Cladocarpus keiensis Schuchert, 2003: 231 , fig. 74.

Material examined

PACIFIC OCEAN • 1 colony, ca 15 cm high with a 2.3 cm-long side branch, hydrorhiza and gonosome missing; off New Caledonia, stn DW4763 ; 23°17ʹ S, 168°15ʹ E; 192–260 m; 27Aug. 2016; KANACONO leg.; MNHN-IK-2015-543 .

Remarks

For a description of this species, refer to Schuchert (2003), who documented gonocladia bearing incipient gonothecae only, while the mature ones are still to be described. According to the present material, the plate-like intrahydrothecal septum is pierced in its center by a large, rounded foramen. The passage of the hydranth takes place in front of the septum and its body passes between the two lateral, arched perisarcal ridges.

Distribution

Kei Islands, Indonesia ( Schuchert 2003), New Caledonia (present study).
