Indirana duboisi (Boulenger, 1882)

New records. INDIA • Karnataka: Udupi: Manipal , Pra- gathi nagar, site code H (13.3142°N, 074.8014°E), obs. by MM and RS, 21 Mar. 2017, 9 individuals, MN 952996 and MN 952997 . Fig. 3O .

Identification. The SVL is about 42 mm. The frogs have a unique, rotund, and stout structure. The eyes and darkbrown tympanum are almost of the same size. The dorsum has longitudinal folds and granules. The color is drab, pale muddy brown ( Dahanukar et al. 2016; Gopalan et al. 2012; Dinesh et al. 2020). The frogs have a continuous, black canthal stripe that connects the nostril to the tympanum.

Habitat. Throughout our surveys we have seen this frog take refuge in the dry season, at one location, under an inch or two of leaf litter. It was mostly seen active in monsoons, and the males were heard calling on nights with heavy rain. The male frogs are seen sitting on wet rocks throughout the town, mostly around old houses and shops. These frogs were seen living in near human habitation. The call consists of a single note, a low pitched “quack” with an interval of 6–8 sec; it was often heard from areas well covered by the canopy and with a few exposed laterite rocks.

Distribution. This frog is endemic to the southern West- ern Ghats.
