|Comment||Synonymy: Ramphotyphlops/Onychocephalus macrurus PETERS 1860 has been listed as valid species by BAUER 1995, although he states that it has been regarded as a doubtful species by ROUX-ESTÈVE 1974 and as incertae sedis by HAHN 1980. Onychocephalus bicolor PETERS 1858: 509 (= Ramphotyphlops bicolor) has been removed from the synonymy of R. australis by Rabosky et al. (2004). Gray 1845: 135 also cites himself as using Typhlops australis GRAY 1838, citing “The zoology of the voyage of H.M.S. Erebus and Terror”.|
Type species: Anilios australis GRAY 1845: 135 is the type species of the genus Anilios GRAY 1845, by subsequent designation by Stejneger (1904:683).
Taxonomy (genera): Anilios was separated from Ramphotyphlops on the basis of molecular analyses (Hedges et al. 2014; Pyron & Wallach 2014), which recovered Anilios as sister to Acutotyphlops with Ramphotyphlops as outgroup to these. While Acutotyphlops is diagnosable as morphologically distinct from Anilios, the latter genus has not been able to be distinguished from Ramphotyphlops on morphological criteria. Pyron and Wallach (2014), who provide the most detailed morphological comparison, diagnose both Ramphotyphlops and Anilios as being distinguished from all other typhlopoids by a protrusible hemipenis, retrocloacal sacs, and absence of a frontorostral and paired prefrontal scales. The remaining characters mentioned for both genera, including both internal and external features, show extensive overlap between the two genera (for a more detailed discussion see SHEA 2015).
|Etymology||The derivation of the generic name Anilios was not provided by Gray (1845), although Savage and Boundy (2012) suggest it was derived from the Greek ἀν- (lacking) + ἠέλιος (helios, the sun), in reference to the below-ground lifestyle of these snakes. If so, it would be masculine, like Typhlops. Even if it was not derived from these roots (and many of Gray’s names do appear to be meaningless), Gray’s original description suggests a masculine gender for the name. He included six species in the genus. Four of the species names are either genitives (Leachii), based on nouns (ruficauda), or are adjectives that do not differ in termination in male or female gender (australis, nigrescens). The last two names, however, are adjectival, and both were given masculine terminations: ater and squamosus (SHEA 2015).|
