Nannostomus marginatus, commonly known as the dwarf pencilfish, is a freshwater species of fish belonging to the genus Nannostomus in the Lebiasinidae family of characins. They were first described in 1909 by C. H. Eigenmann and are typical of members of this genus being small, elongated fish with prominent horizontal stripes.

They occur widely on the South American continent having been recorded in Brazil, Guyana, Colombia, Suriname, and Peru.

Common name and synonyms

The common name given to N. marginatus is typically dwarf pencilfish, reflecting its diminutive size, although it is not the smallest known member of the genus since N. anduzei has a maximum length of only 16 mm. The only alternative Latin name is N. marginatus picturatus, a variant described by Hoedeman in 1954, but now regarded merely as a synonym.
