Will be making a start on this genus soon as nearly done with Gastromyzon for now. I've only ever kept H. confuzona though so will need help as usual. /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" /> I know Mark also has H. confuzona but is anyone else here keeping any species?

Haha I was hoping you two would say something like that! Charles I'm always ready for new pictures. /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> Gastro ones should be up within the hour.

Here are the images of live specimens from Tan, H. H. and P. K. L. Ng. 2005
Homaloptera parclitella, a new species of torrent loach from the Malay Peninsula, with redescription of H. orthogoniata (Teleostei: Balitoridae). Ichthyol. Explor. Freshwat. 16(1): 1-12.

These clearly show the differences in patterning between the two species as given by the authors.

H. orthogoniata ALWAYS has THREE dark saddle-shaped markings on the body plus one on the caudal peduncle:

H. parclitella ALWAYS has TWO dark saddle markings plus one on the caudal peduncle:

...whereas H. confuzona is more variable and has less well-defined saddles. Pics from Jim and Mark:

Nice comparison Matt. Are you going to put it like this in the knowledge base? Makes it easy to see the difference.

I wrote to Dr. Tan to ask if we could use the images (also attached a pic of Odyssey's unknown Gastromyzon for his interest) but received no reply. /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

Not sure about the Knowledge Base - I've tried not to clutter profiles up with images of other species wherever possible. What I could do is add something in the article section and link it to the relevant profiles, but if you think it's better to include images of all three species in each profile I'll do that.

I'd link an article mate, less clutter as you say.

Hmm Charles I still think the first one is too young to identify 100%. /unsure.gif" style="vertical-align:middle" emoid=":unsure:" border="0" alt="unsure.gif" />

Of the others pic 2 should be H. orthogoniata (3 saddles) and the last two should be H. parclitella (2 saddles).

Charles pic 1 should be H. orthogoniata, pic 2 H. parclietella. Do you guys want the paper?

The red Homaloptera seems strange to me...
