REMARKS

The single adult specimen is posteriorly severed. It conforms to most of the details in the original description of C. tridentina from the Italian Alps, the male efferent system included. The spermathecae also agree, except that the ectal duct is shorter than originally described, measuring c. 30 µm by 9 µm, being only 1.5 × as long as the spherical ampulla (its diameter 20 µm). In the original description, the ectal duct is 4-5 × as long as the ampulla; dimensions are not given. It is impossible to say at the moment whether this difference is intra- or interspecific. Different ectal duct lengths are known in C. atrata (Bretscher, 1903) , but that taxon may be a species complex. The clitellum is dorsally closed in our material and the prostomium has numerous internal papillae; these details are not originally described for C. tridentina . There are up to nine setae per bundle. Coelomocyte are broadly oval or rounded in C. tridentina ; they were not seen in our material. The present record, if identified correctly, would be the first after the original description.
