|Types||Holotype: ICN-MHN = ICN 5730, Adult male, collected by R. Hernández. Paratype. Juvenile female, UIS R 1705, Cerro de La Paz (6°58’20”N, 73°26’ 18”W; 2324 m elevation) collected by E. Brisceño at municipality of Zapatoca, department of Santander, Colombia (Figs. 4, 5B).|
|Diagnosis||Diagnosis. Imantodes guane is distinguish from all congeners by the combination of the following characters: smooth dorsal scale rows 17/17/15; apical pits absent; infralabials 12–13; ventrals 227–236; subcaudals 147–148; loreal scale present; cloacal plate divided; dark brown temporal stripe between the lower edge of temporal scales and upper region of supralabials; dorsum of body light brown with dark brown transversal streaks, weakly evident in lateral view; hemipenis in situ extending to the level of 11th subcaudal and reaches the 10th subcaudal when everted; hemipenis with sulcus spermaticus laterally expanded inside capitulum.|
Comparisons. Imantodes guane differs from I. lentiferus by having 17 dorsal scale rows anteriorly and at the midbody (vs. 15); from I. cenchoa, I. gemmistratus, and I. tenuissimus by having color pattern light brown with dark brown transversal streaks, weakly evident in lateral view (vs. well defined body blotches with shape of wide saddles); differs from I. cenchoa, I. gemmistratus, and I. inornatus by having 12–13 infralabials (vs. 8–11, 9–10 and 8–11, respectively); differs from I. inornatus by having 227–236 ventrals and 147–148 subcaudals scales (vs. 196–218 ventrals and < 140 subcaudals); differs from I. phantasma by the presence of a dark brown temporal stripe (vs. absence of a dark pigmentation on temporal region), dorsum of the head light brown with dark brown blotches (vs. dorsum of the head orangish brown mottled with grayish brown), and 147–148 subcaudals (vs. > 150 subcaudals); differs from I. chocoensis by presence of loreal (vs. absence of loreal), presence of dark brown temporal stripe (vs. absence of a dark brown temporal stripe), dorsal scale rows with posterior reduction to 15 rows (vs. dorsal scales without reduction), and cloacal plate divided (vs. cloacal plate entire). Refers to Table 1 for additional morphological characters differing Imantodes guane from remaining species in the genus [MISSASSI & PRUDENTE 2015].
|Etymology||The specific epithet “guane” alludes to the name given to indigenous people that lived in the northeast region of the Colombia, where the new specimens were collected. This native Indians occupied the margin of the Fonce and Suárez Rivers, to the left margin Sogamoso river, in Cañon of Chicamocha. The men of the tribe would have their skulls deformed from the birth to the first year of life by using splints in the frontal and posterior surface of the skull. The resulting cranial shape denominated “tabular oblique deformation” reminds of the elongated head typical of the genus Imantodes.|
