000   , as well as M. cruentus (Martin, 1930)   , M. ignitus (Schaeffer, 1908)   and M. texanus (Knull, 1941)   from the mountains of the southwestern United States. We propose to add three species from South America   , previously in Euryptera   , by the presence of Megachoriolaus   generic characters as elytra parallel–sided, without dorsal carinae. These are: M. atripennis ( Bates, 1870)   , new combination, M. bicolor ( Gounelle, 1911)   , new combination and M. venustus ( Breme, 1844)   , new combination. A new species is described from Brazil (Rondônia) and Bolivia.
