|Diagnosis||Diagnosis. Ninia teresitae can be distinguished from all congeners by the following combination of characters: ventral surfaces of head and body spotted without regular pattern (Fig. 3), subcaudal surface homogenously black or dark brown; two nasal scales; bilobed hemipenis (50−74% respect to hemipenial body); centrifugal, bifurcation of the sulcus spermaticus proximal to midpoint of the hemipenial body; lateral projection ornamented with a large basal hooked spine that is larger than any other spine on the hemipenial body.|
Comparisons. Ninia teresita was previously identified as N. atrata and N. maculata by Castaño-M et al. (2004). Nevertheless, conspicuous characters distinguish it from both these species, such as the uniformly black or dark brown dorsal ground color (vs. dark body bands in N. maculata), ventral surfaces of head and body spotted without regular pattern, chin surface black or dark brown (vs. ventral surfaces of head and chin homogeneously cream in N. atrata or arranged in checkered patterns in N. maculata); subcaudal surface homogenously black or dark brown (vs. subcaudal surface cream in N. atrata, or arranged in checkered pattern in N. maculata), hemipenis with a lateral projection ornamented with a large basal hook-shaped spine that is larger than any other spine on the hemipenial body (vs. hemipenial body without lateral projection), and two nasal scales (vs. one nasal scale in N. atrata) (Table1).
|Comment||Synonymy: This species has been reported as a distinct population of N. maculata or as N. atrata from the western slopes of the Cordillera Occidental of Colombia.|
|Etymology||The specific epithet teresitae represent the Latin translation of the nickname from the Spanish “Teresita” and is given in honor to the grandmother of the first author, Maria Teresa Guerrero (1915−2013). “Teresita” was one of the most influential persons in her grandson’s life, who never failed to support him and encouraged his endless passion for snakes.|
