A new species of Aspilota without mesoscutal pit, A. isfahanensis Peris-Felipo, sp. n., is described and illustrated from Iran. The new species is compared with its three morphologically most similar species, A. compressiventris Stelfox & Grahan, 1951, A. makita Papp, 2008 and A. spiracula Munk & Peris-Felipo, 2013, is provided. A key to the western Asian species of Aspilota is provided.
Alysiinae , Aspilota , new species, identification key, Palaearctic, Iran
The complex of genera that are closely related to Aspilota is the most taxonomically complicated group within the braconid Alysiinae, mainly because of their small body size and their reduced number of available diagnostic characters (
Information about Aspilota species from Western Asia is scarce, and only two species have been previously recorded, both from Iran (

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.
Mesosoma. In lateral view, 1.2 times as long as high (Fig.

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