M.repentina Distant, 1904, M. singalensis Kirkaldy,1903,M. albomaculata Distant,1909, M.kumaonensis Distant,1909, M.diluta Distant 1909 and M. annandelei Distant, 1909. One new species of the genus Microvelia(s.str.)distanti sp.nov. is described from Haridwar, India

                  The Vellidae are best known of all aquatic hemiptera of the world and are extremely common in Indian waters. The members of the family are easily differentiated from the related family Gerridae based on hind leg not surpassing beyond the tip of abdomen and the presence of median longitudinal groove on vertex.Microvelia Westwood,1834 belongs to the subfamily Microveliinae China & Usinger, 1949 of the family Veliidae.
