Three New Species

A consultation of the original descriptions of the genera of Scissurellidae led the author to conclude that the valid names for the genera of this family are: Scissurella d'Orbigny, 1823 (redescription by Sowerby, 1824), Anatoma Woodward, 1859, Inoisura Hedley, 1904, Scissurona Iredale, 1924, Sinezona Finlay, 1927. Scissurella and Anatoma are cosmopolites, the first generally living in shallow waters, associated to sea-weeds, while the second is found in deep waters. The three last genera are restricted to Australasia. Three new species are described from the Brazilian coast: Soissu rella alexandrei, Scissurella eleotilis and Scissurella morretesi. The internal anatomy of S. alexandrei is described. These three new species have been found in littoral shallow waters, the two first on the northeast Brazilian coast, the third on the coast of the State of São Paulo. The fourth known species of Scissurellidae from Brazil, Anatoma aedonia (Watson, 1886), was dredged by H.M.S, "Challenger", in 1873, off Pernambuco, 350 fm (640 m).

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

Three New Species

Three annual Diascia species are described from the western Cape. Two species, D maculata K.E. Steiner and D. humilis K.E. Steiner have small flowers and are closely related.  D. maculata is characterized by a slightly gibbous corolla with no spurs or sacs, erect stamens, and a distinct patch of oil-secreting trichomes in the tube at the base of each upper and lateral corolla lobe. D. humilis is characterized by a bisaccate corolla, forward projecting stamens and oil-secreting trichomes localized in corolla sacs. The third new species,  D hexensis K.E. Steiner, is most similar to D. sacculata Benth.. but it differs from that species by its larger flowers and much longer spurs which curve downward instead of upward.

Recently developed analytical procedures for meshwork fenestrate and pinnate bryozoans made it possible to recognize two Russian species in the Toroweap Formation of southern Nevada. This analysis separates zoarial and zooecial features and emphasizes the three-dimensional form and size of the zooecial chamber as well as accessory features. In this investigation, these analytical procedures are successful even when specimens are fragmented and embedded in a hard rock matrix.The bryozoans in the Toroweap Formation in this study were found to be more similar to Permian species of the Russian platform than to species described in earlier North American Permian studies. Five species of fenestrate bryozoans are present in the Toroweap Formation. Wjatkella permiana Morozova, 1970, and Polypora sargaensis Trizna, 1948, originally described in Russia, are recognized in the Toroweap. Three new species, Penniretepora oppositus n. sp., Septopora bilateralis n. sp., and Reteporidra anaphora n. sp., are present and, along with the Russian species, are described in this paper.The local range zones of the five species of fenestrates were identified in three measured sections. Penniretepora oppositus and Septopora bilateralis are present throughout the three sections; Reteporidra anaphora is present in the lower two-thirds of the three sections; Wjatkella permiana is present in the middle parts of the three sections; and Polypora sargaensis is present in the upper parts of the three sections. Concurrent range zones, based on ramose bryozoans, were previously identified in two of the three sections and, using the distribution of the fenestrates in these two sections, four of the five concurrent range zones were recognized in the third section.

We describe three new gecko species of the Paroedura oviceps clade, diagnosed by deep divergences in mitochondrial DNA, absence of haplotype sharing in two nuclear genes (sacs and kiaa1239), and morphological differences. Paroedura spelaea sp. nov. is an extremely slender species from karst habitats in the limestone massif of the Tsingy de Bemaraha National Park in western Madagascar, morphologically reminiscent of P. homalorhina but distinguished by the absence of distinct dorsal rows of spiny tubercles. Paroedura fasciata sp. nov. from the small karstic island Nosy Hara in northern Madagascar is phylogenetically placed sister to P. spelaea despite radical morphological differences. It is morphologically most similar to P. hordiesi from the geographically close Montagne des Français massif, but is smaller, has slightly more spiny dorsal scales, and a distinctive colour pattern with light grey dorsal crossbands. The third species, Paroedura kloki sp. nov., is known from Ankarafantsika National Park and the western slopes of Makira, two sites of dry to transitional forest in western Madagascar. It is at least partly arboreal and morphologically very similar to P. oviceps, from which it differs by spiny scales extending over its entire tail. Although incomplete, the available phylogenetic evidence suggests that the karst specialists in the P. oviceps clade (P. fasciata, P. homalorhina, P. hordiesi, P. spelaea) form a monophyletic group which might have diversified by vicariance after becoming isolated, respectively, in their limestone habitats in Tsingy de Bemaraha, Ankarana, Nosy Hara and Montagne des Français.

