Coloration. Color notes accompanying specimen MNHN-Na 11968: carapace and abdomen whitish with numerous pink chromatophores; tail fan with reddish spines; eyes black; scaphocerite transparent outlined in pink; antennae transparent outlined in white; mouthparts and legs salmon pink; and third pereiopod whitish mostly with pink chromatophores and pink outline, dactylus mostly pink.

Hosts. This species has been found several times in the sponge Pheronema semiglobosum .

Remarks. This species was thoroughly described by Saito & Komai (2008) and is not redescribed here. The mouthparts are illustrated here as well as some variation in the spination of the third pereiopod ( Figs. 4 B–H, 4K– M). Saito & Komai (2008) also reported on additional records of this species from New Caledonia (Jumeau Bank, Norfolk Ridge, and Banc Stylaster).
