Resumen:
In spite of recent interest, the various species belonging to the genera
Heminautilus SPATH, 1927, and Josanautilus MARTINEZ & GRAUGES, 2006,
have never been the object of a general revision. More than 160
specimens belonging to various species of these two genera were studied,
with the aim of identifying the specific characteristics and the
stratigraphical and paleogeographical distribution of the various
species which compose them, as well as to propose a phylogeny for the
group. This study confirms the non-synonymy of H. saxbii (MORRIS, 1848)
and H. lallierianus (ORBIGNY, 1841), establishes that H. tejeriensis
MARTINEZ & GRAUGES, 2006, and H. verneuilli (VILANOVA, 1870) represent
junior synonyms of H. saxbii (MORRIS) and suggests the creation of the
species H. ? japonicus sp. nov. The origin of the genus Heminautilus
SPATH from Pseudocenoceras SPATH, 1927, proposed by TINTANT and the
origin of Josanautilus MARTINEZ & GRAUGES from Heminautilus SPATH are
both confirmed.
