Cephennomicrus typicus species group

A new species group is established for six species that share a modified frons in males (indistinct only in one species), with a median setose frontal impression or flattening, and a similar form of the aedeagus, which has an oval median lobe with approximately triangular apical region and the endophallus with a distinct flagellum with a broad proximal portion. Additional key characters are: the antennae with an indistinctly delimited, slender, trimerous club; the body covered with very short and recumbent, barely noticeable setae; the pronotal base with five pits, three of them connected by a transverse groove. This group includes species described by Scott (1922): C. cordithorax, C. cornutus, C. minor, C. perexiguus, C. politus, and C. typicus .
