A New Genus Arabitrigonia nov.
NAKANO Mitsuo
Abstract
In this paper, the writer proposed Arabitrigonia nov. based on Trigonia pseudocrenulata NOETLINO. This new genus is one of the most aberrant and interesting Trigoniids, and may be an offshoot derived from Pseudomyophorella by the development of the Pterotrigonia-type shell form and surface ornament.
