Specimens examined.

Vietnam: Mt. Tam Dao , Vinh Phuc Prov., 10.V.1996 (KSCJ, 2 males) .

Additional description.

Male. Antennomeres V-X with an area vested with sensilla basiconica at apical margin in ventral view; XI without pit-like sensillum. Elytra with two large callous areas at base. Tarsal pulvillar formula 4-4-2; protarsomeres I and II with large lobed pulvilli; III and IV with large bilobed pulvilli; mesotarsomers I with vestigial minute pulvillus; II with small lobed pulvillus; III and IV with small bilobed pulvilli; metatarsomeres I and II without pulvilli; III and IV with small bilobed pulvilli.

Abdominal sternite V almost transverse. Pygidium weakly emarginated at apical margin (Fig. 36 ); apical margin of ventrite VI (Fig. 37 ) emarginated at middle; spicular forked, long (Fig. 38 ).

Tegmen (Fig. 39a-c ) with dorsal and ventral sinuses at apical 1/6 of total length; tegminal arms long, extending 1/3-2/3 of total length. Median lobe (Fig. 40a-c ) longer than tegmen; plate simple, without denticles.

Remarks.

This species was originally described based on a single female specimen from India. In this paper, we describe the male in detail. This species is also related to Hemitrachys bizonatus Gorham, 1876 based on the structure of the male genitalia.

Distribution.

India. New record: Vietnam.
