The Chinese giant salamander (CGS), Andrias davidianus (Amphibian, Caudata, Cryptobranchidae), is endemic to China. After overhunting in the 1990’s, it is very difficult to find the CGS in the wild. Due to mating disorder, the captive breeding population is genetically confounded. The genetic backgrounds of all wild-release individuals in China are not explicit. Herein, we reported four living wild-type complete mitochondrial genomes of this species. The gene order and contents are identical to those found in typical vertebrates. Thirteen protein-coding genes (PCGs) of 7 A . davidianus (4 from this study, 3 retrieved from GenBank) and 11 other closely species retrieved from GenBank were used to reconstruct phylogenetic tree. The Maximum likelihood (ML) topology shown that the clade of CGS has two subclades with a high support (100%). This study provides partial fundamental information for further exploring the true genetic background of whole population of A . davidianus .

Genetically-defined biodiversity units must align with practical conservation frameworks, and most conservation is conducted at the species level. Chinese giant salamanders have traditionally been interpreted as the single widespread species Andrias davidianus, but molecular studies have reinterpreted this taxon as representing multiple allopatric clades, and competing taxonomic hypotheses support different numbers of candidate species. We conducted species delimitation analyses using tree-based models (General Mixed Yule Coalescent, Poisson Tree Processes) and alignment-based models (Bayesian Phylogenetics and Phylogeography) to interpret diversification across Andrias within a comparative systematic framework, using 30 mitogenomes representing all recognised Chinese clades. Nearly all tested models provide support for at least seven statistically-resolved Chinese species-level lineages, and most provide support for nine species. Only four species have available names. Chinese Andrias populations are Critically Endangered, but unnamed species cannot be incorporated into national or international conservation frameworks and risk being excluded from recovery efforts. We urge taxonomists and conservation practitioners to focus more attention on the world’s largest amphibians, and non-standard taxonomic approaches may be required to name these species before they disappear.

“A New Species”

Taking as its starting point Michel Foucault's use of the biological species metaphor in his claim that, in nineteenth-century Europe, “the homosexual was now a new species,” this article considers the sudden explosion of homoerotic activities and cultural representations in Greater China beginning in the late 1980s and early 1990s. The article focuses in particular on four literary works dating from around 1994 that examine queer individuals in relation modern institutional structures associated with disciplines of biology/science, reportage/media, medicine/activism, and policing/psychiatry. At the same time, however, through attention to the role played by these institutional structures in shaping new queer subjectivities, each of these four works emphasizes the subject's ability to intervene in the discursive formations within which those same subjectivities are positioned and thereby to narrativize the subject's own identity.
