Cyana harterti ( Elwes, 1890)

( Figs 68, 69 , 191 , 260 )

Bizone harterti Elwes, 1890 , Proceedings of the general meetings for scientific business of the Zoological Society of London 1890: 398 (Type locality: “Upper Assam ”).

Type material examined. Lectotype (designated herein) ( Fig. 69 ): ♀, printed label “ Ob. Ass. Hart. ” / handwritten label B. Harterti Elwes type” / pink handwritten label “214.” / printed label “ Collectio H. J. Elwes ” / printed label “Rothschild Bequest B.M. 1939–1.” / printed round label with a red circle “Type” / printed label with a unique identifier “NHMUK010402107” (Coll. NHMUK).

Other material examined. MEGHALAYA: 7 ♂, 3 ♀, NE India, W Meghalaya, Umran , 33 km N Shillong, 26°06’N, 92°23’E, 800 m, 14–23.VII.1997, leg. Sinjaev & Afonin, slides MWM 34413 (♂), MWM 34413 (♀) Volynkin (Coll. MWM / ZSM) ; ASSAM: 2 ♂, Assam , Jatinga, 12.V.2005, leg. Navneet Singh (Coll. NZCZSI) ; 2 ♂, Assam , Jatinga, 10.IX.2005, leg. Navneet Singh (Coll. NZCZSI) .

Remark. In the original description, Elwes (1890) mentioned two specimens, female and a probable male. We did not find the male syntype in the NHMUK collection. To avoid any confusion in the future, here we designate the female specimen deposited in NHMUK and labeled as ‘type’ as lectotype.

Diagnosis. Forewing length is 8.5–9 mm in males and 11–11.5 mm in females. Cyana harterti is a sister species of C. flavalba (Rothschild, 1912) ( Figs 70, 71 ) distributed in Malay Peninsula, S and SE Thailand and Cambodia ( Černý & Pinratana 2009; Bayarsaikhan & Bae 2016). These species have no external differences and can be iden- tified by the genitalia structures only. In the male genitalia, C. harterti differs from C. flavalba ( Fig. 192 ) by its smaller cornuti of the subbasal lateral and ventral clusters, and slightly larger cornuti of the distal cluster. Compared to those of C. flavalba ( Fig. 261 ), the female genitalia of C. harterti have the longer posterior sclerotized section of corpus bursae, and the slightly longer and broader appendix bursae.

Distribution. North East India (Assam, Meghalaya and Mizoram) ( Singh et al. 2014), South and South East China ( Hampson 1900), North Thailand ( Černý & Pinratana 2009, as C. flavalba (part)) and Japan (Ryukyu, Okinawa and Iriomote islands) ( Inoue 1965).
