This is the type species of the genus, fairly ubiquitous in the aquarium trade, and represents an excellent choice for the newcomer to fishkeeping since it's less demanding than most congeners. It's sometimes referred to as 'Beckford's pencil fish' or 'brown pencilfish'.

Type locality is given by Fowler as 'Rio Madeira about 200 miles east of W. Long. 62°20', Brazil'.
