Introduction to Ants of Sri Lanka

 

Ants are a very common group of insects (Order: Hymenoptera, Family: Formicidae) in almost all terrestrial habitats such as forests, cultivated (highly disturbed) lands, bare-lands, human habitations and uncultivated lands in Sri Lanka. They can mainly be ground-living (in soil, leaf litter and decaying wood pieces etc.) or arboreal and are temporary or permanent nest builders in the microhabitat. Ward (2007) revised the valid tribe names of Family Formicidae. Worker ants belonging to 12 subfamilies, Aenictinae, Aneuretinae, Cerapachyinae, Dolichoderinae, Dorylinae, Ectatomminae, Formicinae, Myrmicinae, Ponerinae and Pseudomyrmecinae, were reported earlier from Sri Lanka but due to the taxonomic revision of Brady et al. (2014), which subsumed the six previous dorylomorph subfamilies into a single subfamily, Dorylinae, two subfamilies, Aenictinae and Cerapachyinae, are currently invalid; the members of those two subfamilies are currently included in Dorylinae; hence, total number of subfamilies recorded from Sri Lanka becomes 10. The 63 genera rose to 66 recently and total number of known species and morphospecies is 230 (Dias, 2014). According to the recent generic level taxonomic revision of Ponerinae (Smith and Shattuck, 2014) of the world, Pachycondyla recorded from Sri Lanka becomes an invalid genus name. Also, Mesoponera (many specimens of Pachycondyla are now placed in this genus) and Pseudoneoponera (formerly known as Pachycondyla rufipes) should be added to the existing list of genera recorded from Sri Lanka. The myrmicine genus, Pheidologeton, is now placed under the genus Carebara. The myrmicine species, Monomorium destructor, is revised as Trichomyrmex destructor, recently. A subgenus of Camponotus (Family Formicinae) has been resurrected to genus level also (Ward et al., 2016).

The website on ants of Sri Lanka summarizes the findings of extensive field surveys conducted in Gampaha, Colombo and Galle Districts (2000-2003), extensive and intensive surveys in Ratnapura District (2000-2006), Anuradhapura (2006-2008), Polonnaruwa, Puttalam and Kurunegala Districts (2009). Aneuretus simoni Emery was discovered in several forests in Sri Lanka recently, outside the previously recorded localities, and will be added to the website soon.
