An strated account of six species and ten varieties of the genusLepocinclis Perty and thirty-nine species and ten varieties of the genusPhacus Duj from inland waters of northeast, central and south India collected during 1937–76 together with their distribution in the Indian region is given. Of these, three varieties ofLepocinclis (L. lefevrei varcuttackensis, L. elongata varminor andL. playfairiana varminor) and one species ofPhacus (P. mammillatus) and four varieties (P. balatonicus varmajor, P. acuminatus varbarrackporensis, P. caudatus varmajor andP. ranula varbrevicaudatus) are considered new. Two species and two varieties ofLepocinclis (L. spirogyra Korsh,L. steinii Lemm,L. steinii varsuecica Lemm. andL. ovum varverrucosum Prowse) and twelve species ofPhacus (P. lefevrei Bourr,P. nannos Pochm,P. wettsteinii Drez,P. textus Pochm,P. carinatus Pochm,P. formosus Pochm,P. obolus Pochm,P. ranula Pochm,P. sesquitortus Pochm,P. atrakoides Pochm,P. glaber (Defl) Pochm. andP. hispidula (Eichw) Lemm. and one variety (P. ranula varafricana Bourr) appear to be new records for the Indian region. Although 13 taxa ofLepocinclis (5 species and 8 varieties) and 79 taxa ofPhacus (61 species and 18 varieties) have been reported previously from the region there are only a few reports which give full details. Some of the records also appear to be doubtful. Keys to the taxa of the two genera described and lists of other taxa of the genera reported from the region are also given. Latin diagnosis ofEuglena tuba Carternon Johnson emend. Philipose 1982 is given to validate the species. Three additional species,viz E. orientalis Walton,E. elastica Prescott andE. clara Skuja are also described, the last being a new record for India.
