Typhlops oxyrhinus — HEDGES et al. 2014
Typhlops oxyrhinus — WALLACH et al. 2014: 768 
DistributionCuba (Guantánamo)

Type locality: Bayate (75°21’47’’N, 20°20’07’’W, 338 m elevation), El Salvador Municipality, Guantánamo Province, Cuba.  
Reproductionoviparous (manual imputation, fide Zimin et al. 2022) 
TypesHolotype: CZACC (was CTR) 2230, adult female, collected by Lico Lobaina. Unknown date, although probably in the middle of 20th century. 
DiagnosisDiagnosis: A species of medium size (257 mm maximum TL) of the Typhlops lumbricalis species group, can be distinguished by the combination of its snout pattern (ogival and pointed in dorsal and lateral views, respectively) and having more middorsal scales (.265, 282 mean) than any other Cuban species of the group and T. lumbricalis (Table 1 in DOMINGUEZ & DIAZ 2011). Typhlops oxyrhinus also differs from other species in this group by its narrow oval rostral in dorsal view (0.52–0.60 RWD/RLD), postnasal pattern (strongly divergent), robust tail (1.7–3.2 TA/TD), parietal pattern, and head size. 
CommentSynonymy: Hedges et al. 2019 treat Typhlops oxyrhinus Dominguez & Diaz 2011 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 A comprehensive molecular and morphological review of Typhlops lumbricalis (R. Thomas and S. B. Hedges, unpublished) does not support the regconition of those taxa as described.” 
EtymologyNamed after Greek oxys = sharply pointed and rhinus = snout, in allusion to head with sharply pointed snout.
