    The Ants (Hymenoptera, Formicidae) of Sri Lanka: a taxonomic research summary and updated checklist
    (ZooKeys 967, 2020) Dias, R.K.S.; Guénard, B.; Akbar, S.A.; Economo, E.P.; Udayakantha, W.S.; Wachkoo, A.A.
    An updated checklist of the ants (Hymenoptera: Formicidae) of Sri Lanka is presented. These include representatives of eleven of the 17 known extant subfamilies with 341 valid ant species in 79 genera. Lioponera longitarsus Mayr, 1879 is reported as a new species country record for Sri Lanka. Notes about type localities, depositories, and relevant references to each species record are given. Accounts of the dubious and some undetermined species from Sri Lanka are also provided. 82 species (24%) are endemic whereas 18 species that are non-native to Sri Lanka are recorded. The list provides a synthesis of the regional taxonomical work carried out to date and will serve as a baseline for future studies on the ant fauna of this biodiversity hotspot.

    Tetraponera modesta, a new pseudomyrmecine ant record (Hymenoptera: Formicidae) for Sri Lanka
    (Ukrainska Entomofaunistyka 2020, 2020) Dias, R.K.S.; Udayakantha, W.S.; Thotagamuwa, A.; Akbar, S.A.
    Tetraponera modesta (F. Smith, 1860) is herewith recorded for the first time from Sri Lanka. With this addition number of known Sri Lankan species for the genus becomes five. The other four species are T. allaborans (Walker, 1859), T. nigra (Jerdon, 1851), T. nitida (Smith, 1860), and T. rufonigra (Jerdon, 1851). Among the known regional species, T. modesta is easily separable by smaller size, yellow to orange brown colouration of the head and mesosoma, and relatively slender petiole.
