    Thanks Charles – I haven’t seen it but can’t view from work so will watch tonight.

    So my friend says S. nantaiensis is always misidentified as S. puliensis when traded between Taiwan and Japan but that doesn’t really help in terms of the fish reaching Europe and the United States.

    More digging to do.

    Hi.
    I didn’t understand a Taiwanese language, but I searched for a transcribed site in a Taiwanese language.

    It seems to be explaining the difference between S.puliensis and S.nantaiensis by this site.

    There were other such sites.

    like this?




    my females are all larger and play the dominant part.
    tell me if you need detail pics.
    I would still say: s. puliensis
    cheers Charles

    So I sent some of the photos posted by Charles and Odyssey to Dr. Te-Yu Liao who has confirmed the fish to be S. puliensis and therefore traded illegally (his words).

    Still strikes me as weird but I’m not arguing with the experts so will go ahead and finish the profiles.

    did you ask Farid for more pics?
    at least I hope it’s s tonkinensis. according to Liu/Cheng/Yang from 2009 it could be. going through the stocked pics I’m still not shure

    No didn’t ask him Charles – he always seems very busy. What makes you doubt the id?

    different looking fish going as s. tonkinensis, Matt http://www.google.ch/imgres?q=sinogastromy…965&bih=696

    it looks like a hemimyzon for me, may be h papilio. looking at the bodyshape – small “waist”, long body, long caudale and headform – it can’t be a sinogastromyzon?

    http://www.eol.org/pages/24439?expertise=middle

    may be it’s better to see that way
    s. sp “tonkinensis”


    s. wui

    the radiographs of sinogastromyzon/hemimyzon show clear differences. could link them as soon I find the source where I’ve got them

    (edit) I just went through some pics: the relation width/length is smaller in sinogastromyzon (about 1:4,5), than in hemimyzon (about 1:5.8) taken at the basis of the dorsal fin/SL and in total.
    on the other hand: in Amazonas mai/june 2010 there is a picture of sinogastromyzon szechuanensis by Z.Hang which shows a similar headshape. may be he’s the one to ask?
