ABSTRACT

The heteronemertean Baseodiscus quinquelineatus (Quoy and Gaimard, 1833) is identifiable by five black-or-brown longitudinal dorsal stripes and two same-colored ventral ones on a greyish or milky white body. This ribbon worm has a wide distribution in the Indo-West Pacific region. In the Philippines, the species was first reported from Gaspar Island, Marinduque in Luzon in the 19th century. In this article, we report the occurrence of this heteronemertean – identified by its external morphology – from the island of Mindanao in Carmen, Agusan del Norte. This is the first published record of B. quinquelineatus from Mindanao, making it the first ribbon worm species reported from this island.
