Jeet Sukumaran’s Torrent-Dwelling Toad
Species Description: Wood Jr PL, Grismer LL, Ahmad N, Senawi J 2008 Two new species of torrent-dwelling toads Ansonia Stoliczka, 1870 (Anura: Bufonidae) from peninsular Malaysia. Herptologica 64:321-340.
Ansonia jeetsukumarani is most visibly similar to A. malayana, but can be distinguished by its lack of a large yellow wart at the angle of the jaw and of a white patch below the eye, which are both present in A. malayana. They also differ in the color of the iris, which is reddish brown in A. jeetsukmarani and golden in A. malayana (Wood et al. 2008).
In live individuals the dorsum is brown except for an orangish-yellow spot between the scapulae and a thin, faint vertebral stripe. The limbs are orangish with light crossbars. The hands and feet have brown and orange bars. The iris is reddish brown with black reticulation. The ventral surface is dark. Whitish spots are present on the ventral side from the gular region to the hind limbs. The ventral side of the hind limbs is brownish-red in females and brown in males. In preserved specimens the dorsum is black and the lateral surfaces are faintly yellowish-orange. The limbs are black with yellowish-orange crossbars. The vental surface is cream to brown with dark blotches, and lighter spots remain present in the gular region (Wood et al. 2008).

The genus Ansonia is composed of two distinct and well-supported clades. Ansonia jeetsukumarani is a member of a clade containing 17 species from Peninsular Malaysia, Thailand, and Borneo (Matsui et al. 2010).
Ansonia jeetsukumarani is named in honor of contributions made by Jeet Sukumaran to the understanding of biology of Malaysian amphibians (Wood et al. 2008).
