Description

Antennae upperside dark brown, underside pale brown, and yellowish brown before club. Palpi with the second segment long and erect, densely covered with yellow brown scales ventrally; the third segment thin and pointed, prominently protruding. Wings upperside dark brown, forewing cell spots conjoined, lower one larger, rectangular, spot in space CuA1 largest, spots in spaces M3, R3-R5 small, spot in space CuA2 pale yellow; hindwing without spots. Forewing underside brown covered densely with yellow brown scales at costa and apex, broadly white along dorsum distally; markings similar to those on upperside; hindwing underside ochreous with white spots in spaces CuA2, CuA1, M3, M2-M1 and Sc+R1, of which the spot in space M2-M1 largest, those in spaces CuA1 and Sc+R1 large and sub-equal, dot in space M3, all these white spots surrounded by black ferruginous spots.

Male genitalia ( Figs. 59−63 ): Uncus longer than tegumen, thin and long distally; socius slender and pointed at tip; saccus long; valva with ventrodistal process rather pointed; aedeagus with suprazonal sheath prominently shorter than subzonal sheath; juxta spade-like, thin and long basally.

Distribution.

China (Hainan), Laos ( Osada et al., 1999), Vietnam ( Ikeda et al., 2001; Miyazaki et al., 2007).

Etymology

The scientific name, parawoolletti (noun) is derived from para [= close to] + woolletti .

Remarks

The new species is very similar to S. woolletti ( Riley, 1923) from Borneo ( Fig. 21−22 , 64−69 ), but can be distinguished from it by the following characters: hindwing underside ground color ochreous; all white spots surrounded by large black ferruginous spots; the spot in space M2-M1 the largest, spots in spaces CuA1 and Sc+R1 subequal; valva of male genitalia with harpal process much broader at base and sharply pointed at the end. The new species might be considered as a subspecies of S. wooletti , but judging from the disjunct distribution as well as the morphological difference, we consider it a distinct species. The status of females of S. woolletti from Manipur and Siam that Evans (1949) listed and ssp. cephalina Evans, 1932 from Java needs to be reexamined.
