DistributionS Tunisia, Algeria, Morocco, Western Sahara, Mauritania, N Mali, NE Niger, Gambia

Type locality: Hammam Salahin, 6 km au nord de Biskra, Algeria.

natatrix: Gambia; Type locality: Tobo swamp, Gambia.  
Reproductionoviparous 
TypesHolotype: unlocated (McDiarmid et al. 1999: 36), may be in INCDS (fide Wallach et al. 2014: 463), originally in IACB = INCDS (fide M. Sabaj, pers. comm., 21 Nov 2018).
Holotype: NRM = Naturhistoriska Rijksmuseum, Stockholm [natatrix] 
DiagnosisDiagnosis: This race is distinguished from the nominal race by having a much higher middorsal count (528-558 |mean 545.71 compared to 307-329 [mean 316.31 for other African specimens); slightly higher number of subcaudals (45-47 [mean 46.3] vs. 26-42 [mean 35.0] for others); a proportionately shorter tail (L/TL ratio 14.1-17.5 [mean 15.61 vs. 7.9-13.7 [mean 10.81 for other African specimens); and a more elongate body form (L/W ratio 99-138 [mean 114] vs. 49-66 [mean 57] for others). Largest specimen examined measured 287 mm. Asian populations overlap in some characteristics (see Table 1), but none have as great a number of middorsals. (HAHN & WALLACH 1998: 56) 
CommentSynonymy: Has been synonymized previously with Leptotyphlops macrorhynchus (e.g. BOULENGER 1920). Listed in SCHLEICH, KÄSTLE & KABISCH 1996 as synonym of Leptotyphlops macrorhynchus.
