Agathidini
Agathidini is a tribe of within the Agathidinae. Members are found primarily in Southeast Asia, with particular diversity in Thailand. The tribe has undergone significant taxonomic revision, with ten new described in 2017 to address previous issues of being placed in 'dumping ground' genera. Females lay inside early-stage of various , with developing internally and consuming the before it pupates.
