Micropacteridae, a new family of Remipedia (Crustacea) from the Turks and Caicos Islands

Recent diving explorations of anchialine caves on the Turks and Caicos Islands yielded a rather small and slender new species of Remipedia. Micropacter yagerae n. gen., n. sp. is distinguished from all other species of nectiopod remipedes by a number of autapomorphic characters, including an oval body terminus with fused segments, unequal pairs of terminal claws on maxilla and maxilliped, an almost complete reduction of sternal bars and pleurotergites, molar processes with relatively few, but strong spines, and frontal filaments with bifurcate processes. Based on the unique combination of derived and primitive characters, we propose to erect a new family, Micropacteridae, for this new species and genus of Remipedia. Taxonomic diagnoses for the class Remipedia, order Nectiopoda (emended due to discovery that the maxilliped is 9-segmented), and for the families Speleonectidae and Godzilliidae are presented and discussed.     

Hanocladius,a new orthoclad genus from China (Diptera: Chironomidae)

Hanocladius longipes gen. nov., sp. nov. from Oriental China is described from the male imago. The long metatarsus, the very broad, scale-like virga and the conspicuously scalpellate acrostichals distinguish the genus from all of the known genera in Orthocladiinae.     

Laurentaeglyphea, a new genus for the second recent species of Glypheid recently discovered. (Crustacea Decapoda Glypheidae)

In 1975, a recent member of a large group of Crustacea Decapoda was described as Neoglyphea inopinata Forest & de Saint Laurent, until now only known as fossils and presumed extinct since the Eocene. The only known specimen had been collected in the Philippine waters, in 1908, at a depth of 200 m. During the next years, three oceanographical expeditions gave more adult specimens, allowing complete study of the species. From its morphology, it appeared that the status attributed to glypheids in the past in the classification of Decapoda Crustacea was quite erroneous. This group, until then considered as related to Palinurids (rock lobsters) was in fact much closer to Astacids (lobster, crayfish, etc.). In 1982, N. inopinata was recorded from the other side of Equator, from the Timor Sea. In October 2005, a second living species of glypheid was discovered southwest of New Caledonia. It was named Neoglyphea neocaledonica B. Richer de Forges, 2006. However, important and significant differences set apart the two species, especially the ornamentation of the cephalothorax, the conformation of the cephalic part and the proportions of epistom and thoracic appendages, being much more robust. It seems justified to establish, for the more recently described species, a new genus, Laurentaeglyphea, much closer to fossil forms.     

Kakaducaris glabra gen. nov., sp. nov., a new freshwater shrimp from the Kakadu National Park,Northern Territory,Australia, Crustacea: Decapoda: Palaemonidae with the designation of a new subfamily Kakaducaridinae

A new species of palaemonid shrimp from the Northern Territory Kakadu National Park is described and illustrated. Kakaducaris glabra, gen, nov., sp. nov., can not be satisfactorily referred to the described subfamilies of the Palaemonidae and a new subfamily Kakaducaridinae is designated (see addendum).     

New species and new records of pinnotherid crabs (Crustacea: Decapoda: Brachyura) from the Yellow Sea

Five species belonging to two genera of pinnotherid crabs are reported from the Yellow Sea. Two are new to science, namely: Sakaina glabra sp. nov. and Sakaina granulata sp. nov.; while three species are recorded for the first time from China: Pinnaxodes majorOrtmann, 1894, Pinnaxodes mutuensisSakai, 1939, and Sakaina japonicaSerène, 1964. Sakaina glabra can be easily distinguished from congeners by lacking a thick rim of pubescence along the anterolateral margin of the carapace. Sakaina granulata closely resembles S. asiatica (Sakai, 1933), but differs mainly in having a row of granule-like denticles along the anterolateral margin of its carapace.     

Genetic divergence and larval dispersal in two spider crabs (Crustacea: Decapoda)

The spider crabs Inachus dorsettensis (Pennant) and Hyas coarctatus Leach are widespread in subtidal areas of muddy sand or gravel around western Europe. Both species have a life cycle with an obligatory planktonic larval phase of several weeks, which might be expected to cause widespread larval dispersal and consequent genetic homogeneity over considerable distances. However, earlier work on both taxa has indicated differences in growth pattern between populations separated by tens of kilometres. This study was undertaken to determine whether these differences were purely environmental or whether, despite the short distances involved, differences may have a genetic basis. A study of gene frequencies, as indicated by allozymes in samples of adults collected off the Isle of Man (northern Irish Sea), indicates significant genetic differentiation between populations over a geographical distance of only about 40 km in both Inachus dorsettensis ( = 0.086 ± 0.048) and Hyas coarctatus ( = 0.023 ± 0.017). Variability measures differed between species, showing I. dorsettensis to have a mean number of alleles per locus of 2.5–2.6 and a range of gene diversity of 0.216–0.241, while H. coarctatus showed lower values of mean number of alleles (1.9–2.0) and a range of gene diversity from 0.122 to 0.124. Given the high expected larval mobility of the two species the results are most surprising. Possible explanations are discussed in relation to population discontinuities and patterns of larval drift.     

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.     

Ramicandelaber, a new genus of the Kickxellales, Zygomycetes

Ramicandelaber, a new genus of Zygomycetes is erected to accommodateRamicandelaber longisporus sp. nov. The fungus has hyphal septa with median plugs and forms homologous structures to sporocladia and pseudophialides. These characteristics suggest that it belongs to the Kickxellales, Zygomycetes.     

