Abstract

We morphologically describe three new species of the subgenus Tenuibaetis Kang & Yang, 1994 based on larvae recently collected from streams and rivers in different states of North India. Baetis (Tenuibaetis) dzulekensis sp. nov. is characterized by labrum rounded, dorsal submarginal arc of setae composed with 1+5 simple setae; dorsal margin of forefemora with 24–25 long, stout, spatulate 2-channel setae. Baetis (Tenuibaetis) jhargramensis sp. nov. is characterized by submarginal arc of labrum with 1+6 simple setae; dorsal margin of forefemur with 20–21 long, stout, apically rounded 2-channel setae. B. (T.) reasiensis sp. nov. is characterized by labrum with dorsal submarginal arc of 1+7 simple setae; dorsal margin of forefemur with row of 22–23 long, stout, apically rounded 2-channel setae; claw with a row of 12 denticles. Additionally, we provide ecological notes on the streams and rivers where these species were collected. A comparison of the morphological characters of all known species of Tenuibaetis from India is also provided.
