Eupelmidae of Iran includes 31 species and seven genera in two subfamilies of Calosotinae and Eupelminae. Within the reported species, Anastatus Motschulsky, 1859 belongs four species: A. bifasciatus Geoffroy, A. dlabolai Kalina, A. tenuipes Bolivar y Pieltian and an unknown species. These species associated mostly with some lepidopterous species. Recently another species was found within collected specimens on Tamarix in East-Azarbaijan province, Shabestar. This specimen was collected via sweeping net in 25.x.2015. It was identified as Anastatus catalonicus Bolivar y Pieltain, 1935 which was deposited in the insect collection of the Department of Plant Protection, East-Azarbaijan Research Center for Agriculture and Natural Resources, Tabriz, Iran. This species known from Bulgaria, France, Germany, Romany and Spain. It was reported as a parasitoid Lymanteria dispar L. (Lep.: Lymanteridae) and eggs of Iris oratoria (L.) (Mantidae). Most important morphological characters of this species are antennal flagellum plus pedicel 1.7-1.8 times as long as breadth of head; scrobes separated from anterior ocellus by slightly more than a diameter of ocellus; macropterous with forewing about 2.0 times length of metatibia, forewing with white transverse band strongly constricted medially, occasionally narrowly divided into two subtriangular spots; ovipositor sheath extending beyond last tergite for a distance less than half length of metabasitarsus. Female A. maculosus most closely resemble A. catalonicus, the two species having similar thoracic sculpture with the median lobe of the mesoscutum strongly reticulate and relatively dull and the posterior depressed area partly smooth and shiny. The white transverse band on the forewing of female A. catalonicus is medially constricted and occasionally completely divided by a narrow infuscate bridge, but in A. maculosus the two white spots derived from the transverse band are always well-separated. Female A. maculosus has a longer ovipositor sheath and shorter antennal scrobe than A. catalonicus, and the antennal toruli are slightly higher on the face. Males of the two species are very distinct, the forewing of A. maculosus being patterned as in the female but that of A. catalonicus being clear; in addition, the antennal scape, maxillary palp and metatibia of A. maculosus are brownish whilst these parts in A. catalonicus are more or less marked with yellow.
