Fifteen species belonging to ten genera of the encyrtid wasps (Hymenoptera: Chalcidoidea, Encyrtidae) were collected in southern Iran and are presented here with the host records. Four species are newly recorded for the Iranian fauna: Blastothrix aprica Sugonjaev, 1964; Psyllaephagus belanensis (Hoffer, 1963); Psyllaephagus pulchellus (Mercet, 1921) and Anagyrus archangelskayae Trjapitzin, 1972. Some new host associations were found for 10 encyrtid species. Two misidentifications were corrected. Available biological data as well as geographical distribution for each species are also included.

In the present study, which is based on the material collected from Southern part of Caspian Sea, Iran during 2013- 2016, one parasitoid species of the genus Coccobius Ratzeburg was identified as Coccobius pistacicolus (Yasnosh, 1968) (Hym: Aphelinidae). This species, which is reported for the first time from Iran, was collected in Rasht, Guilan province, and reared from Lepidosaphes pallida (Maskell) (Hem.: Diaspididae) on Ficus carica (Moraceae). Diagnostic characters of C. pistacicolus are provided.

In this survey, 116 species of 39 genera and 12 families from two sections Apiformes and Spheciformes of the superfamily Apoidea have been recorded from Georgia (Sakartvelo). Among them, one genus Polemistus de Saussure, 1892 and 39 species are new country records. This is just part of studied and collected material, therefore the identification continues.

The taxonomic status and placement of the Caucasian honey bee (Apis mellifera caucasica Gorbachev, 1916) (Hymenoptera: Apidae) remains puzzling, largely based on outdated investigations. After reviewing available scientific sources, we conclude that initially there was a confusing mismatch between the traditional geographical understanding of the Caucasus and the actual distribution of A. m. caucasica. Insufficient geographic sampling of honeybees across the Caucasus, a statistically inadequate number of studied samples, and incomplete research methodology are major drawbacks of previous studies. Morphometric reference data derived from an extremely limited number of samples still is in use as a standard for the identification of A. m. caucasica. It is highly probable, that this standard does not reflect true morphometric diversity, covering natural geographical variations, which most importantly hinder preservation or breeding efforts. To resolve these deficits, honeybees of the Caucasus and adjacent regions need to be studied in more detail with greater depth of sampling. A thorough study, using modern morphometric approaches and molecular genetic methods, is needed to characterize A. m. caucasica and produce a statistically robust dataset for due reconsideration of its taxonomic status and placement.
