Distribution and diversity of the Opheliidae (Annelida,Polychaeta) on the continental shelf and slope of Iceland,with a review of the genus <Emphasis Type="Italic">Ophelina</Emphasis> in northeast Atlantic waters and description of two new species

The diversity, taxonomy and distribution of the Opheliidae (Annelida: Polychaeta) in Icelandic waters is reviewed based on material collected during the BIOICE project. Nine opheliid species are recorded from Iceland; of these, three were previously reported in the area (Ophelia limacina, Ophelina cylindricaudata and O. acuminata), four are new for Icelandic waters (Ammotrypanella cf. arctica, Ophelina abranchiata, O. helgolandica and Tachytrypane jeffreisii), and two are new to science. Ophelina basicirra sp. nov. is distinguished by having a narrow anal tube with one short proximal anal cirrus in ventral position. Ophelina bowitzi sp. nov. is characterized by the small size of its anterior branchiae, which become larger in the middle and posterior body regions, and by an upwardly bent anal tube that is wide at the base and narrowing distally. The genera Euzonus, Armandia and Polyophthalmus are not represented in the BIOICE samples. The distribution of each species off Iceland is presented; one species is restricted to shallow waters of northwestern fjords, three species are found south of the GIF Ridge, and five species are circumicelandic. Several body characters with taxonomic relevance in some species are reviewed based on SEM images. Furthermore, as a first step towards a future revision of the genus Ophelina Örsted 1843 in North Atlantic waters, the status of each species originally described or subsequently reported from the area is commented on, and a key to the currently valid species is presented. Ophelina longicephala Hartmann-Schröder, 1977, formerly a subspecies of O. delapidans (Kinberg, 1866), is raised to species status.     

Additions to the Mysid Fauna (Crustacea: Mysidacea) from Coastal Waters of Oman, Including Descriptions of Two New Species

Two new species of mysid shrimps are described from shallow coastal waters of Northern Oman. Haplostylus quadrispinosus sp. nov. is primarily distinguished from allied species by the arrangement and size of lateral spines on the telson. The form of the telson and exopod of the 4th male pleopod characterize a second new species, Anisomysis arabica sp. nov. A third species Mysidopsis kenyana, was previously recorded only from East Africa and its presence in samples considerably extends its geographical distribution. Four mysid species are now documented from coastal waters of Oman.     

Three new species of genus Myrmica (Hymenoptera: Formicidae) from Himalaya

Three new species of the genus Myrmica are described from the Himalayas. Myrmica curvispinosa sp. nov., Myrmica kothiensis sp. nov. and Myrmica religiosa sp. nov. belong to the Myrmica inezae species group, which is earlier represented by 4 species. Myrmica curvispinosa sp. nov. is described based on worker and gyne, with a report of ergatoid as well. Myrmica kothiensis sp. nov. and Myrmica religiosa sp. nov. are described based on worker caste only. A key to the species of the Myrmica inezae species group has been provided in the following.     

A Revision of Australian River Prawns, Macrobrachium (Crustacea: Decapoda: Palaemonidae)

A taxonomic revision of Australian Macrobrachium identified three species new to the Australian fauna – two undescribed species and one new record, viz. M. auratumsp. nov., M. koombooloombasp. nov., and M. mammillodactylus(Thallwitz, 1892). Eight taxa previously described by Riek (1951) are recognised as new junior subjective synonyms, viz. M. adscitum adscitum, M. atactum atactum, M. atactum ischnomorphum, M. atactum sobrinum, M. australiense crassum, M. australiense cristatum, M. australiense eupharum of M. australienseHolthuis, 1950, and M. glypticumof M. handschiniRoux, 1933. Apart from an erroneous type locality for a junior subjective synonym, there were no records to confirm the presence of M. australe(Guérin-Méneville, 1838) on the Australian continent. In total, 13 species of Macrobrachiumare recorded from the Australian continent. Keys to male developmental stages and Australian species are provided. A revised diagnosis is given for the genus. A list of 31 atypical species which do not appear to be based on fully developed males or which require re-evaluation of their generic status is provided. Terminology applied to spines and setae is revised.     

