The Lecane-species complex taxonomy the world over, witnessed a state of flux, causing confusion and controversies, among world taxonomists over the treatment of various subgenera, taxa and sub and or infraspecific categories of the species rich genus Lecane Nitzsch 1827, on the basis of structure/shape of key, morphological features like foot/toes, lorica, etc. The taxonomic scenario in India, relying heavily on the classical, divergent taxonomic approaches presented a picture of more chaos/confusion, following poor accessibility to contemporary revisionary studies until the recent past. Despite revisionary studies across the world, a few notable Indian studies continued to be burdened with old nomenclature. This short communication reports for the first time ever, 33 valid species of lecanid rotifers (Lecanidae), including six new distributional records from Greater Hyderabad region and the entire state of Andhra Pradesh too with comments on their current nomenclature. Further, limnobiological correlation between five physicochemical parameters and rotifer associations revealed, L. bulla, L. closterocerca, L. hamata, L. ludwigi, L. luna and L. papuana as euryokous species, showing tolerance to a wide range of abiotic factors and habitats too.
