Carpenter (1991) presented a phylogenetic analysis of genera of Polistinae, with Synoeca placed as sister-group of Clypearia (= Occipitalia; synonymized with Clypearia by Carpenter et al., 1996), Asteloeca and Metapolybia, but the interrelationships among the latter genera were unresolved.
Carpenter's (1991) analysis of generic relationships in Polistinae, based on morphological characters, established a monophyletic group comprising Asteloeca, Clypearia (= Occipitalia) and Metapolybia, based on the anterior pronotal carina raised (in our matrix as character 10), but did not resolve the interrelationships among these three taxa.
Synonymy of the genus Occipitalia Richards, 1978, with Clypearia de Saussure, 1854 (Hymenoptera: Vespidae; Polistinae, Epiponini).
