Diagnosis. The only relative species of B. insolita sp. n. ( Figs 1–4 View FIGURES 1–7 ) is the Taiwanese B. connexa (Wileman, 1910) ( Figs 5–7 View FIGURES 1–7 ), which is clearly different from the new species by its slightly larger size and principally different forewing coloration and pattern.

The male genital capsule of B. insolita sp. n. ( Figs 8–10 View FIGURES 8–11 ) differs from that of B. connexa ( Fig. 11 View FIGURES 8–11 ) by its slightly less elongated uncus, slightly more elongated vinculum, distally narrower valva with slightly dentate outer margin, shorter, claw-shaped medial costal process directed ventrally (in B. connexa that is stick-shaped and directed distalventrally), reduced distal membranous lobe of valva, and narrower and more weakly setose sacculus. The aedeagus of the new species is more massive and the vesica is much broader than that of B. connexa . Vesica of B. insolita sp. n. has a short and broad ventral diverticulum with two clusters of 7–11 and 1–3 robust needle-shaped cornuti; the medial diverticulum is broad and granulated; the distal diverticulum with a series of 1–5 small cornuti of various size, whereas in B. connexa the ventral diverticulum is long, narrow with a dense bunch of spinules; the medial diverticulum is smaller, membranous with a compact bunch of short spinules; the distal diverticulum with a broad cluster of numerous short robust cornuti.

The female genitalia of B. insolita sp. n. ( Figs 12–14 View FIGURES 12–15 ) differ clearly from those of B. connexa ( Fig. 15 View FIGURES 12–15 ) by the short and broad antrum (which is narrow and strongly elongated in B. connexa ), the larger corpus bursae with a lateral sclerotized plate and two broad areas of strong and dense spinulose scobination (in B. connexa there is only a band-shaped sclerotized plate with short teeth without spinulose scobination), the weakly sclerotized signum bursae (which is heavily sclerotized and dentate in B. connexa ), and the appendix bursae directed anteriorly (whereas in B. connexa it is directed laterally).


External morphology of adult ( Figs 1–4 View FIGURES 1–7 ). Forewing length 7–8.5 mm in males (8.5 mm in the holotype) and 7.5–9 mm in females. The sexual dimorphism weakly expressed: within same population females slightly larger than males. Antennae of both sexes weakly ciliate. Head and thorax canary-yellow; tegulae and patagia with one black dot each. Abdomen ochreous yellow. Forewing canary-yellow at base. Subbasal and antemedial areas occupied by broad dark brown shade encircled with red and partly interrupted by red suffusion on veins. Medial area with broad canary-yellow trapezoidal area at costa. Discal spot dark brown. Postmedial and subterminal areas occupied by broad shade consisting of diffuse dark brown strokes encircled with red. Terminal area and cilia canary-yellow. Hindwing pale yellow with intense pale red suffusion; cilia pale red with admixture of yellow scales.

Male genitalia ( Figs 8–10 View FIGURES 8–11 ). Uncus long, narrow, laterally flattened, slightly curved, with small claw-shaped tip. Tuba analis broad; scaphium thin, weakly sclerotized; subscaphium broad, setose. Tegumen moderately long and broad. Juxta broad, trapezoidal. Vinculum large, heavily sclerotized, U-shaped. Valva elongated, lobe-shaped, with costal margin curved in its basal third. Distal part of costa broad, with large trigonal apical process, and two small denticle-like processes on its outer margin. Medial costal process short, narrowly trigonal, with hook-shaped curved tip. Distal membranous lobe of valva reduced, very short. Sacculus narrow, weakly setose; its distal process very short, trigonal. Aedeagus massive, narrow, long, almost straight. Vesica broad, membranous, curved dorsally, with three diverticula on its outer margin. Ventral diverticulum short and broad, with two clusters of 7–11 and 1–3 robust needle-shaped cornuti. Medial diverticulum broad, granulated. Distal diverticulum granulated, with a series of 1–5 small cornuti of various size. Basal plate of vesica ejaculatorius small, stick-shaped.

Female genitalia ( Figs 12–14 View FIGURES 12–15 ). Ovipositor short and broad. Papillae anales large, rectangular with rounded corners. Apophyses long and thin, of equal length. Ostium bursae broad. Antrum short and broad, trapezoidal, weakly sclerotized. membranous anterior section of ductus bursae very short. Corpus bursae elongated, sack-shaped; its posterior two-third with a lateral sclerotized plate and two broad areas of strong and dense spinulose scobination. Anterior third of corpus bursae membranous, with round and weakly sclerotized signum. Appendix bursae small, membranous, sack-shaped, situated ventro-laterally and directed anteriorly.

Distribution. Barsine insolita sp. n. is found in North East India (north of West Bengal and Sikkim), Thailand (Kanchanaburi, Tak, Chiang Mai, Nan, Nakhon Nayok, Mae Hong Son, Phetchabun, Ubon Ratchatani and Surin Provinces), Laos (Bolikhamsai and Champasak Provinces), Cambodia (Kampot Province) and Vietnam (Tuyen Quang and Bac Kan Provinces).

Etymology. In Latin, ‘insolitus’ means ‘unusual’. The specific epithet refers to the unusual external appearance of the new species, which is more similar to members of the genus Miltochrista than to Barsine .
