Gong, L.; Lim, S.-C.; Yang, M.; Li, X. (2021). A new species of Macandrewia (Demospongiae, Tetractinellida, Macandrewiidae) from a seamount in the Western Pacific Ocean. Journal of Oceanology and Limnology. 39(5): 1730-1739.
A new species of Macandrewia Gray from a seamount near Yap Trench in the Western Pacific Ocean was described. Macandrewia yapensis sp. nov. is distinct from its congeners by possessing a foliate shape with contorted lamellae, tuberculiform terminations of desmas, and unique size of spicules. This is the third species of Macandrewia described from the Pacific Ocean. In addition, a partial sequence of COI gene was obtained from the new specimen and then it submitted to GenBank. Phylogenetic tree constructed with the partial COI sequences appears to exhibit a more congruent relationship with morphological data of macandrewiid species compared to 28S gene tree.
