The names are accepted as available because no one has bothered to investigate thoroughly if they are Code-compliant. This is exactly the same situation as for Glyptothorax chavomensis until we confirmed that the name is not available.

There is a possibility that none of the names published in this journal since 2011 are available, since the names are not registered in ZooBank and the journal seems to be electronic only.

Kamphol has a live photo of the new species:

Description should be out soon.

The fish (if correctly identified) is collected from a new locality within its known distribution, so it does not constitute a range extension. The authors also do not understand what a topotype is. A topotype would need to be collected from the type locality, but their collection locality is on the...

naturalart wrote: ↑02 Sep 2023, 15:04 Hi Silurus, did you take/remember the temps?

No, because water temp has never been an important parameter in my field work. But I’d estimate it to be about 23–25 degrees Celsius.

I may be one of the few members here who have caught them in the wild. The water was tea-colored, acidic (pH was not more than 6.0, maybe around 5.5 if I remember my notes correctly). Fish were caught amongst dense banks of Eleocharis -type plants growing along the shoreline of a large, slow-flowing...