Additions to the mysid fauna (Crustacea: Mysidacea) from coastal waters of Mozambique, with descriptions of two new species

Sampling for mysid shrimps in shallow coastal waters of Mozambique provided new distribution records for Siriella brevicaudata Paulson, 1875, Gastrosaccus bispinosa Wooldridge, 1978, Gastrosaccus longifissura Wooldridge, 1978, Dioptromysis proxima Nouvel, 1964 and Anisomysis maris rubri Bãcescu, 1973. Rhopalophthalmus tropicalis sp. nov. and Gastrosaccus mozambicus sp. nov. are described for the first time. The former species is distinguished from its closest relative R. terranatalis O. Tattersall, 1957 by its much smaller size, the lack of serrations on the lateral spines of the telson, the structure and arrangement of the spines on the antennal sympod and the number of subdivisions of the propodus of the thoracic endopod. Adult males of G. mozambicus sp. nov. show affinity to G. bispinosa, but the two species are separated by the form of the two distal exopod segments on the 3rd pleopod.     

Hamatopeduncularia Yamaguti, 1953 (Monogenea: Ancylodiscoididae) from catfish off Peninsular Malaysia: Description of two new species and insights on the genus.

Hamatopeduncularia longiangusticirrata sp. nov. and H. petalumvaginata sp. nov. were collected from Arius maculatus and Nemapteryx caelata, respectively from Tanjung Karang, Peninsular Malaysia. Morphological and molecular investigations were carried out to ascertain the identity of the new species. The two new species differ from previously described Hamatopeduncularia species in the morphology of the male and female reproductive organs. Hamatopeduncularia longiangusticirrata sp. nov. possesses a long penis similar to H. elongata, H. longicopulatrix, H. brisbanensis, H. major and H. petalumvaginata sp. nov., but differs in having a thread-like tapering distal end and can be distinguished from H. brisbanensis and H. major in not having an accessory piece. Hamatopeduncularia longiangusticirrata sp. nov. is also unique in having an ornamented penis initial and a vaginal tube surrounded by fine hair-like structures. Hamatopeduncularia petalumvaginata sp. nov. possesses a simple penis without an accessory piece and a petaloid vaginal opening that resembles the arrangement of petals on a flower. Maximum likelihood trees were constructed from partial 28S and 18S rDNA sequences of the two new species and other ancylodiscoidids to reveal a strongly supported monophyletic branch consisting of the two new species for both markers. According to Lim's classification in 1996 of Hamatopeduncularia species penis type, H. petalumvaginata sp. nov. has been classified within the elegans-type and H. longiangusticirrata sp. nov. is proposed as the longiangusticirrata-type.     

Two new species of cicadas from Vietnam (Hemiptera: Cicadoidea: Cicadidae)

Two species of Vietnamese cicadas are described as new. Pomponia daklakensis sp. nov. is described from Daklak Province and Haphsa bicolora sp. nov. is described from Gai Lai Province. Pomponia daklakensis has become a pest of coffee in Vietnam.     

Polychaete species captured in sediment traps moored in northwestern Mediterranean submarine canyons

Sediment traps were placed in the water column both inside and in the vicinity of three northwestern Mediterranean submarine canyons. The sediment traps with 12 rotary collectors were deployed on mooring lines 30 and 500 m above the sea floor, and were sampled fortnightly. Polychaete worms (Anelida) and hydromedusae (Cnidaria) were the most abundant zoological taxa captured. Whereas hydromedusae and three of the polychaete species were clearly planktonic organisms, 16 polychaete species were adult benthic forms without special adaptations for swimming, and sometimes also had a large biomass. Four of the 19 polychaete species are described as new species: Aricidea (Allia) longisetosa sp. nov. , Paradoneis hirsuta sp. nov. , Ophelina margaleffi sp. nov. , and Exogone (Parexogone) canyonincolae sp. nov. The rich collection of polychaetes obtained leads us to postulate that these animals are supported by a continuous flux of organic matter, and that they are adapted to the rigorous physical conditions that may occur between the seafloor and the bottom water. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 155 , 1–21.     

