A new species of the genus Nihonotrypaea Manning & Tamaki, 1998, Nihonotrypaeahainanensis sp. n., collected from the South China Sea, is described and illustrated. It is distinguishable from Nihonotrypaeaharmandi (Bouvier, 1901), Nihonotrypaeajaponica (Ortmann, 1891), Nihonotrypaeathermophila Lin, Komai & Chan, 2007 and Nihonotrypaeamakarovi Martin, 2013 by having the elongated carpus of the ma...

We describe an isolated archosauriform tooth from the Upper Triassic Painted Desert Member of the Petrified Forest Formation in Zion National Park in southwestern Utah. This tooth is relatively low (mesiodistally as long as baso-apically tall), bulbous and asymmetrical in occlusal view, and has denticles that are oblique to the tooth crown. The base of the tooth is also slightly expanded relati...

During a survey of soil nematodes in Iran, three species of predatory nematodes, including a new species of the genus Mylonchulus Cobb, 1916 were recovered. Mylonchulus kermaniensis sp. n. is characterised by its body length (1.2-1.4 mm), six rows of rasp-like denticles, the sixth line consisting of four denticles, female tail slightly sigmoid, sharply bent ventrad with digitate posterior porti...

OBJECTIVE To assess the efficacy and safety of a "mini-perc" technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. MATERIALS AND METHODS From July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the "mini-perc" technique of percutaneous nephr...

A new Dipterus−like lungfish, Harajicadipterus youngi, is described from the Givetian (Middle Devonian) Harajica Sand− stone Member of central Australia. The material is comprised of five specimens representing the skull roof, orbital bones, tooth plates, operculo−gular bones, a partial pectoral girdle, centra and scales. Harajicadipterus can be distinguished from other dipnoans by its long pos...

Two new species of Neotanais Beddard, 1886 are described from the Korea Deep Ocean Study (KODOS) area in the Clarion-Clipperton Fracture Zone, based on the collections performed on board R/V Onnuri from a depth of 5180 m. Neotanais triqueturus n. sp. is similar to the 'pfaffi group' characterized by pereonites with a swollen distolateral margin, pleonites with mid-ventral spurs and tapered late...

The wild-type functions of the Wnt family of genes are still little understood (for review see Nusse and Varmus, Cell 69, 1073-1087, 1992). In Drosophila, the wingless (D-Wnt-1) protein is expressed in segmental stripes: its absence leads to a complete failure of segmentation, loss of engrailed expression and lack of pattern in the cuticle. A predominating hypothesis is that the spatial distrib...

Certain Drosophila embryonic epidermal cells construct actin-based protrusions, called denticles, which exhibit stereotyped, column-specific differences in size, density and hook orientation. This precise denticle pattern is conserved throughout all drosophilids yet studied, and screening for mutations that affect this pattern has been used to identify genes involved in development and signalin...

Tityus gonzalespongai n. sp. is a species endemic to the high mountains of Anzoátegui State, Venezuela. It is found between 1,600 and 2,200 m in “La Laguna” mountain. Its habitat includes the area of “Bosque Húmedo Montano Bajo” with the type of vegetation of “Bosque Ombrófilo Montano Siempreverde” (“Bosques Nublados Costeros” that includes the “Subpáramos Arbustivos”). It is distinguished from...

A new species of the genus Lathriopyga Caroli, from the Republic of Moldova is described and figured. It differs from its closest relative, Lathriopyga bulgarica Smolis, Skarżyński & Pomorski, by the presence of 3+3 chaetae Di on Abd. V, Di1 as a long macrochaeta, Di2, Di3 as short macrochaetae, presence of three chaetae Oc on head and the form of mandible (with 6–7 denticles appearing as a fri...
