DistributionEcuador (Banos, Abituagua, Balzapamba, Zamora)

Type locality: Ecuador, nr. Baños, 1800 m elevation.  
TypesHolotype: UMMZ 90816, collected by: W. Clarck-McIntyre, August 1939. Paratypes: (n=7) UMMZ 92531, 88897, and 92532, same locality as holotype; UMMZ 90817, 92533-35, 1100 meters, Abitagua, Rio Pastaza Valley, eastern Ecuador. 
DiagnosisDiagnosis: “A large, stout Leptotyphlops allied to macrolepis, differing from it principally in having about 45 fewer median dorsal scales and a uniform black coloration.” (Bailey 1946)

Description: “Head flattened, 5.6 mm. in midth, slightly broader than neck. Total length, 246 mm.; tail, 22 mm.; diameter of body, 6 mm. Scales in 14 rows around the body, 10 rows around the middle of the tail. Median dorsal scales from tip of rostral to caudal spine, 185; median subcaudals, 18, wider than lateral and dorsal caudals; tail terminating in a conical scale provided with a sharp spine. Rostral narrow, slightly constricted at level of nostril, where it measures 1.3 mm, in width, not extending posteriorly to anterior margin of eyes, barely contacting first postrostral scale. Three small subequal median scales following the first postrostral scale, fifth and subsequent median dorsal scales widened. Nasal completely divided, the superior part extending beyond the anterior edge of eye. First labial about two-thirds the height of second, which extends to level of lower margin of eye, its posterior border directly below center of eye. Labio-ocular large, with a posterior projection which is in contact with a temporal scale between the fourth labial and anterior parietal. Supraoculars nearly in contact with each other behind frontal. Parietals in 2 pairs of about equal size. Lower labials, 5. Violet black, except for naso-labials and lower half of rostral, which are dark brown, and the first 3 pairs of lower labials, which are yellowish white.” (Bailey 1946) 
CommentDistribution: Has been mentioned for Colombia but without reliable evidence. Not listed by PEREZ-SANTOS & MORENO 1988 for Colombia. 
EtymologyPresumably named after Greek ἀνθράκινος or “anthrakos” = coal, carbon, after the dark color of the species.
