Systematic Knowledge

The present study is a further contribution to the systematic knowledge of the shallow water marine ostracodes from the Brazilian oceanic islands. A total of 14 species belonging to 10 genera and eight families is herein identified. One new genus and species are described and illustrated: Berguecythere insularis gen. nov., sp. nov. In addition to this new taxon, the abundant species Loxocorniculum tricornatum Krutak, 1971, widely distributed in recent sediments in the Gulf of Mexico, Caribbean, north and northeast of Brazil and the Rocas Atoll, along with the cosmopolitan tropical ostracode Triebelina sertata Triebel, 1948, were also identified at specific level. The remaining 11 species were left at the genus level, and should provide new species. Ecological, zoo- and paleozoogeographical aspects were also briefly discussed.

Basal Structure

Abstract. A very distinctive new deep-photic coccolithophore is described from the NE Indian Ocean. The new species is trimorphic with: 200–300 body coccoliths bearing low spines attached by narrow stems to a basal narrow-rimmed placolith structure; up to 18 circum-flagellar coccoliths with tall sail-like spines; and up to 22 coccoliths with moderately elevated spines occurring both around the circum-flagellar coccoliths and antapically. These features make the coccolithophore unique and require placement in a new species and genus. The basal structure, however, shows similarities to a recently recognized group of narrow-rimmed placoliths. Hence, the new coccolithophore provides some support for this grouping as a significant addition to our understanding of coccolithophore biodiversity, and potentially an explanation for a set of anomalous molecular genetic results. In addition the new taxon provides further evidence that the deep-photic coccolithophore community is more diverse than has been assumed.

Insufficient Information

Sphaeraphodius gaohani Kakizoe, Jiang & Wang, a new genus and new species of the tribe Aphodiini, is described based on two female specimens from Guangxi, China. This new genus differs considerably from any previously known genera of Aphodiini by dorsally swollen body covered by considerably long setae, and lack of transverse setiferous carinae on outer surfaces of meso- and metatibiae. This new taxon is found sympatrically with the termite Macrotermes sp. in the field. Therefore, this species is perhaps termitophilous, but we cannot conclude it at this time due to the insufficient information available in the field.

AbstractSyringoplutarchusia, a new genus of the syringicolous feather mite family Syringobiidae (Pterolichoidea), is described based on a single new species, S. nordmanni sp. nov., collected from the feather quills of a museum specimen of the Black-winged Pratincole Glareola nordmanni Fischer, 1842 (Glareolidae). Absence of adanal discs and complete reduction of setae d and e on tarsi IV in males of the new genus is unique in this family. The highly elongated body shape of both sexes is most similar to the genera Plutarchusia Oudemans, 1904 and Paidoplutarchusia Dabert, 2003 but strong sclerotization of coxal fields and hypertrophied posterior legs with variously shaped apophyses resemble more advanced syringobiid mites, e.g. Syringobia Trouessart et Neumann, 1888. Syringoplutarchusia represents the first syringobiid from this host family. The taxonomic status of the new taxon is discussed.

Superficial Similarity

A decade-long survey of ground waters in the state of Andhra Pradesh, India, has so far yielded over sixty new crustacean taxa, belonging to Copepoda, Bathynellacea, Amphipoda, Isopoda, and Ostracoda. This paper describes a new genus and species attributable to the phreatoicidean isopod family Hypsimetopidae Nicholls, and provides ecological and behavioural observations. The new taxon was found in Guthikonda Cave, which is about 8 km from Piduguralla town in the Palnadu area of Andhra Pradesh State. The species belonging to this clade are unusual in that their dorsoventrally flattened pleotelson gives them a non-phreatoicidean appearance. Because the postanal margin is missing, as in other members of the Hypsimetopidae, this is a superficial similarity rather than homology with other isopods. Other unusual features include robust blunt denticles on opposing margins of the pleotelson and protopod of the uropods. The species in this clade, of which Andhracoides shabuddin gen. nov., sp. nov. is only the first to be described, are related to Nichollsia Chopra & Tiwari, found in northeastern India, and to Pilbarophreatoicus Knott & Halse from the Pilbara region of Western Australia. The new species differs from its undescribed congeners in being nearly devoid of dorsal setae; other species of Andhracoides gen. nov. are much more hirsute.

