| Diagnosis | Diagnosis: Leptotyphlops fuliginosus is placed in the L. dulcis species group sensu Peters and Orejas-Miranda (1970a), by the presence of supraoculars small, not contacting first supralabial; and generally with the same size or smaller than frontal and postfrontal. The new species can be diagnosed from all members of L. dulcis group, except L. koppesi, by a suite combination of characters: (1) naris located at pupil level, (2) rostral subtriangular in dorsal view, (3) 2+1 supralabials, (4) four infralabials, (5) 10 scales around the middle of tail, (6) maximum total length 303 mm, (7) dorsal colour pattern uniformly dark brown. Refer to table 1 for additional diagnostic features related to South American members of L. dulcis species group. Leptotyphlops fuliginosus differs from L. koppesi (values in parenthesis) in having a rounded snout in dorsal and lateral views (vs. rounded snout in dorsal view and slightly acuminate in lateral view); middorsal scales 198-211 in males, and 210-218 in females (vs. 186-194 in males and 195-208 in females); subcaudal scales 17-20 in males, 14-17 in females (vs. 16- 18 in males and 13-15 in females); up to 303 mmof maximum total length (vs. 337 mm); Coloration: dorsum uniformly dark brown and venter uniformly cream coloured (vs. dorsum uniform pale brown and ventral colour pattern beige with each scale edge white and the center light brown); inferior portion of rostral scale and labial border cream (vs. uniform brown); frontal scale generally slightly wider than supraoculars (vs. slightly smallest or equal supraoculars); posterior margin of rostral generally reaching the imaginary transverse line between anterior margin of eyes (versus not reaching the transverse line between anterior margin of eyes) [from PASSOS et al. 2006]. |
