Chewing lice were collected from small shorebirds (Charadriformes: Scolopacidae) overwintering in foraging grounds of coastal Ecuador. On 27 occasions at least one louse (3.7%) was collected from six host species. Based on external morphological characters, at least two species of chewing lice could be preliminary identified (family: Menoponidae), including Actornithophilus umbrinus(Burmeister, 1842) and Austromenopon sp. A. umbrinus was found in the Western Sandpiper (Calidris mauri), Least Sandpiper (C. minutilla), Stilt Sandpiper (C. himantopus), Semipalmated Plover (Charadrius semipalmatus) and Wilson's phalarope (Phalaropus tricolor), whileAustromenopon sp. is presumably the first record collected from the Surfbird (Aphriza virgata). These findings indicate that the distribution of these chewing lice species covers at least the regions around the equator (latitude 0°) until the Arctic in the north, but probably also includes the entire winter distribution area of the host species. This is the first study of chewing lice from Ecuador's mainland coast and more research is required to understand the host-parasite ecology and ectoparasitic infection in shorebirds stopping over the region.

An expanded description of a little-known arctic species Montacuta spitzbergensis from the Sea of Okhotsk with new data on its morphology, ecology and geographical distribution is given. This is the first record of M. spitzbergensis from the north-western Pacific. It differs from other species of Montacuta in its large (to 8.4 mm), elongate–ovate, thick shell with wide, slightly curved hinge plate, wide, short, and shallow resilifer, and weakly developed external ligament. This species occurs in the Arctic Ocean (Spitsbergen, Barents, Kara, Laptev and Chukchi Seas) and the Pacific Ocean (Sea of Okhotsk) at depths from 9 to 232 m at a bottom temperature from −1.62°C to +2.50°C. The hinge structure of the type species of the genera Montacuta and Tellimya is also discussed.

Two new species, Plicatellopsis borealis and Spongosorites beringensis, from the Bering Sea are described; both belong to genera previously not reported from the area. The genus Plicatellopsis, Burton, 1932 (Porifera, Suberitida, Suberitidae) contains five valid species, all recorded from the southern hemisphere. The record of P. borealis n. sp. from the Bering Sea is consequently the first record of the genus from the northern hemisphere. The genus Spongosorites Topsent, 1896 (Porifera, Suberitida, Halichondriidae) contains 22 valid species but none reported from the North Pacific Ocean, Bering Sea or the Arctic Ocean. The geographically closest records are six species occurring in the North Atlantic Ocean. So the description of Spongosorites beringensis n.sp. is the first record of the genus in the region.

Alcataenia campylacantha (Krabbe, 1869) is redescribed and reported for the first time from pigeon guillemots, Cepphus columba Pallas, in Alaska. Specimens of this cestode were also found in black guillemots, Cepphus grylle (Linnaeus) at Point Barrow, Alaska. There were no substantial differences in morphological characters between populations of this cestode from the North Atlantic and North Pacific basins. Additionally, Alcataenia sp. indet. is reported, with a partial description, from Kittlitz's murrelets, Brachyramphus brevirostris (Vigors), in Alaska. This constitutes the first record of dilepidid cestodes from birds of the genus Brachyramphus Brandt.

Taxonomic Studies

Background: Amaranthus is a critical genus from a taxonomic point of view because of its high phenotypic variability, which has led to nomenclatural disorder, misapplication of names, and erroneous species identification. As a whole, floristic and taxonomic studies on this genus are still incomplete. Objectives: The main objective was to record the North American species Amaranthus palmeri in Tunisia for the first time and to point out a second occurrence for Africa. At the same time, we highlight some nomenclatural confusion concerning the name A. palmeri var. glomeratus which appears to be untypified and which should be treated at species rank. Method: The work is based on field surveys, analysis of relevant literature and examination of specimens preserved in the herbaria GH, FI, HFLA, K, MICH, NEBC, NY, MO, P, RO, US, and the Herbarium of Bizerta University. Results: A population of Amaranthus palmeri was discovered in Bizerta Province, representing the first record for the national flora. This record also represents the second record for Africa. Morphological characters, as well as ecological data are provided. Nomenclatural notes are provided for A. palmeri var. glomeratus (lectotype at GH, here designated; isolectotypes at MICH and US), and a new name (A. sonoriensis) is proposed. Conclusion: Amaranthus palmeri is an alien species in Tunisia, growing along roadsides and in public gardens. Future monitoring of the populations found will be necessary to verify possible naturalisation and spreading of A. palmeri in Tunisia. If this happens, actions for eradication of the plants will be necessary.

