Alas, the "M. cavasius" of Myanmar is now known as Mystus falcarius (below).
Kudos HH!

And not to take away from your original post of the new Glyptothorax.

Glyptothorax panda, a dwarf (~ 3 cm) species.

They're all from Chantaburi, HH. I was trying to depict the variation of patterning, and to that effect may have inadvertantly implied some sort of norm for the locality.

Anyways, longterm captive SE TH G. fuscus will revert to the typical tri-saddle/marking common to lampris . Only superficial ...

The Indochina Glyptothorax picture is getting a lot clearer, thanks HH. Could've sworn it was a mess just half a yr ago.

All peninsular Thai-Malay "G. major" turning out to be G. fuscus then? (They're more light-grey and blotchy than the red-browns of SE TH (ie.Chantaburi).)

Looks like an albino L047.

Point taken. Are these structures also found in related but more sedentary bagarius and glyptothorax?

I might offer the opinion that they may be chemo-receptors for the schreckstoff (alarm or fright substance) mechanism typically found in schooling fish. Gagata are strongly schooling fish unlike the other well known electroreceptive fishes found in nature (Malapterurus, Electrophorus, gymnotids, etc ...

Keep on truckin' HH!!

In fact enough of a fishery that albino specimens have shown up from time to time. Here, different types of albinism in two egg-laden (green eggs ...

Jools, funny you should mention Kottelat's Fishes of Laos book. Coincindently, he uses a picture of Mystus rhegma (figure #336) to illustrate Mystus multiradiatus (errata).

The new Cat-eLog entry (19 July 05) for Mystus albolineatus should be the rare Mystus rhegma. Beautiful catfish and a personal favourite.

Mystus albolineatus:

Just to add to the id confusion. These elongate Hara cf. filamentosa are from the Sittaung Rv. Top one is of normal coloration, bottom one is a red phase.

Try this for limited info.

Yes, M. pulcher. M. rufescens will have longer adipose, otherwise they're relative lookalikes from Myanmar.
