DiagnosisDiagnosis (genus): Species in this genus have 16 midbody scale rows, 14 midtail scale rows, 302–546 middorsal scale rows, 21–30 subcaudals, 2–4 supralabials, small anterior supralabials, 160–460 mm maximum adult total length, a body shape of 67–160 (total length/width), a relative tail length of 3.7–10.0 %, a tail shape of 3.5, no striped pattern, a brown dorsum, and brown venter (Table 2). They are distinguished from the other genus in this tribe, Guinea, by having 16 midbody scale rows (versus 14), 14 midtail rows (versus 12), 302–546 middorsal rows (versus 173–288), 21–30 subcaudals (versus 6–16), and a body shape of 67–160 (versus 24– 69.2). Only one species was included in the molecular phylogenetic analyses (Figs. 3–4). [from ADALSTEINSSON et al. 2009].

CommentType species: Typhlops koniagui VILLIERS 1956 is the type species of the genus Rhinoleptus Orejas-Miranda, Roux-Estève, and Guibé, 1970. 
EtymologyThe genus name is masculine and derived from the Greek noun rhinos (nose) and Greek adjective leptos (thin), in allusion to the unusual rostral scale of Rhinoleptus koniagui, with its narrow and pointed anterior tip.
