To report a new species of sandfly, Sergentomyia (Neophlebotomus) ashwanii sp. nov. (Diptera: Psychodidae) from Western Ghats, India. A systematic sandfly survey was conducted in the Thrissur and Kollam districts of Kerala, India using mechanical aspirators, light and sticky traps, both indoor and outdoor habitats, for a period of one year. Deoxyribonucleic acid barcoding of samples was performed targeting mitochondrial cytochrome oxidase I (COI) gene and sequence generated was subjected to phylogenetic analysis. Sergentomyia (Neophlebotomus) ashwanii, a new sandfly species is recorded and described in this communication. A single row of 10-12 pointed teeth in the cibarium with 4-6 small denticles or fore-teeth are the key characteristics that is distinctive from other members of the subgenus Neophlebotomus. Mitochondrial COI barcode followed by phylogenetic analysis of the nucleotide sequence confirms that specimens of the species belong to the same taxonomic group while the genetic distance (14.2%) with the congeners established it to be a different species. The Western Ghats' being an important biodiversity hotspot and has dearth of systematic entomological surveys on sandflies. The current study tried to fill the void and also report a new sandfly species.

This review aims to fill the voids and to update the checklist of sandfly fauna along with its spatial distribution in India. Resource databases i.e. either online or offline were searched to deduce the information to systematize the Indian sandfly fauna. Articles/data retrieved were screened and analysed to further update the available latest checklist. The species name and authorship were given in accord with the International Code for Zoological Nomenclature. We compiled an updated checklist of reported Indian sandfly species along with their state-wise distribution till 2022 as per published literature. Kerala has maximum number of species reports when compared to other endemic states and states with pockets of transmission. Phlebotomus argentipes is the most widely distributed, recorded so far, followed by other Sergentomiya and Phlebotomus species in India. In this review, we have also described the vector and non-vector species of sandfly prevalent in different parts of the country. Phlebotoiella eoindianensis, an amber fossil sandfly species recorded from Gujarat might be older than other records of Indian sandfly fauna. So far 69 species (4 genera and 15 subgenera/groups) of Phlebotomine sandflies have been recorded in India. Proper knowledge of species diversity and its distribution is a prerequisite for planning a systematic vector control strategy and disease management.
