Petraliellidae Harmer, 1957 (Bryozoa: Cheilostomata) from Queensland,Australia

Several species of the family Petraliellidae were first described from the coast of Queensland, including the type species of Sinupetraliella, S. litoralis. These species are redescribed from type, or topotype specimens, and include Petraliella concinna, which has not been certainly found since its introduction in 1891; lectotype material is designated for P. buski and P. magna. Six other species are described from Queensland, P. crassocirca, P. dentilabris, P. dorsiporosa, Mucropetraliella bennetti, M. serrata and M. tuberosa. The species Mucropetraliella tuberosa is a new addition to the Queensland fauna and is described and illustrated here for the first time since its introduction in 1884. The characters of the family Petraliellidae are briefly discussed and the genera to which the Queensland species are assigned is reviewed. A taxonomic key to the ten Queensland petraliellid species described is also provided.

Abstract

The new gammarideans Photis nigrocula, P. phaeocula, and Halice sublittoralis are described from grab samples taken from the North Arm of Port Pegasus, where they appear to be the most abundant amphipods on the sandy-mud substrate. They are illustrated and compared with closely related taxa.     

Dasycladales from the Permian Jamal Formation of the Shotori Mountains,northeast Iran

Calcareous algae of the Permian Jamal Formation were studied in three sections of the Shotori Mountains, located in northeastern Iran. In this paper, four genera including Imperiella Elliott and Süssli, Nanjinoporella Mu and Elliott, Tabasoporella nov. gen., and Pseudotabasoporella nov. gen. are described from the Howz-e Dorah locality, which is exposed about 2 km northeast of the type section of Jamal Formation in Mount Jamal. Tabasoporella nov. gen. is characterized by metaspondyl arrangement of phloiophore and wine-glass-shaped laterals with a stalk grouped to tufts. The individual tufts are separated by a ring-like cavity appearing as triangular, oval, or trapezoid in longitudinally dissected section. The arrangement and shape of the laterals in Pseudotabasoporella nov. gen. is similar to Tabasoporella nov. gen., but there are no cavities between the tufts. All four genera are highly developed and limited to the Permian period. They disappear at the end of Permian and are not found in the Triassic sediments. Until today, two species of Imperiella are found in Iran and Afghanistan. I. iranica Elliott and Süssli was described only from the Ruteh Formation of Alborz Mountains in north Iran and I. afghanica was described from the Permian of Afghanistan. The Jamal Formation of the Shotori Mountains is the second locality where both species are discovered. Moreover, species I. crassiparietalis and I. gracilis are the two new species described here. The genus Nanjinoporella—with type species N. pagoda Mu and Elliott—was known from the Permian (Artinskian) Chishia Formation of Nanjing, China. We describe the new species Nanjinoporella iranica from the Permian Jamal Formation of the Shotori Mountains, northeast Iran.     

Gregarines of the Genus Lecudina (Protozoa,Apicomplexa) from Pacific Ocean Polychaetes*

The gregarine Lecudina longissima Hoshide, 1944 is described from the intestine of the marine polychaete Lumbrineris zonata (Johnson, 1901) from Santa Catalina Island, Calif. L. catalinensis n. sp. is described from the intestine of L. inflata Moore, 1911 from the same island. L. pherusae sp. n. and L. zimmeri sp. n. are described from the intestine of the marine polychaete Pherusa capulata (Moore, 1909) off Santa Catalina Island.     

Mobergellans (Problematica) from the Cambrian of Greenland, Siberia and Kazakhstan

Mobergellans are disc-shaped problematic fossils of phosphatic composition bearing prominent muscle attachment structures on the presumed internal surface. They are found exclusively in sediments of Early Cambrian age, mainly from Laurentia, Baltica and Siberia. Type material ofDiscinella brastadi Poulsen, 1932 from North-East Greenland is re-studied and synonomised withDiscinella micans (Billings, 1871). Specimens from Siberia described asD. brastadi are re-assigned toMobergella hexactina n. sp., and specimens from Siberia described asMobergella radiolata Bengtson, 1968 are re-assigned toM. sibirica n. sp.Aktugaia triangula Mis-Sarzhevsky, 1976 from Kazakhstan is redescribed, and its relationship to other mobergellans is discussed.      