Hastatobythites arafurensis, a new bythitid genus and species from Australia (Bythitidae, Ophidiiformes)

A new genus and species of the subfamily Bythitinae (Bythitidae),Hastatobythites arafurensis, is described on the basis of two specimens from the Arafura Sea. The genus is unique in the subfamily in having two anteriorlydirected spines, one on the frontal and one on the mesethmoid. It is also distinguishable from all other genera in the subfamily by the following combination of characters: head scales absent; squamation on body incomplete; maxillary expanded posteriorly; no thin pore-bearing skin flap over opercle; opercle thin, weak, without distinct spine; jaw teeth conical; vomerine and palatine teeth present; developed gill rakers on 1 st arch 3; pelvic fins with 1 ray in each; pectoral peduncle elongated, with 16 rays; caudal fin rays 12; branchiostegal, rays 8; precaudal vertebrae 15, with tips of 6th to 12th neural spines truncated.     

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.     

Two new species of the genus Anisomysis (Anisomysis) (Crustacea,Mysida, Mysidae) from coral reef waters in Thailand

Two new species of Anisomysis Hansen, 1910 (Mysida, Mysidae), Anisomysis (Anisomysis) spinaintus sp. n. and Anisomysis (Anisomysis) phuketensis sp. n., from coral-reef waters in Thailand are described. Anisomysis (Anisomysis) spinaintus, collected in the Chaolao Beach, Chanthaburi Province, is distinguished from the closely allied species Anisomysis (Anisomysis) incisa Tattersall, 1936, and Anisomysis (Anisomysis) hawaiiensis Murano, 1995, by the presence of 6–9 spines on the apical cleft of telson, which are absent in the latter two allied species. The new species can also be distinguished from Anisomysis (Anisomysis) aikawai Ii, 1964, by the presence of a deep telson cleft and a large number of spines on the lateral margin of telson. Anisomysis (Anisomysis) phuketensis sp. n., collected in Ko Lon, Phuket, is distinguished from the allied species Anisomysis (Anisomysis) robustispina Panampunnayil, 1984, by having a short telson and a pair of long spines on the apical part of the telson. Keys to the subgenera and species of Anisomysis, including the two new species, are presented.     

A new genus and two new species of Phygadeuontini (Hymenoptera, Ichneumonidae, Cryptinae) from China

Carinityla Sheng & Sun gen. n., Carinityla punctulata Sheng & Sun sp. n. and Carinityla pilosa Sheng & Sun sp. n. belonging to the tribe Phygadeuontini of the subfamily Cryptinae (Hymenoptera, Ichneumonidae), collected from Jiangxi Province, China, are described. A key to the species of the new genus, Carinityla Sheng & Sun, gen. n., is provided and the genus is placed in Townes' key to genera of Endaseina.     

Study of the Nucleolar Organizer Regions in Palinurus elephas (Crustacea: Decapoda)

Using fluorescence in situ hybridization (FISH), chromomycin (CMA₃) staining and silver staining, we studied the nucleolar organizer regions in the spiny lobster Palinurus elephas in order to extend our knowledge on the karyology of this commercially important species. Multiple NORs have been detected by FISH, and CMA₃ showed a good correspondence between the localization of GC-rich heterochromatin and the ribosomal genes mapped by FISH. In contrast, the number of Ag-positive regions was higher than the number of FISH and CMA₃ signals, which may be explained by silver staining of the kinetochores. A variability in the number of FISH and CMA₃ signals has been detected in metaphases I and II which is probably due to the occurrence of rDNA cistrons on B chromosomes.     

Glaciella,a new genus of freshwater Canthocamptidae (Copepoda,Harpacticoida) from a glacier in Nepal,Himalayas

A new genus and new species of Canthocamptidae: Glaciella yalensis (Copepoda: Harpacticoida) from the surface of Yale Glacier, Nepal is described. This new species was collected from cryconite-pit on the surface of the glacier and is closely related to genus Maraenobiotus, but easily distinguishable from its species in the following: 1) segments and setae on endopodites of legs 2–4 in the male differing shape, 2) exopodites of male legs 3–4 with modified setae, 3) caudal seta in female absent. Body color of this copepod is red in live specimens.Contributions No. 86 Itako Hydrobiological Station, Ibaraki University.     

Turcichondrostoma,a new genus for the Leuciscidae (Teleostei: Cypriniformes) from Southwestern Anatolia

Turcichondrostoma, a new genus, from the Southwestern Anatolia is distinguished by having fewer gill rakers on first gill arch and morphologies of premaxilla and dentary bones. In addition, as a result of the phylogenetic analyses based on combine data set (mtDNA COI + Cytb) sequences (1706 bp.), Turcichondrostoma genus was recovered with high posterior probability value (BI PP:1.0) and strong-supported bootstrap value (ML BP: 100%) among the former Chondrostoma groups. Also, high K2P mean genetic distance values (more than 7.84%) differentiated genus Turcichondrostoma from the other genera of former Chondrostoma group. The results of both morphological-osteological and molecular analyses are congruent with each other. The results of this study revealed that the genus Turcichondrostoma is easily distinguished from the genera in Chondrostoma group.     

Paraimene tuberculata,a new genus and species of Isopoda (Sphaermomatidae) from Karachi,Pakistan
