Pentaspongoreta, nomen novum for the genus Anachoreta O’Dogherty, 1994 (Radiolaria), non Gistel, 1848 (Hymenoptera)

Abstract. In 1994, O’Dogherty (p. 137) erected the genus Anachoreta for a distinctive multicyrtid radiolarian having pentagonal post-abdominal segments in cross-section, a feature hitherto unknown among Cretaceous nassellarians. This monospecific taxon is a useful stratigraphical marker, ranging from the latest Albian to Middle–Late Cenomanian times. Recently, it was discovered that Gistel (1848) first gave the same name Anachoreta to an insect of the suborder Symphyta (Hymenoptera) as replacement name pro Lophyrus Latreille, 1802, previously preoccupied. Therefore, in accordance with the International Code of Zoological Nomenclature (1999) (Article 60), the name Pentaspongoreta is herein proposed as a replacement (type species Anachoreta sagitta O’Dogherty, 1994, p. 138, by original designation) for the preoccupied homonym Anachoreta O’Dogherty, 1994, non Gistel, 1848. Pentaspongoreta is named for its pentahedrical-shaped test and spongy meshwork; feminine gender.
