tailieunhanh - On taxonomic status of pseudoberylmys muongbangensis, a new species and genus described from Son La province, Vietnam; does it new or pseudo new species
In paper, unfortunately, authors also did not perform any genetic analysis of specimens obtained, which can be used to appreciate the status of new taxon based on molecular data. The fact forced us to organize an independent expedition to obtain original materials from type locality to perform comparative morphological and molecular genetics analysis to validate a taxonomical status and evolutionary relationships of these animals. | HỘI NGHỊ KHOA HỌC TOÀN QUỐC VỀ SINH THÁI VÀ TÀI NGUYÊN SINH VẬT LẦN THỨ 4 ON TAXONOMIC STATUS OF PSEUDOBERYLMYS MUONGBANGENSIS, A NEW SPECIES AND GENUS DESCRIBED FROM SON LA PROVINCE, VIETNAM; DOES IT NEW OR PSEUDO-NEW SPECIES? ALEXANDER E. BALAKIREV, BUI XUAN PHUONG, PHAM MAI PHUONG Russian-Vietnamese Tropical Research and Test Center VYACHESLAV V. ROZHNOV Severtsov’s Institute of Ecology and Evolution of RAS Wide scope of investigations in ecology and biodiversity has been held during last century in Indochina and Sunda region, but in terms of fauna of mammals, Southeast Asia is still remains one of underinvestigated region in the World. It can be illustrated by the facts that new species have repeatedly being described from Laos, Northern Vietnam and Thailand during last decade [Averianov et al., 2000; 2,3,5,6,9] and there are good reasons to believe that the aria can present to a zoological science a lot of interesting finds. In this way, new species and genus was described in 2009 [10] in Son La province, Northern Vietnam and was named Pseudoberylmys muongbangensis. In spite of detailed morphological description, an illustrative materials did not allow to perform careful comparative taxonomical analysis based on the data presented in paper, unfortunately, authors also did not perform any genetic analysis of specimens obtained, which can be used to appreciate the status of new taxon based on molecular data. The fact forced us to organize an independent expedition to obtain original materials from type locality to perform comparative morphological and molecular genetics analysis to validate a taxonomical status and evolutionary relationships of these animals. I. MATERIAL AND METHODS Field materials: Six adult and young adult rats (field numbers MB-1, MB-2, MB-8, MB-9, MB-10 and MB-11) were trapped in course of expedition being held from 1 to 10 of March 2011 in Muong Bang commune, Phu Yen district, Son La province at the mountains forest area in vicinity of .
