Deflandrella De Wever & Caridroit, 1984
Deflandrella De Wever & Caridroit, 1984: 99 .
TYPE SPECIES. — Deflandrella manica De Wever & Caridroit (monotypy; De Wever & Caridroit 1984: 99, pl. 1, fig. 1-7) .
AGE AND LOCATION OF TYPE MATERIAL. — Upper Permian, Kamigori Belt, SW Japan.
TAXON CODE. — 171.
STATUS. — Homonym (by Caridroit et al. 1999).
DIAGNOSIS. — “ Deflandrellidae à 3 tubes coplanaires. La position des spicules internes permet la distinction d’un plan de symétrie bilatéral perpendiculaire au plan des bras. Dans ce dernier, l’une des épines émerge du milieu du tube (elle appartient au plan de symétrie bilatérale), les deux autres émergent du bord du tube (du côté le plus éloigné du plan de symétrie). La paroi de la coque est lisse et imperforée ou presque. La structure interne est particularisée par des cloisons transverses réparties régulièrement le long des tubes. Les chambres (ou segments) ainsi délimitées communiquent entre elles par une ou deux petites perforations des cloisons.” ( De Wever & Caridroit 1984: 99).
DIAGNOSIS (English translation by J. P. Caulet – RadWorld database). — “ Deflandrellidae with 3 co-planar tubes. The distribution pattern of the internal spines permits to distinguish a plane of bilateral symmetry that is perpendicular to the plane of arms. In this plane, one of the spines outgrows from the middle of the tube (it pertains to the plane of bilateral symmetry), the others outgrow from the rim of the tube (on the farther side to the plane of symmetry). Shell wall smooth and almost not perforate. Internal structure segmented by transversal septa regularly distributed inside the tubes. Chambers (or segments) communicating through one or two small pores in the septa.”
REMARKS
Cauletella is the replacement name because Deflandrella is a junior homonym of the modern plagiacanthid nassellarian Deflandrella Loeblich & Tappan, 1961 . See remarks by Caridroit et al. (1999).
