A new species of the subterranean genus Oodinotrechus Uéno, 1998, from northern Guangxi,China, with additions to the generic diagnosis (Coleoptera: Carabidae: Trechinae)

A new eyeless species, Oodinotrechus liyoubangi n. sp, is described from northern Guangxi. All specimens of this interesting species were collected in three limestone caves in Mulun National Nature Reserve of northern Guangxi, southern China. It is the second species for the genus Oodinotrechus Uéno, 1998, distinguished from the type species O. kishimotoi Uéno, 1998 by its visible scutellum and pronotal structure. Several additional diagnostic characters for the genus and a geographical distribution map for both known species are also provided.

Four species of Caligus Müller, 1785 (Copepoda,Siphonostomatoida, Caligidae) parasitic on marine fishes of Taiwan

Four species of Caligus, with two new species, are reported from five species of marine fishes of Taiwan. They are: Caligus arii Bassett‐Smith, 1898 Bassett‐Smith, P. W. 1898. Further new parasitic copepods found on fish in the Indo‐tropical region.. Annals and Magazine of Natural History (Series 7), 2: 77–98.

Caligus dasyaticus sp. nov. and Caligus dussumieri sp. nov., (Copepoda) parasitic on Bombay fishes.. Journal of the University of Bombay, 25: 16–22.  [Google Scholar] on the body surface of Dasyatis navarrae (Steindachner), Caligus dactylus n. sp. on the gill filaments of Dactyloptera peterseni (Nyström), and Caligus lutjani n. sp. in the oral/gill cavities of Lutjanus argentimaculaltus (Forsskål) and Lutjanus bohar (Forsskål). Both C. arii and C. dasyaticus are reported for the first time from Taiwan. Caligus dactylus differs from its congeners by the possession of the following combination of features: large myxal process on the maxilliped; a pair of parallel tines on the sternal furca with truncate tip; simple elements (without accessory process) at the tip of leg 1 exopod; and an armature formula of I‐0; I,III on leg 4. Caligus lutjani is distinguished by carrying a two‐segmented abdomen; a pair of diverged tines on the sternal furca with acute tip; an accessory process on the middle two of the terminal four elements on the exopod of leg 1; and a bipectinate, spiniform process on the exopod of leg 4 at the insertion of each of the five outer spines.

Revision of Pilargis de Saint‐Joseph, 1899 (Annelida,Polychaeta, Pilargidae)

Pilargis de Saint‐Joseph, 1899 includes seven species and one subspecies: P. berkeleyae Monro, 1933 Monro, C. C. A. 1933.

Two species (P. verrucosa and P. berkeleyae) have been recorded from widespread localities. However, no comparison with type material has been done, and there might be some different forms under the same name. We have reviewed all the available type material in order to clarify the taxonomy of this group. A critical analysis of morphological features and a standardization of their structure and variability have been attempted. Six species are redescribed, one species is characterized after published accounts, and one subspecies is elevated to species. Four are described as new: Pilargis angeli n. sp., P. cholae n. sp., P. rozbaczyloi n. sp., and P. wolfi n. sp. Three others based on damaged material are briefly characterized. A key for Pilargis species is included.     

Plovers breeding in the highlands of Jalisco, Aguascalientes, Zacatecas, and San Luis Potosí, central Mexico

From April to July 2008, we surveyed for breeding plovers at 32 sites in the semiarid highlands of Jalisco, Aguascalientes, Zacatecas, and San Luis Potosí, in the Central Mexican High Plateau. We documented evidence or presumption of breeding Snowy Plovers ( Charadrius alexandrinus ) at 3 sites, Killdeer ( C. vociferus ) at 15 sites, and Mountain Plovers ( C. montanus ) at 1 site. Our surveys showed that the region is important breeding ground for only the Killdeer. We documented an apparent breeding range extension of the Mountain Plover to slightly more than 200 km south of its previously known breeding range.     

First documentation of Salmincola californiensis in Lake Tahoe, CA–NV, USA

Salmincola californiensis is a parasitic copepod in the Lernaeopodidae family that commonly parasitizes salmonid fishes ( Oncorhynchus spp.) by attaching near the fins and on gill filaments. Historically their distribution was limited to streams that emptied into the Pacific Ocean. During the summer of 2006, several rainbow trout ( Oncorhynchus mykiss ) captured in Lake Tahoe were infested with S. californiensis . This is the first known record of S. californiensis in Lake Tahoe.     

Another inordinate fondness†: diversity of the tanaidacean fauna of Australia,with description of three new taxa

The shallow-water tanaidacean fauna of the Bass Strait has been the subject of recent intensive studies. The present paper extends this work into the deeper waters of the region, describing two new species and one new genus. The new species of the genus Paradoxapseudes has a combination of three maxillule palp setae, no plumose setae on the basis of pereopod 1 nor proximal serration on the antennal peduncle. The second species represents a new genus of the family Anarthruridae, having six marginal setae on the third maxilliped palp article and spines on the merus and carpus of the anterior pereopods. The high diversity of Tanaidacea in Australian waters is discussed. In particular, we conclude that Australian coasts suffer a diversity of immigration routes, have sufficient marine longevity, and afford such a diversity of available niches to have allowed multiple colonization and subsequent allopatric speciation of Tanaidacea. http://www.zoobank.org/urn:lsid:zoobank.org:pub:EE309A5A-E06D-416F-95BD-4C8D0D2BEB97     

Rediscovered population of Mexican Plateau spotted whiptail lizard, Aspidoscelis septemvittata , from México, D.F.

