Suberitidae Schmidt 1870
No full textFamilySUBERITIDAE Schmidt <p> <i>Diagnosis (emended)</i></p> <p>Massive, pedunculate or cup-shaped Hadromerida, frequently with membranous raised oscules, texture corky or waxy to the touch, typically displaying a range of coloration from cream to yellow, bright orange or red, frequently also green and blue. Megascleres are tylostyles and subtylostyles in two to three size categories, strongyloxea in one to two size categories, and occasionally oxea which may be centrotylote. Microscleres are absent. Megasclere architecture usually semi-radial with loosely structured anastomosing loose tracts of megascleres, almost always radial at the sponge surface where the ectosome is raised in vertical to fanning brushes of small megascleres, or strictly radiating from the base of the sponge. Reproduction is oviparous, some species gemmulate, one genus forms an association with hermit crabs.</p>Published as part of <i>McCormack, Grace P. & Kelly, Michelle, 2002, New indications of the phylogenetic a nity of Spongosorites suberitoides Diaz et al., 1993 (Porifera, Demospongiae) as revealed by 28 S ribosomal DNA, pp. 1009-1021 in Journal of Natural History 36 (9)</i> on page 1018, DOI: 10.1080/00222930110040394, <a href="http://zenodo.org/record/5301224">http://zenodo.org/record/5301224</a>

Finally, we urge caution in proposing changes to the taxonomic classi cation of the Halichondrida with respect to the Hadromerida (see Chombard and Boury-Esnault, 1999). Considerably more sequence data from 28S rRNA and possibly 18S rRNA genes is required, from a greater range of representative taxa, before a nal picture of the groups as a whole emerge.</p>Published as part of <i>McCormack, Grace P. & Kelly, Michelle, 2002, New indications of the phylogenetic a nity of Spongosorites suberitoides Diaz et al., 1993 (Porifera, Demospongiae) as revealed by 28 S ribosomal DNA, pp. 1009-1021 in Journal of Natural History 36 (9)</i> on page 1019, DOI: 10.1080/00222930110040394, <a href="http://zenodo.org/record/5301224">http://zenodo.org/record/5301224</a>
Adontorhina Berry 1947
No full textGenus Adontorhina Berry, 1947 Type species: Adontorhina cyclia Berry, 1947 Description. Shell small, fragile, compressed to orbicular; surface sculpture of smooth commarginal striae, radial sulcus reduced or lacking. Beaks prosogyrous, low on the dorsal margin. Periostracum thin, lightly straw coloured. Ligament mostly internal, set on a narrow sunken shelf posterior to the beaks. Hinge plate composed of two sections, both anterior and posterior to the beaks; without true teeth but with irregular granules varying between species from weakly to strongly expressed. All possess a single demibranch. Foot with heel, lateral pouches relatively small and undivided. Surface of lateral pouches has the appearance of arborescent tufts. Remarks. The irregular granules on the hinge margin have only been reported in this genus. Indeed, when first discovered Berry (1947) recorded “I have been unable to find any described genus or species to which it can be referred”, owing to the uniqueness of the granular hinge. A large majority of the shells in the Thyasiridae have either edentulous hinges or underdeveloped tubercles instead of teeth (Payne & Allen, 1991). Coan et al. (2000) separated the externally similar Adontorhina from Leptaxinus Verrill & Bush, 1898, on the basis of the distinctive hinge. Scott (1986) remarked that there is wide variation in strength of expression of the irregular granules across the genus. While the granules on the hinge plate is the strongest character uniting the species of Adontorhina, all have a reduced sulcus, low umbones and the lateral pouches are undivided and not thrown into numerous lobes. The foot of each species is noticeably shortened with a deep sagittal groove.Published as part of Barry, Peter J. & Mccormack, Grace P., 2007, Two new species of Adontorhina Berry, 1947 (Bivalvia: Thyasiridae) from the Porcupine Bank, off the west coast of Ireland, pp. 37-49 in Zootaxa 1526 on pages 38-39, DOI: 10.5281/zenodo.17753
Monopseudocuma McCarthy and Gerken 2006, gen. nov.
No full textMonopseudocuma McCarthy and Gerken, gen. nov. Diagnosis: The genus Monopseudocuma gen. nov. can be distinguished from all others by the combination of 1 pair of pleopods in the male, and the normal structure of pereopod 1. There are fully developed exopods on pereopods 1–4 in the male, and on pereopods 1–2 in the female. There are biarticulate rudimentary exopods on pereopods 3–4 in the female. The female antenna 2 is uniarticulate. The uropods are long and slender. Type species: Monopseudocuma gilsoni, by monotypy. Etymology: The genus is named Monopseudocuma because of the single pair of pleopods in the male and overall similarity to the genus Pseudocuma G.O. Sars. Remarks: Monopseudocuma is similar to Pseudocuma in overall form, carapace morphology, the exopods on the pereopods and the uniarticulate antenna 2 in the female. Pseudocuma differs in having 2 pairs of pleopods in the male, the second of which is rudimentary. The only other pseudocumatid which possesses a single pair of pleopods in the male is Petalosarsia longirostris Jones, 1973, and the new genus can be differentiated from Petalosarsia Stebbing 1893 by its slender, nonchelate first pereopod.Published as part of Mccarthy, Alison M., Gerken, Sarah, Mcgrath, David & Mccormack, Grace P., 2006, Monopseudocuma a new genus from the North East Atlantic and redescription of Pseudocuma gilsoni B | cescu, 1950 (Cumacea: Pseudocumatidae), pp. 39-56 in Zootaxa 1203 (1) on page 42, DOI: 10.11646/zootaxa.1203.1.2, http://zenodo.org/record/506436
