Protosticta satoi Asahina, 1997


Protosticta satoi Asahina, 1997  —light form

( Figure 6View FIGURE 6 A–E)

Specimens examined. 3 males, Nam Bung, Van Chan district, Yen Bai Province, 14.V. 2015 and 1 male, same location, 26.IV. 2015; 1 male, Xuan Son National Park, Phu Tho Province, 18.IV. 2015; 1 male, Ba Be National Park, Bac Kan Province, 26.VII. 2013, Tom Kompier leg.; 4 males, 2 females, Xuan Son National Park, Phu Tho Province, 18.IX. 2015, Quoc Toan Phan leg.

Notes. The female specimens match the original description well (Asahina 1997) by their thoracic pattern and the presence of a large pale yellowish spot on the dorsum of S 9 ( Figs. 6View FIGURE 6 C–E). Unlike the dark form, the males and females of light form P. satoi  appear to be even less consistent in prothoracic markings. While some males have all lobes of the pronotum darkened ( Fig. 6View FIGURE 6 B), in others the pattern is more like the female illustrated here, in which only the anterior and posterior lobes are black, but the remainder is uniform pale yellow ( Fig. 6View FIGURE 6 D).

Measurements. Male. Hindwing 20–24; abdomen including appendages 39–45. Female. Hindwing 17–18, abdomen including appendages 28–29.

Distribution. Vietnam (Ba Be National Park, Bac Kan Province; Tam Dao National Park, Vinh Phuc Province; Xuan Son National Park, Phu Tho Province; Ba Vi National Park, Ha Noi; Cuc Phuong National Park, Ninh Binh Province; Pia Oac Nature Reserve, Cao Bang Province).
