Abstract:
Though about 120 taxa ofTrachelomonas and 13 taxa ofStrombomonas are recorded from the Indian region, only about 60 taxa have been described fully. These descriptions are scattered in different journals. The present account brings together 70 taxa ofTrachelomonas and 36 ofStrombomonas collected from north-east, central and south India during 1937–1976, with keys and figures for their identification. Of these, 3 species ofTrachelomonas, viz.Trachelomonas costatus, Trachelomonas assamensis andTrachelomonas joysagarensis and 5 species ofStrombomonas, viz.Strombomonas hexagonalis, Strombomonas madraspatensis, Strombomonas vaseformis, Strombomonas indica andStrombomonas tortuosa are considered new. Sixteen varieties and forms ofTrachelomonas and 7 varieties and forms ofStrombomonas are also considered new. Nine species and 12 varieties ofTrachelomonas and 11 species and 7 varieties ofStrombomonas are new records for the Indian region. A list of 87 taxa ofTrachelomonas and 7 ofStrombomonas, the major part of which are only just listed by various authors for the Indian region, are given at the end of each genus. Some ecological observations onTrachelomonas andStrombomonas are given. The majority ofTrachelomonas species occurred in ponds with a fairly high degree of organic matter and fairly high nitrates and phosphates and low alkalinity during the rainless months of December to May.Strombomonas spp. were usually more common in ponds with higher alkalinity.Strombomonas verrucosa var.conspersa andTrachelomonas volvocina tolerated a wide range of total alkalinity. Excessive heat and sunlight or continuous rains seemed to have an adverse effect on the latter organism.
