Body ovoid in dorsal view, wider than high (Fig. 1AB); body height 45% of body length and 67% of body width. Eyes dorsolateral with diameter 14% of body length; distance between eyes 27% of body width. Nostrils ovoid, half-way between the snout and eyes; distance from snout to nostrils 12% of body length; nostril diameter 50% of the snout to nostril distance.
