A new record of the meiobenthic priapulid Tubiluchus from Cabo Verde and a comparison of external characters in adults within the genus
Two specimens of the genus Tubiluchus (Priapulida) are reported from Cabo Verde, this is the southernmost record in the Eastern Atlantic for this genus. Specimens likely belong to T. lemburgi, a species known from the Canary Islands. There are some minor differences between Cabo Verde and Canary Island populations. For better comparison, the species T. lemburgi and T. corallicola are reinvestigated and characters insufficiently documented in the literature are described. Some taxonomically important characters are clarified, because they have been described using various terms in the literature. A comparison of characters between all described Tubiluchus species identifies several differences, especially in the structure of scalids, buccal papillae and pharyngeal teeth.
