Current identification/main database link: Sigalia decoratissima (De Klasz, 1953)
Translated using Google translate from German. Original text below Diagnosis: A Ventilabrella with the following special feature: The chamber septa of the two-line initial stage are decorated with raised lumps. Description: The chambers of the test are initially in two lines, fan-shaped in the later stage. The number of two-line, elongated initial chambers is up to 7-8 on each side. The curved sutures of these chambers are ornamented with raised lumps standing in a row, which are slightly elongated across the ventricular septum. The sutures of the following fan-shaped chambers show little or no granulation. Below these chambers are cut off by the arcuate upper parts of the preceding chambers. Due to the strong ornamentation of the biserial part of the test it appears thicker in side view, than the adult part with the arranged fan-shaped chambers. Translated using Google translate from German. Original text below Relationships: The form differs from all other species of the genus by their strong ornamentation. It differs from its closely related "Gümbelina (Gümbelina, Ventilabrella) deflaensis" Sigal (nomen nudum) by its stretched along the longitudinal axis of the housing node on the ventricular walls of the two-line stage. Gümbelina deflaensis shows only a longitudinal striation from the chambers (see Fig. In Sigal 1952, p. 37, Fig. 41). Remarks: A very characteristic of the lowest Buchecker layers. Often one finds only the two-line form
Original Description
Beschreibung : Die Kammern des Gehäuses sind anfangs zweizeilig, im späteren Stadium fächerförmig angeordnet. Die Zahl der zweizeiligen, länglichen Anfangskammern beträgt bis zu je 7-8 an beiden Seiten. Die gebogenen Suturen dieser Kammern sind mit erhabenen, in einer Reihe stehenden Knoten verziert, die quer zur Kammerscheidewand ein wenig in die Länge gezogen sind. Die Suturen der folgenden, fächerförmig verteilten Kammern zeigen nur wenig oder gar keine Körnelung. Unten werden diese Kammern durch die bogenförmigen oberen Teile der vorhergehenden Kammern abgeschnitten. Der biseriale Teil des Gehäuses erscheint in Seitenansicht infolge der starken Ornamentierung dicker als der adulte Teil mit den fächerförmig angeordneten Kammern.

Bemerkungen : Eine sehr bezeichnende Art der untersten Buchecker Schichten. Oft findet man nur die zweizeilige Form
