Diagnosis Maxwell et al (2022: 12 of 16) "Gorgoniapolynoe pseudocaeciliae sp. nov. was previously illustrated by Pettibone (1991) as a morphotype of Gorgoniapolynoe caeciliae (USNM 133356). This current study reexamined USNM 133356 and the morphological features concur with the Gorgoniapolynoe pseudocaeciliae sp. nov collected for this study. The distinguishing characters that separate this new species from of G. cf. caeciliae are: (1) the presence of only one type of robust notochaetae, which is curved and smooth; (2) a distinct digit-like postsetal lobe on the anterior neuropodium, which projects ventrally to an extent that it can clearly be seen when viewing the neuropodium from the anterior; and (3) a small, crescent-shaped chitinous area on the modified first elytra pair, that takes up approximately a quarter of the total area of the elytra, as opposed to the one in G. cf. caeciliae, which is significantly larger. Molecular analyses also support G. pseudocaeciliae sp. nov as a distinct species from G. cf. caeciliae. [details]
Etymology authors: " ... named G. pseudocaeciliae due to its morphological resemblance to G. caeciliae." [details]
Type designation Maxwell et al (2022) do not have normal type designation and type locality statements. Instead they include two sentences. The first that: "Suggested holotype: USNM 133356, east Atlantic" The second that: "USNM 133356 should be redesignated as the holotype of G. pseudocaeciliae" . USNAM 133356 is a specimen that comes from Hartmann-Schröder (1885), collected at 40.55°N, -9.4333 W off Portugal at 1170 m, and which Pettibone (1991) figured and included in Gorgoniapolynoe caeciliae [details]
Type locality offshore Portugal, RV Thalassa, station Y405, 40.55 N, -9.4333 W, (40 33' N, 9 26'W), , 1170 m, 1st Sept 1972, on Corallium niobe identified by M. Grasshoff. [details]
