Abstract

The taxonomical status of the species in the genus Stellaria Møller, 1832 is reviewed. Prior to this work, the genus included several recent and fossil species, showing considerable morphological variation. This genus is reviewed and Trochus solaris Linné, 1764 and Stellaria solaris paucispinosa Kosuge & Nomoto, 1972 are retained in it. The latter taxon is here elevated to species level.Trochus chinensis Philippi, 1841, Trochus infundibulum Brocchi, 1814, Tugurium makiyamai Itoigawa & Nishikawa, 1976, Tugurium subextensum var. ornatoparva Sacco, 1896, Xenophora dunkeri Martin, 1879, Xenophora gigantea Schepman, 1909, Xenophora lamberti Souverbie, 1871, [Xenophora] (Tugurium) plioitalicum Sacco, 1896, Xenophora (Trochotugurium) subagglutinans Glibert, 1938 and Stellaria striatissima Raven, 2021 are assigned to Aspidophoreas gen. nov. Xenophora digitata von Martens, 1878 and Xenophora (Stellaria) testigera profunda Ponder, 1983 are elevated to species level, and together with the fossil species Phorus testigerus Bronn, 1831, Xenophora cleopatrae Cuvillier, 1933, Xenophora conica Dall, 1892 and Stellaria kriegerbartholdi Nielsen & DeVries, 2002, they are assigned to Ponderiana gen. nov. The main morphological characters
of the new genera are described.

Key words
Ponderiana, Aspidophoreas, new genera.

Riassunto

Viene revisionato lo stato tassonomico delle specie incluse nel genere Stellaria Møller, 1832. Prima di questo lavoro, il genere includeva diverse specie recenti e fossili, che mostravano una considerevole variabilità morfologica. Qui viene revisionato il genere e Trochus solaris Linné, 1764 e Stellaria solaris paucispinosa Kosuge & Nomoto, 1972 vengono assegnati ad esso. Quest’ultimo taxon viene elevato a livello specifico.
Trochus chinensis Philippi, 1841, Trochus infundibulum Brocchi, 1814, Tugurium makiyamai Itoigawa & Nishikawa, 1976, Tugurium subextensum var. ornatoparva Sacco, 1896, Xenophora dunkeri Martin, 1879, Xenophora gigantea Schepman, 1909, Xenophora lamberti Souverbie, 1871, [Xenophora] (Tugurium) plioitalicum Sacco, 1896, Xenophora (Trochotugurium) subagglutinans Glibert, 1938 e Stellaria striatissima Raven, 2021 vengono assegnate a Aspidophoreas gen. nov. Xenophora digitata von Martens, 1878 e Xenophora (Stellaria) testigera profunda Ponder, 1983 vengono elevate a livello specifico, e insieme alle specie fossili Phorus testigerus Bronn, 1831, Xenophora cleopatrae Cuvillier, 1933, Xenophora conica Dall, 1892 e Stellaria kriegerbartholdi Nielsen & DeVries, 2002, vengono assegnate a Ponderiana gen. nov. Le principali caratteristiche morfologiche dei nuovi generi vengono descritte.
