|Diagnosis||Diagnosis. A small species of the genus, reaching 113 mm maximum TOL (preserved specimens); up to 119 mm TOL in live specimens (Buley et al., 1997). It is a member of the West Indian bilineatus group having two dorsolateral lines, most closely related to Leptotyphlops bilineatus and L. carlae. It differs from both in having a typical pattern of two spots behind the head and a dark tail (Fig. 2A–B). In scale characters it also differs from both species in having a wider PA1 (width/length 2.08–2.28 vs. 1.56–1.93) and a wider PA2 (2.03–2.48 vs. 1.71–2.01). In addition, it differs from L. bilineatus in having a wider SO (0.99– 1.16 vs. 0.78–0.99), a shorter OC (0.63–0.76 vs. 0.78–0.84), and shorter anterior middorsals, PF+FR+IP+IO (2.07–2.28 vs. 2.28–2.55). From L. carlae, it differs in the three characters noted above in the diagnosis of that species. Measurements and scale counts, including those of the holotype, are in Table 1 of HEDGES 2008.|
|Etymology||The species name is dedicated to Michel Breuil for his contributions to the herpetology of the Lesser Antilles.|
