Remarkable range extension of the genus Nordeniella Lelej, 2005 (Hymenoptera: Mutillidae: Smicromyrmini): Description of a new species from Sumbawa, Indonesia

Abstract

The genus Nordeniella Lelej, 2005 had been known from India and Sri Lanka. Recently, this genus was discovered from Southern Thailand in 2019. A new species N. sumbawaensis Okayasu sp. nov. (♀) is described from Sumbawa, extending the geographical range of Nordeniella beyond Wallace Line. This new species is most similar to the Thai species N. maleeae Williams in Williams et al., 2019, but can be separated based on morphology. The occurrence of Nordeniella in an Indonesian island suggests wider distribution of this genus in the eastern Oriental Region.
