Type species: Typhlops pammeces GÜNTHER 1864 is the type species of the genus Indotyphlops HEDGES et al. 2014.
Diagnosis (genus). Species of Indotyphlops have (1) eye, distinct (sometimes indistinct), (2) snout, rounded, (3) head scale arrangement, non-circular, (4) frontorostral, absent, (5) nasal, completely or incompletely divided, (6) nasal suture origin, 2nd supralabial (sometimes preocular, or rarely 1st supralabial), (7) suboculars or subpreoculars, absent, (8) postoculars, 1 in all 18 species recorded, but variable (1–2) in 1 of those species, (9) preocular-labial contact, supralabials 2 & 3 (sometimes 3rd only), (10) midbody scale rows, 18–20 (22 in 1 species; average, 19.4), (11) scale row reduction, absent (sometimes present), (12) total scale rows, 229–468 (average, 345), (13) caudals, 7–15 (average, 10.8), (14) maximum total length, 91–285 (average, 175) mm, (15) total length/midbody diameter, 28–130 (average, 57.6), (16) total length/tail length, 22.3–76 (average, 46.4), (17) dorsal color, shades of brown (sometimes cream, gray, yellowish-brown, reddish brown, lavender-gray, or black), (18) ventral color, variable (white, cream, pale brown, lavender-gray), (19) dorsum darker than venter, (20) overall, uniform, but often with a darker median row of scales giving a slight lineate appearance (Tables 1–2); molecular phylogenetic support (Fig. 1).
From other genera of Asiatyphlopinae, Indotyphlops differs in having a single postocular (versus 2 or more). Exceptions are Cyclotyphlops, 3 species of Anilios, and 3 species of Ramphotyphlops. It also has the lowest number of midbody scales (19.4 versus 20.1–30.4 in others; averages), and no scale reduction (6 of 7 species recorded; versus reduction present in Acutotyphlops, Cyclotyphlops, Malayotyphlops, Grypotyphlops, and Xerotyphlops). In total length, Indotyphlops is one of the smallest genera (TL = 175 mm versus > 243 mm in all others except Cyclotyphlops). It is also the thinnest genus in the subfamily (TL/MBD = 57.6 versus < 56 in other genera). Indotyphlops lacks yellow on the venter (except one species) whereas Asiatyphlops, with which it is broadly sympatric, has yellow on the venter [HEDGES et al. 2014: 37]. For an alternative diagnosis see PYRON & WALLACH 2014: 56.
|Etymology||The generic name is a masculine noun formed from the adjective indianus (a, um; i.e., ‘from India’) and the Greek noun typhlops (the blind).|
