Abstract
There are no well defined
species groups based on the worker morphology from the Oriental region Arimoto (2017).
forms a complex species group with closely related species having little morphological changes Wilson (1958), Sarnat and Economo (2012). From the Oriental region, there are currently 9 species belonging to the
group. The group is diagnosed by having edentate masticatory margin of the mandible, smooth body surface, elongate antennae and metallic green cuticle. The species included are:
;

;
;

and
sp. n., a new ponerine ant species from Western Himalayas, India, is described and illustrated based on the worker caste. The new species belongs to the
group and mostly resembles
(Mayr, 1870). In the
group, the original description of
is insufficient as it lacks information about type material. As there is no further detailing of this species in the available literature, it is difficult to ascertain its valid status Xu and He (2015) and is therefore, considered a
herewith. A revised key to the known species of
-group in the Oriental Region is provided.
