Copeoglossum margaritae is known from only 3 specimens.
|Diagnosis||Diagnosis. Copeoglossum margaritae sp. nov. is characterized by (1) maximum SVL in males, not available; (2) SVL of holotype female, 118.8 mm; SVL of unsexed paratype MHNLS 3401 (probably female), 121 mm; (3) snout width, 2.93% SVL; (4) head length, 17.1% SVL; (5) head width, 12.6% SVL; (6) ear length, 1.14% SVL; (7) toe-IV length, 9.06% SVL; (8) prefrontals, two (n = 3); (9) supraoculars, four (n = 3); (10) supraciliaries, six (n = 3); (11) frontoparietals, two (n = 3); (12) supralabial below the eye, six (n = 2) or seven (n = 1); (13) nuchal rows, one (n = 2); (14) dorsals, 53–55 (n = 3); (15) ventrals, 66 (n = 2); (16) dorsals + ventrals, 119–120 (n = 2); (17) midbody scale rows, 30–31 (n = 2); (18) finger-IV lamellae, 15–16 (n = 2); (19) toe-IV lamellae, 16–17 (n = 2); (20) finger-IV + toe-IV lamellae, 32–33 (n = 2); (21) supranasal contact, N (n = 3); (22) prefrontal contact, N (n = 3); (23) supraocular-1/frontal contact, N (n = 3); (24) parietal contact, N (n = 2); (25) pale middorsal stripe, N (n = 3); (26) dark dorsolateral stripe, N (n = 3); (27) dark lateral stripe, Y (n = 3); (28) pale lateral stripe, Y (n = 3); and (29) palms and soles, dark (n = 3); data based on holotype unless indicated (Tables 3–5).|
Within the Genus Copeoglossum, C. margaritae sp. nov. differs from all other species by having a higher number of ventral scales (66 versus 54–65 in other species), a larger body size (121 mm maximum SVL versus 100–113 mm maximum SVL), and chin spotting (absent in the other species). It differs from C. arajara (Rebouças- Spieker 1981), additionally, in having more finger-IV + toe-IV lamellae (32–33 versus 26), more supraciliaries (six versus 3–5), and dark palms and soles (pale in C. arajara). It differs from C. aurae sp. nov., additionally, by having a longer supraocular-2 scale (supraocular-2/supraocular-1 length ratio 0.75–0.88 in C. margaritae sp. nov. versus 0.38–0.69 C. aurae sp. nov.) (Fig. 27) and in having a shorter toe-IV (9.06% SVL versus 10.1–12.7% SVL). It differs from C. nigropunctatum, additionally, in having a narrower frontonasal scale (frontonasal width/length 1.20–1.26 (n = 3) versus 1.30–2.03 in C. nigropunctatum; Fig. 26), by lacking supranasal contact (in contact in 94% of C. nigropunctatum), and by having a high number (32–33) of finger-IV + toe-IV lamellae (versus 94% of C. nigropunctatum with fewer than 32 lamellae). It differs from C. redondae sp. nov., additionally, by having a longer supraocular-2 scale (supraocular-2/supraocular-1 length ratio 0.75–0.88 in C. margaritae sp. nov. versus 0.58 in C. redondae sp. nov.; Fig. 27), more finger-IV + toe-IV lamellae (32–33 versus 29), and a smaller ear (ear length 1.14% SVL versus 2.42% in C. redondae sp. nov.).
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
