We report the presence of the competent vector for Leishmania spp, Migonemyia migonei, and the Evandromyia cortelezzii-sallesi complex south of its known distribution in the central temperate region of Argentina, in the province of Córdoba. The persistence of this phlebotomine in the northern border of the province, its association with a case of cutaneous leishmaniasis, and the new record in the outskirts of the city of Córdoba, the second most populated in the country, strengthens the need for regular vector surveillance and a case detection-sensitive health system in vulnerable regions, even in temperate climates.

Se presentan las propiedades eléctricas del compuesto Cu3BiS3 depositado por co-evaporación. Este es un nuevo compuesto que puede tener propiedades adecuadas para ser utilizado como capa absorbente en celdas solares. Las muestras fueron caracterizadas a través de medidas de efecto Hall y fotovoltaje superficial transiente (SPV). A través de medidas de efecto Hall se encontró que la concentración de portadores de carga n es del orden de 1016 cm-3 independiente de la relación de masas de Cu/Bi. También se encontró que la movilidad de este compuesto (μ del orden de 4 cm2V -1s-1) varía de acuerdo con los mecanismos de transporte que la gobiernan en dependencia con la temperatura. A partir de las medidas de SPV se encontró alta densidad de defectos superficiales, defectos que son pasivados al superponer una capa buffer sobre el compuesto Cu3BiS3.

Obstetric documentation processes may influence the clinical, behavioural, and psychological outcomes of pregnancy, although recent alterations to integrate obstetric documentation with pregnancy handheld records have been unsuccessful. Woman-held records as a companion to usual obstetric documentation have the potential to improve pregnancy-related health behaviours with a demonstrated association with maternal and infant health outcomes, and recommendations for their format and content are provided.

Yelsemia lowrieana sp . nov. (Ustilaginomycetes) is described and illustrated from Byblis rorida collected in northwestern Western Australia. Infected plants had galls filled with spores on stems and pedicels. The spores were unusual in that each could be separated from a dark outer spore wall. This is the first record of a smut fungus on the dicotyledonous host family Byblidaceae.

Bactrocera (Bactrocera) speewahensis Fay & Hancock sp. n. is described from northern Queensland and B. (B.) torresiae Huxham & Hancock sp. n. is described from Boigu, Saibai and Dauan islands in Torres Strait and southern Papua New Guinea. Bactrocera (B.) nigrovittata Drew is newly recorded from Australia. All records are of male flies responding to chemical lures.

The authors report the record of Cyclops singularis collected from Peasemoor Piece, a seasonal pond on the outskirts of Oxford. This preliminary note is to alert others to the possibility that C singularis may occur in collections from seasonal ponds in the UK. The recent record of this species in Belgium (Alekseev et al. 2002) indicates that this species is not restricted to its type locality.

EXTRACT (SEE PDF FOR FULL ABSTRACT): Pluvial Lake Estancia in central New Mexico experienced large and rapid fluctuations in surface area and elevation during the build-up to and termination of the last glacial maximum (LGM). Due to continuous groundwater discharge, a minimum pool covering about 400 square kilometers was maintained in the central basin until about 12,000 years ago, ensuring a continuous depositional sequence even during low stands of the lake. ... The sensitive response to fluctuations in climate by several independent proxies at Estancia show that transport of Pacific moisture over western North America changed dramatically during the last Ice Age, perhaps comparable to the large and rapid changes in climate documented from high-latitude ice and North Atlantic marine sediments for the LCM and its transitions.

EXTRACT (SEE PDF FOR FULL ABSTRACT): Exposed sediments of Late Pleistocene Lake Estancia contain a high resolution record of regional climate variability for the period about 12,000 to 32,000 years. A detailed rock-magnetic study is being performed on this well-dated, well-preserved sedimentary sequence to determine how the magnetic signature of sediments responded to regional climate change.

One male and one female of Zozymodes cavipes (Dana, 1852) have revently been collected from the rocky shores near Karachi; the species is widely distributed in the Indo-Pacific region. It is, however, being reported for the first time from the pakistani coast of the northern Arabian Sea and thus fills the gap in the known distribution of the species. The pakistani material is housed in the Marine Reference Collection Centre, University of Karachi. The specimens are briefly descibed below. Only restricted synonym is given.

Previously an asteroid starfish Astropecten indicus has been described by Tahera (1996), and another species of the genus Astropecten i.e. A. polyacanthus Muller and Troschel, 1842 has been collected from the subtidal region of a sandy shore of Clifton (24°47'42"N 66°59'6"E), Karachi. The latter species is here reported for the first time from the Pakistan coast of the northern Arabian Sea and fills the gap in the known distribution. The species is briefly described and illustrated.

1998 年在西藏墨脱县海拔1000 m 左右地方采到成年雌性环蛇1 号, 系我国新纪录。该蛇全长/ 尾长(mm) 1095/ 112 (尾尖断) 。通身背面黑褐色, 后3/ 4 有由背鳞白色点斑缀成的窄横纹约40 个; 腹面浅黑 色, 每隔3 或4 枚腹鳞有不规则的黄白色横斑。尾背有少数不完整的白色纹, 但尾腹面有7 条很明显的横斑。头 部斑纹与M. Smith (1943 : 410) 描述一致, 可能由于蛇龄较老而不清晰。背鳞通身15 行, 脊鳞略扩大; 腹鳞 233 , 尾下鳞35 (略低于文献记载的44~51 , 可能与尾尖断有关) , 除前端第三、四两枚成单外, 其余均成对。 没有颊鳞; 眶前鳞1 , 眶后鳞2 ; 颞鳞1 + 2 ; 上唇鳞7 (22223 式) ; 下唇鳞7 , 第一对在颏鳞后彼此相接, 前4 对 接前颔片; 前颔片大于后颔片, 后者后半介一小鳞。检查一侧, 除前沟牙及其预备牙外, 没有发现其他上颌齿。

Six species belonging to two families of Hemichordata have previously been recorded in Chinese waters. This paper records the discovery and description of a new species of the genus Glandiceps found in Jiaozhou Bay, Qingdao, Shandong Province, named Glandiceps qingdaoensis. The new species has a long proboscis with dorsal and ventral grooves, a stomochord with a long vermiform process, a proboscis cavity with a dorsal median, right and left glomeruli, right and left glomeruli very large and encircling the stomochord, a proboscis skeleton in the cavity extends into the median posterior of the collar, a well-developed dorsal ventral muscular septum in the proboscis cavity dividing the cavity completely into two separate parts. The collar cord is without giant nerve roots. The trunk with four distinct regions that can be recognized externally: branchial-genital region, genital region, hepatic region, and intestinal region. The dorsal pharynx is large and the gill pores are small. The tongue bars are encircled by vesicles, and the first gonad commences at the level of the second or third gill slit.

A new species, Axianassa sinica, from the Beibu Gulf (Gulf of Tonkin), northern South China Sea, is described and illustrated. The new species is readily distinguished from A. australis Rodrigues & Shimizu, 1992, by its acute rostrum, merus of pereopod 1 with a tooth distally on lower margin and an elongated telson.
