Bicellonycha Motschulsky, 1853 ( Figure 5 A – B )

This genus can be diagnosed by clypeus connate or fused to frons, head wider than distance between hypomeres, tarsal claw with anterior and posterior halves bifid; and lanterns present on abdominal sterna VI and VII. Males usually have greater eyes and lanterns than females, but smaller mandibles; sexes are otherwise very similar. All species collected at the Serra dos Órgãos are nocturnal. Cicero (1982) described the immature

stages of Bicellonycha wickershamorum Cicero, 1982 , and Costa et al. (1988) described the immature stages of Bicellonycha lividipennis Motschulsky, 1854 .
