Erromyzon Spp Id

[torso]

some weeks ago I found three unknown loaches in a shipment of about 1000 b kweichowensis, very week. a reason more to bring them home. one didn’t survive the long journey, second – protomyzon sp 01 – died after one day.
third – protomyzon sp 02 – is well up and a master of the play “look here and away I am”.
some pictures of the probably undescribed species.
protomyzon sp 01 remembered me of erromyzon sinensis but G. Ott finally tended to undescribed protomyzon.

No idea Charles but I love it! Hope they fatten up for you.

Hey Charles been on a collection trip the last few days but will check these out tomorrow and reply to your mail.

Sp. ’02’ looks like an Erromyzon to me Charles. *strokes chin* Waiting for a paper before guessing at sp. ’01’.

[Matt]

I think both fishes are Erromyzon spp. because according to Kottelat Protomyzon is endemic to Borneo. First one could be E. compactus (less body bars than E. sinensis) but likely to be undescribed as E. compactus was described from Vietnam. Second one looks like E. yangi (no bars on body) which is from the Pearl River where I believe B. kweichowensis is collected for the trade.

Hi Charles Dave Neely, who co-described E. yangi, says the plain fish:

“looks suspiciously like E. yangi based on the mouth shape/size of median lobe, and relative size of eye, although it would be nice being able to check LL counts. The evenly pigmented dorsum fits, too, but I would have expected a more pronounced lateral stripe. If it is possible to monitor life coloration and take additional photos as this individual fish ages, that would be very interesting.”

Is it still alive?

[torso]

yes Matt. thanks for the news.
it does very well. I added about 20 gastromyzon and others to the quar.tank and that was a godd thing to do. it’s not so shy any more so I could take some pictures.

a more pronounced lateral stripe.
can be seen more clearly. would take some time do take pics.
et voilà
at the size of 3.5 cm

Was just going through my pic library looking for E. sinensis ones and came across this of Mark’s. Looks like your first fish above Charles?

thanks Matt
looks alike but: stripes are “regular” and without lateral thickening. and I can’t guess a black spot at the margin of the tail-fin.
do we have another choice?

[torso]

it’s now in the tank with “rarities” and does well.
here a picture with 4 cm

Charles do you know (or can you find out?) anything about the origin of this fish? I sent Dr. Neely your last image and he reckons it might be an undescribed one now.

[torso]

I’m sorry, but even the importer didn’t know about their existence until I detected them in a tank with at least 500 b. kweichowensis (made one part of a b kweichowenis shipment). there were two species, one specimen as shown in the first pics, two erromyzon cf yangi. only one specimen survived as they were already very “shiny”. it’s a luck this one survived and is doing well.
somebody is now having a closer look on ervery shipment; once with unknown hillies from thailand, but they died before I got them. as I’m not there every week it’s difficult to get the “not fitting” specimen home to me. and sometimes I have not time enough to have a closer look. this way I missed some sewellia albisurea which are very close to s sp “spotted”; not really visible in a not illuminated tank, just a little irritation about the lateral pattern. and the enlightment came too late. bad luck
would be great to know more