Three New Species

Seven species of eukalyptorhynch flatworms from the Galapagos Islands are reported. Six of them belong to the taxon Koinocystididae Meixner, 1924, three of which are new to science. Two of these new species can be attributed to the genus Itaipusa Marcus, 1949 based on the construction of the prostate vesicle and the general structure of the female system. Itaipusa biglandula n. sp. is characterised by a very short, muscular, unarmed penis papilla, whereas I. renei n. sp. is characterised by the presence of a cirrus armed with minute scales, and two large, blunt hooks in the male atrium. The third new species cannot be placed in any existing taxon and therefore a new genus is erected: Galapagetula annikae n. gen. n. sp.. It is characterised by a straight and rather long cirrus, armed with small spines, and a clearly bipartite bursa in the female system. Additional morphological information is given for the three known species of Koinocystididae: I. divae Marcus, 1949; I. variodentata (Karling, Mack-Fira & Dörjes, 1972) Karling, 1978 and Utelga heinckei (Attems, 1897) Karling, 1954. For I. divae a new locality from Curaçao is also mentioned. The seventh species is a species of Gnathorhynchidae: Prognathorhynchus eurytuba Ax & Armonies, 1987, for which new morphological information on the organisation of the genital system is given.

Three new species of Aloninae cladocera from Central and South Brazil are described. Two of them, Acroperus tupinamba sp. n. and Alona yara sp. n., were previously recorded from the area as European taxa Acroperus harpae (Baird, 1834) and Alona quadrangularis (O.F. Müller, 1776), respectively. Acroperus tupinamba differs from the other species of Acroperus in smaller size, long posterior setae of the valves, shorter and wider postabdomen, short setules near the base of postabdominal claw, long apical spines of antenna, and peculiar morphology of limb IV exopodite. Alona yara differs from A. quadrangularis and A. kolweizii Van Damme & Dumont, 2008 in the number of ventral setules on ventral face of limb I, from A. boliviana Sinev et Coronel, 2006 in the shape of the body and postabdomen, narrow labral keel, and absence of projections on epipodites IV–V. The third new species, Celsinotum candango sp.n. differs from all other species of the genus in proportions of postabdomen. It differs from Australian species (C. hypsophilum Frey, 1991, C parooensis Frey, 1991, and C. platamoides Frey, 1991) in a less developed dorsal keel, lateral head pores located close to midline, longer spine on basal segment of antennal exopodite, and in the presence of extremely large projections on exopodites IV–V. Celsinotum candango differs from Brazilian C. laticaudatum Smirnov & Santos-Silva, 1995 in a shorter spine on basal segment of antenna exopodite, in the shape of postabdomen and in morphology of postabdominal denticles. At present, Aloninae fauna of Brazil includes 35 species, and true diversity is undoubtedly higher, with more new species to be expected in the country.

ABSTRACT Tudivasum Rosenberg & Petit, 1987 is a morphologically distinct gastropod genus of low diversity. All but one species are known from Australia and they occur from the intertidal zone down to hundreds of metres on the continental shelf. These carnivorous gastropods are thought to have intracapsular development. The six currently recognized extant species are reviewed here and their geographical ranges clarified. Two new species, Tudivasum chaneyi n. sp. and T. ashmorense n. sp., are described from Ashmore Reef, Western Australia, and are characterized by differences in protoconch colour and shell sculpture. The third new species, T. westrale n. sp., is described from the mid-west coast of Western Australia, where it has long been misidentified as T. spinosum (H. Adams & A. Adams, 1864). We generated a molecular phylogeny based on mitochondrial DNA sequence data to test morphological species concepts and reconstruct relationships among four of the described species. High levels of divergence within one of the new species could indicate an additional cryptic species.
