Description. Head black, a small spot behind posterior margin of eye brownish. Tips of mandibles and anterior margin of labrum often brownish. Antennomere 1 orange with darkened dorsal side, antennomeres 2 to 4 orange, the rest black. Pronotum black with anterior angles brownish (rarely there is a brownish stripe along the lateral parts of anterior margin, also posterior angles sometimes brownish). Scutellum black. Elytra bicolorous, the anterior half including epipleurae orange with a small round black spot near suture at the first third of elytral length, the posterior margin of orange pattern irregular, oblique, posterior half of elytra black. Legs and the underside black, trochanters and apices of fourth tarsomeres sometimes brownish.

Measurements. Males: 8.20–8.75 mm; females: 6.90–8.50 mm (holotype: 7.40 mm).

Male ( Fig. 8 ). Labrum transverse, anterior margin widely shallowly incised, the lateral parts of anterior margin with short pale hairs, several longer hairs also on the disc of labrum. Head semiopaque. Anterior part of head covered with fine punctures, almost glabrous. Frons very broad, 3.7 times as wide as the diameter of the eye, with a round shallow impression in the middle, densely covered with relatively large punctures and short recumbent hairs. Vertex finely punctured, with dense long pale hairs. Antennomere 1 clavate, anteriorly covered with longer hairs, antennomere 4 small, triangular, antennae distinctly serrated from segment 5.

Prothorax transverse, 1.70 times as wide as long, widest at two thirds, moderately convex, covered with sparse large punctures mixed with very fine, on the disc almost invisible, punctures, lustrous. Lateral margins moderately rounded, convergent anteriad, anterior margin slightly concave, posterior margin slightly rounded, thickened in scutellar area, distinctly sinuated before thickening. Anterior angles rectangular with shortly rounded tip, posterior ones obtuse, with distinct tip, all angles bears one pale seta. All margins bordered (lateral margins relatively widely), except the middle part of anterior margin where the border disappears. Scutellum triangular with rounded apex, lustrous, laterally with distinct punctures.

Elytra cylindrical, 1.65–1.75 times as long as wide at the humeral part, glabrous, lustrous, densely covered with small fine confused punctures dissappearing in elytral apices.

Tarsi broad. First protarsomere transverse, 1.35 times as broad as long, 0.45 times as long as two following tarsomeres combined.

Aedeagus as in Fig. 20 .

Female. Tarsi more slender, first protarsomere as wide as long, 0.55 times as long as the two following tarsomeres combined. Spermatheca and rectal sclerites as in Figs. 32 , 43 .

Differential diagnosis. P. intersecta is well defined by its characteristic coloration. The only similar Paraclytra species, yet much smaller, is P. minuta where the orange pattern on elytra is reduced to humeral area ( Fig. 9 ). Both species differs also by the structure of the aedeagus ( Figs. 20–21 ).

Distribution. Benin, Guinea, Nigeria, Sierra Leone. Lacordaire (1848) reported it also from „Caffrerie“ [ South Africa], what is evidently false record.
