3. Stenaptinus consularis ( Schmidt-Göbel, 1846)

Figs 5, 8 , 15, 18 , 31–34 , 57, 60 , 90–94 .

DIAGNOSIS. Elytra slightly wider apically than basally, with humeri more or less widely rounded and rather distinct. Dorsal pattern ( Figs 90–94 ): black patch on vertex small Vshaped, narrow to missing; pronotum black, with yellowish spots narrow and separate, to yellow, with base, apex and lateral beads black; elytral transverse band from narrow, more or less dentate, isolated from lateral margin, to wide and laterally extended to widely pale apical margin. Tergite VII with 9–14 strong and straight apical setae in female, sternite VII bi- to quadrisetose in male. Aedeagus ( Figs 31–34 ) similar to that of S. lissoderus , except that apex of median lobe is blunt and the internal sac has larger basal bulbs: proximal bulbs and left distal bulb being very large, and right distal bulb rudimentary yet very distinct (vs. missing). Female gonocoxite IX ( Fig. 57, 60 ) and reproductive tract as in S. lissoderus .

GEOGRAPHIC DISTRIBUTION. Northern India and northern Indochina, including Myanmar and Thailand east to northern and central Vietnam. The species range is similar to that of S. stenoderus yet not quite clear, since confusion of the two species occurred based on Chaudoir’s [ Chaudoir, 1876] supposion of their synonymy. Bates [1892] shared and Andrewes then [ Andrewes, 1923, 1924] confirmed this supposition, while the latter author occasionally used the junior synonym for the species [ Andrewes, 1924].

COMMENTS. The adults from all examined Vietnamese populations of the species are constantly different from the other ones in body shape, proportions, and colour pattern, the latter being almost invariable, which is largely uncharacteristic of the genus. This seems to me sufficient to describe a new subspecies.
