A New Species

In 1950 work was started in New Brunswick to obtain information on the biology, control, and damage caused by the arborvitae leaf miners. At that time all damage was attributed to the arborvitae leaf miner, Argyresthia thiella (Pack.). After the first season's work four species were recognized. Adults submitted to the Systematic Unit, Entomology Division, Ottawa, were identified as Argyresthia thuiella (Pack.), A. freyella Wlshm., Recurvaria thujaella Kft., and a new species of Argyresthia later described by Brower (1) as aureoargentella. With the exception of A. thuiella, insufficient material was available for complete morphological studies, so work was based on finding suitable characters to separate the species in the late larval, pupal, and adult stages.

A New Species

Cryptobenthic fauna investigations are highly relevant at studying biodiversity of regions. Studies of the species composition of Gobiesocidae family were carried out in order to clarify ichthyofauna of different regions, and a new species for the Black Sea coastal zone of Crimea was found. Information about its morphology, biology, behavior and other characteristics is very important because of weak study and indeterminate taxonomic status of this species. As a result of morphological studies of the Crimean specimens no significant difference with the type of the Atlantic-Mediterranean populations has been proven. Naturalization of small-headed clingfish in coastal waters of Crimea has been confirmed and some population characteristics, such as a length-weight relationship, have been described. Peculiarities of habitat which which small-headed clingfish prefers and features of localization, enabling competitiveness have been identified. Identification keys were compiled and are given in the paper.

A New Species

Integrated molecular and morphological studies of newly collected and curated specimens of the genus Caridina from the Atherton Tablelands, Wet Tropics World Heritage Area in north–eastern Queensland, Australia indicated the presence of an undescribed species belonging to the Caridina zebra Short 1993 complex. This species is somewhat intermediate, although distinct on the basis of molecular data and morphology, from two known sympatric species, Caridina zebra and C. confusa Choy & Marshall 1997, and an allopatric species, C. spinula Choy & Marshall 1997, from the Cape York Peninsula, about 500 km north. It is described here as a new species, C. malanda sp. nov., and compared with similar congeners. A key for the identification of the species, as well as notes on its distribution, ecology, and conservation, are provided.

A New Species

A new species, Selaginella coriaceifolia, is described and illustrated from central Vietnam. The new species can be distinguished from other species in Asia by its habit epilithic, main stem nearly isotomously branched, leaves strongly leathery, ventral leaves imbricate on stem and branch, dorsal leaves with reflexed arista at apex, and sporophylls nearly monomorphic. Molecular and morphological studies of the new species and its allies in S. subg. Heterostachys Baker sect. Heterostachys (Baker) Li Bing Zhang & X.M.Zhou are conducted.

Microcerotermes Silvestri is a cosmopolitan genus and is distributed in all zoogeographical regions, with the exception of the Nearctic. During the study of Iranian termite fauna, specimens of Microcerotermes were collected from Shahroud, Iran. Morphological studies indicated that specimens belonged to a new species. This species comes closest to Microcerotermes varaminicus Ghayourfar, but soldiers differ in possessing darker head-capsule and distinct postclypeus demarcated from frons.

A new tardigrade species, Diphascon (Diphascon)burti, is described from lichens and mosses in New Brunswick, Canada. It differs from other species of the genus Diphascon by the presence of two macroplacoids, a large flared septulum, and a transverse pseudoseptulum. A pseudoseptulum has been reported previously in only one species from Antarctica. The description of D. burti increases the number of Diphascon species recorded from Canada to 15.

Sixteen sponge species were recorded from Little Letite Passage, an area of highvelocity tidal currents located in the Bay of Fundy near Deer Island, New Brunswick, Canada. Of these 16 species, four species (Myxilla fimbriata, Hymeniacidon heliophila, Hemigellius sp. aff. flagellifer, and Crella rosea) have not previously been recorded from the Bay of Fundy. One new species, Hymedesmia canadensis, is described, based on the presence of a second peculiar chelate microsclere added to the spicule armament.

A New Species

A new species of Paraseison (Rotifera: Seisonacea: Seisonidae) is described from the eastern Pacific Ocean off the coast of California. Female and male specimens of the new species were attached inside the carapace of the leptostracan crustacean Nebalia hessleri, collected at 19 m depth in La Jolla Canyon. This recording represents the first properly identified and described species of Seisonacea for the American coasts. It is furthermore the second known species of the genus Paraseison, which until now included the species P. annulatus only, reported for the Mediterranean Sea and European west Atlantic coast. The new species was diagnosed mostly by its species-specific trophi morphology and in particular by the shape of its fulcrum. Paraseison kisfaludyi sp. nov. is the fourth described species of the order Seisonacea, which accommodates also Seison nebaliae and the recently described S. africanus, all of which live attached to species in the leptostracan genus Nebalia. Even though the Seisonacea are placed in a crucial position within the phylum and may constitute the link between rotifers and other platyzoans, this taxon has in many respects been neglected in morphological studies. Herein we provide new information on the group's taxonomy, morphology and distribution, which will be useful for future phylogenetic and zoogeographical studies.
