Original description: first described by Koumans in 1933 in Zool. Meded. (Leiden) v. 16 (no. 1-2); ref. 2673. From 2 specimens collected at Banggai, e. Sulawesi [Celebes], Indonesia, near shore.. Validated by Allen & Steene 1995.

Word origin: The genus Pterapogon is from the Greek root(s): pter meaning fin or wing; apo meaning from, off, or away; and gon meaning offspring. (Perhaps due to the mouthbrooding characteristics of this family). The genus kauderni appears to be in honor of Kaudern.

Vernacular name: Banggai cardinalfish, Banner cardinalfish, “Outhouse” cardinalfish (Allen, 1995)
