Description.
Male. Length. 6.2-6.4 mm, width 4.0-4.2 mm.
Head, pronotum, elytra, and legs yellow, antennae and ventral surface of body yellowish brown, scutellum brown; pronotum with a black spot on each side; each elytron with seven black spots, basal, middle and subapex with one pair of spots and apex with one spot.
Vertex finely and sparsely covered with punctures; frontal tubercles distinctly raised and separated from each other by a deep furrow; antennae short, robust, extended to the middle of elytra; antennomeres 1-3 thin, shiny; antennomeres 4-11 wide and flat, with short hairs, segment 4 approximately twice as long as wide; antennomeres 5-10, each approximately 1.6 × as long as wide; antennomeres 2 and 3 shortest, antennomere 3 nearly equal in length and shape to antennomere 2, antennomere 4 longest, twice as long as antennomeres 2 and 3 combined; antennomeres 5-10 gradually shortened, shorter than 4; antennomere 11 slightly longer than 10, pointed.
Pronotum approximately 2.5 × as wide as long, with rounded lateral margins; disc slightly depressed on each side, sparsely covered with small punctures, with the punctures on pronotum larger than those on the head.
Scutellum triangular, sparsely covered with small punctures.
Base of both elytra wider than pronotum, gradually widen posteriorly and rounded at apex; dorsal surface slightly convex, irregularly covered with large and deep punctures, the interstices between punctures slightly wider than diameter of individual punctures.
Metasternum 2.5 × as long as mesosternum; prothoracic legs shortest, mesothoracic legs slightly longer, metathoracic legs longest.
Ventral surface of abdomen with five segments, segment 1 longest, segments 2-4 gradually shortened, apical segment slightly longer than segment 4, three lobes.
Aedeagus slender, parallel-sided, basally widened, apex rounded. In lateral view strongly bent.
Differential diagnosis.
This species can be distinguished from other species by black spots on the elytra. This species closely resembles Sphenoraia (Sphenoraioides) nebulosa , but the latter is without punctures in the scutellum.
Distribution.
China: Guangdong.
