We did not collect or measure morphological data from these individuals. Male individuals from type locality are smaller (37.0– 40.2 mm, n=3) than female individuals (42.4–47.4 mm, n=2) exhibiting sexual dimorphism. Males have femoral glands, while females do not have them. In all the external morphological features they are similar to holotype. In all the specimens of Nyctibatrachus tunga sp. nov. fourth toe disc with dorso-terminal groove, cover bifurcate distally and webbing medium, reaching third subarticular tubercle on either side of toe IV (I 0 – ½ II 0 – 2 III 0 – 3 IV 3 – 0 V).

The specific epithet is derived from the name ‘Tunga’. The species is recorded in the catchment areas of the river Tunga and the species epithet is a noun in apposition to the generic name.</p> <p>Suggested common name. Tunga River Night Frog.</p> <p>Distribution and Natural History. Nyctibatrachus tunga sp. nov. is observed from the upper catchment area of River Tunga as shown in Figure 1. Adults and tadpoles were observed from streams at Nemmar village, Sringeri Taluk, Chikkamagaluru District, Karnataka State, India (13.34325°N, 75.25337°E, 700m amsl). They were identified using molecular analysis of skin swabs and tadpole tail tips and are used in the phylogenetic tree. Uncorrected p values between the individuals of type locality and this locality is in the range of 0.22 to 0.44, confirming the identity of Nyctibatrachus tunga sp. nov. We did not collect these individuals. There is a possibility that it is more widespread and occurs beyond its currently known localities. Based on our field observations, this species is locally abundant in the surroundings of the type locality and is restricted to perennial streams of the coffee estates, evergreen, and semi-evergreen forests. Canopy cover of the streams ranged between 80-90%, with stream width ranging from 47–50 cm and stream depth ranging from 3.0– 4.4 cm. Water temperature ranged between 21.5–22.1°C. The air temperature was 25.9±0.3 °C, relative humidity was 66.2±0.07%. Streams had small gravels, sand, and leaf litter with intermittent big boulders. Water in the stream was slow flowing.</p> </div>	https://treatment.plazi.org/id/03B9D305FFB2FFE2FF1164C7FB94FB96	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
