Eustenancistrocerus (Parastenancistrocerus) iranicus GUSENLEITNER nov.sp. ( Figs 6-9 )

H o l o t y p e: Iran, Fars, Larestan , 870m, 27°32’N 54°22’E, 3, 30.11.201 2, leg. A. Falahatpishe, coll. OLM. P a r a t y p e s: Same data as holotype, 13 ; Iran, Fars, Darab , 1124m, 28°42’N 54°34’E, 233, leg. A. Haghighi ; all in coll. Dept. Entom., Jahrom Branch, Islamic Azad Univ., Jahrom, Iran .

D i a g n o s i s: This species belongs to the group of Eustenancistrocerus (Parastenancistrocerus) amadanensis (DE SAUSSURE 1863) and is very similar to Eustenancistrocerus (Parastenancistrocerus) khuzestanicus GIORDANI SOIKA 1970 . But the species described here differs in the form of the last segments of the antennae ( Giordani Soika 1970, p. 98) and the second tergite is simply truncate and not extendedly rounded (fig. 10). The occipital carina narrowly lamellated but in P. kuzhestanicus not lamellated.

D e s c r i p t i o n: E. iranicus (fig. 6) is black with nearly white markings, distributed as follows: mandibles except for black teeth; labrum; clypeus; top part of face up to the ocelli; antennal scape; first and last segments of the flagellum; temples and pronotum completely; a dot on mesonotum in front of scutellum; mesopleurae nearly completely; tegulae except for two translucent dots and a translucent margin; parategulae; scutellum and postscutellum completely; two large and two small patches on each side of propodeum; legs; first tergite except for the front; an apical band on second tergite, attached to big patches at the sides; bisinuate apical bands on tergites 3 to 6; first and second sternites completely, and sternites 3 to 6 with bisinuate apical bands. Wings pale, without dusky parts.

Clypeus (fig. 7) wider than long (2,2: 1,7), emargination flat (length: depth = 1,5: 0,3), and broader than distance between antennal grooves (length: depth = 1,5: 1,2). Clypeus coarse and densely punctured, except for a sparsely punctured, narrow band at the base. Puncturation of frons, vertex and temples similar to that of clypeus. Antennal scapes glossy, with only a few microscopical punctures. Last segment of flagellum long and narrow (fig. 1). Pronotum, mesonotum, scutellum and mesopleurae much more coarsely punctured than face. Frontal border between horizontal and vertical part of pronotum lamellated like occipital carina. Postscutellum very finely sculptured. Propodeum with coarse punctures, only the concavity shows microscopical striation. Tegulae and legs glossy, without punctures.

Puncturation of first tergite very similar to that of scutellum; transverse carina with a central depression. Second tergite uniform and densely punctured. Third tergite densely punctured and indented in the middle (fig. 8, 10); other tergites more finely but not as densely punctured. In profile, second sternite flat, sloping steeply to the basal furrow, with dense, deep puncturation similar to that on second tergite. Tergites 3 to 7 more finely punctured than second tergite, with glossier intervals. The whole insect has a microscopical pubescense that is difficult to see.

Body length: 5 mm.

F e m a l e: unknown.

E t y m o l o g y: The name is derived from the country of origin, Iran.