AbstractParasite diversity above the Arctic circle remains understudied even for commercially valuable host taxa. Thorny skate, Amblyraja radiata, is a common bycatch species with a growing commercial value. Its natural range covers both sides of the North Atlantic including the Arctic zone. Svalbard is a Norwegian archipelago located on the northwest corner of the Barents Shelf which sustains a spectacular species diversity. So far, several monogenean species have been reported infecting thorny skate across the Atlantic Ocean. In the present study, we intend to fill in the knowledge gap on monogenean parasites infecting thorny skate in the northern part of its range and thus indirectly assess the connectivity between the thorny skate populations off the Svalbard coast and from previously studied locations. 46 monogenean individuals were recovered from 11 specimens of thorny skate. Following morphological and molecular assessment, two species of monogeneans, Acanthocotyle verrilli and Rajonchocotyle emarginata, were identified. The results serve as the northernmost record for both parasite genera and the first record of monogenean species off Svalbard. Detailed morphometric evaluation revealed a relatively high level of morphological variation in A. verrilli compared to its congeners. Phylogenetic reconstruction placed A. verrilli in a well-supported clade with A. imo. Our study also suggests high diagnostic significance of sclerotised structures in the identification of Rajonchocotyle. Even though the occurrence of two directly transmitted parasite species supports the previously suggested long-distance migration of A. radiata, future studies employing highly variable genetic markers are needed to assess the ongoing and historical migration patterns.HighlightsFirst record of monogenean species in SvalbardNorthernmost record for representatives of Acanthocotylidae and HexabothriidaeTransatlantic occurrence of parasites supports connectivity of thorny skate populations

An entomological survey was carried out in the municipalities of Juchique de Ferrer and Colipa in the north-central area of the State of Veracruz, Mexico, where some human cutaneous leishmaniasis cases have been recorded. These sampling efforts were undertaken to identify potential vectors of Leishmania species in that area. A total of 123 specimens were obtained, corresponding to one species of the Bruchomyiinae genus Nemapalpus Macquart, and six species of the Phlebotominae genus Lutzomyia França. Additional morphological characters of the poorly known male of Nemapalpus dampfianus Alexander and a description of Lutzomyia leohidalgoi sp. nov., based on male and female characteristics, are presented with illustrations. This is the first record from Veracruz of Nemapalpus dampfianus Alexander, Lutzomyia serrana (Damasceno & Arouck) (species group Verrucarum), Lutzomyia (Psathyromyia) cratifer (Fairchild & Hertig), and Lutzomyia (Helcocyrtomyia) oppidana (Dampf). Lutzomyia (Lutzomyia) cruciata (Coquillett) and L. (Psathyromyia) shannoni (Dyar) are anthropophilic species already known from Veracruz.

The genus Microgecko Nikolskii, 1907 (Gekkonidae) currently includes eight species distributed from western Iran to north-western India and Pakistan. During field research in Iraq, we found a population of the genus near to the Darbandikhan Lake in the north-eastern part of the country. Because members of the genus are characterized by a higher level of morphological and genetic diversity, we investigated the population using both morphological and molecular approaches. The phylogenetic analyses based on a fragment of the mitochondrial marker cytochrome b and morphological characters showed that our investigated population belongs to M. helenae fasciatus. This is the first record of the genus and species for Iraq. Moreover, the phylogenetic structure within M. helenae shows divergences that suggest the elevation of M. h. fasciatus to species level.

