Hedges et al. (2014) and Pyron & Wallach (2014) split the family Typhlopidae into several genera on the base of molecular and morphological analyses. Anilios has been resurrected for the Australian blind snakes previously included in Ramphotyphlops. Recognition of the two genera is needed in order to avoid paraphyly, allowing the non-Australian genus Acutotyphlops, which is both morphologically and genetically distinguishable from Ramphotyphlops and Anilios, to be recognised. However, a significant number of Australian species have not been included in such analyses and their assignment to Anilios is merely based on geography. No morphological character differentiates the two genera (Shea 2015). According to Pyron & Wallach (2014), Ramphotyphlops and Anilios "...can be distinguished from all other typhlopoids by a protrusible hemipenis, retrocloacal sacs, and absence of a frontorostral and paired prefrontal scales ", while the remaining characters mentioned for both genera, including both internal and external features, show extensive overlap and turn out to be useless (see Shea 2015).
Savage & Boundy (2012) provide evidence that the gender of Anilios is masculine, a position confirmed by Shea (2015) although on different grounds.

Shea (2015) clarifies that some emendations proposed by McDiarmid et al. (1999) (Ramphotyphlops leptosomus) and later by Hedges et al. (2014) and Pyron & Wallach (2014), namely A. aspinus, A. leptosomus, A. micromma and A. nigricaudus (here treated as synonym of A. guentheri) are invalid. They are all nouns, not adjectives, and therefore must be kept in their original spelling, in accordance with art. 31.2.1.-2 of ICZN.
