Redescription of three antlions (Neuroptera: Myrmeleontidae) from Kerala part of the Western Ghats and key to antlion genera in tribe Palparini, India

Indopalpares pardus (Rambur, 1842), Palpares contrarius (Walker, 1853), and Stenares harpyia (Gerstaecker, 1863) are the species of the tribe Palparini which are recorded for the first time from the Kerala part of Western Ghats. All three taxa are redescribed and the genitalia features of P. contrarius, and S. harpyia are illustrated for the first time based on the freshly collected specimens. Lectotype and paralectotype specimens of S. harpyia are designated. The key to the genera of the tribe Palparini from India and the distribution of three species in India are also mapped. Moreover, their flight period in India is plotted.
