Description of holotype.

Body measurements in mm¡ TL 4.1, EW 2.3. Body shiny black with reddish-brown elytral patterns, oblong oval, maximum width posteriorly to its middle ( Fig. 1 ). Antennae with 11 antennomeres, dark brown; antennal club consisting of 2 antennomeres, clearly distinct, ovate and much broader than other antennomeres, covered by hardly visible procumbent pubescence and few solitary setae [antennae not complete] ( Fig. 4 ). Ocellus on front present. Pronotum shiny black, quite densely and coarsely punctate (as head), almost twice as wide as long, narrowed anteriorly, broadest in its apical part, its distinct lateral margins completely visible from above; cuticle between punctuation shiny, covered by yellowish-grey, short, recumbent pubescence. Posterior angles almost rectangular, with rounded edge, completely visible from above; anterior angles obtusely angulate and also visible from above ( Fig. 3 ). Elytra with much finer punctuation compared to pronotum, space between punctures bigger than puncture diameter; cuticle shiny, reddish-brown in anterior 1/4, other part black, with very short recumbent black microsetation. Epipleuron, short, reddish-brown. Prosternum and metasternum with short, yellowish setation. Abdominal visible ventrites black, with yellowish, short, recumbent setation, punctures in the middle sparse and fine, but increasing strongly in density and roughness towards lateral margins. Legs light brown, tibiae with small spines ( Fig. 5 ).

Male unknown.

Differential diagnosis. The new species is very similar to Hemirhopalum brasiliense Herrmann & Háva, 2013 but differs from it by the anterior reddish-brown part of elytra (orange-yellow anterior part with apical spot in brasiliense ); from Hemirhopalum bicolor Sharp, 1902 differs by the 1/4 anterior reddish-brown part of elytra (3/4 yellowish part in bicolor ). From all other species within the genus differs by the characteristic elytral colour and structure of antennae.
