Cercosaura hypnoides is most similar to the species that were formerly considered to belong to the genus Pantodactylus (Ruibal, 1952), but may be distinguished from each of them by having lateral scales that are much smaller than the dorsal scales (versus dorsals and laterals approximately equal in size in C. parkeri (Ruibal), C. quadrilineata Boettger, C. schreibersii Wiegmann, and C. steyeri). Cercosaura hypnoides may also be distinguished from C. quadrilineata by having six longitudinal rows of ventral scales (versus 4). Cercosaura hypnoides can be further distinguished from C. parkeri (Ruibal) by the high femoral pore count of 8–12 (versus 2–6 for C. parkeri). The new species can be distinguished from C. schreibersii Wiegmann by having three postocular scales (versus two) and by having 8–12 femoral pores versus 3–5. Cercosaura hypnoides can be distinguished from C. steyeri by having six longitudinal rows of ventral scales (versus 4 in C. steyeri).
The new species can be distinguished from additional species of the genus Cercosaura by possessing hexagonal dorsal scales arranged in transverse and oblique series (versus quadrangular dorsals in transverse and longitudinal series for C. ocellata Wagler and by having only transverse series in C. argulus Peters, C. dicra (Uzzell), C. eigenmanni (Griffin), C. manicata O’Shaughnessy, C. nigroventris (Gorzula and Señaris), C. phelpsorum (Lancini), and C. vertebralis O’Shaughnessy). The new species can be further separated from C. dicra and C. vertebralis by having three supraocular scales (versus four). Cercosaura hypnoides can be distinguished from C. dicra (8), C. manicata (8), and C. nigroventris (8) by having six longitudinal rows of ventral scales. The new species additionally differs from C. argulus, C. eigenmanni, C. ocellata, C. phelpsorum and C. vertebralis in its pattern of dorsolateral and lateral stripes.
|Comment||Cercosaura hypnoides differs from all other species of Cercosaura by possessing three supraoculars, a single palpebral scale, five supralabials and infralabials, hexagonal, keeled dorsal scales arranged in transverse and oblique rows, small lateral scales, six longitudinal rows of ventrals, 8–12 femoral pores per hindlimb, 18–22 subdigital lamellae on the fourth toe, overlapping limbs when adpressed against the body, and the pattern of two dorsolateral and two lateral stripes throughout the head, body, and tail.|
Abundance: only known from its original description (Meiri et al. 2017).
|Etymology||The specific epithet is taken from the New Latin adjective hypnum, in turn derived from Greek hupnon (a type of lichen, + -oid) meaning “of the moss in reference to the luxuriant moss growth that characterized the lizard’s habitat and egg deposition sites.|
