Etymology
. 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).
