6F7EC575590C4D77FF777ECF9EDFA3A3.taxon	discussion	Remarks. Te type material of the type species is not available. According to the author of the genus, Fromentel (1861), the genus has the same structure as Microsolena Lamouroux, 1821 but differs by the presence of a central corallite and subsequent corallites that are arranged in rows. Pandey et al. (1999) contribute to the knowledge of the genus.

It can only be compared to T. melania because the lectotype of T. melania (MNHN M 03534) has only 98 septa. Tis species was originally described from the Upper Oxfordian of Champlitten (France, Haute-Saône). Te present specimen also compares to T. tourtiensis (Bölsche, 1871) but that species has much smaller corallite dimensions.	en	Löser, Hannes, Wetzel, Andreas, Hostettler, Bernhard (2024): Callovian corals from the Swiss Jura.

6F7EC57559044D7CFCCD7BD39ADFA7E5.taxon	discussion	Remarks Te genus Montlivaltia is one of the most species-rich genera in the Jurassic and Cretaceous with 224 species in the Jurassic and 74 in the Cretaceous (Lathuilière, 1989; Löser, 2000). It seemed to be always easier to establish a new species in place to compare own material to the vast number of existing taxa (Lathuilière, 1988). A correct taxonomic comparison is therefore difficult and must restrict to species where the type material was available for study. Te present specimen compares well to the two syntypes of Montlivaltia icaunensis. Similar septal counts have also Montlivaltia cavali Achiardi, 1880, Montlivaltia coaluilensis Wells, 1946 but both differ in the dimensions of the corallite: Montlivaltia cavali has a much smaller diameter and Montlivaltia coaluilensis has a much larger corallite diameter.

Kimmeridgian of the European Boreal (Germany), lower Hauterivian of the Western Atlantic (Mexico) and the European Boreal (France), Barremian of the Central Tethys (Bulgaria), Upper Aptian to Albian of the Eastern Tethys (Iran), Lower Albian of the Western Tethys (Spain).	en	Löser, Hannes, Wetzel, Andreas, Hostettler, Bernhard (2024): Callovian corals from the Swiss Jura.

Septa in cross section externally slightly thicker, becoming slightly thinner towards the centre. No septal symmetry, but size orders can be distinguished. Septal generations differ in length. Approximately half of all septa extend to the calicular centre. Septa of younger generations often connected to the septa of preceding generations. Septal distal margin finely granulated, lateral face with fine thorns, inner margin smooth. Pali absent. All septa of the first generation are attached to the columella. Costae present, confluent. Occasional synapticulae present, mainly in the space between corallites. Columella styliform. Endotheca consists of numerous dissepiments. Wall absent.
