CommentSynonymy: The placement of this species remains uncertain until genetic information is available. “The T-III SIP excludes it from the genus Letheobia (which is exclusively T-0 or T-II pattern) and a moderately angled supranasal concavity suggest affinity with Typhlops (which all have a deeply angled nasal, a synapomorphy of Typhlops, Antillotyphlops & Cubatyphlops” (V. Wallach, pers. comm., 19 Dec 2017). Blair Hedges argues that “Typhlops is a Caribbean genus and there is no molecular evidence that it occurs in Africa”, hence we leave coecatus in Letheobia for the time being. 
EtymologyNamed after Latin caecus, coecus = blind or obscured. Apparently for it being a blind snake.
