Lower Cretaceous ammonites from the Neuquén Basin, Argentina: The Hauterivian genus Holcoptychites

Holcoptychites is known only from the Neuquén Basin, Argentina, but appears close to the more widespread genera Jeanthieuloyites and Spitidiscus. Thus it is placed in the subfamily Spitidiscinae (Family Holcodiscidae). Previously described Holcoptychites species are revised and their taxonomy clarif...
