First Record of Anisops tahitiensis Lundblad (Hemiptera: Nepomorpha: Notonectidae) from Mainland India

The Notonectidae is one of the largest families of the Nepomorpha with eleven genera and 400 described species (Henry, 2009), represented well in both temperate and tropical areas of the World (Nieser, 2004). The genus Anisops Spinola, 1837 is characterized by hair-lined pit on the hemelytral commissure, one segmented fore tarsi on both the sexes and the presence of rostral prong as well as stridulatory comb on fore tibia of males. They are adapted to swim with their back, thus bearing the common name back swimmers and some species are generally attracted to light. Thirumalai (2007) recorded 19 species of Anisops from India, subsequently Jehamalar and Chandra (2013) added one more species to the Indian fauna by recording Anisops occipitalis from Great Nicobar Island.
