| Types | Syntypes: MNHN 6201, MNHN 1994.1356 |
| Diagnosis | DIAGNOSIS: Leptodeira ornata can be distinguished from their South American congeners by the following combination of characters: (1) dorsal scales 17–21/19–23/13–17; (2) presubocular present; (3) supralabial scales 8–9/7–9, (4) infralabial scales 9–11/9–11; (5) ventral counts in males 170–193 and fe- males 169–194; (6) subcaudal counts in male 81–105 and females 77–99; (7) dorsum of the head brown, generally without spots; (8) occipital region light brown with medial wide line; (9) number of dark brown dorsal blotches in males 29–55 and females 29–56; (10) number of dorsal blotches in tail in male 18–36 and females 14–28; (11) SVL in males 341–543 mm and females 343–646 mm; and (12) tail long in males 27.77% of TTL and females 24.49% of TTL. Leptodeira ornata differs from L. annulata and L. approximans by the presence of medial wide line (vs. without well-defined occipital dark stains); from L. ashmeadii, L. bakeri, L. larcorum, L. pulchriceps, and L. tarairiu sp. nov. by the presence of a dark butterfly-shaped spot (vs. dark horseshoe-shaped spot in L. ashmeadii, L. pulchriceps, and L. tarairiu sp. nov.; a dark bar-shaped in L. bakeri; and dark butterfly-shaped spot in L. larcorum). (Costa et al. 2022: Supplement S2). VARIATION: Preocular counts 1 (N= 109) / 1 (N= 108) or 2 (N= 1). Postoculars counts 1 (N= 1), 2 (N=103)or3(N=5)/2(N=106)or3(N=2). Supralabialcounts8(N=105)or9(N=4)/7(N=1), 8 (N= 105) or 9 (N= 3). Number of supralabial scales contacting eye 3–5 (N= 4), 4–5 (N= 102) or 5–6 (N= 3) / 3–4 (N= 1), 3–5 (N= 2), 4–5 (N= 103) or 5–6 (N= 3). Infralabial counts 9 (N= 3), 10 (N= 66) or 11 (N= 39) / 9 (N= 2), 10 (N=68) or 11 (N= 37). Number of infralabials contacting anterior chinshields 1–4 (N= 1), 1–5 (N= 69) or 1–6 (N= 39) / 1–5 (N= 72), or 1–6 (N= 37). Dorsal counts at the first third of the body in males 17 (N= 3), 19 (N= 51) or 21 (N= 1) and females 17 (N= 1), 19 (N= 33) or 21 (N= 20); dorsal counts in the middle of the body in males 19 (N= 15) or 21 (N= 40) and females 19 (N= 4), 21 (N= 45) or 23 (N= 5); and dorsal counts at the last third of the body in males 13 (N= 6), 15 (N= 48) or 17 (N=1) and females 15 (N= 32), or 17 (N=22). Ventral counts in males 170–193 (mean= 183.67; SD= 5.39; N= 40) and females 169–194 (mean= 183.68; SD= 5.06; N= 54). Subcaudals counts in males 81–105 (mean=94.68; SD= 4.97; N= 41) and females 77–99 (mean= 85.97; SD= 4.79; N= 39). Largest male SVL 543 mm and female 646 mm. Head length in males 15.37–21.76 mm (mean= 18.42; SD= 1.52; N= 54) and females 15.00–27.25 mm (mean= 21.83; SD= 2.51; N= 52). Head width in males 8.60–13.31 mm (mean= 10.62; SD= 1.03; N= 52) and females 9.06–18.02 mm (mean= 13.05; SD= 1.95; N= 50). TL in males 134–212 mm (mean= 172.6; SD= 20.69; N= 40) and females 111–203 mm (mean= 164; SD= 18.60; N= 38). (Costa et al. 2022: Supplement S2). |
| Comment | Synonymy: Mostly after Costa et al. 2022. L. s. ornata has been considered as invalid (D. Mulcahy, pers. comm. 3 March 2013, polyphyletic in Daza et al. 2009), but revalidated by Barrios-Amoros 2019. Note that Torres-Carvajal et al. 2020 redefined and restricted L. ornata to a single monophyletic clade in Panama, Colombia and Ecuador. Similar species: L. septentrionalis, L. larcorum Habitat: partly arboreal (Harrington et al. 2018). Distribution: see map in Costa et al. 2022: Fig. 12 in Supplement S2. The status of populations in Panama and Ecuador seems to be unresolved (see Costa et al. 2022). |
