Cephennodes yunnanensis, Jaloszynski. Including, 2007

Cephennodes yunnanensis View in CoL species group

Diagnosis. Male lacking sexual dimorphic characters; aedeagus of modified simonis form, in ventral view capsular region of median lobe symmetrical or weakly asymmetrical, apical projections elongate and asymmetrical, in lateral view median lobe with deep indentation distad basal foramen delimiting subtriangular projection, apex of ventral apical plate curved ventrad.

This newly established group includes two Chinese species: the previously known C. yunnanensis Jałoszyński, 2007a and one newly described species, from the same province. Both are externally unremarkable and very similar to each other, but their aedeagi are oddly shaped and unique, so that it is easy to identify males.
