Metapelmatinae
Bouček, 1988
Genus Guides
1Metapelmatinae is a of within Eupelmidae (Chalcidoidea), established by Bouček in 1988. It contains four : Metapelma, Neanastatus, Eopelma, and Lambdobregma. The subfamily is distinguished from Calosotinae and Eupelminae by structural features of the , particularly those related to the mesosoma and metasoma. Its phylogenetic relationships within Eupelmidae remain unresolved; Eupelmidae as a whole may represent a grade-level group united by convergent adaptations for jumping rather than shared ancestry.

Identification
distinguished from Calosotinae and Eupelminae by combinations of structural features including mesoscutal and scutellar-axillar complex . Gibson (1989) provides a key to separate the three eupelmid and distinguish them from Tanaostigmatidae and other Chalcidoidea. Within Metapelmatinae, are distinguished by features of the pronotum, , and metasomal structure.
Similar Taxa
- CalosotinaeShares Eupelmidae; distinguished by structural features of the mesoscutum and scutellar-axillar complex, with Gibson (1989) providing diagnostic key.
- EupelminaeShares Eupelmidae; distinguished by structural features, though exact diagnostic characters require examination of specific character states detailed in Gibson (1989).

Taxonomic History
Bouček established Metapelmatinae in 1988. Gibson's 1989 revision recognized four : Metapelma Westwood, Neanastatus Girault, Eopelma (new genus with type E. mystax), and Lambdobregma (new genus with Lambdobregma schwarzii comb. nov.).
Phylogenetic Uncertainty
No derived character states uniquely support Metapelmatinae, Eupelmidae, or Eupelmidae + (Tanaostigmatidae + Encyrtidae) as definitively monophyletic. Relationships among the three eupelmid remain unresolved based on available morphological evidence.
