The Congo lyretail, Aphyosemion congicum, is a killifish from western Democratic Republic of Congo. It may be restricted to the area between the Kwango and Gamba rivers, but the type series came from a commercial shipment and its natural range remains unconfirmed. The Kwango drains to the Congo through the Kasai.

Etymology

Edit

Aphyosemion: from the Greek aphúe (Gr. ἀφύη), meaning 'a small fish', and semeion (Gr. σημεῖον), meaning 'banner, flag', in reference to the "ornamented, often lyre-shaped" caudal fin in male individuals of genus members.#

congicum: named for the Congo River in combination with the Latin suffix -icum, meaning 'belonging to'.

Distribution

Edit

The type series was derived from a commercial shipment and this species' natural range remains unconfirmed. It may be restricted to the area between the Kwango and Gamba rivers, the latter a tributary of the former, in western Democratic Republic of Congo. The Kwango is itself a tributary of the Kasai, an affluent of the Congo.
