| Diagnosis | Diagnosis: A moderate-sized Chondrodactylus (SVL to 89.3 mm SVL; CAS 176273; Bauer et al., 1993) bearing prominent subdigital lamellae. Body robust, somewhat depressed; head large, triangular, very broad across adductor musculature and angle of jaws (approximately as broad as long), snout moderately elongate, rounded (Fig. 5C), canthus rostralis relatively prominent, interorbital region weakly concave. Crown of head wide, flat; parietal table rectangular. Chin and gular scales enlarged, juxtaposed, either rounded or polygonal, a row of 5 chin scales approximately twice the width of a paravertebral dorsal tubercle (Fig. 7C). Dorsal head scales large, flattened (chiefly in midline) weakly domed (laterally), never keeled, larger on loreal region than on crown, largest above ears and across occiput. Anterior margin of ear bearing 3–4 enlarged conical tubercles. No discrete rows of enlarged dorsal tubercles. Dorsal scales large, heterogeneous in size, flat, and juxtaposed, rounded to polygonal, in some cases forming a virtual pavement of juxtaposed scales; interstitial granules absent or rare in northern specimens. Dorsal scales rounded, slightly raised but flat-topped in southern populations, never bearing a keel or mucro; interstitial granules often present (Fig. 6C). Scales on thighs flattened to weakly conical, smooth, not keeled or mucronate. Tail weakly (Fig. 11C) to strongly (Fig. 11D) verticillate, each whorl at tail-base bearing six enlarged conical (dorsal) to mucronate (lateral) tubercles, less prominent than in congeners; tubercles per whorl decreasing distally (Heinz et al. 2021).
