Tapaya orbicularis longicaudatus Dugès, 1888 b

Dugès’ original description (Dugès 1888b) apparently was based on a single specimen. Smith & Necker (1943) reported that they found the type and gave a detailed description and measurements. In the series of Phrynosoma orbicularis specimens in the MADUG, one bears the locality “ Mexico ” and is labeled as Tapaya orbicularis and it broadly coincides with Smith & Necker’s (1943) description and measurements (HE 422, Fig. 6A). This specimen should be considered the holotype.

Current valid name: Phrynosoma o. orbiculare (Linnaeus, 1758).
