Mesoconius oblitus group

Diagnosis

Outer vertical bristle absent, katatergite not strongly swollen. Upper frontal orbital bristle present or absent. Wing evenly infuscated brown or black, with a discal clear area or with clear spots. Male and female genitalia, where known, highly diverse, with nothing to suggest that this is a natural group.

Remarks

Like the M. nono group, the M. oblitus group is a heterogeneous assemblage of species that would have previously been treated as Zelatractodes . Most species in this group are known only from older types, and information on male genitalia is available for only three species out of 16. The group is shown as paraphyletic on the CO1 tree ( Fig. 50 ), which includes one undescribed species, as well as eight of the 16 named species in the group. The undescribed species is known only from a single damaged female specimen from southern Ecuador.
