Remarks. First record of O. rotundus for Goiás state. The specimens most recently collected are not dorsally glabrous as illustrated by Clarkson & Short (2012), the elytral surface has rows of fine systematic punctures bearing short setae similar to O. humboldti sp. n. but can be easily differentiated by the aedeagus (see diagnosis of O. humboldti sp. n.).