Seven new freshwater ameirids were discovered in the Australian subterranean habitats, six of which would fit into the present unsatisfactory diagnosis of the genus Stygonitocrella Reid, Hunt & Stanley, 2003. Two of them were discovered in Pioneer Valley, Queensland, representing the first record of this genus in eastern Australia. Four other species were collected from the Pilbara region in Western Australia, the same region in Australia where the first three representatives of this genus were reported. An additional new species was collected in the Kimberley region in Western Australia and could not be assigned to the revised genus Stygonitocrella, but has some remarkable similarities with species that were in the past considered to be members of this genus. In order to assess the most natural allocation of these ameirid taxa, a revision of the genus Stygonitocrella was made, based on a cladistic approach by using 57 phylogenetically informative morphological characters. The phylogenetic analysis revealed the presence of six monophyletic groups, giving ground for the establishment of six new genera, three of them created to accommodate a single new Australian species: Kimberleynitocrella billhumphreysi gen. et sp. nov. from several bores in the Argyle Diamond Mine and Ord River in the Kimberley region in Western Australia, Gordanitocrella trajani gen. et sp. nov. from three different localities in the Pilbara region in Western Australia, and Lucionitocrella yalleenensis gen. et sp. nov. from a single bore on the Yalleen Station, also in the Pilbara region in Western Australia. All three new Australian genera have a basal position on the phylogenetic tree, because they share several plesiomorphic characters; nevertheless they are well defined by the combination of apomorphic and plesiomorphic features. The generic diagnosis of Stygonitocrella is emended and the genus redefined to include only four species: S. montana (Noodt, 1965) from Argentina (the type species), S. dubia (Chappuis, 1937) and S. guadalfensis Rouch, 1985 from Spain and S. sequoyahi Reid, Hunt & Stanley, 2003 from the United States. The Cuban S. orghidani (Petkovski, 1973) was left as incertae sedis in this genus. The subgenus Fiersiella Huys, 2009 is established as a junior subjective synonym of Stygonitocrella. Generic diagnoses are emended for the monospecific Australian genus Inermipes Lee & Huys, 2002, the monospecific Japanese genus Neonitocrella Lee & Huys, 2002 and the North American genus Psammonitocrella Huys, 2009, that contains two species. The genus Reidnitocrella gen. nov. is erected to accommodate three closely related central Asian species: R. tianschanica (Borutzky, 1972) comb. nov., R. pseudotianschanica (Sterba, 1973) comb. nov., and R. djirgalanica (Borutzky, 1978) comb. nov. Also, after carefully examining the available published information on R. tianschanica another new species is recognized in this genus: R. borutzkyi sp. nov. The genus Eduardonitocrella gen. nov. is erected for the Mexican E. mexicana (Suárez-Morales & Iliffe, 2005) comb. nov. The newly established genus Megastygonitocrella gen. nov. is the largest one in this group of freshwater ameirids, containing the following 11 species: M. trispinosa (Karanovic, 2006) comb. nov. (type species), M. bispinosa (Karanovic, 2006) comb. nov., M. unispinosa (Karanovic, 2006) comb. nov., M. ecowisei sp. nov., M. dec sp. nov., M. pagusregalis sp. nov., M. kryptos sp. nov., M. karamani (Petkovski, 1959) comb. nov., M. petkovskii (Pesce, 1985) comb. nov., M. ljovuschkini (Borutzky, 1967) comb. nov. and M. colchica (Borutzky & Michailova-Neikova, 1970) comb. nov. The first five species are endemic to the Pilbara region in Western Australia, the next two are described from Queensland, M. karamani is known from Slovenia, M. petkovskii from Greece, while the last two species are endemic to the Caucasus. A Tethyan origin for this genus is here hypothesized. New locality data is presented for the first three species, which revealed that M. trispinosa is the most common and widely distributed member of this group (although restricted to a single Australian region), while M. bispinosa and M. unispinosa are short range endemics. A key to species is provided for each polytypic genus, as well as a key to genera of Stygonitocrella s. l.

The Northeast region of Brazil has gaps in the distribution of several species of crustaceans. In the last decade, the increase in the sampling effort and the elaboration of species lists have minimized this problem. In some cases, studies suggest that these “gaps” in the distribution of some organisms may be a natural part of a discontinuity in their geographical limits. During the lobster fishing expeditions on coral reefs in the north coast of Rio Grande do Norte (RN), for the first time, the spider crab Mithrax tortugae was captured in RN. After capture, some specimens were sent to the UFRN aquatic fauna laboratory for identification and biometrics. After confirmation of identification, they were deposited in the UFRN invertebrate collection. Thus, the present work aims to update the distribution area of the species, and to fill an existing gap for the Northeast region, bringing the first record of Mithrax tortugae on the coast of Rio Grande do Norte.

We describe a new agglutinated monothalamous foraminiferal species, Capsammina crassa sp. nov., based on integrated observations of the test morphology and the chemical characteristics of materials composing the test. The new species was found at a depth of <60 m on the East coast of Korea. The test morphology is typical of the genus Capsammina, comprising two or more mica plates with a ring of finely agglutinated mineral grains sandwiched between them and surrounding the cell body. There is no distinct test aperture. Elemental analyses of the agglutinated grains revealed 15 different types of mineral grains of which quartz is the most abundant. The surface areas of grains exposed on fractured surfaces ranged from 1.6 to 7,700 μm2 and the large plate-like grains forming the upper and lower surfaces measured about 420–2,350 μm in maximum width. The new species is morphologically similar to C. patelliformis, however, the differences in size, distribution area and depth support that these two species are distinct. This discovery is the first record of the genus Capsammina from the North Pacific. Therefore, it extends the biodiversity and geographical distribution of the genus Capsammina, which has been reported only from the bathyal NE Atlantic. Our finding also suggests the possibility of additional discovery of monothalamous foraminifera from around Korea.
