Bionomics.

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 View Figure 29 ) (proximal outer mandibular surface with very wide subtriangular concavity in E. shikokuensis , as in Fig. 44B, D View Figure 44 ); separated proximal and distal sclerites (Fig. 29F View Figure 29 ) (proximal and distal sclerites usually confluent, as in Figs 7B View Figure 7 , 44F View Figure 44 , or rarely separated, as in Fig. 7A View Figure 7 , in E. shikokuensis ); stouter, shorter, and evenly narrowed mandible (Fig. 29B, D View Figure 29 ) (mandible much longer, slender, proximally strongly narrowed, and apical 0.7 parallel-sided in E. shikokuensis , as in Fig. 44B, D View Figure 44 ); narrower lower face (Fig. 29B View Figure 29 ) (lower face wider in E. shikokuensis , as in Fig. 44B View Figure 44 ), 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 View Figure 29 , but body with black marks in E. combustus , as in Fig. 13A View Figure 13 ), and DNA barcodes also separate them. Hence, we revise the status of E. multidens stat. rev. as a valid species.
