Cuniculus hernandezi Castro, López & Becerra, 2010 is a
name coined for a proposed species of
paca described as an
endemic to the
Central Andes in
Colombia, the only place it has been identified as such to date. Individuals may weigh over , making
C. hernandezi a rather large
rodent. The authors omitted a description of the animal, but it is thought to be very similar to the mountain paca,
C. taczanowskii, from which this taxon was split. According to the authors, analysis of its
mitochondrial DNA and karyotypy indicated that it may be a distinct species. The
specific epithet honours Colombian biologist Dr. Jorge Hernández Camacho. Héctor Ramírez-Chaves and
Sergio Solari, in 2014, argued that the species is not an available name (
nomen nudum) according to the rules of the current
International Code of Zoological Nomenclature (ICZN), due to imprecise definition of the taxon and lack of a
type specimen. Not only is the taxonomy blundered; the original research also used a faulty methodology with limited data to obtain their genetic tree, omitted to publish important results validating (or not) their conclusions, neglected a study of the availability of previously proposed names for pacas found in the region (old synonyms; i.e.
C. serriae in Colombia and Venezuela), and presented no evidence with which to identify the taxon (even the illustrations lack identifications). Although the authors claim that the taxon is easily differentiated by the size of the interparietal bone, they then mention that morphological measurements cannot distinguish the taxon, nor do they provide any evidence to back these assertions. Furthermore, no evidence was presented restricting the taxon to the central Cordilleras. ==References==
