Spea multiplicata has no boss between the eyes, and the eyelids are wider than the space between them. The dorsal color is uniformly brown or dark gray with small dark spots or blotches and red-tipped tubercles scattered over the dorsum, and no dorsolateral stripes are present. A short wedge-shaped spade is present on each hind foot. The iris is slightly variegated and appears pale copper colored. Male vocal sacs appear as a dark, heavily pigmented area on the throat (Conant and Collins 1991).
The body of the tadpole is broadest just behind the eyes, tapering gradually towards the bottom of the tadpole and tapering sharply towards the top. It has a short snout, and a tail that is about 1 1/3 - 1 1/4 times the head-body length that has its greatest width near the midpoint. The dorsal fin originates posteriorly on the body. The eyes are close together and well up on the head, and the anus is medial, emerging in the base of the ventral fin. The spiracle is low on the left side, belove the lateral axis of the body (Stebbins 1962).
Similar species: S. multiplicata can be easily mistaken for Spea bombifrons. Newly metamorphosed toadlets which have been in preservative for long periods of time are difficult to distinguish. S. multiplicata lacks a frontal boss, unlike adult S. bombifrons, but these two species frequently hybridize making this characteristic unreliable at times (Simovich 1994). S. multiplicata can be distinguished from Scaphiopus couchii by coloration: brown or dark grey with red-tipped tubercles in S. multiplicata, vs. greenish-yellow dorsum with dark mottling in Scaphiopus couchii (Degenhardt et al. 1996).
