| Diagnosis | Diagnosis (genus): Sundatyphlops can be unambiguously diagnosed from Anilios by a combination of just two characters: midbody and middorsal scale rows. For example, of the ten species of Anilios having the same number of midbody scale rows (22) as Sundatyphlops, none has middorsal scale row counts that overlap with those of Sundatyphlops (453–496), as shown in Table 2 of Pyron & Wallach (2014). Thus, Sundatyphlops is morphologically diagnosable, phylogenetically distinct and should be considered as a valid genus [NAGY et al. 2015]. |
| Comment | Subspecies: according to HAHN 1980 and de LANG 2011, although the status of these subspecies seems to be unclear. See Iskandar 2001 (Treubia) for details. De Lang (2011) states that florensis and polygrammicus are so alike that it is impossible to distinguish them. Synonymy: note that the Australian and Papuan populations of the former Typhlops polygrammicus have been split off into what is now Anilios torresianus by HEDGES et al. 2014. Typhlops bipartitus SAUVAGE 1879 has been removed from the synonymy of T. polygrammicus by PYRON & WALLACH 2014. NAGY et al. 2015 revalidated Sundatyphlops. However, since it is a basal member of the Anilios clade, we leave it within Anilios for the time being. Distribution: not in Australia (Queensland) as reported previously (e.g. Waite 1918, Cogger 2014: 809). The populations in Queensland are now considered to be A. torresianus. Type species: Typhlops polygrammicus SCHLEGEL 1839: 40 is the type species of the genus Sundatyphlops HEDGES et al. 2014. |
| Etymology | The generic name is a masculine noun formed from the adjective sundanus (a, um; i.e., ‘from Sunda’) and the Greek noun typhlops (the blind). |
