Rare Monotypic Genus Leptosiropsis Jao from Supaul District of North Bihar, India

During present investigation authors collected the monotypic genus Leptosiropsis Jao from two different sites of Supaul district of North Bihar. Earlier the genus was also reported from Bihar by [5-6]. It was also reported by [5], [7] from West Bengal. Hence it is evident that it occurs frequently in some parts of eastern Bihar. Apart from Bihar it was reported from Lucknow by [2-3]. Hence distribution pattern of the genus Leptosiropsis Jao reflects its very restricted occurrence. A critical study is needed to ascertain that whether it is due to ecological factors or our poor state of exploration. Lack of plasticity in morphological characters is another point to pay attention because all specimens reported from different localities so far show very little variation in dimension or other characters. Hence a further intense study is needed to understand the nature and systematic position of this rare taxon. During the taxonomic investigations of freshwater filamentous green algae of Supaul district of North Bihar, the authors recorded a good number of Chaetophoralean algae. In this communication a rare monotypic genus Leptosiropsis (type species: L. torulosa Jao) is described and illustrated.
