Description.

Female (holotype).

Head. In dorsal view, 1.9 times as wide as its median long, 1.4 times as wide as mesoscutum, smooth, with temple rounded behind eyes (Fig. 1F). Eye in lateral view 1.4 times as high as wide and 1.7 times as wide as temple medially (Figs 1B, 2A). POL 1.6 times OD; OOL 3.0 times OD (Fig. 1F). Face 1.9 times as wide as high; inner margins of eyes subparallel (Fig. 1E). Clypeus 2.5 times as wide as high, slightly curved ventrally (Fig. 1E). Paraclypeal fovea reaching inner margin of eye (Fig. 1E). Mandible 3-dentate, weakly widened towards apex, 1.3 times as long as its maximum width. Upper tooth distinctly shorter then lower tooth, very small and rounded; middle tooth rather long and narrow, longer than lower tooth, pointed apically; lower tooth widest, rounded, distinctly moving downwards (Fig. 1C). Antennae 17-segmented, 0.8 times as long as body. Scape 2.4 times longer than pedicel. First flagellar segment 3.3 times as long as its apical width, 1.3 times as long as second segment. Second flagellar segment 2.2 times as long as its maximum width; third to twelfth segments about 1.8 times as long as their maximum width, 13th and 14th segments 2.0 times, and 15th (apical) segment 2.5 times as long as their wide accordingly (Fig. 1D).

Mesosoma. In lateral view, 1.2 times as long as high (Fig. 2A). Mesoscutum (dorsal view) 0.8 times as long as its maximum width, smooth, with two lines of sparse setae along tracks of notauli (Fig. 2B). Notauli mainly absent on horizontal surface of mesoscutum (Fig. 2B). Mesoscutal pit absent (Fig. 2B). Prescutellar depression smooth, without lateral carinae (Fig. 2B). Precoxal sulcus present, crenulate, not reaching anterior and posterior margins of mesopleuron (Fig. 2A). Posterior mesopleural furrow crenulate in upper half, smooth in lower half (Fig. 2A). Propodeum with pentagonal areola delineated by distinct carinae (Fig. 2C). Propodeal spiracles relatively small (Fig. 2C).

Wings (Fig. 2F). Length of fore wing 2.7 times as long as its maximum width. Radial (marginal) cell ending at apex of wing, 4.0 times as long as its maximum width. Vein r2 (3-SR) 2.3 times as long as vein cuqu1 (2-SR); vein r3 (SR1) 2.5 times as long as vein r2 (3-SR). Nervulus (cu-a) distinctly postfurcal. Brachial (subdiscal) cell closed distally, 3.0 times as long as its maximum width. Hind wing 6.5 times as long as its maximum width.

Legs (Fig. 2E). Hind femur claviform, 4.0 times as long as its maximum width. Hind tibia weakly widened towards apex, 9.7 times as long as its maximum subapical width, 1.5 times as long as its hind tarsus. First segment of hind tarsus twice as long as second segment.

Metasoma. First tergite long, slightly widened towards apex, 2.6 times as long as its apical width, finely rugose-striate in apical half (Fig. 2D). Ovipositor 1.2 times as long as first tergite, 0.4 times as long as metasoma, 0.9 times as long as hind femur, 0.2 times as long as fore wing (Fig. 2E).

Colour. Body, antenna, and pterostigma dark brown. Mandibles and legs yellowish brown. Wings hyaline. Length. Body 1.8 mm; fore wing 2.0 mm; hind wing 1.8 mm. Variation. Antenna 16-17-segmented.

Male. Unknown.

Etymology.

Named after Isfahan, the type locality of new species.

Comparative diagnosis.

This new species is similar to Aspilota compressiventris Stelfox & Grahan, 1951 (Austria, Hungary, Russia, and U.K), Aspilota makita Papp, 2008 (Hungary and Romania) and Aspilota spiracula Munk & Peris-Felipo, 2013 (Denmark). All these species have the propodeum with a pentagonal areola delineated by a distinct carinae. However, Aspilota isfahanensis sp. n. differs from Aspilota compressiventris in having the mandible 1.3 times as long as its maximum width (1.7 times in Aspilota compressiventris ), the first flagellar segment 3.3 times as long as its maximum width (4.0 times in Aspilota compressiventris ), the hind femur 4.0 times as long as its maximum width (4.5 times in Aspilota compressiventris ), the first metasomal tergite 2.6 times as long as its apical width (3.0-4.0 times in Aspilota compressiventris ), the face 1.9 times as long as high (1.5 times in Aspilota compressiventris ), and the head in dorsal view 1.9 times as long as long (1.5 times in Aspilota compressiventris ). The new species differs from Aspilota makita in having the mandible 1.3 times as long as its maximum width (1.7 times in Aspilota makita ), a hind femur 4.0 times as long as its maximum apical (3.2 times in Aspilota makita ), the first metasomal tergite 2.6 times as long as its apical width (2.0 times in Aspilota makita ), a propodeum with the areola distinctly delineated by carinae (areola less distinctly delineated in Aspilota makita ), the first flagellar segment 3.3 times as long as its maximum width (4.0 times in Aspilota makita ), and the upper tooth rounded (pointed in Aspilota makita ). Finally, Aspilota isfahanensis sp. n. differs from Aspilota spiracula in having the mandible 1.3 times as long as its maximum width (1.5 times in Aspilota spiracula ), the eye in lateral view 1.7 times as wide as the temple medially (nearly as long in Aspilota spiracula ), the first flagellar segment 3.3 times as long as its maximum width (2.5 times in Aspilota spiracula ), middle flagellar segments 1.8-2.2 times as long as their maximum widths (1.0-1.1 times Aspilota spiracula ), the first metasomal tergite 2.6 times as long as its apical width (2.3 times in Aspilota spiracula ), and a long metasoma (short in Aspilota spiracula ).
