Cyana coccinea flavotincta ( Draudt, 1914) , stat. nov.

( Figs 5–8 , 163 , 236 )

Chionaema coccinea form flavotincta Draudt, 1914 , Die Gross-Schmetterlinge der Erde 10: 174 (Type locality: [N Myanmar, Kachin State] “Bhamo”).

Type material examined. Lectotype (designated herein) ( Fig. 8 ): ♀, “Bhamo | Nov. | tea” / “ Chionaema | coccinea | ab. flavotincta | Holotype Strand Draudt | Hampson Ab. 1.” / “Moore Coll. 94–106.” / round label with a red circle “ Type ” / label with a unique identifier “NMHUK010402097” (Coll. NHMUK).

Other material examined. INDIA. ASSAM: 3 ♂, 8 ♀, NE India, Assam, Kaziranga Wild Life, Pan Bari Reserv [e] Forest , 26°45’N, 93°10’E, 100 m, 12–21.XI.1997, leg. V. Siniaev & M. Murzin, slides MWM 34419 (♂), MWM 34420 (♀) and ZSM Arct. 2019 - 528 ♀ Volynkin (Coll. MWM / ZSM) .

Remarks. 1. Draudt (1914) described Chionaema coccinea form flavotincta for the specimens mentioned by Hampson (1900) as “Ab. 1”. Despite Hampson (1900) cited two males and three females, we found only one female originating from Bhamo and labeled as “Type” in the NHMUK collection. To avoid any confusion in the future, here we designate this specimen as lectotype. 2. Like some other species of Cyana (e.g., C. puer and C. khasiana ), C. c. flavotincta is represented by two color forms: the orange (type) and the most common crimson ones. The most specimens from Assam are crimson, but one female ( Figs 7 , 236 ) has an orange patterned thorax, orange transverse lines and pale orange hindwing similar to those of the lectotype from Myanmar ( Fig. 8 ). The genitalia of these two forms have no differences.

Diagnosis. Forewing length is 13–13.5 mm in males and 16.5–17 mm in females. Male of C. c. flavotincta differs from that of the nominate subspecies by its smaller size, and paler, yellow subbasal and discal areas of forewing (those are orange in C. c. coccinea ). Female of C. c. flavotincta differs clearly from that of C. c. coccinea by its smaller size and slightly narrower transverse lines. The male genitalia of two subspecies are very similar, but in C. c. flavotincta the apical diverticulum of vesica is shorter. Female genitalia of the two subspecies have no significant differences.

Distribution. North East India (Assam: first record for India) and North Myanmar (Kachin State) ( Hampson 1900; Draudt 1914).
