New records of Conidae (Mollusca: Gastropoda) from the New Zealand region

Abstract

Conus howelli Iredale is recorded from New Zealand. C. howelli and C. raoulensis Powell are considered to be very closely related, and Kermasprella Powell is thus probably a svnonvm of Endemoconus Iredale. C. teramachii (Kuroda) and C. smirna Bartsch ' Rehder are recorded from off northern New Zealand, and the known range of C. kermadecensis Iredale is extended southward.     

Some osteological differences between the blennioid fishes Limnichthys polyactis and L. rendahli,with comments on other species of Creediidae

Abstract

The two endemic species of New Zealand Limnichthys differ in several osteological characters. L. polyactis differs from L. rendahli in having a rayed dorsal margin of the opercle (cf. entire), little or no gap between the lower limb of the coracoid and the pelvis (cf. wide gap), one epural (cf. two), and narrow posterior neural and haemal spines (cf. wide spines). Comments are given on some characters in the other 10 recognised named species of Creediidae. Squamicreedia obtusa is removed from the Creediidae, and is provisionally placed in the Percophididae.     

Living Pleurotomariidae (Mollusca: Gastropoda) from the South Pacific

Abstract

Perotrochus caledonicus n.sp. is described from the upper bathyal south of New Caledonia, an old area that has remained stable over the past few million years, and P. tangaroana n.sp. is described from the bathyal of Lau Ridge. These represent the first occurrence of living Pleurotomariidae in the South Pacific; other representatives of the family are restricted to Southeast Asian seas or the Atlantic.     

New species of Nystiellidae and Epitoniidae (Mollusca: Gastropoda) from the northeastern Pacific

Some nystiellid and epitoniid species from the eastern Pacific Ocean from Oregon to Alaska are discussed and six new species described herein: Eccliseogyra frausseni from deep water off southeastern Alaska; Iphitus clarki, Iphitus wareni, Murdochella turritelliformis and Epitonium nearense, all from the Aleutian Islands; and Claviscala dushaneae from deep water off Oregon.     

Eulimid gastropods parasitic on echinoderms in the New Zealand region

Abstract

Eulimindae (Prosobranchia) of the New Zealand region that parasitise echinoderms are recorded and discussed. Fuscapex ophioacanthicola n.gen. & sp. is parasitic on Ophioacantha sp., Ophieulima fuscoapicata n.sp. is a parasite of Ophioactis profundi Lütken & Mortensen, Punctifera ophiomoefrae n.gen. & sp. lives partly buried among the radial shields of Ophiomoeris projecta Matsumato, and Stilapex sp. is recorded, but not described, from Ophiothrix oliveri Benham (all hosts ophiuroids). Stilifer sp. lives in galls in an undescribed oreasterid (Asteroidea). Annulobalcis marshalli n.sp. is described from Crotalometra rustica (A. H. Clark) (Crinoidea). Eulima infrapatula Murdoch & Suter is transferred to Sabinella Monterosato and recorded from Ogmocidaris benhami Mortensen; Fusceulima goodingi n.sp. is described from Centrostephanus rodgersi (A. Agassiz) (both hosts echinoids). Two earlier records of sea urchin parasites from New Zealand are discussed, and the species are referred to Pelseneeria.     

Additional dextral triphorids (Mollusca: Gastropoda) from New Zealand

Abstract

Socienna maoria Finlay and Mendax duplicarinata Powell are referred to Metaxia Monterosato. Metaxia solitaria n.sp., Socienna cracens n.sp., and S. cracens regia n.subsp. are described. Additional range data are provided for Metaxia exaltata (Powell).     

New species of Halacaridae (Acari) from New Zealand

Abstract

Seven new taxa of marine mites (Halacaridae) are described from the marine littoral zone of northern and southern New Zealand: Agauopsis novaezelandiae, A. luxtoni, Halacarellus lubricus, Copidognathus lubricus, Simognathus glaber, S. glareus, and Rhombognathus novaezelandicus. A list of halacarid species known from New Zealand waters is added.     

Patellogastropoda and Vetigastropoda (Mollusca,Gastropoda) from the marine Jurassic of Patagonia,Argentina

Gastropod faunas from the Early Jurassic (Late Pliensbachian–Early Toarcian) marine deposits of Chubut Province, Argentina, are described from Lomas Occidentales, Cerro La Trampa and Puesto Currumil localities, representing eight species, three of them new. These are Scurriopsis? sp., Chartronella gradata sp. nov., Calliotropis? sp., Pleurotomaria sp., Leptomaria sp., Hamusina? wahnishae sp. nov., Colpomphalus musacchioi sp. nov. and Jurassiphorus? cf. triadicus Haas. The gastropod assemblage reported here testifies paleobiogeographical connections with other coeval gastropod associations from the western Tethys. However, Chartronella, Hamusina and Jurassiphorus may represent survivors of Triassic associations, considering the ancient seaway from Peru as the most plausible hypothesis for biotic exchange of these faunas during the Late Triassic–Early Jurassic boundary. An abundant and diverse invertebrate fauna such as corals, echinoderms, cephalopods, brachiopods, bivalves and other gastropods found in association with the gastropods described here characterises a shallow marine environment for the gastropod-bearing rocks.http://www.zoobank.org/urn:lsid:zoobank.org:pub:7B8EAFC0-3AC0-4F91-97A5-22AAC6A19909     

Notes on inland water molluscs from Egypt (Mollusca: Gastropoda,Bivalvia)

Abstract

A report on two new collections of fresh- and brackish water molluscs in Egypt is filling gaps in the generally known distribution pattern. The recent status of the mollusc fauna of Birket Qarun (Fayum), changed by introduction of marine species into the brackish water lake, is documented.     

