Diagnosis | Diagnosis (genus): Liotyphlops share the following suite of features that separate them from other anomalepidids: enlarged, nonpolygonal head plates that have rounded posterior margins; the enlarged rostral meeting a broad and short frontal plate to completely separate the prefrontals; scale rows at midbody 22 to 28; tail with a terminal spine. Liotyphlops differs from Typhlophis of South America by having enlarged head scales (scales on upper head surface same size and shape as dorsals in Typhlophis) and from the other Costa Rican genera in the enlarged rostral and peculiar frontal scales (Savage 2002: 555, whose diagnosis is based on 7 species known in 2002).

Comment | Type species: Rhinotyphlops albirostris PETERS 1857 is the type species of the genus Liotyphlops PETERS 1881 (which is a substitute name for Rhinotyphlops PETERS, fide WILLIAMS & WALLACH 1989: 87). Synonymy after DIXON & KOFRON 1984. Kaiser et al. 2013 considered the generic names Hawkeswoodus Hoser 2012, Kraussus Hoser 2012 invalid and rejected their use instead of Liotyphlops. Linares-Vargas et al. 2021 resurrected Liotyphlops petersii and Liotyphlops caracasensis. However, specimens and localities of the resurrected species across the range of what these authors redefined as L. bondensis are poorly documented and difficult to track down, without any data presented to show variation or phylogenetic (molecular) data, so we consider the resurrection as a bit preliminary and leave them within albirostris for the time being. For example, the list of 92 specimens provided in Appendix S1 does NOT make any indication which specimen is which species, and Fig. 8 (map) only shows type localities of most species (but not specimens listed in the text or appendix), which is rather confusing, to say the least. Distribution: not in Brazil nor Argentina fide Wallach et al. 2014, and Costa & Bernils 2015. Key: Dixon & Kofron 1984 have a key to the 8 species known in 1984. |
Etymology | Named after Latin “albus, -a, -um” = white and “rostrum” = beak, trunk, or proboscis. The genus was named after the Greek word leios, meaning smooth, and the Greek word typhlops, meaning blind. |
