TypesHolotype. UTA R-60249 (Figs. 1, 2), an adult male, (Fig. 4); collected on 17 August 1979 by William W. Lamar and Eduardo Thierry. 
CommentCercosaura 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.

Diagnosis. (1) supraoculars three; (2) superciliaries 4–5, first expanded onto dorsal surface of head; (3) palpebral eye-disc made up of a single, undivided scale; (4) supralabials five; (5) infralabials five; (6) dorsal body scales hexagonal, with high rounded keel; (7) dorsal scales in transverse and oblique rows; (8) transverse rows of dorsals 28–31; (9) a continuous series of small lateral scales separating dorsals from ventrals, 4–7 scales wide; (10) transverse ventral rows 16–20; (11) longitudinal ventral rows six; (12) femoral pores per hind limb 8–12; (13) preanal pores absent; (14) subdigital lamellae on Toe IV 18–22; (15) limbs overlapping when adpressed against body; (16) dorsolateral stripe passing through dorsal surface of the eye and lateral stripe beginning on the supralabials, no vertebral stripe.
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.
