Type locality. Puerto Rico: 18°24’30”N, 65°38’30”W, 9 fm ( 16 m ) ( Bartsch 1933 , Sta. 69; Fraser 1937b ). Current status. Valid. Remarks. Fraser (1937b) described Aglaophenia meganema based on material collected during the Johnson- Smithsonian Deep-Sea Expedition to Puerto Rico and vicinity. No gonosome was observed. The holotype designated by Fraser is currently recorded as a syntype at the NMNH (USNM 43290), although the specimen count is given as one. We found a single colony with several plumes in the collection, constituting the holotype . Material of the species at the RBCM (BCPM 976-00790-001), labelled “co-type”, is a paratype . Bogle (1975) regarded A. meganema as a probable synonym of Macrorhynchia grandis ( Clarke, 1879 ) . It is currently listed as valid in WoRMS, and we adopt that conclusion. While no corbulae were present on the holotype , its morphology corresponds well with diagnoses of the genus Aglaophenia Lamouroux, 1812 .
