The Lower Mekong: an insurmountable barrier to amphibians in southern Indochina?

Geographical information system (GIS)‐based cluster analyses and comparative ecological approaches were applied to unravel the hitherto controversially discussed role of the Mekong River as a biogeographical barrier to the amphibian fauna in Indochina. Referring to the unique and independent history of the Lower Mekong, south of the Lao–Cambodian border, this approach focused on the amphibians of southern Indochina and adjacent parts of eastern Thailand. To date, 131 amphibian species have been recorded from this region. In concordance with previous studies, our GIS‐based analyses revealed that the amphibian fauna of the Cardamom Mountains, west of the Mekong, possessed no closer affinity to the herpetofauna of the Southern Annamites. In addition, a statistical comparison of ecological characters showed an occurrence of ecological differentiation among amphibians across the Lower Mekong. Our results suggest that the Lower Mekong serves as, or at least coincides with, a biogeographical barrier in southern Indochina. Here, we discuss this hypothesis, together with selected species spatial distribution patterns, their species‐specific ecological traits and the palaeogeographical background of the region. © 2015 The Linnean Society of London, Biological Journal of the Linnean Society, 2015, 114 , 905–914.

English names for a world list of mammals, exemplified by species of Indochina

1. The lack of a globally accepted list of English‐language names for mammal species leads to various problems stemming from the reduced ability to communicate unambiguously. This impacts directly on their conservation. We use the larger mammals of Indochina to exemplify the use of an explicit set of principles designed to provide each species with a unique and non‐misleading (or at least minimally so) English name. 2. For most species, a suitable name is already in use, sometimes generally so. For species for which multiple names are in use, standardization would consist of adopting the most suitable name. Only for a very few species are all extant names so unsuitable that a neologism should be coined. One species, Panthera pardus, presents potentially insoluble problems. 3. Name standardization among the world's birds has generated some controversy, but this has not led to abandonment of the process. Much can be learned by those developing a similar process for mammals, through studying the bird‐naming process. Progress can be advanced by detractors indicating whether they oppose standardization per se, the principles used or the names resulting from application of the principles. Also, proponents of standardization should always emphasize that the purpose of the process is to produce a list available for those who want to use it, not to produce a binding selection that must be used in all circumstances.

Review of the Eospilarctia yuennanica group (Lepidoptera, Erebidae, Arctiinae) from the Indo - Himalayan region, with description of two new species and one subspecies

Twonew Eospilarctia species and one new subspecies from China, Myanmar and Vietnam, respectively, are described. Superficially the new species Eospilarctia maciaisp. n., Eospilarctia naumannisp. n. and Eospilarctia yuennanica fansipanassp. n. resemble related congeners but they can be distinguished by the differences in wing pattern, genitalia and distribution provided. Eospilarctia yuennanica guangdonga Dubatolov, Kishida & Wang, 2008 is upgraded to species level. A checklist of the genus Eospilarctia and a key to the Eospilarctia yuennanica (Daniel, 1943) species-group, based on external characters and male genitalia, is presented.
