Faunal richness and checklist of sandflies (Diptera: Psychodidae) in India

Abstract

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.
