relationships. This species is closely related to C. violaceipen- 
nis and C. aricae. The very slender, microtuberculate ovipositor tip 
and uniflated fore tibia constitute the best diagnostic features of C. 
leptaechma. Also distinctive are its low and almost symmetrically 
convex clypeal profile and strongly shining 2nd gastric tergite with 
only faint micro-reticulation and widely scattered setae.

Chile. More recent fieldwork has added 6 females and 16 males, 
permitting some additions and modifications with regard to the 
original diagnosis.
