Description. Coloration. Head between and behind eyes chestnut brown, vertex with one or three small paler spots, head before eyes honey yellow, antennae sepia to sienna, more or less distinctly paler annulated. Prothorax honey yellow, pronotum with reverse W-shaped, sienna to chestnut brown spot in middle. Meso- and metasternum, scutellum, legs and ventral part of abdomen honey yellow. Elytra honey yellow, mottled with chestnut-brown marks.

Male. Eyes of moderate size, protruding, head across eyes moderately narrower than pronotum, temples straight and convergent posteriorly.Antennae slightly exceeding elytral midlength. Surface of head very finely imbricate-punctate, finely yellow pubescent, matt. Pronotum distinctly wider than long, its anterior margin together with anterior corners and lateral margins rounded, posterior corners nearly sharp, protruding, posterior margin widely rounded. Surface of pronotum sculptured and pubescent like that of head, matt. Elytra moderately dilated posteriorly, elytral nervation almost invisible, surface of elytra very finely and densely punctate, with fine and semi-recumbent yellow pubescence and sparse small grooves bearing brown erect setae, matt and velvety. Aedeagus as in Figs. 61 and 64 , apex of paramere mostly depressed and concave (possibly an artefact).

Female. Eyes slightly smaller than in male, antennae shorter, hardly reaching elytral midlength. Pronotum ca 1.3 times as wide as long, elytra wider than in male.

Length J ♀: 9.7-12.5 mm.

Differential diagnosis. Stenothemus holosericus sp. nov. belongs to the S. harmandi species group. It differs from other species by the characters mentioned below in the key.
