The Zoological Institute of the Russian Academy of Sciences serves as the repository for a large number of primary and secondary types of species described by the late Mikhail Kozlov. Recent travel to this museum to study Kozlov's primary types of Trissolcus Ashmead offered the opportunity to assess type material for all of Platygastroidea in the Zoological Institute, revealing that the classification for a modest number of taxa requires adjustment. Revisionary work on Trissolcus will occur in a future monograph, and we here treat Platygastroidea exclusive of this genus. For completeness, the holotypes of species subsequently described by Peter Buhl in two of Kozlov's genera, Pyrgaspis and Anirama, were examined and Buhl's diagnostic characters are here photographically illustrated.
Two of Kozlov's platygastrine genera, Pyrgaspsis and Stosta, were established for species with atypical shapes of the mesoscutellum, whereas these species otherwise fit easily into the broad concepts of Platygaster and Synopeas, respectively. Similarly, Anirama was described for a species in which the apical male antennomere is elongate and Criomica for a species with a slightly unusual head shape. Such description of genera for apomorphic species brings attention to unusual morphologies, but is detrimental to the construction of a natural classification if it renders other taxa polyphyletic.
In our perspective, the most needed contribution to classification in the Platygastrinae is detailed character analysis, evaluation of monophyly for existing genera, and placement of species into monophyletic species-groups. We do not consider the characters that Kozlov used to designate new platygastrine genera to indicate lineages separate from Platygaster and Synopeas, but they are potentially useful for species-group classification. It is our hope that the characters, treatments and illustrations presented here will contribute to this cause.
Examination of Kozlov's specimens revealed him to be, in our opinion, a “splitter” as opposed to a “lumper,” that is, he tended not to treat morphological differences as intraspecific or intrageneric variation. A benefit of Kozlov's species concepts is that series identified by him are morphologically uniform. Because of this, we are confident that the paratypes and holotypes of Kozlov and Lê are conspecific. We here treat one of their species, Paridris macrurous, as a junior synonym of Paridris bispores based on a paratype specimen.

Collection data for all specimens are available in the Hymenoptera Online Database (http://purl.oclc.org/NET/hymenoptera/hol) by entering the specimen identifier (CUID) in the search form. CUIDs for all specimens are presented in the material examined section of each taxonomic treatment and may be identified as a collection coden followed by a number (note capitalization and the space that follows some acronyms). The locality data reported for primary types are not literal transcriptions of the labels: some abbreviations are expanded and additional data from the collectors may be included.
Images were produced using a Microvision Instruments imaging system with Cartograph software, a Z16 Leica lens and a JVC KY-F75U digital camera. Single montage images were produced from image stacks with the program CombineZP. In some cases, multiple montaged images were stitched together in Photoshop to produce larger images at high resolution and magnification. Full resolution images, and additional photographs of the specimens treated here, are archived in the Hymenoptera Online Database (http://purl.oclc.org/NET/hymenoptera/specimage) and MorphBank (http://www.morphbank.net).

Rajmohana and Veenakumari (2011) stated that the mesoscutellar spines of Dvivarnus punctatus differ from those of Gryonoides based on their location on the mesoscutellum. We agree, and more specifically, the mesoscutellar spines of Gryonoides proximally abut the axillula and are derived at least in part from striations of the scutoscutellar sulcus (Fig.
Kozlov described Anirama as a genus separate from Platygaster because the apical antennomere of the male is elongate. There are otherwise no characters to indicate that this lineage is distinct from Platygaster and we consider this antennal morphology to be apomorphic within Platygaster.

The separation of Criomica from Platygaster was justified on the basis of the shape and proportions of the head. The eyes are somewhat triangular, but otherwise the cephalic shape of Criomica is unremarkable. The 3-merous clava in the female of this species is notable and may be a useful character for future species-group placement.

Kozlov considered Pyrgaspis to be closest to Synopeas, presumably because of the pointed mesoscutellum, and he separated these genera based on the orientation and height of the mesoscutellar spine. However, the widely separated lateral propodeal carinae (propodeal keels) (Fig.

Kozlov’s treatment of Stosta was essentially identical to that of Pyrgaspis in that the description of a new genus was performed to accommodate the shape of the mesoscutellum. As in Platygaster, a broad range of mesoscutellar forms can be found in Synopeas (Figs
