Named after the French priest and naturalist Hermano Nicéforo María (born Antoine Rouhaire Siazaude), who established important natural-history collections at the Instituto de la Salle in Bogotá. While numerous taxa have been named mariarum, nicefori, or some derivative (see Adler 1989), he requested in a 1968 letter that he be addressed in print using his full name, Hermano Nicéforo María ( Rodriguez 2002). Thus , it seems appropriate to use the specific epithet niceforomariae .

Diagnosis. Synophis niceforomariae can be differentiated from all other similar or related species by the combination of an unmodified vertebral scale row with a single weak keel; smooth nuchal scales; absence of a nuchal collar in adults; presence of a loreal; intranasals in contact; fused prefrontals; rostral concave; anal single; no apical pits; 2 postoculars; 10–12 infralabials; 8 supralabials; 184–193 ventrals; 127–131 subcaudals; and 19-19- 17 dorsal scale-rows.

Description. Small-sized, long-tailed snakes (~ 400mm SVL, 200mm TL) with slender bodies and head distinct from neck. Eye large (>1/3 head height), bulbous, and black in life, with pupil not easily distinguishable from iris. Pupil round in preservative (though this may be an effect of fixation). Dorsum coloration grayish-brown with iridescent sheen in life and preservation, no light-colored nuchal collar in adults, and posterior supralabials mostly unpigmented (<50%). Ventral coloration primarily bright yellow, extending onto margins of ventral scales and supralabials. Anterior one-third of ventral surface yellow; posterior two-thirds to vent becomes increasingly mottled, and ventral surface of tail same color as dorsum.

Remarks. This species was referred to as Synophis cf. bicolor by Pyron et al. (2015). The cleared-and-stained skull of the male holotype was prepared by Martinez (2011), with illustrations of the cranium and mandible (her Figs. 15, 18, & 22), but the hemipenis was not illustrated or described in detail. Condition of the vertebrae, which are heavily modified in Emmochliophis and some Synophis ( Fritts & Smith 1969; Savitzky 1974; Hillis 1990) unknown, pending skeletal preparation, micro-CT scanning, or X-rays. Has a very small known range to the east of Yarumal, Colombia, at ~ 1300–1600m around Campamento, Anori, and Amalfi. Two reportedly similar specimens in the Instituto de Ciencias Naturales de la Universidad Nacional de Colombia (ICN) were collected slightly to the south of the populations sampled here, at lower elevations (~ 900–1300m; Table 2 ). We did not examine these individuals, but it seems likely that they are also S. niceforomariae , and that the range of the species is slightly larger ( Fig. 4 ).

With this new species and the re-assignment of numerous specimens examined by Pyron et al. (2015) and Torres-Carvajal et al. (2015), the known species limits of many Synophis taxa have changed. In particular, Pyron et al. (2015) assigned specimens of S. bogerti , S. calamitus , and S. niceforomariae to S. bicolor and assigned specimens of S. zamora to S. bicolor and S. lasallei . Similarly, Torres-Carvajal assigned specimens of S. niceforomariae to S. bicolor . Using the updated information from the combined datasets ( Tables 1 , 2 ), we provide a checklist with updated summaries of geographic, elevational, and external morphological data useful for classifying the 9 species of Synophis known to date:
