Remarks. 1.
This taxon was treated as a junior synonym of
Cyana subornata
(
Walker, 1854
)
distributed in
Sri Lanka
(
Hampson 1900
;
Draudt 1914
;
Strand 1922
). However, significant external and genital differences prove its species status.
2.
In the original description,
Swinhoe (1891)
did not mention a number of specimens, but cited two localities therefore the existence of
syntypes
is obvious. In order to stabilize the nomenclature, we designate the specimen deposited in NHMUK and labeled as ‘type’ as
lectotype
.
Diagnosis.
Forewing length is
13–13.5 mm
in males and
15–16 mm
in females.
Cyana linatula
is a closest relative of
C. subornata
(
Figs 28, 29
), but can be easily distinguished by its inner black edging of the antemedial line and outer black edging of the postmedial line, whereas in
C. subornata
both lines are pure red. The male genitalia of
C. linatula
differ from those of
C. subornata
(
Fig. 174
) by the larger ventral subbasal diverticulum, the larger dorsal medial diverticulum, and the presence of a cluster of small spinules on the tip of the distal diverticulum. The female genitalia of
C. linatula
differ from those of
C. subornata
(
Fig. 247
) by their broader ostium bursae, more strongly rugose posterior section of corpus bursae, and more robust spinulose scobination of the appendix bursae.
Distribution.
India
(
Rajasthan
,
Meghalaya
,
Maharashtra
,
Tamil Nadu
,
Karnataka
,
Kerala
) (
Singh
et al.
2014
, as
C. subornata
). The record for the Andaman Islands (
Swinhoe 1891
) belongs to
C. rudloffi
.
