VERTEBRATES FROM THE WOOD BAY GROUP AND THE POSITION OF THE EMSIAN-EIFELIAN BOUNDARY IN THE DEVONIAN OF VESTSPITSBERGEN

This paper deals with various vertebrates from the Verdalen Member of the Stjørdalen Formation of the Wood Bay Group, Vestspitsbergen, or layers presumably belonging to this member, including the thelodont scales Amaltheolepis winsnesi n.g., n.sp. (earlier known from a locality in Sørkapp Land), the heterostiid brachythoracid Herasmius granulatus n.g., n.sp. and the porolepiform crossopterygian Heimenia ensis n.g., n.sp., the latter with scales intermediate in some ways between those of Porolepis on the one hand, and the Holoptychiidae on the other. Amaltheolepis and Herasmius are not yet known to occur outside Vestspitsbergen; Heimenia is represented in a Devonian material from Anderson River, Northwestern Canada and perhaps also in the Placo-derm Sandstone of Poland. A critical appraisal of the arthrodire faunas of the Wood Bay Group shows that most of the earlier recorded occurrences of Homostius and Heterostius in these layers pertain to euleptas-pid brachythoracids, that the Heterostiidae and Homostiidae are also represented, but only in the Stjordalen Formation, and that the youngest member of the Euleptaspididae, occurring in the Stjordalen Formation, may be closely related to another euleptaspid in the Upper Emsian Heisdorf Beds of the Rhinish sequence (which occurs in association with Ohiolepis scales). The palaeontological evidence may indicate that the Wood Bay Group does not belong to the Lower Devonian in its entirety but includes Middle Devonian strata in its uppermost part.

DESCRIPTION OF THE CALIGINOSUM SPECIES GROUP OF THE GENUS PISON JURINE (HYMENOPTERA: SPHECIDAE: LARRINAE)

A new species group of Pison (comprising P. caliginosum Turner from Australia and Norfolk I., P. mandibulatum Turner from southwestern Australia, and P. pyrrhicum sp.n. and P. weiri sp.n. from northern Australia) is recognised. A lectotype is selected for P. mandibulatum . All species possess an apically broad mandible unique within the genus. Nothing is known of the nesting biology of these species.

THE PROBLEMATIC GENUS MOBERGELLA FROM THE LOWER CAMBRIAN OF THE BALTIC AREA

An unusually well preserved phosphatic fauna has been found in boulders of Lower Cambrian conglomerate from Venenäs, on the Skäggenäs Peninsula in the Baltic Sea. The fauna is dominated by the problematic fossil Mobergella holsti (Moberg 1892). The present material shows that this form is composed of three separate taxionomical units, and two new species- M. radiolata n. sp. and M. turgida n. sp.-are introduced besides M. hoisti. The new evidence seems to discard entirely the theory that Mobergella has been a free-living organism of monoplacophoran type. Instead, the interpretation of the shell as the operculum of a tube-dwelling organism seems to be the most plausible one. The tube itself, however, has not been recovered.     

ANGIOSPERM WOOD FROM THE UPPER CRETACEOUS OF CENTRAL CALIFORNIA. III

Five species representing five genera are described. The specimens are part of a collection of woods from the Upper Cretaceous Panoche Formation of central California. Lardizabaloxylon cocculoides sp. n. resembles wood of those species of Cocculus of the Menispermaceae lacking included phloem. Carpinoxylon ostryopsoides sp. n. is similar to the wood of the Coryleae of the Betulaceae, particularly Ostryopsis. Riboidoxylon cretacea gen. et sp. n. is similar to the wood of Ilex of the Aquifoliaceae and also falls within the range of variation of the woods of the two closely related families, the Grossulariaceae and the Escalloniaceae. Mulleroxylon eupomalioides sp. n. falls well within the range of variation of the woods of the Magnoliaceae.     

