Resumen:
The Family Glyptodontidae Gray
traditionally includes five subfamilies (i.e. Glyptatelinae Castellanos, Propalaehoplophorinae Ameghino, Doedicurinae
Trouessart, Glyptodontinae Gray, and Hoplophorinae Huxley). Hoffstetter
carried out this phylogenetic and taxonomic synthesis, which was accepted by
most of authors. Since some years ago, this original proposal does not concord
with modern contributions based on phylogenetical analyses, which recognize
news lineages; in addition, several taxa usually interpreted as monophyletic
are in fact no natural groups, such as Hoplophorinae. This subfamily was
divided by Hoffstetter in seven tribes (Palaehoplophorini,
Plohophorini, Panochthini, Lomaphorini, Neothocoraphorini, Neuryurini,
and Hoplophorini) using as main diagnostic character the presence of a well
developed caudal tube. In this
contribution we reaffirms, through a cladistic analysis incorporating all the
species of the genus Neosclerocalyptus
Paula Couto, the usage of the term Neosclerocalyptini to include Neosclerocalyptus. On the other hand, a
phylogenetic analysis incorporating all the taxa that traditionally were
included in the tribe Panochthini (Nopachthus
Ameghino [two species], Propanochthus
Castellanos [one species], and Panochthus
Burmeister [seven species]) indicates the polyphyletic condition of
Panochthini whereas Panochthus is a
natural group, being Hoplophorus the
sister taxa. Thereby, we propose the usage of Panochthini to include the genera
Panochthus and Hoplophorus.
