CommentAbundance: only known from its original description (Meiri et al. 2017). 
EtymologyThe specific name of the new species is a transliteration of the Greek μεταλλουργος (metalloyrgos), meaning “miner” (Liddle and Scott 1996). It is here used as an adjective that agrees in gender with the generic name. The name refers to the fossorial habits of amphisbaenians, which use the head to dig underground tunnels like a miner. Paradoxically, this new “mining reptile” was found in the area where a slurry pipeline is being installed. “Miner” is also the translation of the Portuguese words “mineiro” and “mineira”, masculine and feminine adjectives referring to native inhabitants of the state of Minas Gerais, where the new species was discovered.
