Distribution | Colombia (Atlántico, Cesar, Cundinamarca, La Guajira, Magdalena, Meta, Santander, Tolima, and Isla Salamanca, elevation 0–1,280 m), Venezuela (Anzoátegui, Aragua, Carabobo, Distrito Federal, Falcón, Lara, Monagas, Nueva Esparta: Isla Margarita, Portuguesa, Sucre, Vargas, and Yaracuy, elevation 0–800 m); Netherlands Antilles (Bonaire, elevation 0–240 m) Type locality: “la vallée de la Magdeleine, à la Nouvelle-Grenade” [= lower Río Magdalena Valley, Departamento de Magdalena, Colombia, ca. 9–11°N, 74–75°W, elevation ca. 25–100 m asl]. |
Reproduction | oviparous |
Types | Holotype: MNHN-RA 1068 |
Diagnosis | Diagnosis. Epictia goudotii is distinguished from all congeners by the following combination of characters: snout truncate in dorsal and ventral view, rounded slightly acuminate in lateral view; supraocular present, not in contact with first supralabial; supraocular abruptly longer than frontal; rostral scale triangular in dorsal view; first supralabial very short and not reaching eye level; ocular hexagonal with straight shape at the eye level; base of ocular scale expanded; temporal indistinct; fused caudals absent; interoccipital indistinct from dorsal scales; two supralabials (1+1); four infralabials; 227–260 middorsal scales; 213–234 midventral scales; 12–16 subcaudal scales; 10 scales around the middle of tail; rostral white pigmented as apical spine or brownish as head coloration; seven dorsal scale rows with dark brown to brown center and lighter border forming longitudinal zig-zag lines; seven ventral scale rows uniformly brown.

Comment | Synonymy: after Wallach 2016. See this paper for more complete chresonomy and references. Mumaw et al. (2016) removed Stenostoma fallax Peters from the synonymy of E. goudotii and recognized E. fallax as the name for the population occurring in northern Venezuela. Wallach 2016: 315 agrees with this assessment; however, he had only one specimen for his analysis and no molecular analysis seems to have been done. Subspecies: Leptotyphlops goudotii ater has been revalidated and elevated to species status by SAVAGE 2002. L. g. bakewelli and L. g. phenops also have been elevated to full species status. Distribution: Not in Central America, including Mexico (Hidalgo, Oaxaca, Tamaulipas), Belize, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama (Wallach 2016, MATA-SILVA et al. 2015). See map in MCCRANIE & HEDGES 2016: Fig. 4. Epictia goudotii previously was considered to inhabit southern Mexico; Central America, including Panama (Smith, 1958b); northern South America, including Colombia, Venezuela, and Trinidad; the offshore islands of Cozumel (Mexico); the Bay Islands [Barbareta, Guanaja, Roatán, and Utila], Cayos Cochinos [Cayo Cochino Grande, Cayo Cochino Pequeño], and Swan Islands [Cisne] (Honduras); Bonaire (Netherlands Antilles); San Andrés and Providencia (Colombia); and Margarita (Venezuela) (Peters et al., 1970; Hahn, 1980; McDiarmid et al., 1999). This species also was reported from Antigua, Grenada, and Watling’s Island in the Caribbean (Barbour, 1930), but these records have been discounted (Powell and Henderson, 2012), and a record for the Suma Islands (Hahn, 1980; McDiarmid et al., 1999) that likely refers to the Exuma Islands in the Bahamas, as once they were called Yumey and Suma (www.bahamas.com/islands/exumas), also is not substantiated. Whether the range of E. goudotii extends to include Trinidad remains to be seen (Murphy, 1997; Boos, 2001), but considering the proximity to the mainland and the short time span since the sea level rise separated Trinidad from Venezuela, E. goudotii conceivably could be present (Wallach 2016: 313). Habitat: In Colombia, Epictia goudotii occurs in shrubland and riverside woodland (Montero-Arias and Quintero-Corzo, 2015). In Venezuela, it inhabits tropical thorny mountains (Rivas-Fuenmayor and Oliveros, 1997), pine savanna (Suárez et al., 2002), and deciduous and semi-deciduous forests on Isla de Margarita (Rivas- Fuenmayor et al., 2005, Wallach 2016: 313). |
Etymology | This patronym is named after the French explorer and naturalist Justin-Marie Goudot, who collected the holotype. From 1822 to 1842, he was a collector in Colombia (at that time known as New Granada) for the Paris Natural History Museum (MNHN). |
