Cenophengus is morphologically similar to Cleicosta: both genera exhibit separated tentorial pits, vertical frons and simple tarsomeres. Additionally, in Cenophengus, the pronotum is rectangular and each elytron leaving the last 3 abdominal segments exposed, in Cleicosta pronotum, it is subquadrate in shape (slightly wider than long) and each elytron is short, leaving the last 5 abdominal segments exposed. Other important characteristics in Cenophengus are of the parameres of the aedeagus: symmetrical in dorsal view, slightly widened towards the middle, apex with spines mesad; in Cleicosta, parameres narrowing slightly after middle towards apex, apex without spines.
