Three New Species

The genus Xyrodromeus Lugo-Ortiz & McCafferty was established for Afrotropical species of Baetidae (Ephemeroptera) possessing bladelike mandibles. Recently, three new species were described from Madagascar. Xyrodromeus ambiguus n. sp. is established for larvae collected in the North and North-East of Madagascar. It possesses most of the generic features of Xyrodromeus, but differs significantly from all the previously known species by possessing two rows of denticles on the tarsal claws. This species has an intermediate position between Xyrodromeus and Dicentroptilum Wuillot & Gillies. While it may confirm the strong relationship between the two genera, it also opens the question of their validity and could suggest that all these species belong to a single variable and graded genus.

Three New Species

Most specimens of carnivorous sponges (Demospongiae, Poecilosclerida, Cladorhizidae) collected in the deep Pacific are usually found to be undescribed taxa. New Zealand’s EEZ, containing Kermadec Trench and Volcanic Arc to the north, Chatham Rise to the southeast, and parts of Macquarie Ridge to the southwest of New Zealand, as well as parts of Australia’s EEZ surrounding Macquarie Island, on Macquarie Ridge, have produced high numbers of new species and possibly new genera, and these are presently being described. In this work, we describe three new species of Cladorhizidae, each remarkable for the ‘exceptions to the rule’ that they represent. Abyssocladia carcharias sp. nov., from Monowai Seamount on the Kermadec Volcanic Arc, has the shape of a pedunculate disc with radiating filaments, and is characterized by three types of unique multidentate isochelae. Asbestopluma (Asbestopluma) anisoplacochela sp. nov., from the southern most end of the Three Kings Ridge, is erect and cylindrical with lateral expansions. In addition to the usual Asbestopluma microscleres, this species displays a new form of microsclere, termed ‘anisoplacochelae’. These unprecedented microscleres bear a plate-like central tooth similar to that of the placochelae of Guitarridae, but the ends are dissimilar in shape and dimensions. Asbestopluma (Asbestopluma) desmophora sp. nov., from Cavalli Seamounts off the north east coast of New Zealand, Hikurangi Plateau to the east of the North Island, and the Chatham Rise extending east from the South Island (all New Zealand EEZ), and on Macquarie Ridge (Australia EEZ), is an erect dichotomously branching sponge, that has desma megascleres densely packed into the enlarged base of attachment. Implications for the phylogeny of these three unusual species are considered.

Three New Species

The presence of cryptic species is fairly frequent in many invertebrate groups and even more so among invertebrates with simple morphology, such as nemerteans. Consequently, the use of molecular methods for species delimitation has become a needed tool to complement morphological analyses to better recognise such species. Nemertopsis bivittata is one example of species with subtle morphological variation, but ample geographic distribution, being a good candidate for a species complex study. Here we applied two mitochondrial genes, and 2903 single nucleotide polymorphism (SNP) variants in addition to morphological characters to investigate the presence of cryptic species among specimens previously identified as N. bivittata along the Brazilian Coast. To do so, specimens were collected at 15 different sites in the north-east, south-east and southern regions. Three new species of Nemertopsis are described based on morphological and molecular analyses: Nemertopsis caete sp. nov., Nemertopsis pamelaroeae sp. nov. and Nemertopsis berthalutzae sp. nov. The species N. pamelaroeae and N. berthalutzae present broad distributions from north-east to south-east; N. caete, however, is restricted to the north-east coast. This is the first study to use this combined approach in nemerteans and shows the advantages of integrating genomic markers with classical taxonomy, and applying objective approaches to delimiting species as independently evolving entities.

Some 2,000 Ptiliidae collected in the North and South Islands of New Zealand in 1983/1984 by Peter Hammond of the Natural History Museum, London, are determined to 34 species, four of which are new to the country. As there are very few previous records, most from the Auckland district of North Island, the Hammond collection provides much new distributional data. The three new species: Nellosana insperatus sp. n., Notoptenidium flavum sp. n., and Notoptenidium johnsoni sp. n., are described and figured; the genus Ptiliodes is moved from Acrotrichinae to Ptiliinae, and Ptenidium formicetorum Kraatz recorded as a new introduction. Information is provided to aid separation of the new species from those previously recorded.

