Abstract

The Agathidini (Braconidae: Agathidinae) genera of Southeast Asia are revised based on a phylogenetic analysis of COI and 28S. Ten new genera are proposed, i.e., Agathigma, Asperagathis, Chimaeragathis, Cymagathis, Liragathis, Leuroagathis, Scabagathis, Trochantagathis, Xanthagathis, and Zosteragathis. An illustrated key to the Southeast Asian genera of this tribe is presented. Species from Thailand are keyed and described for all genera of Agathidini except Bassus and Zosteragathis which have too many species for this publication and will be dealt with separately. The phylogenetic analyses indicate that Bassus s.s. is polyphyletic. However, there are no morphological characters to support this and we have retained the current concept of Bassus, which is basically those Agathidini with simple tarsal claws. Numerous new combinations are proposed based on species that are moved to the newly erected genera.

Highlights

Agathidinae is a moderately diverse subfamily of Braconidae with about 1,200 described species (Yu et al 2012) and many times that number are yet to be named
We treat a number of species from Thailand and propose 10 new genera
Most of these are demonstratively monophyletic and morphologically distinct; some compromises are made due to poor resolution in the phylogenetic analysis

Summary

Introduction

Agathidinae is a moderately diverse subfamily of Braconidae with about 1,200 described species (Yu et al 2012) and many times that number are yet to be named. Asperagathis Sharkey, new genus: This genus is sister to one of the Zosteragathis clades in the total evidence tree (Fig. 1). Cymagathis Sharkey, new genus: An autapomorphy for the genus is that the second median tergite is covered with strong smooth striae that end evenly at the apex of the tergite with the striae forming a semicircular pattern anteromedially.
