Diagnosis.
The new species is similar to
C. ussurica
, but differs in its larger wing expanse, distinct discal spot, presence of terminal maculation on the forewing, and by the structure of male genitalia (particularly the configuration of valva and shape of vesica and cornutus).
Description.
Adult (
Figs. 1, 2
). Wingspan
31–32 mm
. Body and wings pure white with bluish-silver shining. The 3rd segment of palpi with some black scales at base. Tibia and 1–2 segment of foretarsi with black scales at base. Forewing with distinct discal dot represented by group of 4–5 black scales on discal vein in lower angle of R-Cu cell (which are weakly expressed in
C. ussurica
). Terminal line represented by distinct small black transversal streaks (lacking in
C. ussurica
). Cilia white. Underside white.
Male genitalia
(
Fig. 4
). Similar to
C. ussurica
, but differing in shape of juxta, thinner, somewhat shorter and more curved end of valva and shape of cornutus. All structures strongly sclerotized. Uncus moderate, relatively short, straight; tegumen curved, with wide branches; juxta wide, rhomboid (in
C. ussurica
it is shield-shaped). Valva wide at base, with well expressed transtilla; sacculus large (substantially smaller in
C. ussurica
); clasper with small sclerotized patch, harpe absent (reduced to tiny extension in
C. ussurica
); distally from sacculus valva narrower and in terminal fourth represented only by costa, which is strongly curved ventrally and pointed (in
C. ussurica
somewhat longer and curved to a lesser degree). Aedeagus narrower than in
C. ussurica
; vesica short, bulbous, larger than in
C. ussurica
; cornutus beak-shaped, somewhat smaller than in
C. ussurica
,
not spatulate and apically extended. Female unknown.

Distribution and Biology.
(
Fig. 12
). The species is known only from the
type
locality, Prov.
Shaanxi
in Central
China
. Adults were collected in early July.
Etymology.
The species is dedicated to my colleague and friend, Gottfried Behounek, who presented the material from his collection for description.