The littoral morphology of the Bermudas is an erosional morphology in limestones, the main processes being mechanical action and solution. The temperatures, in January and February, of the waters washing the Bermudas, are low enough to prevent the growing of true coral reefs. Therefore, it is not the morphology of a coral reef. The predominance of wave-cut cliffs is the most striking feature, despite the low and gently rolling topography. There are, however, other types of coasts on the islands, the mangrove being found on many sheltered shores. The writer thus opposes the sheltered shores of the sounds to the ones exposed on the southcoast, while the shores of the north and north-east coasts belong to an intermediate type. The steplike arrangement of the coastal forms of solution of the Bermudas limestones is primarily linked to the amount of the tidal range. These features are similar to those described on the shores of the warm seas, where the tide is negligible or weak. The Bermudas occupy an intermediate position between the regions where reefs are built by corals, and those, to the north, where solution, helped by other processes, occurs without compensation.

Pangrapta Hübner, 1818 was erected for the North American species P. decoralis Hübner, 1818 as its type species. The genus Pangrapta presently consists of about 100 species, and is widely distributed in China and surrounding regions, as well as in the New World (Hu & Wang, 2013). In this article, three new species, P. nanlingensis sp. n., P. jianfenglingensis sp. n. and P. hainanensis sp. n., are described from China. Each of them is superficially similar to the species, P. neorecusata (Hu & Wang, 2013), P. perturbans (Walker, 1858) and P. pannosoides (Holloway, 2005), correspondently. The known Southeast Asian species, P. shivula (Guenée, 1852), is reported for the first time from China. Adults and genitalia are illustrated. The type series of all described species (including holotypes) are deposited in Southwest University of Science and Technology (SWUST), Mianyang, China.

Three new Ophryotrocha species are described from sites with high levels of organic carbon flux including a whale-fall at 125 m depth off the Swedish coast and sediment sampled at 104 m depth beneath a fish farm in a Norwegian fjord. Phylogenetic analyses based on the nuclear gene H3 and the mitochondrial genes COI and 16S using MrBayes and Maximum Likelihood analyses show that Ophryotrocha eutrophila sp. nov. is a close relative to Ophryotrocha puerilis, while Ophryotrocha craigsmithi sp. nov. falls together with Palpiphitime lobifera, and Ophryotrocha scutellus sp. nov. occur within the 'hartmanni' clade. The genus Ophryotrocha is in our study monophyletic only if the genera Iphitime and Palpiphitime are included. Two representatives of Ophryotrocha previously described from anthropogenically-enriched sediments are here reported for the first time in very high abundance from a naturally occurring habitat. We suggest that whale falls are important habitats for the evolution of ecosystem services such as the degradation of complex organic compounds.

AbstractAntechiniella septentrionalis n. sp. (Spirurida: Acuariidae) is described from the duodenum of a tundra vole, Microtus oeconomus (Pallas), collected in the Magadan region in the north-east part of Russia. It differs from A. suffodiax (Beveridge & Barker, 1975) and A. sertatum Smales, 1991 mainly in having a larger number of postcloacal papillae (5–6 pairs vs 4 pairs), a differently shaped left spicule, the disposition of precloacal papillae in two rows vs one, and oblong vs oval eggs. Other differences include the different disposition of ovaries in A. septentrionalis n. sp and A. suffodiax and the different structure of deirids in A. septentrionalis n. sp. and A. sertatum. The new species was characterized molecularly (partial sequences for 18S rRNA, 28S rRNA and cox1 mtDNA). The phylogenetic analyses performed showed the affinity of the new species to the members of the Acuariidae and other spirurid nematodes.
