Taxonomy
Argentinolycus Was first proposed as a monotypic genus in 2012 by the Argentinian zoologists Jesús Matallanas and Cecília Corbella.[2] Its only species, Argentinolycus elongatus, was originally described in 1898 as Phucocoetes variegatus forma elongatus by the Swedish zoologist Fredrik Adam Smitt who gave Puerto Madryn in Argentina as the type locality.[3] when this species was moved from the genus Iluocoetes, that genus had to be redescribed as the description of the genus was based on this taxon rather than the type species. Iluocoetes is now monospecific too.[5] This genus is classified within the subfamily Lycodinae, one of 4 subfamilies in the family Zoarcidae, the eelpouts.[4]
