A laboratory study was carried out to evaluate the repellent efficacy of a methanol-leaf extract of Ethiopian traditionally used insect repellent plant viz., Lomi sar [vernacular name (local native language, Amharic); Cymbopogon citratus (DC) Stapf. (Poaceae)] against Anopheles arabiensis at four different concentrations viz., 1.0, 1.5, 2.0, and 2.5 mg/cm2. The percentage protection in relation to the dose method was performed. C. citratus extract has shown various degrees of repellency impact against A. arabiensis. It provided the maximum total percentage protection of 78.83% at 2.5 mg/cm2 and followed 68.06% at 2.0 mg/cm2 for 12 h. All four tested concentrations of C. citratus extract offered significant protection and Student's t test results shows statistically significant (p value=0.001) [1.0 mg/cm2 (t=22.89; df=4); 1.5 mg/cm2 (t=24.03; df=4); 2.0 mg/cm2 (t=36.92; df=4); 2.5 mg/cm2 (t=22.31; df=4)] difference between treated and control groups. The result suggests that it could serve as a potent insect repellent against vectors of disease. Globally, C. citratus is renowned for its therapeutic values. Above and beyond, due to its user- as well as environmental-friendly nature, it should be promoted among the marginalized populations in order to reduce man-vector contact. In addition, this appropriate strategy affords the opportunity to minimize chemical repellent usage and the risks associated with adverse side effects. At the end of the day, traditionally used plant-based insect repellents could be viable safer alternative sources for chemical insect repellents. © Springer-Verlag 2010.

The Western Ghats, India, present a series of challenges and opportunities for novel approaches to conservation. Running parallel to the coast of the Indian Peninsula, the Ghats represent the western edge of the Deccan Plateau and traverse 1400km over six states, giving rise to rivers that drain over a third of the country. A global biodiversity hotspot with varied topography housing diverse ecological niches, the Western Ghats present significant challenges to, and opportunities for, conservation. Dense human habitation near river systems and dependence on freshwater resources for livelihoods make it difficult to establish protected areas. Freshwater fishes in this region account for c. 40% of the freshwater fishes in India and around 189 species are endemic to the Western Ghats. All the usual threats to the fishes and their habitats are present, and the freshwater fishes of the Western Ghats are of great social and economic importance to the local community. Zoos, aquariums and the general public can play a role in conservation efforts through education and research. Utilizing traditional customs already in place, such as water bodies in the vicinity of temples where no fishing occurs, in conjunction with ecotourism and more modern technologies, such as live gene banks and cryopreservation, may ease the burden on the freshwater habitats and fishes in the region. © 2013 The Zoological Society of London.

abs The published work making available the nomen Leptobrachium nokrekensis Mathew and Sen, "2009" 2010, bearing a date of publication of 2009, is shown to have been published on 3 June 2010. The taxon is further shown to be a member of the genus Leptolalax Dubois, 1983. Leptolalax nokrekensis (Mathew and Sen, 2010) is compared with the three known congeners from India (L. khasiorum, L. lateralis, and L. tamdil). A table of comparative data for all recognized species of Leptolalax is presented. © 2011 by The Herpetological Society of Japan.

The study of publications and of museum specimens allows unequivocal identification of the type specimens of Pyxicephalus khasianus Anderson, 1871. These specimens were collected by Thomas Jerdon at the same time as the type specimens of Rana laticeps Boulenger, 1882 and belong to the same biological species. We describe and figure the lectotypes of Pyxicephalus khasianus and of Rana laticeps and give measurements of the other specimens seen by the authors of the original descriptions of both taxa. Thus, both names having been regularly used in literature, the valid name of this species is Limnonectes khasianus (Anderson, 1871), and Rana laticeps Boulenger, 1882 is its junior subjective synonym.

Methanol leaf extracts of two Ethiopian traditional medicinal plants viz., Lomisar [vernacular name (local native language, Amharic); Cymbopogon citratus (DC) Stapf. (Poaceae)] and Bisana [vernacular name (local native language, Amharic); Croton macrostachyus Del. (Euphorbiaceae)] were screened for larvicidal activity against late third instar larvae of Anopheles arabiensis Patton, a potent malaria vector in Ethiopia. The larval mortality was observed 24 h of post treatment. Both plant extracts demonstrated varying degrees of larvicidal activity against Anopheles arabiensis. Cymbopogon citratus extract has exhibited potent larvicidal activity than Croton macrostachyus at lower concentrations. The LC50 and LC90 values of Cymbopogon citratus were 74.02 and 158.20 ppm, respectively. From this data, a chi-square value 2.760 is significant at the P<0.05 level. While, the LC50 and LC90 values of Croton macrostachyus were 89.25 and 224.98 ppm, respectively and the chi-square value 1.035 is significant at the P<0.05 level. The present investigation establishes that these plant extracts could serve as potent mosquito larvicidal agents against Anopheles arabiensis. However, their mode of actions and larvicidal efficiency under the field conditions should be scrutinized and determined in the near future.

Schistura paucireticulata, new species, is described from the Tuirial River in Mizoram, India. It is distinguished from its congeners by a combination of characters: 8-9 brown bars on the body, bars in front of the dorsal fin divided into 2-3 small bars forming a reticulations; basicaudal bar black, dissociated; dorsal fin spotted, with 4 simple and 81/2 branched rays; anal fin with 3 simple and 6 branched rays; lateral line complete; caudal fin deeply emarginated with 9+8 branched rays; well developed axillary pelvic lobe; and caudal fin with numerous black spots arranged in 3-4 bars. © 2013 Magnolia Press.

Psilorhynchus rowleyi Hora and Misra 1941 known from the Chindwin-Irrawaddy drainage, formerly treated as a subspecies of the Ganga-Brahmaputra drainage species, Psilorhynchus homaloptera Hora and Mukerji 1935, is redescribed here based on newly collected materials and two syntypes in the Zoological Survey of India. It differs from the latter in having a larger eye (21.7-31.5 % head length vs. 13.4-19.4), a greater number of principal rays in the lower lobe of the caudal fin (9 vs. 8), a longer (vs. shorter) upper lobe of the caudal fin, fewer unbranched pectoral-fin rays (vii vs. viii), a higher number of predorsal scales (14-15 vs. 12-13), a lower number of transverse scales below the lateral line (2 vs. 21/2), a narrower caudal peduncle (44.0-52.9 % caudal-peduncle length vs. 57.9-76.2) and a dome-shaped (vs. slightly pointed) rostral cap. The lectotype of P. rowleyi was also designated. © 2013 The Ichthyological Society of Japan.
