Two cuckoo wasp species (Hymenoptera: Chrysididae), Trichrysis lacerta (Semenov, 1954) from the subfamily Chrysidinae, and Cleptes striatipleuris Rosa, Forshage, Paukkunen & Soon, 2015 from the subfamily Cleptinae, are newly documented for the Iranian fauna. The specimens were collected using Malaise traps in the Fars Province, south of Iran during 2015-2016. Notes about taxonomy, relevant references as well as geographical distribution of both species are given. The total number of Iranian Trichrysis and Cleptes currently increased to four and three species, respectively.

In recent years, the research on the Iranian Chrysididae has been extremely prolific, thanks to the efforts of different teams. After the first checklist published by Rosa et al. (2013), more than one hundred taxa of cuckoo wasps have been recorded as new for Iran, including nine taxa described as new for science. Moreover, major modifications impacted the taxonomy of the family with two genera revaluated (Chrysellampus Semenov-Tian-Shanskij, 1932 and Colpopyga Semenov-Tian-Shanskij, 1954), Pseudochrysis Semenow, 1891 reintroduced for Pseudospinolia Linsenmaier, 1951; the description of the genus Morphochrysis Rosa & Pavesi, 2023 and several taxonomical changes to species level which were published and that deeply changed the first checklist, namely. As a consequence of all these fragmented changes, we propose a new, updated checklist of the Iranian species, to summarize all the new findings published in the last years. We describe eleven new species for science, Chrysis amerii Rosa & Farhad, sp. nov., C. chamrosh Rosa, sp. nov., C. crenulata Rosa, sp. nov., C. edentata Rosa & Baiocchi, sp. nov., C. peri Rosa & Baiocchi, sp. nov. and C. titanica Rosa, sp. nov. (succincta group), C. mediasignata Rosa, sp. nov. (leachii group), C. heimi Rosa, sp. nov. (maculicornis group), C. simurgh Rosa, sp. nov. (subsinuata group), Chrysura filidichroa Rosa, sp. nov. (dichroa group) and Hedychridium personatum Rosa, sp. nov. with its own new species-group. We report twenty-six new records of Chrysidinae for Iran: Chrysidea disclusa (Linsenmaier, 1959); Chrysis afghanica Linsenmaier, 1968; C. cylindrica Eversmann, 1858; C. echidna Semenov-Tian-Shanskij, 1967; C. grohmanni bolivari Mercet, 1902; C. klio Balthasar, 1953; C. laetula Semenov-Tian-Shanskij & Nikol'skaya, 1954; C. leuconoe Semenov-Tian-Shanskij, 1967; C. maracandensis Radoszkowski, 1877; C. mirabilis Radoszkovsky, 1877; C. mossulensis Abeille de Perrin-du Buysson, 1887; C. pseudobrevitarsis Linsenmaier, 1951; C. robertsi Rosa, 2020; C. rutilans Olivier, 1791; C. turcomana Semenov-Tian-Shanskij & Nikol'skaya, 1954; Chrysura laodamia laodamia (du Buysson, 1900); Euchroeus pellucidus (Radoszkowski, 1877); Hedychridium bytinskii Linsenmaier, 1959; H. mochii Strumia, 1994; H. plagiatum (Mocsáry, 1883); Hedychrum concinnum (Mocsáry, 1909); H. semicyaneum Mocsáry, 1889; Spinolia stchurovskyi (Radoszkowski, 1877); Spintharina extrema (Semenov-Tian-Shanskij & Nikol’skaya, 1954), and S. houskai (Balthasar, 1953). The current number of known taxa has therefore increased from 185 (179 species and 6 subspecies) to 315 (306 species + 9 subspecies). Hedychrum persicum Mocsáry, 1914 stat. nov. is upgraded to species rank. Chrysis chrysophora Semenow, 1892 and Hedychrum cyaneum Brullé, 1846 are considered nomina dubia and the latter as incertae sedis. Chrysis dawahi Strumia, 2012 is considered nomen nudum. The majority of chrysidid species in Iran (77.64%) are found exclusively in the Western Palearctic region. Among these, 21% are restricted to the Western Palaearctic. A thorough discussion is also provided on unreliable and doubtful species records.

The Iranian species of the genus Holopyga (Hymenoptera: Chrysididae) were investigated. Specimens were collected during four years of field research between 2010 and 2013, in northern and southern provinces of Iran. Twenty one species and subspecies were recognized, of which four species and one subspecies were recorded for the first time from Iran: Holopyga beaumonti Balthasar, 1953; H. fascialis Linsenmaier, 1959; H. ignicollis Dahlbom, 1854; H. inflammata inflammata (Förster, 1853) and H. jurinei Chevrier, 1862. Geographical distribution of all species and morphological diagnostic characteristics of the newly recorded species are given. The number of Holopyga species and subspecies in Iran is now raised to 21.