EOCENE ALGAE AND PLANT HAIRS FROM THE GREEN RIVER FORMATION OF WYOMING

Four new species of algae and two kinds of fossil plant hairs are described from a rich oil shale bed of the mid-Eocene Green River Formation of Wyoming. Two of the algae belong to the Cyanophyceae and two to the Chlorophyceae. On the basis of their morphology alone, they are assigned to four new species among four genera, as follows: Symploca hedraia, sp. n.; Stigonema anchistina, sp. n.; Schizochlamys haywellensis, sp. n.; and Spirogyra wyomingia, sp. n. One kind of fossil plant hair is similar to those observed in organic sediments of an existing lake and identified with trichomes on the under surface of live oak leaves (Quercus virginiana). Assignment of the fossil trichomes to a taxon is not warranted at present.     

THE AUSTRALIAN SPECIES OF ORIUS WOLFF (HETEROPTERA: ANTHOCORIDAE)

Abstract
Triphleps australis China, 1926 is synonymised with Anthocoris tantillus Motschulsky, 1863 (both now in Orius Wolff) and additional taxonomic and distributional data are provided for O. tantillus and O. armatus Gross, 1954. O. heterorioides sp. n. and O. chadwicki sp. n. are described. The 4 species are keyed and their placements within the genus are discussed.     

THREE NEW SPECIES OF POLISTES LATREILLE (HYMENOPTERA: VESPIDAE) FROM PAPUA NEW GUINEA, WITH NOTES ON THE TAXONOMIC STATUS OF THE SUBGENUS STENOPOLISTES VAN DER VECHT

Abstract
Three new species of Polistes Latreille are described from Papua New Guinea. Of these, P. occultus sp. n. largely fits the diagnosis of the subgenus Stenopolistes van der Vecht. However, while P. watutus sp. n. and P. medius sp. n. have the jugal lobe of the hind wing defined by a wide incision (an apomorphic character of Stenopolistes ), in the other characters distinguishing Stenopolistes and the subgenus Polistella Ashmead have states typical of Polistella. If Stenopolistes is regarded as a subgenus, then Polistella is defined only by a symplesiomorphy, thus Stenopolistes must be synonymised under Polistella.     

NOTES ON THE NATURE AND ENVIRONMENTAL SIGNIFICANCE OF THE RECEPTACULITACEAE

Recent studies of representatives of the family Receptaculitaceae (Receptaculitidae) suggest that it comprises dasycladacean-like algae which flourished in warm shallow seas, perhaps largely confined to within 15° of the paleoequator. Ischadites (Neoischadites) n. subg. is erected. The type species is Ischadites (Neoischadites) struszi n. sp., from the Lower Devonian Garra Formation of central western New South Wales, Australia.     

FOUR NEW SPECIES OF TAMBJA BURN, 1962 (NUDIBRANCHIA: POLYCERIDAE) FROM THE INDO-PACIFIC

The genus Tambja previously included 24 described species. Fournew species, T. tentaculata n. sp., T. gabrielae n. sp., T.zulu n. sp. and Tambja victoriae n. sp., from the Indo-Pacificare described. Tambja tentaculata n. sp., from Guam, is theonly known species in the genus with well developed, dorsolaterallygrooved, oral tentacles. Its inner lateral teeth have a bifidinner cusp with two long, sharp denticles. The oral tentaclesof T. tentaculata are more typical of Roboastra species, whilethe shape of the inner lateral teeth is more typical of Tambja.Nevertheless, the arrangement of the two cusps of the innerlateral teeth and the presence of a rachidian tooth withoutdenticles and with a central notch at the anterior edge, typicalof the species of the genus Tambja, suggest the placement withinthis genus. Tambja gabrielae n. sp., from Indonesia and PapuaNew Guinea, has dark green to dark brown ground colour withbright yellow patches scattered on the body. Tambja zulu n.sp. from Durban, South Africa, is characterized by a black groundcolour with slender yellow longitudinal lines. Tambja victoriaen. sp. is a new species from Papua New Guinea and Australiathat has frequently been misidentified as Roboastra arika, characterizedby its blue body colour and yellow lines. The four species aredistinguishable based on differences in body coloration, ofcharacters of the radula and of the reproductive system. Anoverview on distinguishing features of all known Indo-PacificTambja species is presented. (Received 21 June 2004; accepted 20 January 2005)
