Note. The species is identified by the original description ( Galsworthy 1997) and photographs kindly send us by R. Kendrick ( China, Honkong). The specimens labelled as BC ZSM Lep 48886 and BC ZSM Lep 65175 have been used for DNA barcoding. Molecular distance based on the Kimura two-parameter model for COI DNA barcodes between nearest B. scorpio  and B. hreblayi  is 7,88 % %; the distance between B. scorpio  and B. pinratanai  is 10,34 %.

Diagnosis. Adult ( Figs 27–29View FIGURES 25 – 31). Wingspan 31–37 mm. B. scorpio  represents own species-group, well distinct from other group of the genus. It differs externally by broader forewing, reduced brown patches in costal area, more clear medial area with reduced ante and postmedial lines and by yellow colouration of hindwing with wide terminal band.

Head, thorax and forewing bluish-green, deeper green than in other species; tegulae bordered with blackishbrown. Wing pattern with brown subbasal patch in costal part of wing, reduced to black streak below Cu trunk or not extended costal area, small medial and antemedial streaks in costal area; antemedial line weakly traceable; medial line not expressed of expressed by indistinct diffused blackish dusting sometimes; postmedial line thin, blackish, indistinct; in some specimens whitish suffusion in center of wing expressed; orbicular and reniform marked by white bordering line; subterminal line blackish uninterrupted, or slightly interrupted, with white inner borderline; subapical-apical and subtornal brown patches broader than in other species; subterminal line black, separated for streaks; cilia brown, pale greenish-grey opposite veins. The hindwing with dull greyish-brown terminal margin, pale yellowish-grey towards base and along anal margin, with clearly traceable discal spot and medial fascia.

Male genitalia. ( Fig. 41View FIGURES 41 – 45). In the male genitalia it differs from the congeners by more sclerotised, broader, slightly curved shape of valva, bearing strong spines on cucullus (autapomorphy, absent in other species), relatively large sacculus and small basal coremata, by shape of uncus, which is almost straight for two thirds, then curved on straight angle, deflected to apex, pointed and hooked apically and by structure of harpe, which is small, flattened, quadrangular, with short ventral extension. Aedeagus short broad lobes of carina, vesica tubular, in joining with carina armed with row of 5–6 strong short cornuti and cluster of small spines and scobinate patch in apical part.

Female genitalia (Fig. 53). In the female genitalia ovipositor extended, papillae anales elongate; apophyses anterior and posteriores ones rather long and strong compared with other species; antrum elongated, in apical part split for two sclerotised lobes; ductus bursae short, but longer than in other congeners; joining with elongated partially sclerotised cervix bursae; corpus bursae rounded, with lateral extension.

Distribution and bionomics. CHINA ( Hong Kong, *Prov. Yunnan), * VIETNAM (Provinces Vinh Phu, Thai Nguyen), * THAILAND (Provinces Khon Kaefi, Udon Thani, Nakhon Phanom, Sakhon Nakhon, Nan, Chiang Mai). The species occurs in lowland and hilly areas with elevation range 150– 900 m. Moths flies in March, April, May; June, August and September.
