Descripción
Plagiodontes rocae Doering 1881 is a strictly endemic species from the Paleozoic mountains of southern Buenos Aires province (Argentina). Its identity has been never controversial, but its description and discrimination from related species was still incomplete. A quantitative analysis of its measurements was advisable to locate the species in the frame of a morphological re-analysis of all species in genus Plagiodontes Doering1876. In this study, Protoconch sculpture is illustrated by SEM micrographs to rectify previous descriptions. Shell measurements and angles are studied by Multivariate Discriminant Analysis to discriminate it from other small-sized species. Genital anatomy of P. rocae is described for the first time, its quantitative data being discriminated by multivariate methods from those of the only co-existing Odontostominae, i.e., Plagiodontes pat-agonicus.
Plagiodontes rocae Doering 1881 ist eine endemische Art des paläozoischen Berglandes im Süden der Provinz Buenos Aires, Argentinien. Ihr Status als eigenständige Art ist nie in Frage gestellt worden, doch ist ihre Beschreibung und Differenzierung von nahestehenden Arten nicht abgeschlossen. Im Rahmen der Revision aller Plagiodontes-Arten, die wir derzeit durchführen, ist daher eine morphometrische Analyse angebracht, um die Art korrekt einzuordnen. Die Skulptur des Embryonalgehäuses wird mittels SEM-Mikrographie dargestellt. Gehäusemaße und -winkel werden mit Hilfe der Multivariaten Diskriminanzanalyse mit denen anderer kleingehäusiger Arten verglichen. Die Genitalanatomie von P. rocae wird hier zum ersten Mal beschrieben; ihre morphometrischen Daten werden mit Hilfe der Multivarianzanalyse mit P. patagonicus, des einzigen sympatrischen Vertreters der Odontostominae, verglichen.
