Recent thecideide brachiopods (Thecideida, Thecideoidea) from northern Sulawesi (Indonesia) with discovery of a new Thecidellina species (Thecidellinidae) Author Simon, Eric Author Lüter, Carsten Author Logan, Alan Author Mottequin, Bernard text Zootaxa 2018 2018-12-03 4526 4 481 515 journal article 27876 10.11646/zootaxa.4526.4.4 65c38733-a538-46c5-a323-af23c50c9adf 1175-5326 2611832 2AEE5959-7D13-4301-B7C8-D8A4D92CC751 Comparison with Thecidellina europa Logan et al ., 2015 In this species, the ventral valve floor has a wider median area between gonad pits that is ornamented with smaller tubercles. The dorsal median septum is thicker, the marsupial orifices are smaller and differently shaped. Canopying spicules are thicker at their base near the valve floor and fuse together producing finely granulate canopies with irregular ventral surfaces covering two-thirds of the brachial cavities ( Logan et al . 2015 , fig. 1L).
