4. Cephennomicrus indistinctus species group

Three species that belong here share an unmodified frons in males; sharply delimited dimerous and strongly flattened antennal club; and the aedeagus with paired bunches of dense, needle-like sclerites flanking simple, uncoiled flagellum and subapical region of dorsal wall bearing paired setae. This group is very similar to the C. mediorugosus group in the general body shape and the aedeagal structure, but do not have any cephalic modifications in males. Here belong C. indistinctus sp. n., C. marunensis sp. n. and C. baroalbanus sp. n.
