Holotype, mature male, 8.9 mm (used for description and drawings of lateral view, antennae, gnathopods, mouthparts, pereiopods 3–7 and abdomen) (vial: ZMB 31309), Scary mound at 374–375 m water depth at 9.82286°S and 12.77381°E, South Atlantic off Angola, associated to hexactinellid sponges (Sympagella sp. and Aphrocallistes sp.) within a Lophelia pertusa gallery, leg. 22nd January 2016. Paratype “1”, mature female, 7.3 mm (used for description and drawings of lateral view, antennae, gnathopods, mouthparts, pereiopods 3–7 and abdomen) (vial: ZMB 31310), collected together with the holotype. Paratype “2”, immature male, 6.2 mm (vial: ZMB 31311), part of the bulk from ROV dive and could not be associated to a specific subsample, same data as holotype. Paratype “3”, mature male, 8.6 mm (vial: ZMB 31312), Valentine Mound at 500 m water depth at 9.72833°S and 12.71460°E, South Atlantic off Angola, associated to a hydroid which was attached to a dead Madrepora branch, 17th January 2016.

Pereonite 2 with a pair of dorsal acute projections anteriorly, one projection distally, and lateral acute projections (one in each side) near the coxa of gnathopod 2. Basis and ischium of gnathopod 2 with a distal projection. Propodus of gnathopod 2 very setose in males, provided with one proximal projection and 2 large distal projections. Distal article of the mandibular palp with 4 or 5 setae. Etymology. The species is named with reference to the cold-water corals habitat in which it was found. Description. Holotype male (8.9 mm). Lateral view (Figs 2 and 3). Head with dorsal acute projection. Pereonite 1 lacking projections. Pereonite 2 with a pair of dorsal acute projections anteriorly, and one projection distally, and lateral acute projections (one in each side) near the coxa of gnathopod 2. Pereonite 3 ... |
