DiagnosisDiagnosis: Phymaturus yachanana sp. nov. is a robust and medium sized member of the clade referred as the patagonicus group by Etheridge (1995), because it has flat imbricate superciliaries, non-rugose dorsal scales on tail, and subocular scale usually not fragmented. This new species is allopatric and differs from all other members of the clade in its unique dorsal pattern of mid-dorsal small white dots occupying only 1-8 scales and larger lateral dots or bands (3–27 scales) on a brown background. 
CommentGroup: calcogaster species group

Abundance: only known from its original description (Meiri et al. 2017). 
EtymologyThe specific name, “yachanana”, means "with abundant iron ore" in the language of the northern Tehuelches, a native group that inhabited the region of the type locality (yacha =means iron ore, nana= abundant). This name was used for a locality near Sierra Grande hills by the Swiss naturalist and explorer Jorge Claraz during his travels to the region in the summer of 1865–1866 (Casamiquela 1998, see p. 162). Sierra Grande hills harbor the only one iron mine of Argentina.
