Tylototriton wenxianensis (Wenxian Knobby Newt)

Well, I don't want to hold you in suspense any longer than I have to, so here's what it seems to say based on my understanding of Japanese, which shares the same written language to a large extent.

With T.wenxianensis, the protrusions on the side of the body are developed to a greater extent, and there is no clear border showing where the
dorsum ends and the venter begins. The wrinkles on the belly are more irregular. It also seems to say something about the color of the cloaca area being the same as that as the (underside?) of the head.

Now, with T.asperrimus, the protrusions are more
roundish and there is a clearer separation between each of them. The skin of both the dorsum and the venter is smoother and shinier. There are many thin wrinkles on the venter, and the coloration on the area of the cloaca (?) is lighter.

I guess what we have to do now is to compare the pics to see which conforms with which description -- after getting a more decent translation

The source of the above information (well, the Chinese at least!) is Rare and Economic Amphibians of China.
 
Ah, I just checked the Chinese with my Hong Kong colleague, so you should all forget that lousy translation I posted yesterday. In fact, I will soon delete it.

What it now seems to say is:

With T.wenxianensis, the skin of the sides of its body has protrusions that are almost the same size, and there is no clear separation between them. There are no horizontal wrinkles on the belly. The coloration of the cloacal area is the same as the rest of the body and head.

Now, with T.asperrimus, the protrusions are more roundish and there is a clear separation between them. The skin of the venter is smoother than that of the dorsum. There are many horizontal lines on the venter, The coloration of the cloacal area is a light green.
 
This is from the English abstract of Deng & Yu 184. A new subspecies of salamander from Sichuan. Acta Herpetologica Sinica 3: 75.

This new subspecies differs from the nominate subspecies in:
1. warts on the flank irregular, with no distinct demarcation line between each other;
2. distance between the nostrils shorter than from the snout to eye;
3. periphery of the anus dark-brown;
4. ventral surface rough with numerous warts

pingwuensis is a synonim of wenxianensis, however this description is very different from yours, Tim.
 
Hi Wouter

Thanks for that info. Hmmm...some aspects of that info are indeed different, but there seem to be similarities as well. They both suggest some coloration in the anus area in the case of asperrimus, and that the the warts are not as clearly demarcated in the case of wenxianensis and the skin on the skin on the venter is rougher in the case of wenxianensis than in the case of asperrimus.

Please let me know if you ever come across the entire document
