Femora pale in proximal half, distal half of femora, tibiae and tarsi uniformly dark brown. Cerci brown.  Male.Forewing length 9.5 mm.

In this species the dorsal aedeagal lobe is significantly larger than in  C. unidentata( Fig. 2) and the median process of tergum 9 is much longer in this species ( Fig. 1) than for either of its related congeners ( Sivec & Zwick 1989). 3112030313 1995-05-17 1995-05-31 1995-05-17 PMSL A.
