Fowler was given the local name Yahnarache (yanarache ?). At least in some 
localities it is known as rumiuma, or ‘‘red-tail.’”’ This name is also applied to one 
or more quite different fishes. 
The generic appellation Semitipicis has been justified on the very numerous, 
small scales, 85-110 in the lateral line; median predorsal scales growing deciduous 
with age, thin, crenate; postdorsal and preventral areas rounded, the latter trench- 
ant, but without carina; head wider and flatter than in latior, upper profile more 
elevated and convex; origin of dorsal fin nearer snout than to tip of the adipose fin; 
dorsal fin truncate, or with some of the anterior rays produced as long as the head.
