the picture on the species page is not IMHO.
...pectorals in the picture seem to be significantly longer.Gosline, 1947 wrote:Pectorals reaching about 1/3 of the way along ventrals...
Are there any information available from where exactly the pictured Hypostomus came from ?
This is what I consider to be the "real" H. myersi::Gosline, 1947 wrote:The ground colour of this fish is steel gray. In four specimens the head and body are covered with whitish punctulations;in the fifth specimen the fore part of the body is marked with predominantly vertical,irregular light lines. The dorsal fin has light punctulations on the outer part of the rays and interradial membranes; there tends to be an irregular light line running down the basal half of each interradial membrane. Other fins with light punctulations which only occasionally tend to form lines. The belly seems to be mottled in those areas where plates have developed.

This species is well known in the Iguazu area and always looks quite similar, often with clear whitish/yellowish fin tips and fine wormlined pattern which might have faded during conservation.
