Diagnosis. Tomarus rosettae is externally similar to T. roigjunenti . The labium in T. roigjunenti lacks a small tooth at its center apex ( Fig. 7e ), whereas T. rosettae has a small tooth at the center apex ( Fig. 7f ). The clypeal teeth are nearly contiguous in T. roigjunenti ( Fig. 4e ), but the teeth in T. rosettae are distinctly separated ( Fig. 4f ). The parameres are also different between T. roigjunenti and T. rosettae (compare Fig. 11e , 12e , 13e and 11f , 12f , 13f ).

Life History. Adults are attracted to lights at night.
