. Eight new species of Psalitrus are described: P.besucheti, P.coccinelloides, P.decoratus and P.silvestris from Southern India and P.loebli, P.mahanuwara, P.serendibensis and P.veddha from Sri Lanka. The two Psalitrus known previously from India, P.championi and P.fallax , are redescribed and lectotypes and paralectotypes are designated. For each species the aedeagus and female ectodermal genitalia are figured. For the first time among Hydrophiloidea species characters have been found in female ectodermal genitalia, thanks to staining with chlorazol black dye. The best biometric characters are selected by multiple‐discriminant analysis and an identification key is given. A list of the known Psalitrus species is given.
