Bionomics.

Unknown.

Differential diagnosis.

In some ichneumonid collections, this species has been confused with E. shikokuensis . However, E. multidens stat. rev. can be distinguished from E. shikokuensis by shallow concavity of proximal outer mandibular surface (Fig. 29B, D) (proximal outer mandibular surface with very wide subtriangular concavity in E. shikokuensis, as in Fig. 44B, D); separated proximal and distal sclerites (Fig. 29F) (proximal and distal sclerites usually confluent, as in Figs 7B, 44F, or rarely separated, as in Fig. 7A, in E. shikokuensis); stouter, shorter, and evenly narrowed mandible (Fig. 29B, D) (mandible much longer, slender, proximally strongly narrowed, and apical 0.7 parallel-sided in E. shikokuensis, as in Fig. 44B, D); narrower lower face (Fig. 29B) (lower face wider in E. shikokuensis, as in Fig. 44B), etc.

This species is also similar to E. combustus, and Uchida (1955) synonymised E. multidens stat. rev. under E. combustus . However, they are morphologically easily distinguished by body colour pattern (i.e., body entirely testaceous in E. multidens stat. rev., as in Fig. 29A, but body with black marks in E. combustus, as in Fig. 13A), and DNA barcodes also separate them. Hence, we revise the status of E. multidens stat. rev. as a valid species.