Lecithoceridae (Lepidoptera: Gelechioidea) of New Guinea: Part II. Hamatina gen. nov., with descriptions of four new species

This is the second part in a series of taxonomic studies on the family Lecithoceridae (Lepidoptera: Gelechioidea) of New Guinea. A new genus, Hamatina gen. nov., is described, based on the type species, H. hemitoma (Diakonoff), comb. nov., and four new species are described: H. nabangae sp. nov., H. robdevosi sp. nov., H. jembatana sp. nov., and. iriana sp. nov. A key to four allied genera is given. Adults, heads, labial palpi, wing venations, and the male genitalia are illustrated.     

Kimmeridgian-Volgian Aporrhaidae (Stromboidea: Gastropoda) of the Russian Platform

Kimmeridgian-Volgian Aporrhaidae from European Russia are described for the first time. They are referred to three genera, including two new genera, Undoriptera gen. nov. and Volgacheilus gen. nov. with three new species, Undoriptera tridactylus sp. nov., Volgacheilus rogovi sp. nov., and Dicroloma tenuistriata sp. nov.     

First description of an euryoecious acanthoecid choanoflagellate species,Enibas tolerabilis gen. et sp. nov. from a salar in the Chilean Andes based on morphological and transcriptomic data

In general, acanthoecid choanoflagellates have been described to occur exclusively in brackish water to marine habitats. Only recently, two studies have proven their existence in inland waters. One of them has shown, that an acanthoecid species from a small lake (near Apia on the island of Upolu, Samoa) is strictly freshwater adapted, not able to tolerate even brackish water. In this study, we present the first euryoecious acanthoecid species, able to live and reproduce in freshwater as well as under hypersaline conditions. The new species, Enibas tolerabilis gen. et sp. nov. was isolated in 2017 from the Salar de Ascotán in the Altiplano at 3750 m a. s. l., Northern Chile. The salinity at the time of sampling was 6 PSU. A series of autecological experiments have revealed a salinity tolerance from freshwater up to 70 PSU. In our phylogenetic analysis, E. tolerabilis gen. et sp. nov. clustered within the family of Acanthoecidae, forming a well-supported sister clade together with two other, environmental choanoflagellate sequences. We erected a new genus, Enibas gen. nov. and described the morphology, molecular biology and autecology for E. tolerabilis gen. et sp. nov. which has a stephanoecid-like lorica morphology. We emphasize that the definition of the genus Stephanoeca, being polyphyletic, is in urgent need of revision as we showed that this morphology is present in both acanthoecid families.     

Taxonomic review of the genus Eupoecilia Stephens (Lepidoptera: Tortricidae: Tortricinae) in Korea with descriptions of two new species

Eupoecilia Stephens (Lepidoptera: Tortricoidea: Tortricidae) comprises 39 described species worldwide. Eight species of the genus are recognized from Korea, two of which, Eupoecilia curvifasciata sp. nov. and E. koreana sp. nov., are described as new. Also, Eupoecilia sanguisorbana (Herrich-Schäffer, 1856) is reported for the first time from Korea. All the known species are described or redescribed, and the adults and genitalic structures are illustrated. In addition, a key to the Korean species is also provided.     

Sinharaja gen. n., a new Uropodina mite genus from Sri Lanka with description of two new species (Acari: Mesostigmata: Uropodidae)

A new Uropodina genus (Sinharaja gen. n.) is described on the basis of two new species (S. ceylonensis sp. n. and S. sinhala sp. n.) from Sri Lanka. The new genus differs by the strongly sclerotised dorsal lines, pentagonal pygidial shield, the shape and length of dorsal setae and the shape of first and fourth hypstomal setae, internal malae and epistome from the other known Uropodina genera.     

Integrative Taxonomy and Species Delimitation in Harvestmen: A Revision of the Western North American Genus Sclerobunus (Opiliones: Laniatores: Travunioidea)

