Description. Body length: 4.10 mm. Body dark auburn ( Fig. 2A–C View FIGS 2 ), prothorax and elytra with both, bowed, light brown, pointed and raised, clubbed, elongate scales, more than four times longer than wide, rounded apicad. Rostrum shorter than pronotum, ( Fig. 2C, D View FIGS 2 ); in dorsal view weakly narrowed just behind antennal insertion, widening anteriad, and towards frons. Underside of rostrum with median tooth on submentum just posterior of mouthparts. Funicular antennomeres subequal (2 nd and 3rd) or transverse (4th to 7th). Club of antennae egg-shaped ( Fig. 2J View FIGS 2 ). Ocular lobes weakly pronounced ( Fig. 2D View FIGS 2 ), set with teeth ( Fig. 2E View FIGS 2 ). Prothorax about as long as wide (L/B: 1.06) ( Fig. 2A View FIGS 2 ), strongly constricted before fore margin; dorsal surface with coarse, polyhedric punctures separated by broad ridges ( Figs 2A View FIGS 2 ). Basisternum raised and set with two raised apically flattened spines ( Fig. 2F View FIGS 2 ). Procoxae subcontiguous; mesocoxae separated by their diameter; metacoxae separated by less than twice their diameter ( Fig. 2B View FIGS 2 ). Externally visible part of scutellum small and pentagonal ( Fig. 2I View FIGS 2 ). Elytra elongate (L/B: 1.7), dorsally widest at shoulders, attenuate from there to apex, hind wings present. Intervals as wide as striae, uneven elytral intervals weakly raised; raised (uneven) intervals on elytra with regularly arranged clubbed-elongate raised scales and shorter, pointed recumbent scales; even intervals with irregularly arranged clubbed-elongate scales. Each puncture of striae laterally with a small granule and thin recumbent bristle at anterior margin. Meso-, metaventrites and abdominal ventrites weakly punctate; each puncture with a clubbed and bowed, yellowish scale ( Fig. 2B View FIGS 2 ). Legs slender, femora clubbed, profemora with sharp ventral tooth ( Fig. 2C View FIGS 2 ). Tarsi with bilobed third tarsomere; claws free. Penis broad shovel-shaped, tip obtuse-angled, dorso-ventrally flattened, with four huge internal sclerites forming an arrow-like shape with two tube-like sclerites reaching in a curl far beyond apodemes ( Fig. 6D–F View FIGS 6 ). Female unknown.

Derivation of name: This species is named “bispinosus ” after the conspicuous apically flattened double spines on the basisternum.
