|Diagnosis||Diagnosis. The small size (< 215 mm TL), a single preocular in contact with third supralabial only, 20 anterior scale rows reducing posteriorly to 18 scale rows, and < 310 middorsal scale counts associates Typhlops leptolepis with species in the Typhlops lumbricalis species group: T. lumbricalis (Bahamas Islands); T. oxyrhinus and T. pachyrhinus (Cuba); T. schwartzi, T. tetrathyreus, and T. titanops (Hispaniola).|
The new species can be distinguished from other species in the group by its narrow oval rostral (0.45–0.60 RWD/RLD) in dorsal view with parallel to curved sides, a strong tapering toward anterior tip (Fig. 1), and a distinctive dark umber coloration. It also differs in having a venter color undifferentiated from dorsum, head and neck coloration differentiated from body in ventral view, and a white spot ventrally covering the tail and cloacal opening (Fig. 2).
Typhlops leptolepis also differs from those species by a combination of characters (Table 1), e.g. body size, thin body, snout pattern, number and size of the parietals and occipitals, number of postoculars, divergent postnasal pattern, moderate to high middorsal scale counts (> 250, 278 mean), and reduction of the anterior scale rows at midbody or posterior to midbody (67% TL maximum, 57% mean).
|Comment||Synonymy: Hedges et al. 2019 treat Typhlops leptolepis Dominguez et al. 2013 as synonymn of Typhlops lumbricalis “because an insufficient sampling of museum material was used to diagnose them. A comprehensive molecular and morphological review of Typhlops lumbricalis (R. Thomas and S. B. Hedges, unpublished) does not support the regconition of those taxa as described.”|
|Etymology||In Greek lepto = narrow and lepis = scale, in allusion to distinctive rostral pattern in dorsal view.|
