A large, smooth-skinned warty newt with a semblance of horns at the back of the head, was previously reported as unknown and closely related to Paramesotriton (Allomesotriton) longliensis.
In an open-access paper published October 9, 2012, this species is formally described as Paramesotriton (Allomesotriton) maolanensis. The paper includes anatomical, genetic, and ecological data. There is no evidence of genetic sharing with P.longliensis, which further supports the view that P.longliensis and P.zhijinensis (which is more distant genetically) are separate and distinct species. The new species is thus far only known from a deep, stream-fed pool in a nature reserve, which has no above-ground outlet. The pool presumably flows into an underground river, and the new species may thus be partially troglobitic and may also be located elsewhere in the stream system.
Additional data are presented which suggest that P.(A.) caudopunctatus consists of at least two distinct species.

Abstract
In this study, we describe a new species of salamander, Paramesotriton maolanensis sp. n., from the Maolan National Nature Reserve, Libo County, Guizhou Province, China. The new species is placed in the genus Paramesotriton based on morphological characteristics and molecular data. It differs from all other members of the genus in a number of morphological characteristics, especially in its much larger body size, absence of granular warts from head and body, largely reduced external eyes and peculiar shape of epibranchia in hyoid apparatus. We examined the relationships of nuclear POMC haplotypes between and within the new species and six recognized species. POMC variation and published mitochondrial data suggested that the new species’ closest known relatives are P. longliensis, P. zhijinensis and P. caudopunctatus, and it should be placed into the P. caudopunctatus species group or subgenus Allomesotriton.
