Description. Head usually orange with a broad black band on the frons connecting both eyes, rarely the black band is interrupted in the middle or head is completely orange. Tips of mandibles, maxillary and labial palpes darkened. First four antennomeres yellow. Pronotum orange, rarely with two small obliquely elongated black spots laterally in the front of basal margin. The colour of scutellum varies from completely orange to completely black, often orange with black tip. Elytra orange, each elytron with 5 black spots (1, 1, 2, 1), the size of the spots is variable, two postmedian spots are sometimes connected forming an oblique band of irregular shape, usually not touching suture. The apical spots sometimes absent. Legs black, trochanters, bases of coxae, bases of tibiae (sometimes the basal half of tibiae) and the last two tarsomeres paler. Prosternum orange with a black spot at base behind procoxae, rarely with two black spots laterally or with the posterior half completely black. Meso-, metasternum and abdomen black.

Measurements. Males: 5.35–6.55 mm (lectotype: 5.85 mm); females: 5.55–7.15 mm.

Male ( Fig. 15 ). Clypeus lustrous, almost glabrous and very finely punctate. Frons broad, twice as wide as the diameter of the eye, shallowly impressed in the middle (sometimes impression indistinct). Vertex and frons densely punctate, semiopaque, covered with long pale hairs. Antennal segment 4 small, with triangularly extended apex, antennae distinctly serrated from segment 5.

Pronotum transverse, 1.65 times as wide as long, widest in the middle, moderately convex, almost impuctate, lustrous. Lateral margins slightly rounded, more convergent anteriad than posteriad, anterior margin slightly concave, posterior margin rounded and slightly enlarged in scutellar area. Anterior angles rectangular with rounded tip, posterior ones obtuse, widely rounded. Anterior margin thinly bordered, lateral and posterior margins more distinctly bordered. Scutellum subtriangular with truncate apex, lustrous, nearly impunctate.

Elytra cylindrical, 1.65–1.75 times as long as wide at the humeral part, glabrous, semiopaque, densely covered with rough confused punctures, the punctures cover also elytral apices.

Tarsi broader than in females. First protarsomere subtriangularly elongated, 1.3 times as long as broad, 0.5 time as long as the two following tarsomeres combined.

Aedeagus ( Fig. 26 ) with subtruncate apex and a small triangular process in the middle. Alae clavate and separated from each other.

Female. Tarsi narrower. Frons broader than in male, 2.50 times as wide as the diameter of the eye. Spermatheca and rectal sclerites as in Figs. 37 , 48 .

Differential diagnosis. By its habitus, Paraclytra traegaordhi resembles P. crocata , P. cervenkai sp. nov. and paler forms of P. sennariensis . All mentioned species can be easily distinguished by the structure of the aedeagus ( Figs. 16–17 , 22–24, 26 ). Due to relatively roughly punctured elytra the specimens of P. traegaordhi seem semiopaque while other mentioned Paraclytra species are lustrous. The colour characters are variable, although the colour of the head (usually orange with a broad black band from eye to eye on frons) and the presence of the black apical spot on the elytra could also help in determination of P. traegaordhi .

Distribution. Chad, Sudan.

Comments. The number of syntypes was not specified in the original description. The type series is currently divided into two parts deposited in ZMHB and NHRS. As a lectotype (present designation) we chose one male from ZMHB where the majority of Weise´s collection is deposited.
