Ctenolucius beani

Ctenolucius beani has a maximum standard length28.6 cm (11.3 in). There are between 9 and 11 soft rays supporting the dorsal fin, and 10 to 13 supporting the anal fin. This species differs from its congener, C. hujeta, in having dark, wavy stripes on the body in all individuals with a standard length greater than roughly 80 mm (3.1 in), while in C. hujeta these are typically absent.

Ctenolucius beani is found in northern Colombia and Panama. Its range extends along the Pacific slope of Panama, from the Santa Maria River drainage east to the Colmbian border, and then south on both the Atlantic and Pacific slopes of Colombia in the Atrato and San Juan River drainage systems to the Mira River drainage system. It is found in rivers, lakes, streams and marshlands, as well as canals, where the bed is made up of sand and decomposing plant material.

Ctenolucius beani is one of two species in the genus Ctenolucius. This name combines cteno, from the Greek ktenós, meaning "comb", and the Latin lucius, which means "pike". The specific name, beani, honours the American ichthyologist Barton Appler Bean, who was assistant curator of fishes at the United States National Museum and the brother of the ichthyologist Tarleton Hoffman Bean.
