Zhiyong YUAN, Haipeng ZHAO, Ke JIANG, Mian HOU, Lizhong HE, Robert W. MURPHY, and Jing CHE, 2014. Phylogenetic Relationships of the Genus Paramesotriton (Caudata: Salamandridae) with the Description of a New Species from Qixiling Nature Reserve, Jiangxi, Southeastern China and a Key to the species. Asian Herpetological Research 2014, 5(2): 67–79.


Abstract The matrilineal genealogy of the genus Paramesotriton is hypothesized based on DNA sequences from mitochondrial NADH subunit two (ND2) and its flanking tRNAs (tRNATrp and a partial tRNAAla). The genealogy identifies a highly divergent, unnamed lineage from Qixiling Nature Reserve, Jiangxi, China and places it as the sister taxon of P. chinensis. The newly discovered population differs from other congeners by several features of external morphology including having large clusters of dark brown conical warts on the dorsum of the head, lateral surface of the body and dorsolateral ridges. Its intermittent dorsal vertebral ridge is the same color as other parts of the dorsum and tail narrows gradually from the base to the tip. Further, the new population differs from all congeners by an uncorrected P-distance of more than 9.38% in ND2. Consequently, we describe the new species of Asian warty newt (Salamandridae) as Paramesotriton qixilingensis sp. Nov.


A key to all known species of Paramesotriton is included!


The habitat is described and shown in photos, and the new species is fully described and illustrated with color photos. One error is repeated numerously in this paper: Paramesotriton labiatus (Unterstein 1930) is incorrectly refered to as Paramesotriton labitatus Wu, Rovito, Papenfuss, & Hanken 2009. The latter is the description of P.ermizhaoi, which was recently discovered to be the same species as the earlier description of Pachytriton labiatus by Unterstein. This is both an error in spelling and in original authorship. The name appears correctly in the key.

The paper is available for free download (volume 5, issue 2):

    Hi Nerdybirds - open a thread, that usually gets more views and also allows you to post pictures and give more background information: water parameters, age, etc.

    Yeah his gills is kinda small and it can be caused by nitrate level, I am taking care of it atm, I am worried about his weight, is he only overfed or are there any kinds of problems there ?

  • MVM1991:
    Well, again, I'm no expert. But I did just read axolotls are supposed to have a body about as wide as their head. The gills I'd say are the biggest problem, which could reduce oxygen intake, which could make a whole mess of problems.

    Hello, I am a new owner of a 3 month old axolotl, and although I have done a lot of research on axolotls, I can barely find any for babies. If anyone can help me with these questions, I would be super happy. How many hours do baby axolotls tend to sleep per day? How many times should I feed it and what would be considered too much (it's current diet is freeze-dried brine shrimp and blood worms, and I currently feed it around 3 bloodworms since they are not that big)? How many times a week should I change the water and how? I have a good filter and use Prime as my conditioner to remove the chlorine and other chemicals, but I still need to figure out how to deal with ammonia and such in the water. How do I clean it's waste (should I use a dropper to easily pick it up)? I need a better cooling system because currently I use ice packs on the side of the tank and I make sure to angle my ac so that it hits the tank.

    I also leave the lid open during the day so that evaporation can cool down my tank. I want to buy a fan, but since winter is coming I won't have to buy one yet. Lastly, what water testers are effective and affordable for a broke student like myself? Please, if anyone has any advice I will love to hear it. I care for this creature too much at this point, but I have no one to help me with caring for it other than the internet :,)

    Hi LauraLobster I am a new owner of axolotls myself and have been getting advice from things like this, I feed mine twice a day on blackworms and brine shrimp blood worms are more of a treat food, a question on where you are keeping you axolotl are you keeping it in the main tank or in a tub also if in the tank did you cycle it first? and if not i suggest tubing it until the tank it cycled, mine are still tubed since I was given bad advice by the shop people about cycling my tank and am still in the process of cycling it. I use pipettes to clean up the mess of my axolotls. I use the API mater test kit for freshwater tanks I am also a student and had to look around to find it the cheapest I could.

    Hi LauraLobster, like you I got my first ever Axolotl back in July. Iv found that he has enjoyed and eaten red wigglers well. They are a good source of protein and help provide the nutrients a young lotl needs to grow up big and strong. You will probably need to break it up into smaller pieces until they get bigger but they are what I have primarily fed my buddy since I got him. He’s actually so picky that he won’t even eat his pellets anymore and will hold out till he gets his favorite wormy.
