A new Pachytriton of the P.changi group is described from Guangdong, southern China:

Chen Li, Zhiyong Yuan, Haibin Li, and Yunke Wu, 2018. The tenth member of stout newt (Amphibia: Salamandridae: Pachytriton): Description of a new species from Guangdong, southern China. Zootaxa 4399(2):207-219.

Abstract

Field surveys of less-explored forests often lead to discoveries of new amphibian species. During a series of field surveys in early 2017 at Mt. Lianhua (the Lotus Mountain) of Lianhuashan-Baipenzhu Provincial Nature Reserve in southern China, we found an undocumented population of stout newt, genus Pachytriton. Based on its distinct morphological characters and large genetic divergence from congeners (uncorrected p-distance > 5% in either mitochondrial nd2 or cytb sequences), we describe this population as the tenth species of the genus: Pachytriton airobranchiatus sp. nov. It can be distinguished from other members of Pachytriton by a combination of the following morphological characters: prominently elevated distal end of the epibranchial bone showing as two conspicuous protruding bulges behind the head; dorsal coloration can be either spotted or unspotted; bright orange dots absent on dorsum; costal grooves absent between axilla and groin; fingers I and toe I slender, do not forms a volar pad; dorsal tips of fingers and toes brown; and tips of fore- and hind limbs could contact when limbs adpressed against body flank. Phylogenetic analysis grouped the new species with P. wuguanfui, P. xanthospilos, and P. changi. Currently, the new species is known from the type locality and an adjacent mountain peak at about 1000 m elevation. It inhabits small montane streams in broadleaf forests near the top of the mountain.

    Hey y'all, recently my juvenile axolotl's tail has been floating and can swim down but his tail lifts to an angle and I believe that it is stressing him out. He gets in between his plants to balance himself and I am cleaning out the bottom of the tank with my baster. I believe I overfed him and he also may have eaten many air bubbles. He's been like this for nearly 1 1/2 days.

    Hey, does anyone know if hot glue is fine to glue rocks together?

  • MVM1991:
    Should be. Hot glue is good when dry I believe, just don't let it get too hot and you should be good. Most super glues are good as well just watch out for flume warnings

    hello, I am currently tubbing my axolotl due to cycling the tank. I have read different answers on how many times to do a 100% water change a day when tubbing. Some say once and some say twice. I just want to actually ask and get answers for myself. Thank

    As often as you need to keep the water clean! Since you´re cycling, I assume you have a test kit. Just test a few times to see how long it takes for your ammonia to go up, and as soon as it does, change the water.

  • Kwags:
    Yes,I have the master test kit. Thank you! So just test the water in the tub that my axolotl is in now to gauge off of for changing?

  • Murk:
    That´s the most accurate. Depends on the size of the tub etc. - you just want to make sure the water is always clean

    When little axolotls are tubbed is it common for them to get a little more spunky then usual? Water temps around 64-65 F and has been changed today with prime added

    Uh. That depends on your definition of "spunky"?

    Hi does anyone know if jungle fungus clear is safe to use for my axolotl? She has some either fungus or bacterial growth on her fillibrae and maybe body and I read that's good to use if you aren't sure if the problem is bacterial or fungal

    That jungle fungus clear. I've been dealing with some fungus with my axolotl on and off this summer. The Holtsfreter solution and water changes just seem to do the trick after a bit

    Where do you get the holtsfreter solution? I've been upping water changes but salt bath seems to be more stressful/harmful than beneficial because she does not like to be caught!
