Chirognathia dracula gen. et spec. nov. (Gnathostomulida) from the west coast of North America

A new gnathostomulid genus and species, Chirognathia dracula gen. et spec. nov., is described from intertidal surf grass (Phyllospadix) rhizomes on high-energy coasts of Vancouver Island (Canada) and Bodega Bay (California). The characteristics of the reproductive system place the new genus in Bursovaginoidea-Scleroperalia and features of the mouth parts (except for the absence of a jugum) assign it to the family Gnathostomulidae. Chirognathia nov. gen. is characterized by a delicate, transverse shield-shaped basal plate and by jaws with three tooth rows, of which the median appears as a bundle.     

A new genus and species of Metopiinae (Hymenoptera, Ichneumonidae) from Mexico

A new genus of Metopiinae, Ojuelos Khalaim, gen. n., with a single species, Ojuelos juachicus Khalaim & Ruíz-Cancino, sp. n., is described from Jalisco Province in central Mexico. Ojuelos belongs to the group of three genera (Cubus Townes & Townes, Colpotrochia Holmgren and Triclistus Förster) having a high lamella separating the antennal sockets and reaching the median ocellus (this lamella possesses a dorsal groove in it, just below the median ocellus), but differs from these genera primarily by 1) face and clypeus not convex in lateral view, 2) face separated from clypeus by a shallow transverse impression, 3) mandible with lower tooth very strongly reduced, 4) flagellomeres of antenna strongly transverse, and 5) dorsal carinae of propodeum reduced. A portion of the key to the genera of Metopiinae is provided to distinguish the new genus.

Morphology and Molecular Phylogeny of Two New Marine Euplotids,Pseudodiophrys nigricans n. g., n. sp., and Paradiophrys zhangi n. sp. (Ciliophora: Euplotida)

ABSTRACT. The morphology, infraciliature, and molecular phylogeny of Pseudodiophrys nigricans n. g., n. sp., and Paradiophrys zhangi n. sp., isolated from a sandy beach near Qingdao, China, were investigated. Pseudodiophrys is characterized by the Diophrys‐like ciliature pattern, but having only a single, reduced undulating membrane. Pseudodiophrys nigricans, the type species by monotypy, is described from live and silver‐impregnated specimens. Paradiophrys zhangi is similar to the type species Paradiophrys irmgard but can be recognized by its border body and the number (7 vs. 8–10) and arrangement (in rows vs. sparsely distributed) of the frontoventral cirri. Small subunit (SSU) rRNA gene sequence data support the validity of both species. Phylogenetic analyses based on the SSU rRNA gene sequence data currently available for uronychiids and other related taxa indicate that P. nigricans is most closely related to Diophrys scutum and Diophrys apoligothrix, while P. zhangi clusters most closely with Apodiophrys ovalis within a clade that also includes two other Paradiophrys species.     

The freshwater crab fauna (Crustacea: Brachyura) of the Philippines. V. On a new genus and species of potamid from Palawan island, Philippines

A new genus and new species of terrestrial potamid crab ( Carpomon pomulum) is described from the island of Palawan in the Philippines. This new genus can easily be distinguished from all other Philippine potamids in its smooth and inflated carapace, no trace of an epibranchial tooth, extremely low postorbital cristae, and stout and twisted male first gonopod. This revised version was published online in July 2006 with corrections to the Cover Date.     

Taxonomic revision of the subfamily Toradjiinae (Crustacea: Oniscidea: Scleropactidae)

In the present revision four genera and 32 species are recognized. One genus, Paratoradjia , and 17 species, namely Adinda malaccensis, A. sumatrana, A. palniensis, A. carli, A. nilgiriensis, A. lobata, A. triangulifera, A. rudeli, A. lamellata, Protoradjia paeninsulae, P. insularis, P. montana, P. pilosa, Paratoradjia beroni, P. vietnamensis, P. sulcata and Toradjia hirsute , are described as new. The neotype of Toradjia cephalka and lectotypes of Adinda weberi, Protoradjia jacobsoni, Toradjia gorgona and T. celebensis are established. Adinda cahgarii is considered to be a junior synonym of Adinda weberi , and A. conglobator , a species inquirenda. Toradjia dollfusi is transferred to the genus Adinda , and T. indosinensis to Paratoradjia. The characters of the group and its taxonomic position within the Oniscidea are discussed: it is transferred from the Eubelidae to the Scleropactidae, of which it constitutes a separate subfamily, the Toradjiinae. A map and comments on the distribution of genera and species are included.     

Cytisus purgans auct(Leguminosae-Papilionoideae comprises four distinct species)

Based on a study of the morphology and stem anatomy of a broad sample of specimens attributed to Cytisus purgans auct. non Cytisus purgans (L.) Boiss. four species are recognized. Two species are non-spiny: Cytisus oromediterraneus Rivas Martínez et at. is a widely distributed taxon ranging from central France to north-central Spain and Portugal, and C. galianoi Talavera & Gibbs, sp. nov., which is restricted to schistose sierras in south-east Spain. C. oromediterraneus has 8-ribbed stems and 2-ribbed stipular organs, whilst C. galianoi has 10-ribbed stems and 3-ribbed stipular organs. Of two spiny species, Cytisus balansae (Boiss.) Ball wkh 10-ribbed stems, occurs in calcareous mountain areas, 1800–2500 m in Algeria and southern Morocco, whilst C. valdesii Talavera & Gibbs, nom. nov. with 13-ribbed stems, occurs in die High and Middle Atlas of Morocco. Both north African species have 3-ribbed stipular organs.     

A new goby (Teleostei: Gobiidae) from the South China Sea and its significance for gobioid classification

A new genus and species of gobiid fish, Egglestonichthys Patriciae , is described from the South China Sea. Certain features of the modified head lateral-line system resemble those seen in eleotrine genera with 'transverse' suborbital sensory papillae, but the skeleton of the new goby is essentially gobiine. Aspects of the lateral-line system indicate closest relationship with genera from both the IndoPacific area ( Callogobius complex, Psilogobius, Stonogobiops ) and the New World ( Microgobius ). Wider affinities with other gobiine and gobionelline genera are discussed. Discrepancies between arrangements based predominantly on lateral-line characters and on osteology are noted and their implications considered for future classification of the gobioid fishes.
