Material examined. BANGLADESH • 1 adult; Sylhet Division, Moulvibazar District, Kamalganj Upazila, LNP, stream near Lawachara Station ; 24°19.56′N, 091°47.15′E; 16 Jun. 2014; 20:38; photo voucher ZRC ( IMG) 1.124 GoogleMaps .

Identification. This frog was verified as C. alticola due to yellow to brown coloration with a long, pointed head and slender legs ( Kabir et al. 2009) and by calls including a variety of squeaks and trills. Typical squeak was 45–70 ms with a dominant frequency that started from 2000–3000 Hz and dropped to under 1000 Hz along with another frequency band that started at 3500 Hz and dropped to near 1000 Hz. A different call lasted 300 ms with frequency bands that started at 1200 Hz and 1800 Hz and then rose to 1600 Hz and 2300 Hz. There was also a low-frequency trill which lasted about 230–500 ms, composed of 5–18 pulses of only 10–20 ms each, each pulse starting at about 2500–3000 Hz and dropping to 1000–2000 Hz. Other trills of similar length had 30 ms pulses with a consistent 2300 Hz frequency.

Habitat. Clinotarsus alticola was found calling on streambanks throughout mature forest and on occasion in degraded forest. Otherwise it was found sitting at the edge of forest trails.
