DIAGNOSIS. See the key and description below.

DESCRIPTION. As for the nominotypical subspecies except the following: BL 15.6–19 mm. Dorsal pale pattern extensive (Figs 71, 93–94): entire head yellow, occasionally with a vague black V-shaped patch; pronotum yellow except base, apex and lateral margins; elytral humeral spot larger, elytral median fascia wide, reaching lateral margin, extended along side to a widely pale apical margin and also slightly basad, with lateral margin pale pale or narrowly infuscated in apical half. Sometimes 1–2 setules behind supra-ocular seta.

Pronotum barely wider, PW/PL 0.94–1.03 (1.0), and slightly larger, PW/HW 1.02–1.10 (1.05), broadest a third from apex, PLw/PW 0.27–0.41 (0.34); sides subsinuate a fifth from base. Base wider, PB/PA 1.08–1.15 (1.12), basal angles mostly very slightly obtuse and blunt.

Elytralong,EL/EW1.52–1.66(1.59),EW/EL1.56–2.08 (1.87).

Sternite VII mostly bisetose, sometimes trisetose, in male.

GEOGRAPHIC DISTRIBUTION. Northern and Central Vietnam from Nghe An to Kon Tum and Gia Lai provinces.

NAME. Refers to the entirely pale head as a distinctive feature of the new subspecies.

HABITATS AND HABITS. Of the specimens taken by the author, most were hand collected by floodland pools (often together with specimens of S. agnatus) and the other few on river banks. In the Kon Plong District, the adults were found to be frequent in close vicinity to a light-trap, but no specimen was attracted to the light.

COMMENTS. Two specimens, male and female, from Gia Lai Province belong to the new subspecies and match well the diagnosis, except that the former has color pattern more similar to that of the nominotypical subspecies. Hence the two specimens are not included in the type series.

At least two of totally three specimens mentioned in the description of Pheropsophus javanus v. ruficeps Jedlička, 1964, nom. nud. [Jedlička, 1964: 532], one from Laos and the other from central Vietnam, belong to this new subspecies rather than to any other species.
