Abstract

The amblyoponine genus Opamyrma is newly established for a single new species, O. hungvuong, found from central Vietnam. The genus is morphologically very close to the genus Apomyrma known from the Afrotropical region, but is well distinguished from the latter by a combination of the following features in the worker of the former: preoccipital carina complete, almost encircling the head slightly before its posterior margin; clypeus posteriorly margined with a distinct continuous carina; petiole without a distinct anterior peduncle; abdominal segment III longer than IV, V and VI; segment VII longest among the segments III-VII; anteriormost part of abdominal sternite III produced anteriad to the same level as the anteriormost part of the tergite III; abdominal segment IV with differentiated presternite. The new genus is tentatively assigned to the subfamily Amblyoponinae.