Multiple surveys carried out by herpetologists in México, D.F., during the 1980s failed to find specimens of Aspidoscelis septemvitatta (Squamata: Teiidae). However, 10 specimens were recently collected to the east of México, D.F., inside a protected area, Sierra de Santa Catarina. The Sierra de Santa Catarina has been heavily modified by human activity and habitation. Morphological and natural history information about the specimens are presented, as well as notes on locality.     

Rediscovery of the Neotoma population on Datil [Turner] Island, Sonora, México

On Datil [Turner] Island in the Gulf of California, we rediscovered a population of Neotoma varia, previously thought to be extinct. We captured 5 specimens: 1 was kept as a voucher, and 4 were examined and released. Analysis of previous surveys indicates that N. varia is not common on the island and occupies a very restricted range. Recolectamos especímenes de Neotoma varia de la Isla Dátil en el Golfo de California, una población anteriormente considerada ya extinta. De los cinco especímenes que recolectamos, cuatro se pusieron en libertad. El análisis de muestreos previos indica que N. varia no es común en la isla y que tiene una distribución muy limitada.     

Comparative demography of the high-altitude lizard, Sceloporus grammicus (Phrynosomatidae), on the Iztaccihuatl Volcano, Puebla, México

Population density, reproduction, and survivorship were compared between 2 populations of Sceloporus grammicus occurring at different altitudes (3700 m and 4400 m) on the eastern slopes of Iztaccihuatl Volcano, Puebla, México. Lizards in both populations matured at the same age (14-15 mon) and size (39-42 mm SLV). Population density was slightly greater at high altitude (131-163 per ha) than at low altitude (52-83 per ha). Survivorship and R o were higher at the low-altitude areas, but in general there were no significant demographic variations between altitudes that have been reported in lizard population at higher latitudes. Studies of lower-elevation populations might reveal some differences because previous studies indicated that litter size increases at lower altitudes, although they do not differ between our 3700 m and 4400 m populations.     

A study of Platyplectrus Ferrière (Hymenoptera: Eulophidae) in mainland China

This paper reviews the Chinese species of Platyplectrus Ferrière. Twelve valid species are recognized from mainland China and a key to species is provided. Trichoplectrus Erdös (1951 Erdös, J, 1951. "Eulophidae novae. Acta Biologica". 1951, Academiae Scientiarum Hungaricae, 2(1–3), 169–237. [Google Scholar]) is newly synonymized with Metaplectrus Ferrière (1941 Ferrière, C, 1941. New species of Euplectrini (Hym. Chalcidoidea) from Europe, Africa and Asia, Bulletin of Entomological Research 32 (1941), pp. 17–48.[Crossref] , [Google Scholar]) and three new combinations are proposed: Metaplectrus szepligetii (Erdös) from Platyplectrus, Platyplectrus bussy (Crawford) from Euplectrus and P. politus (Lin) from Metaplectrus. Four species of Platyplectrus were known previously from China: P. politus (Lin), P. odontogaster (Lin), P. papillata Lin and P. medius Zhu and Huang. Six species, P. bussyi (Crawford), P. laeviscuta (Thomson), P. natadae Ferrière, P. orthocraspedae Ferrière, P. pannonica (Erdös) and P. viridiceps (Ferrière) are newly recorded from China and re-described. Five new species, P. pulcher, P. setulosus, P. peculiaris, P. obtusiclavatus and P. variflagellum are described and compared with related species. Several species are also newly recorded from other regions: P. orthocraspedae Ferrière from the Afrotropical region, P. bussyi (Crawford) and P. laeviscuta (Thomson) from the Australian/Pacific region, P. laeviscuta (Thomson) from the Oriental region and P. viridiceps from the Palearctic region.     

Comparison of zooplankton community structure between impacted and non-impacted areas of Paranaguá Bay Estuarine Complex,south Brazil

We analysed the seasonal distribution of the zooplankton community in an anthropogenically impacted area (Paranaguá Bay) and a non-impacted area (Laranjeiras Bay) of the Paranaguá Bay Estuarine Complex. Large phytoplankton (> 50 μm) and zooplankton were collected every two months, between August 2003 and June 2004. The phytoplankton community was numerically dominated by diatoms (78%) and dinoflagellates (19%). Zooplankton abundance varied between 670 and 100,716 individuals m^–3, with a dominance of copepods, mainly the calanoids Acartia lilljeborgii, Acartia tonsa and Pseudodiaptomus acutus. A clear seasonal pattern was observed: copepods were significantly more abundant during the rainy than in the dry season. Significant differences in abundance between the two bays were detected only for cirripede larvae, which were more abundant in Paranaguá Bay. This lack of difference between the two areas was probably a consequence of the water circulation along the estuary, which may have diluted and dispersed the pollutants from Paranaguá Bay to other areas of the estuary.     

Extension of southern range and new specimens of the western gray squirrel, Sciurus griseus anthonyi (Mammalia: Sciuridae), in Baja California, México

We documented a southern range extension and new specimens of western gray squirrel ( Sciurus griseus anthonyi ) for the state of Baja California, México. The most recent specimen was collected in the town Cataviña and represents the southernmost record for the species and subspecies. Repeated observations of individuals in this new location suggest the presence of a marginal population in Mediterranean chaparral–desert scrub transition vegetation. Documentamos la extension de ámbito más sureño y nuevos especímenes de a ardilla gris occidental ( Sciurus griseus anthonyi ) para el Estado de Baja California, México. El espécimen más reciente fue recolectado en el poblado de Cataviña y representa el registro más sureño para la especie y subespecie. Observaciones repetidas de individuos en esta última localidad sureña sugiere la presencia de una población marginal en vegetación de transición de chaparral mediterráneo–matorral desértico.
