    Hi all

    a first species of the genus Physoschistura has been imported from Northern India, Saillong region(?).

    I’ve got some specimen of this small loach. They are not very showing, but interesting

    Here some pics of the freshly arrived specimen. They don’t show the brown coloured bands of the specimen photographed by F. Schäfer for Glaser. Could depend on the lightning. May be they are going to change when settled.

    Size is from 3.5 to 5 cm. Interesting the number of bands: 7-9, depending on the age(?). On the other hand some seem to be splitted, which could be due to the stress.

    The first two rays of the dorsal fin are branched. Three pairs of barbels. No more details so far.

    A better judgement about the species depends on the informations in the description of P. elongata.

    Hi Charles is the first dorsal ray branched?

    sorry: the first two are joining half way, Matt. That’s what seems special to me.

    cheers Charles

    The caudal-fin doesn’t seem forked enough for it to be P. elongata Charles. Is the lateral line visible at all?

    Edit: ‘Saillong’ might be a misspelling of ‘Shillong’ in Meghalaya?

    DSC_2283-02.jpga better pic of the dorsal fin. Seems that a first shorter ray is joining the second. The lateral line seems to be complete. The longer specimen have darker bands now. Seems not to be P. elongata.

    Cheers Charles

    Hi Charles, Physoschistura spp. tend to have a strongly-forked caudal fin which this doesn’t. Is there any way you can get a photo of the mouth from underneath?
