Camera-trap evidence that the silver-backed chevrotain Tragulus versicolor remains in the wild in Vietnam.

In an age of mass extinctions, confirming the survival of lost species provides rare second chances for biodiversity conservation. The silver-backed chevrotain Tragulus versicolor, a diminutive species of ungulate known only from Vietnam, has been lost to science for almost three decades. Here, we provide evidence that the silver-backed chevrotain still exists and the first photographs of the species in the wild, and urge immediate conservation actions to ensure its survival.

Description of Coeliccia bhriulieci sp. nov. (Odonata: Zygoptera: Platycnemididae) from central Vietnam.

Coeliccia bhriulieci sp. nov. (holotype male from Tay Giang district, Quang Nam province, central Vietnam, deposited in the Zoological collection of the Southern Institute of Ecology, Vietnam Academy of Science and Technology, Ho Chi Minh City, Vietnam) is described based on male specimens. The new species is easily distinguished from other Coeliccia species in the Southeast Asian region by the combination of its blue abdominal tip, black anal appendages and structure of genital ligula with two long flagella extending from lateral corners of apical segment.
