Abstract
TheNeotropicalgenusOgmocoris Mayr, 1864isrevised based onmorphologicalcharacters,particularly thegenitaliaofboth
sexes.Formerly monobasicwith O. hypomelas (Burmeister, 1835), onenew species is here described, O.paranaensis n. sp.
Illustrations oftheexternal genitaliaofboth sexesareprovided.
Keywords: Heteroptera, Pentatomidae,Neotropical region,Ogmocoris, newspecies
