The worker caste of the ant species Protanilla schoedli is discovered and described for the first time based on specimens collected across Sri Lanka. The specimens examined demonstrate within-species morphological variations in body size, petiolar shape and colour. A distributional map and worker images to facilitate its identification are provided.
There are no well defined Leptogenys species groups based on the worker morphology from the Oriental region Arimoto (2017). Leptogenys chinensis 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 L. chinensis 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: L. assamensis; L. chinensis; L. confucii; L. kraepelini; L. laeviterga; L. pangui; L. peuqueti; L. stenocheilos and L. sunzii.Leptogenys bhartii 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 Leptogenys chinensis group and mostly resembles Leptogenys chinensis (Mayr, 1870). In the L. chinensis group, the original description of L. stenocheilos 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 species inquirenda herewith. A revised key to the known species of chinensis-group in the Oriental Region is provided.
Temnothorax elmenshawyisp. n., a new ant species from the Asir Mountains of the southwestern region of the Kingdom of Saudi Arabia, is described based on the worker caste. The new species is a member of theT. exilisspecies group and is distinguished from the other species included in this group by the impressed metanotal groove, the short, acute and broadly-based propodeal spines, the finely punctate posterior half of cephalic surface, and absence of a median clypeal carina. Despite extensive collecting by the authors at the type locality, only two specimens are available for description, suggesting that this species may be rare and likely endemic to the Asir Mountains. The species description is complemented by still images of volume renderings of a 3D model and a 3D rotation video of the holotype based on x-ray microtomography (micro-CT), allowing remote in-depth examination of the specimen. The virtual micro-CT data is provided as cybertype dataset and freely available onlinehttps://doi.org/10.5061/dryad.4gg39k6, as well as 3D surface model (Sketchfab.com, https://skfb.ly/6HYRz). An updated identification key to the Arabian species is presented.

The Indian soldierfly fauna is rich and diverse, yet it is poorly studied as most species were described in the 19th century. Soldierflies, like most other organisms, especially in developing nations such as India, have been largely overlooked in recent times. In this study, we present an inventory of all names so far validly published in Indian Stratiomyidae. Synonyms, notes about type localities, depositories, and distribution are included. The study revealed that the soldierfly species list from India comprises 84 valid species, distributed in 35 genera and 7 subfamilies. The present study provides a synopsis of the regional taxonomical work carried out until now, and can serve as a baseline survey for future studies. The study indicates that most areas of the vast Indian territory are unexplored for soldierflies, and perhaps the majority of the soldierflies in India still remain discovered
