Description of a new species of the genus Aselliscus (Chiroptera, Hipposideridae) from Vietnam

Vuong, Tan Tu Csorba, Gabor Goerfoel, Tamas Trident bats found in mainland Southeast Asia are currently subsumed into a single species, Aselliscus stoliczkanus. In this study, we examined morphological and genetic data from different populations from Southeast Asia, with a special focus on specimens from Vietnam. Our analyses support the existence of a further species of Aselliscus in northeastern Vietnam that separated from A. stoliczkanus sensu lato (s.l.) during the late Miocene. Within the latter taxon, we identified five geographic lineages that diverged from each other during the Plio-Pleistocene epoch. Some of them may also correspond to further separate taxa, but additional molecular and morphological data are needed to test this hypothesis. Herewith, based on the combined evidences we describe the northeastern Vietnamese population as a separate species.

Morpho- structure characteristics of some karst caves in Yen Mo- Tam Diep area, Ninh Binh province

Doan, Dinh Lam Ninh Binh province is well known as an area with famous karst landscape that likes inland HaLong Bay. An attractive and charming cave system is developed in Triasic limestones of the Dong Gi ao formation, created a wonderful sites for tourism. The exciting features of karst landfor ms in the Ninh Binh province are mogots. It is mogots make Ninh Binh province became inland HaLong Bay. In the study area most wide spread karst forms are: mogots, karst slope and peaks, karst remnant relief, karst relict relief, karst polje, karst dry valley and karst ponor and sinkholes. Because of tropical climate, limestones in the study area undergone a strong chemical weathering process, created many wonder ful and diverse landscapes on the surface and cave system underground. Many caves of different size and forms were devel oped underground of limest one mo...
