Bayesian-likelihood inference phylogenies based on cytochrome oxidase I (COI) and ribosomal DNA (28S) sequences in seed-specialized wasps of the Megastigmus genus. A Short fragment COI (34 taxa, 417bp) B Long fragment COI (31 taxa, 810pb) C Nuclear fragment (33 taxa, 924pb). Torymus azureus Boheman, 1834 was used as an outgroup. Posterior probability values are indicated at each node. New taxa described in this paper are indicated in red and bold. Branches of taxa associated with Anacardiaceae as host plant family are in blue, and branches of taxa associated with Cupressaceae are in green.
