In the local Angami language, a major tribal language in Nagaland, “Dzu” means water and “leke” means underground. Thus, the name Dzuleke reflects the unique hydrological feature of the stream in this region as it flows underground at one point in its course.</p><p>Distribution: Nagaland, India (Fig. 13).</p><p>Diagnosis: Baetis (T.) dzulekensis Vasanth, Kubendran, Subramanian &amp; Gattolliat sp. nov. can be distinguished from all known species of the subgenus Tenuibaetis by the following combination of characters: (i) labrum rounded, dorsal submarginal arc of setae composed with 1+5 simple setae (Fig. 2A); (ii) right mandible: canine with 3+4 denticles (Fig. 2C); (iii) maxillary palp much longer than galea-lacinia; (Figs 2E–F); (iv) paraglossae with 3–4 long setae on dorsal surface, labial palp segment II slightly produced apicolaterally (Fig. 3A); (v) dorsal margin of forefemora with 24–25 long, stout, spatulate 2-channel setae (Fig. 3B); (vi) dorsal surface of all tibia with stout, apically rounded setae (Figs 3J, 4B); (vii) claw with a row of 12–13 denticles (Figs 3E, 4C); (viii) posterior half of mesonotum without any distinct marking (Figs 1A–C); (ix) tracheation of gills transparent (Figs 4D–E).</p><p>Ecology: The riverbed composition is as follows: Gravel 5%, Cobbles 30%, Boulders 35%, Bed rock 5%, Fine sand 15% and Slit 5%. In summer, the Dzulerudi River is 3–3.5 m wide and 22–25 cm depth and medium water current (0.6 m /sec.), temperature (atmosphere) 21°C, temperature (water) 18.1°C, humidity 40% and pH 6.6.
