Aphid parasitoids of the subfamily Aphidiinae (Hymenoptera: Braconidae) of northeastern Iran were studied in this paper. A total of 29 species are keyed and illustrated with line drawings. The aphidiines presented in this work have been reared from 42 aphid host taxa occurring on 49 plant taxa from a total of 33 sampling sites. Sixty-six aphidiine-aphid-plant associations are presented. Trioxys metacarpalis sp. nov. from Chaitaphis tenuicaudata Nevsky (Hemiptera: Aphididae) on Kochia scoparia, is described. The species diversity based on the comparative faunistic analysis is discussed.

In this study, a total of 108 Aphidiinae species, belonging to 18 genera, associated with 240 aphid species in 16 countries of the Middle East and North Africa are reviewed. 743 host aphid-parasitoid associations are listed. New material was collected from various regions of Saudi Arabia during 2011–2013. Three species including Aphidius avenae Haliday, 1834, Aphidius platensis Brèthes, 1913 and Praon barbatum Mackauer, 1967 are first recorded for the fauna of this country. Lysiphlebus marismortui Mescheloff & Rosen, 1990 syn. nov. is classified as the junior synonym of Lysiphlebus confusus Tremblay & Eady, 1978. An illustrated up-to-date key to all known species of Aphidiinae that occur in the Middle East and North Africa is provided. The findings are discussed in relation to the overall parasitoid-aphid associations in the target investigated region.

An updated checklist of the scorpiofauna of Iran is presented. The checklist is based on records of scorpion species which their presence have been confirmed in Iran through field expeditions, examination of scorpion collections, literature review, and personal communications with researchers. According to the presented checklist the scorpion fauna of Iran consists of 68 valid species (41 endemic to Iran) belonging to 19 genera and four families and 6 doubtful reports (belong family Buthidae). Hemiscorpius gaillardi (Vachon, 1974) and Compsobuthus jakesi Kovařík, 2003 reported for the first time from Hormozgan province. Odontobuthus tavighiae Navidpour et al., 2013 collected for the first time from Fars province. Kraepelinia palpator (Birula, 1903) and O. tirgari Mirshamsi et al., 2013 were new records for South Khorasan province fauna. The list is dominated by members of the family Buthidae (58 species) with 85.3% of total species. The level of regional endemism exceeds 60.3%. A dichotomic identification key to the Iranian species on the basis of a DELTA database has been provided.

Morphometric analyses were carried out on five biotypes of Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae: Aphidiinae) associated with five host aphid species, Aphis craccivora Koch, Aphis fabae Scopoli, Aphis gossypii Glover, Brachyunguis zygophylli (Nevsky) and Melanaphis sacchari (Zehntner). Sixteen morphological characters were measured on female specimens of L. fabarum. Two multivariate discriminant analyses, discriminant function analysis and Unweighted Pair Group Method with Arithmetic mean cluster analysis, were employed to discriminate among L. fabarum biotypes on a morphological basis. Both discriminant function analysis and cluster analysis revealed significant morphological differences. Specimens of L. fabarum reared on Melanaphis sacchari/ Sorghum halepense association showed clear differentiation from other L. fabarum biotypes. A stepwise discriminant function analysis selected Distance between R1-R2 junction and outer margin of wing, Metacarpus length, Width of first tergit, Basal vein length and Femur length that showed the highest contribution to the separation of host-adapted biotypes. A dendrogram of the cluster analysis based on data of squared Euclidean distances classified biotypes in different groups. This study demonstrates that morphometric analysis of morphological characters can efficiently discriminate among host-associated groups based on size variation and clearly separate biotypes of L. fabarum. We concluded that L. fabarum biotypes are not homogeneous morphological entities, and represent different host-associated forms.

A survey on the fauna of the Cryptinae of Isfahan Province was carried out in the summer of 2012. Specimens were collected using Malaise traps and sweeping nets. Nine species belonging to 9 genera of Cryptinae occurring in Isfahan Province were collected and identified. Among them, 7 species have been recorded from Iran previously. These species are
