Which Leiocassis is this one from Kapuas?





Micropogon? Barbels and occipital crest/predorsal plate fitted at least as well for L. myersi when i checked Roberts book..

What a fat hybrid of tank, train and vacuum cleaner during feeding time! Started fearing for the lives of my Pangios and removed him.

I am certain that this is not Pseudomystus myersi, as this species has confluent adipose and caudal fins.
Probably P. breviceps or something similar. Might even be a member of the P. stenomus group.

I found P. breviceps in Kottelat's book: "known from two specimens caught 75 years ago". The picture of the corpse pretty much matches that.. Is there a more fresh photo of P. breviceps available and/or literature discussing these species/species groups?

Antti

I am not fully convinced that the fish is P. breviceps (largely by dint of geography). It's probably something closer to P. stenomus, but the whole group is in a fine mess now.
