Genus Clathrina Gray, 1867 sensu Klautau et al. 2013

Remarks. The species of the former large genus Clathrina have been subdivided by Klautau et al. 2013 into distinct genera. The restricted genus Clathrina unites the species with asconoid tubuli anastomosed into loosely organized or more tightly anastomosed cormi with spiculation consisting exclusively of small triactines. We obtained a considerable number of partial 28SrRNA sequences to assist us in classifying the collected members of this still very large genus. We combined our sequences with our Indonesian, Oliver Voigt’s (2017), Sponge Barcode Project and GenBank Clathrina sequences in an analysis the results of which are given in the phylogenetic tree of Fig. 2A . See above for further comments on the results.

FIGURE 2. Maximum-likelihood tree based on analysis of sequences of the partial 28S gene (C2–D2 region, comprising 442 sites) of Western Indian Ocean Calcinea newly generated by the Naturalis Biodiversity Center and sequences additionally obtained from GenBank, the Sponge Barcode Project and from Oliver Voigt (München) from the Red Sea, Indonesia, Australia, and a few sequences from other parts of the world, to demonstrate the affiliation of the compared species. Please note that Arturia sequences do not appear in the same clade, indicating Arturia is non-monophyletic. Numbers at the root of clades are bootstrap values of 1000 replicates. Since the high number of sequences were difficult to read in detail, we subdivided the present tree in three detailed sections 2A, 2B, and 2C.
