The new species Parachorius semsanganus sp. n. is described from Laos. This enigmatic Oriental deltochiline represents a “morphological link” between Parachorius and Cassolus by sharing characters of the two genera. The fact that P. semsanganus cannot be unequivocally placed in either of these two genera stresses some more general problems of the current classification of Parachorius and Cassolus. Such problems can be solved only in the course of phylogenetic analysis, the need of which is briefly outlined.
