| Abstract |
Two new Oxynaspis species associated with antipatharian corals are described from the AURORA expedition in the Philippines and from Taiwan waters. Oxynaspis auroraensis n. sp. was collected from the Philippines at more than 500 m depth and belongs to the fully armored group of Oxynaspis. The umbo of the carina of O. auroraensis n. sp. is located in a proximal position with the carinal distal arm about 3.5 times longer than the basal arm. Such a position is diagnostic, distinguishing this species from all previously described Oxynaspis species. Oxynaspis biradius n. sp. was collected from Taiwanese waters at 20-30 m depth and belongs to the reduced scutum group of Oxynaspis. The morphology of O. biradius n. sp. is close to that of O. joankovenae Van Syoc & Delkelboum, 2011, but differs in having two distinct white rays on the scutum and a more pointed tergal spur. From molecular analysis in the sequence divergence of the 12S and COI region, O. auroraensis n. sp. and O. biradius n. sp. form distinct monophyletic clades and the interspecific divergence suggests that these two species are distinct. |
