    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.

    New Records of Ants (Hymenoptera: Formicidae) from Sri Lanka, Including Four Tramp Species
    (Sociobiology, 2018) Dias, R.K.S.; Udayakantha, W.S.; Wachkoo, A.A.; Akbar, S.S.
    Five ant species are reported for the first time from Sri Lanka: Ooceraea alii (Bharti & Akbar, 2013); O. biroi (Forel, 1907); Prionopelta kraepelini Forel, 1905; Strumigenys emmae (Emery, 1890) and S. membranifera Emery, 1869. Among the newly reported species, four species (O. biroi, S. membranifera, S. emmae and P. kraepelini) are known for their invasive and tramping nature, spreading via human commerce and have attained broad cosmopolitan distribution. Impact of these ants on regional fauna is not known and needs immediate attention. A brief diagnosis, distribution, and illustrations are provided for each species.
