Une collection exceptionnelle de Diplostraca (Spinicaudata, Leaiina), provenant de nombreux gisements mondiaux et d’une période géologique s’étendant du Dévonien au Jurassique, est révisée dans ce catalogue. Le travail des deux chercheurs, S. Defretin et N. Novozhilov, ayant contribué à constituer cette collection durant une période difficile (la guerre froide), conserve sa pleine importance scientifique, moyennant quelques précisions que ce catalogue tente d’apporter. Notre compilation permet aussi d’alimenter les discussions actuelles sur plusieurs taxons : Estheriina, Pseudoasmussia, Taimyrites, Fernandoalmeidium, Pseudestheria, et Teixeirium. Notre travail devrait déboucher sur des révisions, fondées sur les méthodes modernes de la taxinomie, d’espèces encore incomplètement élucidées : “Estheria” destombesi, “Lioestheria” toricata, “Lioestheria” propinqua et “Pseudoasmussia” striata. Le point scientifique le plus intéressant, abordé dans ce catalogue, concerne l’ordre des Spinicaudata, que notre matériel permet de suivre depuis ses premières formes du Dévonien-Carbonifère.
An exceptional collection of Diplostraca (Spinicaudata, Leaiina) from various geographic localities all around the world and from Devonian to Jurassic beds, is re-described in this catalogue. Despite some imperfections due to the geopolitical climate of the epoch (the Cold War), the great value of the Defretin’s and Novozhilov’s work is confirmed. New interpretations are provided about discussed taxa: Estheriina, pseudoasmussia, Taimyrites, Fernandoalmeidium, Pseudestheria, and Teixeirium. Used as a reference work, this catalogue might permit these taxa to be reviewed in light of new methodologies and taxonomic schemes currently employed. Some species remain enigmatic, “Estheria” destombesi, “Lioestheria” toricata, “Lioestheria” propinqua and “Pseudoasmussia” striata, but offer a great possibility of revision by means of the data of this catalogue. The early record of Devonian-Carboniferous spinicaudatans in our collection is noteworthy, and provides important information on the early diversification of this group.
