Paragorgia coralloides Bayer, 1993  

( Fig. 16 View FIGURE 16 )

Paragorgia coralloides Bayer 1993: 2   .

Material examined. Holotype: USNM 50891, 01° 54´00”S – 127 ° 36´00”E, 602 m, 0 3 Dec 1909, (Albatross R/V), Obi Islands, Gomumu Island, Indonesia ( Moluccas), Ceram Sea,

Diagnostic characters. Globular 8 ­radiate derived sclerites in the surface layer with some radial ornaments subdivided in non­globular lobes ( Fig. 16 View FIGURE 16 B–D).

Description. Colonies with slender branches down to 21 mm in diameter ( Bayer 1993). Autozooid polyps in clusters. Autozooid polyp tentacles contain spindles less than 0.1 mm in length, irregularly ornate ( Fig. 16 View FIGURE 16 A). Surface of the cortex, including autozooid aperture, with unusually globular and hypermorphic radiates (mostly 8 ­radiate derived) up to 0.055 mm averaging 0.0435 mm in length (± 0.003 SD, n= 10) ( Fig. 16 View FIGURE 16 B–D). Surface radiates about 1.638 times longer than wider, averaging 0.029 mm in width (± 0.002 SD, n= 10). Despite radiates have some globular and larger rays, one side of radiates remains with smaller multilobular ornaments. Medulla with ornate spindles, rather short, up to 0.15 mm in length ( Fig. 16 View FIGURE 16 E).

Morphological variation. The number of radial ornaments of the sclerites of the surface layer, a diagnostic character, can be highly variable in number but most radiates present such a character.

Distribution. Pacific Ocean: Palau Gomumu (Obi Major) ( Bayer 1993).

Species comparisons. Bayer (1993) suggested that P. coralloides   radiates are indistinguishable from those from Corallium   spp. Although there is a great resemblance, P. coralloides   do not form asymmetrical opera­glass sclerites (e.g., Bayer 1956: Fig. 7 View FIGURE 7 ), where typically lateral rays are enlarged. P. coralloides   usually have the proximal and distal rays enlarged. Nonetheless, the tentacle sclerites somewhat resemble those from Corallium   spp., which brings up a possible phylogenetic connection between Corallium   and Paragorgia   .