Alpha taxonomy, and specifically the delimitation of species, is becoming increasingly objective and integrative. The use of coalescent-based methods applied to genetic data is providing new tools for the discovery and delimitation of species. Here, we use an integrative approach via a combination of discovery-based multivariate morphological analyses to detect potential new species. These potential species are then used as a priori species in hypothesis-driven validation analyses with genetic data. This research focuses on the harvestmen genus Sclerobunus found throughout the mountainous regions of western North America. Based on our analyses, we conduct a revision of Sclerobunus resulting in synonymy of Cyptobunus with Sclerobunus including transfer of S. cavicolens comb. nov. and elevation of both subspecies of S. ungulatus: S. ungulatus comb. nov. and S. madhousensis comb. nov., stat. nov. The three subspecies of S. robustus are elevated, S. robustus, S. glorietus stat. nov., and S. idahoensis stat. nov. Additionally, five new species of Sclerobunus are described from New Mexico and Colorado, including S. jemez sp. nov., S. klomax sp. nov., S. skywalkeri sp. nov., S. speoventus sp. nov., and S. steinmanni sp. nov. Several of the newly described species are single-cave endemics, and our findings suggest that further exploration of western North American cave habitats will likely yield additional new species.     

Xenophyophores (Rhizaria,Foraminifera), including four new species and two new genera,from the western Clarion-Clipperton Zone (abyssal equatorial Pacific)

The Clarion-Clipperton Zone (CCZ) occupies a vast swathe of the Pacific with extensive polymetallic nodule deposits. Eastern and central parts host diverse assemblages of xenophyophores (megafaunal agglutinated foraminifera). Here we describe xenophyophores obtained using a Remotely Operated Vehicle from the western CCZ. Eleven distinct forms include two known species, Stannophyllum zonarium Haeckel, 1888 and Aschemonella monile Gooday and Holzmann in Gooday et al., 2017b. Another four are described as new species based on morphological and genetic data. In Abyssalia foliformis gen. nov., sp. nov. and Abyssalia sphaerica sp. nov. the flattened or spherical test comprises a homogeneous framework of sponge spicules. Psammina tenuis sp. nov. has a delicate, thin, plate-like test. Moanammina semicircularis gen. nov., sp. nov. has a stalked, fan-shaped test and is genetically identical to ‘Galatheammina sp. 6’ of Gooday and co-workers from the eastern CCZ. Sequence data revealed a spherical ‘mudball’, which disintegrated and cannot be formally described, to be a novel xenophyophore. Finally, four morphospecies are represented by dead tests: Psammina spp., Reticulammina sp., and an unknown genus with a unique test structure. This collection enhances our knowledge of Pacific xenophyophore diversity and provides the first genetic confirmation of wide geographic ranges for abyssal species.     

Two new species of Antispila Hübner (Lepidoptera: Adeloidea: Heliozelidae) associated with Hydrangea (Hydrangeaceae) from China

The genus Antispila Hübner, [1825] is poorly recorded from China. Two new Antispila species, A. longcangensis, sp. nov. and A. emeishanensis, sp. nov. feeding on Hydrangeaceae, are described from Sichuan, China. The adult male and female, genitalia and venation of both species are illustrated. Diagnostic characters of these species are compared with other described Antispila species from China. DNA barcodes sequences of the two new species are also provided.     

Taxonomy of the genus Ectopioglossa Perkins from China,with two new species and an updated key to the Oriental species (Hymenoptera: Vespidae: Eumeninae)

A total of five species of the genus Ectopioglossa is reviewed from China, of which two new species are described and illustrated. These two new species are Ectopioglossa trimacula sp. nov. and E. convexa sp. nov., collected from Guangxi and Yunnan, China, respectively. Among other three nomial species, E. sublaevis (Smith, 1857) is new to China. An updated key to the Oriental species is also provided.     

New bibionomorpha (Insecta: Diptera) from the Jurassic of Asia

The new species Protorhyphus rohdendorfi sp. nov. (Protorhyphidae), Mesorhyphus handlirschi sp. nov., and M. hennigi sp. nov. (Anisopodidae), Procramptonomyia ponomarenkoi sp. nov. and P. kovalevi sp. nov. (Procramptonomyiidae) are described from the Upper Jurassic deposits of Mongolia (Shar Teg); some features of Archirhyphus asiaticus Rohdendorf, 1964 are revealed. The latter two species are also known from the locality of Karatau (Kazakhstan, J_2/3). The genus Tega Blagoderov, Krzemi??ska, and Krzemi??ski, 1993 is transferred from the family Cramptonomyiidae into Anisopodidae (Teginae subfam. nov.).