Abstract A new genus and new species of pilumnid crab, Ericiolumnus symbioticus (Decapoda: Brachyura), is described from the sponge Callyspongia Duchassaing & Michelotti, 1864 (Porifera: Callyspongiidae) in reefs in Lombok, Indonesia. The new taxon is characterized, among several characters, by the unusual shape of the carapace, which possesses sharp anterolateral teeth armed with secondary spinules, and prominently spinulous ambulatory legs. Another pilumnid, Pseudactumnus pestaeBalss, 1933, is shown to be a junior synonym of Actumnus asper (Rüppell, 1830). The pilumnid genus PseudactumnusBalss, 1933 is additionally synonymised with ActumnusDana, 1851. A review of symbiosis in Pilumnidae is also presented.

Nautilocaris saintlaurentae gen. nov., sp. nov., is described and illustrated from hydrothermal vents in the North Fiji Basin and Lau Basin in the south-western Pacific. This new taxon is assigned to the Alvinocarididae. It has a well-developed, dorsally dentate rostrum, carapace with pterygostomian spine present, eye broadly fused mesially, epipod–setobranch complex present above pereopods, and appendix internae on second to fourth pleopods greatly reduced. This combination of characters places it in an intermediate position between a group of species in the genus Alvinocaris with well developed, dorsally dentate rostrum, carapace with pterygostomian spine present, eyes narrowly fused mesially, epipod–setobranch complex absent and well-developed appendices internae on second to fourth pleopods, and Mirocaris fortunata with rostrum unarmed, carapace with rounded pterygostomian angle, eye broadly fused mesially, epipod–setobranch complex present above pereopods and appendices internae on second to fourth pleopods greatly reduced. The habitat of the new species is briefly described.

Eocorythoderus incredibilis, a new genus and new species, of Corythoderini is described. This new species was found infungus gardens of Macrotermes gilvus (Hagen, 1858) in Angkor Wat, Cambodia. The new taxon is a flightless, mi-crophthalmic species and the first corythoderine associated with Macrotermes Holmgren, 1910. The beetles were ob-served being carried by worker termites. Eocorythoderus is probably closely related to the genera Corythoderus Klug,1845 and Paracorythoderus Wasmann, 1918 (also Corythoderini). Some character states shared with the distantly-related termitophilous scarab genus Termitotrox Reichensperger, 1915 (Termitotrogini) are noted, and proposed as convergent.

Marine Reptile

A partial skeleton of a plesiosaur (Reptilia: Sauropterygia) from the Hiccles Cove Formation (Middle Jurassic: Callovian) of Melville Island, Canadian Arctic Archipelago, is the first marine reptile fossil with well-preserved skull from the Canadian Arctic and represents a new genus and species of Rhomaleosauridae ( Borealonectes russelli ). The Rhomaleosauridae are a problematic group, and a review of the current status of included taxa is given prior to the description of the Canadian material. The holotype and only known specimen of the new species consists of the skull, anterior cervicals, and right forelimb. The new taxon is characterized by the large prefrontal and the configuration of the postorbital bar in which the postfrontal is excluded from the supratemporal fenestra; these are potentially unique features among rhomaleosaurids. It exhibits a combination of primitive and derived characteristics that are variable among rhomaleosaurids, such as the absence of the dorsomedian foramen and anterior pterygoid vacuity on the palate, and the presence of straight shaft of humerus. The occurrence of this specimen suggests a global distribution of rhomaleosaurids, and it is also significant as one of the few Jurassic plesiosaurs known from North America.

Kotumsaridae, a new family of amphipod crustaceans is described from Kotumsar Cave in the state of Chhattisgarh, India. The family is based on Kotumsaria bastarensis, new genus and species, which is the only known member of the new family recorded to date. Although the new family appears to share some morphological characters with several other taxa from the southern hemisphere considered members of the superfamily Crangonyctoidea, including the New Zealand endemic genus Paracrangonyx, both its taxonomic and phylogenetic affinities remain unclear. Specimens of the new taxon, measuring just over 2 mm in length, were collected from the sediments of a pool in Kotumsar Cave but are believed to have migrated from deeper interstices. Kotumsaria bastarensis is only the third subterranean amphipod recorded to date from the Indian subcontinent.
