Hydrophylax leptoglossa

Hydrophylax leptoglossa (Cope, 1868)

Material examined. BANGLADESH • 1 adult; Sylhet Division, MoulvibazarDistrict, KamalganjUpazila, LNP, pond near Lawachara Station; 24°19.58′N, 091°47.04′E; 14 Jun. 2014; 20:38; photo voucher ZRC (IMG) 1.137.

Identification. A brown (rarely green) frog with mottled black flanks and a thick dorsolateral fold which is the same color as the dorsum. It can be distinguished from the similar Sylvirana nigrovittata (Blyth, 1856) by a more distinct dorsolateral fold and the established species range (Hasan et al. 2011), and from Hylarana tytleri by being broader in head and body, darker in color, and lacking the white-gold coloration of the dorsolateral fold (Kabir et al. 2009). Calls were 0.8–1.4 seconds long with a pulse rate of 8–9 pulses/s with pulses which distinctly alternated in amplitude. Dominant frequency of the calls peaked at 2400–2800 Hz with a fundamental around 600–700 Hz.

Habitat. This species was most often associated with streams and puddles in dried stream beds within mature forest. It was also found in streams in tea plantation and degraded forest and in paddy fields.
