Type locality. Sultanate of Oman, Ash Sharqiyah South Governorate, 27km southwest of RasAl Hadd town , 22°19'7"N, 59°37'38"E, 50 m a.s.l.

Holotype, ♀, (CPG), ‘ Oman, Ash-Shar. S. Gov. [Ash-Sharqiyah South Governatore] / Ras Al Hadd 27km SW [southwest] / 22°19'7"N, 59°37'38"E / 7.III.2023, at light / L. Bobot leg.’.

Paratype, 1 ♀, (CBO), same data as holotype .

All specimens were provided with an additional red printed label: ‘ HOLOTYPUS [or PARATYPUS respectively] / DICRONYCHUS / boboti n. sp. / Platia-Konvička’.

Diagnosis. – A species with impressed v-shaped lines at the posterior half of prosternum, it can be compared to D. brancuccii Platia & Schimmel, 2007 for the same shape of the intermediate sclerite of bursa copulatrix but morphologically is distinct for the more frail body and particularly the finer punctuation of pronotum.

Description of the holotype

Coloration. – Moderately shiny; head, pronotum scutellum a darkferruginous, elytra lighter, entirely yellow-ferruginous or with blackish halos on the disk; antennae and legs yellowish; covered with dense, particularly on elytra, recumbent and yellowish pubescence.

Head. – Frons flat, very slightly impressed before the anterior margin, this ridged, moderately and regularly arcuate projecting above the clypeus; fronto-clypeal space not restricted;punctuation very dense, with punctures approximately of the samesize, contiguousor withshortest intervals.– Antennae (Fig. 6) short, just exceeding the middle of pronotum very slightly serrated from the third article on; second article sub-conical a little shorter than the third, third-tenth sub-triangular, gradually slenderer and subequal in length, last long as the previous, sub-ellipsoidal, symmetrically constricted at apex.

Pronotum. – 1.07-1.09x wider than long, widest at the middle, strongly convex without any depressions abruptly sloping at sides and base; sides very arcuate, widest in the middle, distinctly sinuate before the posterior angles, the latter short, slightly divergent, obliquely truncate at the apices with a very short carina gradually diverging from the sides; lateral suture-like margin well marked, sub-straight and reaching the anterior third; punctuation dense, double; larger, simple, punctures are regularly mixed with very fine punctures.

Scutellum . – Heart-shaped longaswide,impressedin the middle, pointed at apex and narrowly emarginate at middle of the base, very finely punctured.

Elytra. – 2.35-2.4x longer than pronotum and as wide as it at the base, convex; sides widest at the middle, regularly rounded at the apices; striae regularly marked and finely punctured; interstriae flat to sub-convex very finely punctured.

Prosternum. – Posterior half with impressed V-shaped lines running sub-parallel to the prosternal sutures.

Claws. – Feebly dilated in the basal half.

Bursa copulatrix. – Sclerified as in the Fig. 4.

Size. – Length 6.55-7.0 mm; width 2.06-2.25 mm.

Male. – Unknown

Etymology. – The species is dedicated to the collector Ludvík Bobot (Otrokovice, Czech Republic). Ludvík Bobot was a member of the entomological expedition to Oman.
