The classification presented here follows Masner (1993) with minor
updates e.g. Taekal et al. (2014) transferred Psix and
Paratelenomus from Telenominae to Scelioninae. A comprehensive
phylogenetic assessment based on both morphological and molecular data to
formulate a revised classification of Platygastroidea is still required.
Murphy et al. (2007) conducted a molecular phylogenetic analysis of the
entire Platygastroidea in which the Platygastridae was supported as a
monophyletic group nested within Scelionidae. As a result the
Scelionidae were retrieved as polyphyletic, but the classification was
not revised because of low support for many of the deeper nodes in the
cladogram, and inadequate taxon sampling (less than a quarter of the
valid genera in the superfamily were included in their analyses). Based
on the results of Murphy et al. (2007), Sharkey (2007) formally
synonymised Scelionidae with Platygastridae. Subsequently McKellar &
Engel (2012) raised the tribes Sparasionini and Nixonini to family level
and recognized four families:
Sparasionidae, Scelionidae and Platygastridae,
but in Ortega-Blanca et al. (2014) they treated placement of these
two tribes within the Platygastroidea as incertae sedis
recognizing only two families: Scelionidae and Platygastridae. These higher
classification changes made by Sharkey (2007) and McKellar & Engel
(2012) have largely not been accepted (Talamas & Buffington, 2015;
Popovici et al. 2017) and until robust phylogenetic data is published
the classification of Masner (1993) is followed.