Campylocentrum guarinae sp. nov. (Vandeae,Orchidaceae) from Colombia

Stempellina and Zavrelia from China (Diptera,Chironomidae, Tanytarsini)

The first records of the Tanytarsini genera Stempellina and Zavrelia in the Oriental Region based on adult males are presented. Two species, Stempellina clavata sp. n. and Zavrelia clinovolsella sp. n. from southern China, are described, and the generic diagnoses of the two genera are emended to accommodate the new species. A key to the male imagines of the genus Zavrelia is given.     

A new species of Polymastia (Porifera, Hadromerida, Polymastiidae) from the Aleutian Islands, Alaska, USA

Polymastia fluegeli n. sp. is described from deep water off the Aleutian Islands (Alaska, USA). P. fluegeli is disc-shaped and lives partly buried in the sediment, with only the papillae protruding above the surface. This new species has a basal layer of agglutinated sediment particles occurring between the choanosome and the ectosomal lower layer. This conspicuous sediment layer is not described for other species of Polymastia. Occurring spicule types and sizes are different from known species of the area.     

Actinodontum,a new genus of Desmidiaceae (Streptophyta,Viridiplantae) from tropical Africa

A new desmid genus, Actinodontum Alfinito et Coesel, is described from mountain areas of tropical Africa. The newly described genus differs from the allied genus Actinotaenium by the presence of marked teeth at the base of each semicell that alternate with those on the other semicell. Morphology of the type species, Actinodontum lomaense (Alfinito et Mazzoni) Alfinito et Coesel, is dealt with in much detail. Cosmarium basituberculoides Bourrelly et Couté and Cosmarium elgonense Kusel-Fetzmann are transferred to the new genus. The geographical distribution of the genus Actinodontum is discussed.

A new subfamily of predaceous diving beetles, Liadytiscinae subfam. nov., including two genera and four species, Liadytiscus gen. nov. (L. cretaceus sp. nov., L. longitibialis sp. nov., and L. latus sp. nov.) and Liadroporus gen. nov. (L. elegans sp. nov.), from the Late Tithonian-Berriasian (Huangbanjigou, Yixian Formation) of China is described. Two new genera, Mesoderus gen. nov. with two species, M. magnus sp. nov. and M. ventralis sp. nov., and Sinoporus gen. nov. with one species, S. lineatus sp. nov., are also described; their position in the system of Dytiscidae remains uncertain. Relationships of the taxa described with Recent and fossil taxa of the same rank and some presumable ecological features of the new taxa are discussed.     

A new Spionidae (Polychaeta) from North Carolina, and a redescription of Marenzelleria wireni Augener, 1913, from Spitsbergen, with a key for all species of Marenzelleria

Marenzelleria bastropi, a new species of Spionidae (Polychaeta) from the brackish water Currituck Sound, North Carolina, is described. The new species is characterized by the great number of chaetigers between the first neuro- and notopodial hooded hooks, the extension of the nuchal organ up to the end of chaetiger 2/middle of chaetiger 3 and the presence of about 60–90 branchiate chaetigers. Marenzelleria bastropi sp. nov. is closely related to M. neglecta (Sikorski and Bick, 2004) and Marenzelleria viridis (Verrill, 1873). Marenzelleria wireni Augener, 1913 is described here for the first time from western Spitsbergen. Adult specimens are investigated and compared with specimens from other areas of distribution. A key for subadult and adult specimens of all Marenzelleria species is provided.     

A new species of Neoheterocotyle Hargis, 1955 (Monogenea: Monocotylidae) from the gills of Pristis clavata Garman (Pristidae) from Darwin,Australia

Neoheterocotyle darwinensis n. sp. is described from between the secondary gill lamellae of the dwarf sawfish Pristis clavata Garman (Pristidae) collected at the mouth of Buffalo Creek near Darwin, Northern Territory, Australia. This is only the second monocotylid species to be described from northern Australia. N. darwinensis is distinguished from the other seven valid species in the genus by the morphology of the hamuli, the dorsal haptoral accessory sclerites and the male copulatory organ. The similarities between N. darwinensis and Nonacotyle pristis Ogawa, 1991 from the gills of the freshwater sawfish Pristis microdon Latham collected in Papua New Guinea are discussed.