New Zealand Recent Hyriidae (Mollusca: Bivalvia: Unionida)

The New Zealand freshwater mussels are taxonomically revised and compared with key Australian and South American taxa using DNA sequence data. Three living species are recognised: Echyridella menziesii, Echyridella aucklandica and Echyridella onekaka. Cucumerunio websteri websteri and Cucumerunio websteri delli, are treated as junior synonyms of Unio aucklandica, which is transferred from Cucumerunio (and Hyridella) to Echyridella. Lectotypes are designated for Unio waikarensis and Unio hochstetteri, which are illustrated together with primary type specimens of other relevant taxa. The type locality of U. aucklandica is restricted to the catchment of the Kawakawa River.     

New Apioninae (Coleoptera: Brentidae) in Dominican amber

The following new species of Apioninae weevils (Coleoptera: Brentidae) are described from Dominican amber. Toxorhynchus leptorhinusn. sp., Toxorhynchus robustusn. sp., Toxorhynchus amphioculusn. sp., Toxorhynchus atriartusn. sp., Toxorhynchusatriantenusn. sp. and Toxorhynchus hispaniolicusn. sp. are members of the Toxorhynchus decoloratum species group. Toxorhynchus microsomusn. sp., Toxorhynchus stenelytrusn. sp., Toxorhynchus dominicanusn. sp., Toxorhynchus convexusn. sp., Toxorhynchus fuscocorpusn. sp., Toxorhynchus hispidulusn. sp. and Toxorhynchus convexoculusn. sp. are members of the Toxorhynchus sordidum species group. A new subtribe, Stenapiina n. subtribe of the tribe Toxorhynchini, is erected. New species Apionion homochrononn. sp.,Apionion kallimosumn. sp.,Apionion formoculusn. sp. and Stenapion levigatumn. sp. are described. The dominate species of the genus Toxorhynchus and especially those in the Toxorhynchus decoloratum and Toxorhynchus sordidum species groups in Dominican amber are now absent from the West Indies. A systematic update of extant representatives of Apioninae in Hispaniola is provided.http://www.zoobank.org/urn:lsid:zoobank.org:pub:2D4A59DB-E804-4B45-8773-C027A8AD5A02     

The genus Williamia in the western Pacific (Mollusca: Siphonariidae)

Abstract

The taxonomic status and synonymy of Williamia Monterosato, 1884 are discussed. Williamia is retained in preference to Allerya Mörch, 1877 and Brondelia Bourguignat, 1862, both of which have priority. Roya Iredale, 1912 is transferred from Trochidae to Siphonariidae as a synonym of Williamia. Roya kermadecensis Iredale, 1912 is synonymised with Capulus nutatus Hedley, 1908, which in turn is placed as a geographic subspecies of W. radiata Pease, 1861. Allerya japonica Habe, 1962 is considered a probable synonym of W. radiata. W. maxwelli n.sp. is described from the Upper Oligocene to Lower Miocene of New Zealand. Roya spongotheras Bertsch, 1980 is transferred to an undescribed genus of the Tylodinidae.     

Descriptions of new taxa of the Clausiliidae from Turkey (Mollusca: Stylommatophora)

Summary

Several new taxa of the Clausiliidae were described From Turkey: Dobatia multidentifera n. sp., Albinaria monocristata n. sp., Albinaria basalifera n. sp., Roseniella (Chavchetia) n. subgen., Roseniella (Chavchetia) rufina n. sp., Armenica euprepes truncata n. ssp., Armenica multispirata n. sp., Armenica bicarinata grisea n. ssp., Kazancia n. gen., and Kazancia monticola n. sp. Investigations were made of the genital morphology of some species, and the arrangement of the taxa in Nordsieck’s classification (H, NORDSIECK 1979) is discussed.     

The recent New Zealand species of Triforis (Gastropoda: Triforidae)

Paramendax apicina Powell and Mendax attenuatispira Powell are referred to genus Triforis Deshayes; T. antepallaxa, T. blacki, and T. tui are described as new; and a species close to the South Australian Triforis epallaxa (Verco) is recorded from New Zealand waters. Paramendax Powell is transferred from the Cerithiopsidae to the Triforidae as a subgenus of Triforis. It is suggested that the Recent South African Cerithiella nonnitens Barnard is referable to Triforis.     

New species and records of Stigmaeidae (Acari: Prostigmata) from New Zealand - ID. Genus Stigmaeus Koch

Abstract

Stigmaeus arboricola, S. montanus, S. luxtoni, and S. novazealandicus are described as new species, and the larva of S. loadmani is described. Several new records are noted, and a key is given to the New Zealand species of Stigmaeus.     

New species of the subfamily Cossoninae (Coleoptera: Curculionidae) in Dominican amber

The following new genus and seven new species of Cossonine weevils (Curculionidae: Cossoninae) are described from Dominican amber: Acamptus exilipes Poinar and Legalov, n. sp. (similar to A. rigidus), Caulophilus camptus Poinar and Legalov, n. sp. (similar to C. bennetti), Caulophilus elongatus Poinar and Legalov, n. sp. (similar to C. swensoni), Caulophilus ruidipunctus Poinar and Legalov, n. sp., Dryotribus pedanus Poinar and Legalov, n. sp. (similar to D. amplioculus), Ogygius obrieni Poinar and Legalov, n. gen., n. sp. (similar to the genus Apotrepus), and Stenotrupis pumilis Poinar and Legalov, n. sp. (similar to S. breviscapus). A key to the Dominican amber species of the genus Caulophilus is provided. Based on the extant weevil fauna, it appears that the Hispaniolan Cossonine were more diverse in the Tertiary than at present. http://zoobank.org/urn:lsid:zoobank.org:pub:14D1CFC0-4967-4D22-888B-0DE3E157D6BD
