Serrasalmidae

Serrasalmus caribe

 

Current status: Synonym of Pygocentrus cariba (Humboldt 1821). .

 

HISTORICAL AUTHOR REMARKS

Serrasalmus caribe Valenciennes differs in the D. 20, A. 27, and no scapular spot is mentioned or represented on the figure. It may also be noted that Serrasalrno albus Humboldt and Valenciennes is evidently an older name for S. caribe, and should therefore replace it. Serrasalmus rhombeus (Linnaeus) differs according to Miiller and Troschel's figure7 in having more palatine teeth.

Serrasalmus marginatus (Valenciennes) differs in the lower anal edge being black only, but not the hind caudal edge. Both S. spilopleura (Kner) and S. gymnogenys (Giinther) are said to have 95 scales.

S. elongatus (Kner) differs in its elongated contour, the depth 2 2/3. S. gibbus Castelnau apparently has no spots whatever on the trunk. S. brandtii (Liitken) has the scales 90, and the coloration is largely uniform or with minute blackish dots.

Among the species I have examined, S. humeralis Valenciennes, S. maculatus Kner, «S. aesopus Cope, S. iridopsis Cope and S. unimaculaius Cope, all were found to have more palatine teeth in each series, besides various other characters.

S. paraensis (Steindachner) I have not seen, and also have not been able to consult its original description. (h'oxxos, berry-red; ytvstov, cheek; with reference to the ruddy cheek).
