Diagnosis | Diagnosis (genus). Species of Typhlops have (1) eye, distinct, (2) snout, rounded, (3) head scale arrangement, non-circular, (4) frontorostral, absent, (5) nasal, completely divided (rarely incomplete), (6) nasal suture origin, supralabial 2, (7) suboculars or subpreoculars, absent (rarely present), (8) postoculars, 2 (rarely 1 or 3; average, 1.85), (9) preocular-labial contact, supralabial 3 (rarely none), (10) midbody scale rows, 18 or 22 (average, 20.0), (11) scale row reduction, present or absent, (12) total scale rows, 231–457 (average, 312), (13) caudals, 8–19 (average, 13.1), (14) maximum total length, 126–445 (average, 243) mm, (15) total length/midbody diameter, 23–57 (average, 35.9), (16) total length/tail length, 18–88 (36.8), (17) dorsal color, always pigmented, brown or tan, (18) ventral color, unpigmented (pinkish), white, or cream, (19) dorsum darker than venter, and (20) overall, lacking any distinctive pattern (spots, lines, or stripes), although rarely a faint trace of a dorsal line (Tables 1–2); molecular phylogenetic support (Figs. 1, 3). Among its closest relatives (Figs. 1, 3), Typhlops is distinguished from Cubatyphlops by the presence of 2 postoculars (versus 1; except in 3 species of Typhlops with 1 postocular) and preocular contact with supralabial 3 only (versus contact with supralabials 2 and 3 in Cubatyphlops) (Table 2). The same distinction holds for Typhlops versus the more distantly related Amerotyphlops, although 4 species of that latter genus have more than 1 postocular (Thomas 1968; 1976; Dixon & Hendricks 1979; Thomas & Hedges 2007). Typhlops and Antillotyphlops require closest comparison. Thomas (1989) found that species placed here in the genus Typhlops formed a group separate from species placed here in Antillotyphlops based on reduction of the basihyal and a lower number of total middorsal scale rows. He excluded T. jamaicensis and T. sulcatus from that definition, but the molecular data place those two species together with others in Typhlops sensu stricto [HEDGES et al. 2014: 47].

Comment | Type species: Anguis lumbricalis LINNAEUS 1758: 228 is the type species of the genus Typhlops SCHNEIDER in OPPEL 1811. Type genus: Typhlops is the type genus of the subfamily Typhlopinae and the family Typhlopidae. Phylogenetics: for a phylogenetic analysis of Typhopidae see Sidharthan & Karanth 2021. Synonymy: Typhlops silus LEGLER 1959 has been removed from the synonymy of T. lumbricalis. Kaiser et al. 2013 considered the generic names Acetyphlops Hoser 2012, Altmantyphlops Hoser 2012, Arnoldtyphlops Hoser 2012, Copelandtyphlops Hoser 2012, Crottytyphlops Hoser 2012, Dannytyphlops Hoser 2012, Edwardstyphlops Hoser 2012, Eippertyphlopea Hoser 2012, Elliotttyphlopea Hoser 2012, Freudtyphlops Hoser 2012, Goldsteintyphlops Hoser 2012, Judywhybrowea Hoser 2012, Katrinhosertyphlops Hoser 2012, Lenhosertyphlops Hoser 2012, Mosestyphlops Hoser 2012, Nintyphlops Hoser 2012, Pillotttyphlops Hoser 2012, Rentontyphlops Hoser 2012, Rolyburrellus Hoser 2012, Ronhoserus Hoser 2012, Woolftyphlops Hoser 2012 invalid and rejected their use instead of Typhlops. Typhlops (Diaphorotyphlops) disparilis JAN, in JAN & SORDELLI 1860-1866 is a species of unknown status and thus listed under “species inquirenda” by several authors, e.g. WALLACH et al. 2014: 837, (following Hahn 1980: 76), MCDIARMID, et al. 1999: 125 etc. It’s distribution and type locality are unknown (according to HAHN 1980) and the type destroyed. However, the species has been mentioned in a few papers, e.g. as Diaphorotyphlops disparilis (PETERS 1881: 70) or Typhlops disparilis (BOULENGER 1893: 53). Illustrations: Vogel, 1965; Vogel, 1966; Thomas, 1974; Thomas, 1976. When A. lumbricalis was published this taxon was composite of two names currently used for two distinct species, Typhlops lumbricalis from the Cuban archipelago and the Bahamas and Typhlops jamaicensis (Shaw, 1802) from Jamaica. The now-nominal species Anguis jamaicensis was based on two of the references cited by Linnaeus and the name jamaicensis is a replacement name for lumbricalis. Distribution: restricted to the Bahamas Islands by DOMINGUEZ & DIAZ 2011. Populations from other localities have been assigned to other species by DOMINGUEZ & DIAZ 2011. The species has previously been reported from Cuba, Isla de la Juventud, Hispaniola, Bahamas, Guyana (introduced), Jamaica (BARBOUR 1910), and the USA (Florida and Puerto Rico). Records of this species from Guyana and Florida, USA, are based in specimens stored in museums (e.g., Myers, 1958; Peters and Orejas– Miranda, 1970). These records are mistakes because they were based on misidentifications and erroneous locality data (Dixon and Hendricks, 1979; McDiarmid et al., 1999). Morphology: for morphological data across the species in this genus see Pyron & Wallach 2014: Table 2. Key: to West Indian Typhlops: Thomas 1989: 418. |
Etymology | Named after Latin lumbricus = earthworm, based on the similarity to earthworms and their fossorial life style. The genus name, a masculine noun, is Greek (”typhlos”), meaning ‘blind’ from (”typhl-” = blind + ops = eye). The genus name is feminine (fide Savage 1950). |
