A re-evaluation of original descriptions vs. old and new materials allow us to consider Darwinella simplex Topsent, 1892 a valid species. The validity of Darwinella simplex solves the extremely disjunct Australian-Mediterranean geographic pattern and matches the hypothesis of a species complex.</p></div>	https://treatment.plazi.org/id/CFD2C9B20A88EF2E8EB896CD1B9F746A	Public Domain	No known copyright restrictions apply.

As for the taxonomic status Pleraplysilla minchini is regarded by Vacelet (1959) as a synonym of Pleraplysilla spinifera . Later authors, as Cabioch (1968) and Borojevic et al. (1968), considered both species as valid. The material available for our study seems to confirm a specific divergence between the two. Pleraplysilla spinifera is generally recognizable at sight by the very pronounced, spaced conules. Its fibres reach a length of 12 mm, with a thickness of 450 µm near the base; they are generally branched; sometimes more than one fibre starts from a common basal plate; the inclusions are mostly closely-packed sand grains. In Pleraplysilla minchini the fibres are less widely spaced, they reach not more than 3 mm in length and a diameter of 160 µm near the base; they are generally not branched and there is a prevalence of sponge spicules in their inclusions.</p></div>	https://treatment.plazi.org/id/C8ADD98A70821E3C179F7386A59A2194	Public Domain	No known copyright restrictions apply.

Schmidt collection, from Lesina (Adriatic Sea), and other specimens belonging to the Schmidt’s collection preserved in the same museum. The study in depth of this dry holotype material resulted in the evidence that it does not belong to the genus Ircinia but perfectly matches the genus Sarcotragus . The holotype is, probably, a fragment of a bigger specimen and does not exceed 15 cm in diameter; no traces of dermal membrane or choanosomal architecture are visible, suggesting that it can be a beached specimen. The type material of Pallas Spongia fasciculata is missing and the single specimen of Ircinia fasciculata belonging to the Schmidt’s collection (NHMG 15499) must be ascribed to the genus Sarcotragus . Pronzato et al. (2004) investigated the species formerly named Ircinia fasciculata (Pallas, 1766); the result was that Ircinia variabilis (Schmidt, 1862) became the type species of the genus Ircinia Nardo, 1833 and the specimen LMJG 15499, of Ircinia fasciculata, was moved under the genus Sarcotragus Schmidt, 1862 affirming that: "a further study will decide if this species is a good one or a synonym". Pronzato et al. (2004) focused the problematic status of the taxon but did not describe the species. Here a new combination for Sarcotragus fasciculatus is proposed. Sarcotragus fasciculatus is clearly different from the other species ascribed in the genus, also when compared with extra-Mediterranean species (Pronzato et al. 2004) because all its fibres are free of inclusions and primary ones are formed by "fascicules of secondaries".</p></div>	https://treatment.plazi.org/id/2105EB40E7E191711DC3CD79CA3E18E3	Public Domain	No known copyright restrictions apply.

Moreover many authors, in various papers, described this species differently, contributing to determine its problematic taxonomic status. In contrast with that, the commercial “Zimoccas” really belong to a species distinctly different from the other specieshitherto ascribed tothe genus Spongia as reported also by Schmidt (1862), Schulze (1879a) and de Laubenfels (1948). As a consequence the Graz Museum type needs to be carefully studied. The present description is based on the specimens TRG Ker 346, DTRG Ker 347, Jerba-El-Jem (Tunisia), 3-4 m, soft bottom, August 2006. Many traders consider “Zimocca” as the best commercial Mediterranean sponge.</p></div>	https://treatment.plazi.org/id/0CEF2E533EF90F65264ACB7765DBA546	Public Domain	No known copyright restrictions apply.

Indeed the comparative analysis of diagnostic traits of Scalarispongia vs. Cacospongia Schmidt, 1862 clearly indicates that no diverging morphological characters exist among them except for the ladder-like arrangement of skeletal polygonal meshes that in some species, i.e. Cacospongia scalaris, are mostly but not always rectangular. Rectangular meshes are displayed less frequently also in other species of Mediterranean cacospongias. We consider the trait 'skeleton ladder-like with rectangular meshes’ not diagnostic at the genus level in agreement with Schmidt (1862), Vacelet (1959), Pulitzer-Finali and Pronzato (1976) and Pronzato and Manconi (2011). Moreover molecular data (see Borchiellini et al. 2004) indicate that C. scalaris belongs to the genus Cacospongia . Cacospongia proficens and Cacospongia scalaris belong therefore to the genus Cacospongia .</p></div>	https://treatment.plazi.org/id/C1839493D4511168E6E3F2E1183CD6F2	Public Domain	No known copyright restrictions apply.
