Cyana coccinea coccinea ( Moore, 1878)

( Figs 3, 4 , 162 , 235 )

Bizone coccinea Moore, 1878 , Proceedings of the Scientific Meetings of the Zoological Society of London 1878: 28, pl. 3, fig. 14 (Type locality: “ Sikkim ”).

= coccina, misspelling.

Type material examined. Lectotype (designated herein): ♂, handwritten label “ Sikkim ♂ ” (upper side) “ Bizone coccinea (type) Moore ” (under side) / printed label “Moore Coll. 94–106” / printed round label with a red circle “Type” / printed label with a unique identifier “NHMUK010402096” (Coll. NHMUK).

Other material examined. SIKKIM: 24 ♂, India, Sikkim , Legship, 500 m, 24–28.VII.1990, leg. W. Thomas, slide MWM 34417 (♂) Volynkin (Coll. MWM / ZSM) ; WEST BENGAL: 5 ♀, India, Darjeeling , 5 km oberh. Rambi, 800 m, 30.VII.1990, leg. W. Thomas (Coll. MWM / ZSM) ; 2 ♂, 2 ♀, India W.B., Darjeeling , Manjitar, 700 m, 20.VII.1990, leg. Dr. W. Thomas, slide MWM 34418 (♀) Volynkin (Coll. MWM / ZSM) .

Remark. In the original description, Moore (1878) did not mention a number of specimens therefore the existence of syntypes is possible. In order to stabilize the nomenclature, we designate the specimen labeled as ‘type’ as lectotype.

Diagnosis. Forewing length is 13–14.5 mm in males and 18–19 mm in females. Cyana coccinea coccinea can be distinguished from other members of the C. insularis group (sensu Lourens 2017) by its orange and red forewing in males (those are white and red in other species). Externally female of C. coccinea coccinea is similar to C. weerawoothi Lourens, 2017 ( Figs. 9, 10 ) described from Thailand, but differs by its slightly larger size and slightly narrower red parts of ante- and postmedial lines. The male genitalia of all species of the C. insularis group are very similar. Cyana coccinea differs from C. weerawoothi ( Fig. 164 ) by its longer and distally narrowed subbasal dorsal diverticulum, smaller apical diverticulum, larger cluster of spinules on the lateral diverticulum, and its smaller lateral patch of the ventral diverticulum. The female genitalia of C. coccinea differ from those of C. weerawoothi ( Fig. 237 ) by their sclerotized cervix bursae being shorter and more narrowly rugose, smaller and less dentate rugose sclerotized postero-lateral cluster of corpus bursae, and its lateral band-like signum being broader anteriorly.

Distribution. The nominate subspecies is Himalayan, known from North-East India (Sikkim and north of West Bengal) ( Hampson 1900) and Nepal ( Kishida 1995; 1998, as coccina, missp.). The records for Thailand, Vietnam and Cambodia ( Černý & Pinratana 2009; Bayarsaikhan & Bae 2016) belong to C. weerawoothi .
