All the specimens representing this species are smaller than the 

 type and were collected by Mr. Smith. Changes with age are 

 noticeable in color, small or young specimens showing an obscure 

 humeral blotch and usually no black on caudal. A narrow line of 

 dusky dots* extends along parallel with the anal base on lower side 

 of trunk. The species is related to Hyphessobrycon heUotti (Stein- 

 dachner),^ though differs in the absence of maxillary teeth and the 

 dark humeral blotch not surrounded by a bright ring.
