W. brachyura is found in isolated localities in the state of Maharashtra in western peninsular India.

[3] The following description is based on Malcolm Smith (1943): Nostril large, between two nasals; internasals 0.3 to 0.5 as long as the prefrontals; frontal nearly as broad as long, in contact with a large preocular; loreal longer than high; 2 postoculars; temporals 2+2; 8 supralabials, 4th and 5th touching the eye; anterior genials larger than the posterior, the latter separated by two or three series of small scales.

Scales in 23:23:19 rows; ventrals large, rounded; tail rather short.

The distal half is calyculate, the cups being large and with scalloped edges; the proximal half is spinose, two or three spines at the base being much larger than the others (bad specimen).

Olive-brown above, with indistinct light variegations on the anterior half of the body and head; lower parts whitish.
