An updated checklist of Nepalese ants (Hymenoptera, Formicidae)

The location of Nepal in the Central Himalaya promotes high habitat and species diversity. Ant diversity is likely high, but there have been few studies of the diversity and distribution of ants in Nepal. Here we present an updated checklist list of Nepalese ants that includes 128 named species in 48 genera and eight subfamilies. Among these species, 21 species have a type locality from Nepal, nine species are endemic to Nepal, and three are introduced species. We add six new ant records for Nepal, namely Harpegnathos venator, Monomorium pharaonis, Nylanderia bourbonica, Odontoponera denticulata, Polyrhachis tyrannica and Pseudoneoponera bispinosa. The checklist presents distribution records for Nepalese ant species and provides comparisons with the neighboring countries of China and India.
