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):

    Ok, I'll go to the pet store this afternoon to get some pH up

    Okay so what I found is lower pH can bring on the symptoms ur lil guy is having. Your pH isn’t too too low, but it is lower then recommended so it’s possible having him exposed to a low pH for an extended amount of time has caused him to be really stressed out and stopped eating. Is your tank with the sand still set up and running? And if so, what is the pH in that tank? I’m thinking a filtered tank might be the best for him, but still leave him in the tub until he seems to be improving. Could you send me a picture of the sand and of your little guy? I put my girl on sand when she was still fairly small and it is normally fine if the sand is fine.

    if the tank isn’t set up, that’s okay. I would recommend today going and getting an air stone to put in the tub that hes currently in. Creating more aeration in the water can increase pH. You can also add 1 teaspoon of baking soda very slowly for 5 gallons of water to help. I don’t know much about the baking soda thing and I’m not sure how completely safe it is. This might help explain it a little better How to adjust the pH in your aquarium

    The tank is still running, I am cycling it (for 2 weeks) with guppys

    if you have the API water test kit, check all the perimeters in the tank. We can check the cycling process with the perimeters. And I’m actually not sure how to upload a pic lololol I thought it would be easier but I tried it myself and now I’m confused! It says to attack a link, I’m not sure how that works

    You’re so welcome! Keep a close eye on him and try to offer food a couple times a day. Maybe try some pellets too for a different smell, might get him interested. Keep me updated!

    @Paige1warren, turns out my pH was spot on, the test strips I had used were no good. I bought an API kit and the levels are all fine. So not the issue :( I just posted in the forum

    Hey @Josiane ! I just responded to your post. Your little guy actually looks fairly decent for his size despite not eating well. I think it is stress from the environment

    Also I forgot to add to my response on ur thread, keep trying to feed him bloodworms and see if he will start to take them. If you get a turkey vaster you can suck up dethawed bloodworms and dangle them right infront of his nose, might get his interest.

    I rotate between blood worms and brine shrimp. He's in my bedroom and will stay there for a while, I closed the light and just left a salt lamp on. I will bring him a hiding place right away! Isn't he the cutest thing! 😂

    @Josiane An axolotl of your's size should be on a diet of chopped earthworms or live blackworms (if they're under 3"). Bloodworms and brine shrimp are not a sufficient diet.

    @Josiane Based on the photo, I believe there is a chance your axolotl may have become impacted from ingesting sand. Axolotls under 5" should not be kept on substrate for this reason.

    @Josiane The nearly diminished gill stalks are also indicative of poor water quality. You need to test your tap water's parameters using a liquid test kit (not strips! Those are inaccurate). The slime coat coming off may also be due to water quality or the water conditioner.
