DistributionCuba (Pinar del Río)

Type locality: ‘‘El Liberal’’ coffee plantation (coordinates not known), Cabañas Municipality, Sierra del Rosario, Pinar del Río Province, Cuba.  
Reproductionoviparous (manual imputation, fide Zimin et al. 2022) 
TypesHolotype: CZACC 4.11933, adult male, collected by Eladio Elso in June 1968 (erroneously given as CAZACC on page 206). Paratype: Adult female CZACC 4.19934, same data as holotype. 
DiagnosisDiagnosis: A species of medium size (219 mm maximum TL) belonging to the T. lumbricalis species group, with broader rostral (0.75–0.93 RWD/RLD) than any other Cuban species of the group and T. lumbricalis (Table 1). It can also be distinguished from others in the group by its low middorsal scale counts (265–297), rounded snout in dorsal and lateral views, parietals extending toward the head midline, postnasal pattern (strongly divergent), and head size (HWN/HL and HWN/HWM). 
CommentSynonymy: Hedges et al. 2019 treat Typhlops pachyrhinus 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 A comprehensive molecular and morphological review of Typhlops lumbricalis (R. Thomas and S. B. Hedges, unpublished) does not support the regconition of those taxa as described.”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 pachy = thick, broad and rhinus 5 snout, in allusion to head with very rounded snout.
