The species is dedicated to Jan-Peter Rudloff, collector of the type series. Diagnosis . Forewing length is 12.5–13.5 mm in males and 14.5–15 mm in females. Cyana rudloffi is a closest relative of the continental C. obliquilineata . The male of the new species differs externally from that of C. obliquilineata by the red subcostal patch in the postmedial area only (that is blackish in C. obliquilineata ). The female of C. rudloffi differs by its broader ante- and postmedial and subterminal lines. In the male genitalia, C. rudloffi differs from C. obliquilineata by its slightly broader valva with costa being strongly angled medially, more robust distal saccular process being more broadened distally, thinner spinules of the lateral clusters in the vesica, and the shorter and broader distal diverticulum of vesica bearing slightly more robust spinules apically. The female genitalia of C. rudloffi differ clearly from those of C. obliquilineata by the longer and continuous band of more robust spinules in the posterior section of corpus bursae (in C. obliquilineata that is shorter and interrupted into two bands).
