D i a g n o s i s: Pterocheilius persicus (fig. 1) is similar to Pterocheilus dives RADOSZKOWSKI 1876 (fig. 5), but differs in colouration; the pronotum is longer, the first tergite is stronger and the second sternite is more densely punctured than in P. dives . The occipital carina is lamellated in P. persicus .

D e s c r i p t i o n: Primary colour black, with yellow colouring distributed as follows: mandibles nearly completely, labrum, clypeus (except for translucent anterior margin), and orbital bands from sinus to clypeus; one small dot above the antennae; antennal scape except for apical end; big dots present on the temples and the dorsal surface of the pronotum; patches on the upper part of the mesopleurae; tegulae except for the translucent margins and the disk; two dots on scutellum; a transverse band on postscutellum; claps on the sides of the scutellum and postscutellum present to tegulae; two patches on the metanotum; legs (the base of femora III and the trochanters black except for small yellow dots); broad, laterally enlarged apical bands on first and second tergites; a bisinuate narrow band on third tergite; tergites 4 to 6 totally, and the first sternite and other sternites almost completely yellow. Three red spots present in the middle of second sternite (fig. 4). Wings pale, with dusky radial cells.

Clypeus (fig. 2) much broader than long (5,0: 3,0) and the straight „emargination“ is longer than distance between the antennal grooves. Disc of clypeus strongly punctured; spaces between the dots are glossy and similar in size to the punctures. Clypeus covered with microscopical white pubescence. Frons very densely punctured with small spots. Vertex and temples slightly punctured. On pronotum, mesonotum, mesopleurae and scutellum the dots are coarser and fewer than on the face. The posterior part of postscutellum has no punctures. Lateral edges of pronotum with spikes. Mesonotum has a prescutal furrow (extending from scutellum to close to middle of mesonotum). Propodeum sides rounded and uniformly punctured; only the lower part of each side is finely cross-striped. Discs of tegulae and legs glossy, without punctures.

Dots on the first tergite (fig. 3) not as coarse as those on mesonotum; the intervals between the dots have microscopical dots. Second tergite has a few, not very coarse, microscopical dots. Tergites 3 to 6 also have fine microsopical dots. Sternites 2 to 6 glossy, with scattered punctures (fig. 4).

Head and thorax with long, wavy, white hairs; abdomen with only microscopical pubescence.

Body length: 9 mm.

Male unknown.

Etymology: The name is derived from Persia, the area of origin.
