ABSTRACT. The morphology of the male and female genitalia of Dipchasphecia rhodocnemis O. Gorbunov, 1991, from the Republic of Sakha (Yakutia) are described and illustrated for the first time. It is established that the larvae of this species live in the roots of Goniolimon speciosum (L.) Boiss. (Plumbaginaceae: Limonieae). The biological features of the larvae are discussed and illustrated. Morphologically and in biological features, D. rhodocnemis is closest to D. altaica O. Gorbunov, 1991, but these two species differ from each other in the details of the colouration of various parts of the body, the structure of the transparent areas of the forewing, and the conformation of the genitalia of both the male and female.
