A new species of teuthid squid, Teudopsis cadominensis, is described from the Toarcian (Lower Jurassic) Poker Chip Shale of the Fernie Formation in central-western Alberta. Fossil squids are rare in the Mesozoic of North America; this species is the first record of the family Palaeololiginidae in North America and the first member of the suborder Mesoteuthina in the Jurassic of North America.

A new species of the family Anaxyelidae (Eosyntexis parva n. sp.) is described. This is the first record of the family from Lower Cretaceous Spanish amber. The specimen is mostly well preserved, except for dorsally. This makes it possible to identify several important details rarely or never observed in compression fossils. Eosyntexis spp. and the closely related genus Cretosyntexis are confined to the Eurasian Lower Cretaceous, whereas the extant monotypic genus Syntexis is restricted to western North America. The morphology of this new species suggests xylophagous habitus, and its relation with Syntexis libocedrii implies a possible relationship with burned wood, apparently a frequently available resource in northern Spanish forests of the Lower Cretaceous.

A species of the genus Isoperla Banks, 1906, I. oncocauda Huo & Du, sp. nov. is described as new to science and is the first record for the family Perlodidae from the Tianmu Mountain Nature Reserve, Zhejiang Province of eastern coastal China. Both sexes of the new species are characterized by tergum 10 with a developed process. The partially extruded aedeagus of the male is membranous without conspicuous larger sclerites and with the ventral surface covered with dense scale-like and nail-shaped spines.

The genus Smacigastes Ivanenko & Defaye, 2004 (Harpacticoida, Copepoda) is the most primitive genus in the family Tegastidae Sars, 1904, occurring in deep-sea chemosynthetic environments, such as hydrothermal vents, cold seeps, whale falls and wood falls. Our exploration of the Onnuri Vent Field, the sixth active hydrothermal vent system in the Central Indian Ridge, resulted in the discovery of a new species in the genus Smacigastes. A detailed morphological analysis of S. pumilasp. nov. reveals that it most resembles S. barti Gollner, Ivanenko & Martínez Arbizu, 2008, described from a hydrothermal vent in the East Pacific Ridge; the new species can be distinguished from the existing species by the 8-segmented female antennule, the absence of an abexopodal seta on the antennary basis, the mandibular exopod represented by a single seta and the exopod of the first leg with five setae. This is the first record of Smacigastes in the Indian Ocean. A dichotomous key to species of the genus Smacigastes worldwide is provided.

A new species, Pholis clemensi, referred to the family Pholidae, is named and described from 12 specimens taken in southern British Columbia waters and the Strait of Juan de Fuca. Pholis clemensi is compared with other members of the genus, and a key is given to the North American species.

This is the second in a series of papers intended to establish a Lower Jurassic ammonite zonation that takes into account the biostratigraphic and biogeographic peculiarities of the North American succession. In North America the lower boundary of the Toarcian is drawn at the first appearance of Dactylioceras above the last occurrence of Amaltheus and Fanninoceras. The lower Toarcian is represented by the Kanense Zone; the middle Toarcian by the Planulata and Crassicosta zones; and the upper Toarcian by the Hillebrandti and Yakounensis zones. Section 5 on the Yakoun River in the Queen Charlotte Islands is designated the stratotype for the Planulata, Crassicosta, and Hillebrandti zones; section 3 on the Yakoun River is designated the stratotype for the Yakounensis Zone; an ideal stratotype for the Kanense Zone is not presently known. Reference sections further illustrating the faunal associations that characterize the zones are designated in eastern Oregon (Snowshoe Formation) and northern British Columbia (Spatsizi Group). The Dactylioceratidae, Harpoceratinae, and Hildoceratinae provide the most important zonal indicators for the lower Toarcian; Dactylioceratidae, Phymatoceratinae, and Bouleiceratinae for the middle Toarcian; and Phymatoceratinae, Grammoceratinae, and Hammatoceratinae for the upper Toarcian. Phymatoceras hillebrandti is described as a new species.

The whip spider genus Phrynichus (Phrynichidae, Amblypygi) is widely distributed in Africa, the Arabian Peninsula and Asia with a total of 17 species. No records, however, are known from several countries in the Middle East. Here we provide the first record of a whip spider from Iran (Ilam Province), with the description and illustration of a new species, Phrynichus persicus sp. n. This discovery fills a gap in the distribution of the group that is known from both sides of this biogeographically interesting region and is also the northernmost record of the family Phrynichidae. Moreover, all distribution records of the Phrynichus species are mapped (including the first verified record of the order from the United Arab Emirates), an updated key to the species of the deflersi and ceylonicus groups is provided, and Phrynichus andhraensis Bastawade, Rao, Maqsood Javed and Krishna, 2005 (India) is assigned to the ceylonicus group.

Considering the geographical location of China, a very rich fauna of water mites should be expected. Previously, seventeen families have been reported from China (Jin, 1997; Smit, 2002; Guo & Jin, 2005): Eylaidae Leach, 1815, Limnocharidae Grube, 1859, Hydryphantidae Piersig, 1896, Hydrodromidae Viets, 1936, Hydrachnidae Leach, 1815, Sperchontidae Thor, 1900, Lebertiidae Thor, 1900, Oxidae Viets, 1926, Teutoniidae Koenike, 1910, Limnesiidae Thor, 1900, Hygrobatidae Koch, 1842, Unionicolidae Oudemans, 1909, Pionidae Thor, 1900, Mideopsidae Koenike, 1910, Arrenuridae Thor, 1900 and Pontarachnidae Koenike, 1910. The species described in this paper belongs to the subgenus Dartia Soar, 1917 in the genus Nilotonia Thor, 1905 of the family Anisitsiellidae Koenike, 1910, which increases the number of known water mite families in the Chinese fauna to eighteen.

Peniculus asinus, a new species of copepod parasitic on Sebastes (Pisces: Teleostei) off the Pacific coast of Canada is described and illustrated. The copepod is an unique member of its genus in that it possesses cephalothoracic holdfast processes. The discovery of a Peniculus with these processes is taken as evidence confirming the place of this genus in the family Pennellidae.

A new species of Tanaostigmodes (Hymenoptera: Chalcidoidea, Tanaostigmatidae) is described from China—Tanaostigmodes puerariae sp. nov. This is the first record of this family in China. This new species has potential as a biological control agent for control of kudzu, Pueraria lobate, in the U. S., because its preference for making leaf galls on kudzu. It was determined that the wasp has two generations per year, with the second generation overwintering as mature larvae in the gall on leaves that have dropped to the ground. Normally, only one wasp was found per gall, and a single kudzu leaf could have as many as 20 to 50 galls on its surface.
