TYPE SPECIES. — Latentifistula valdeinepta Nazarov & Ormiston, 1985 ( Nazarov & Ormiston 1985: 33; holotype never figured, paratype pl. 3, fig. 9-10).
AGE AND LOCATION OF TYPE MATERIAL. — Lower Permian, Sakmarian Stage, Kandurov Suite, Southern Urals, Sakmar River, Verkhnay Chernaya Rechka Village, Russia.
TAXON CODE. — 194.
STATUS. — Junior synonym of Ormistonella De Wever & Caridroit, 1984 (by De Wever et al. 2001).
DIAGNOSIS. — [As for family] Diagnosis of the Family Paulianellidae : “Dreiarmig. Arme sehr schlank, mit einer Längsfurche, in der eine Porenreihe auftritt. Sonst ist die einschichtige Schale unperforiert. Das Innenskelett besteht aus einer unperforierten Markschale, die einzelne Stacheln aufweist. Von ihr gehen 3 breite, hohle, sehr kurze Arme aus, die zur Wand des Zentralteils des Aussenskeletts zwischen den Armen des Aussenskeletts verlaufen. Diese Arme des Innenskeletts sind aus völlig miteinander verschmolzenen Stachelbüscheln aufgebaut und sie weisen je eine grosse Pore auf. In den Armen tritt kein Innenskelett auf. Das Ende der Arme ist gerundet und weist keine Terminalstacheln auf.” ( Kozur & Mostler 1989: 215).
DIAGNOSIS (English translation by J. P. Caulet – RadWorld database). — “Three arms. Arms slender with a longitudinal depression including a row of pores. Single layered shell otherwise imperforate. Internal framework constituted by an imperforate medullary shell with a single spine. From the shell arise 3 wide, hollow, short arms extending out to the wall of the central part of the external skeleton between the arms. These arms are built by a bundle of completely joined spines with a large pore. Arms with no internal skeleton. Ends of arms blunt with no terminal spines.”
REMARKS
The diagnosis of Ormistonella describes 4 arms not 3, as in Paulianella , but examination of the photo of Ormistonella in Kozur & Mostler, 1989 shows that it is broken so that the 4th arm is missing. The morphology of the arms is the same, and we follow De Wever et al. (2001) in considering Paulianella a junior synonym of Ormistonella .
