Description. Both Komai & Saito (2006) and Jiang et al. (2015) have provided detailed description of the species.

Coloration. Entire body including eyes semitransparent. Internal organs inside carapace yellowish. Distribution. Loyalty Islands, New Caledonia, Vanuatu, South China Sea and southwestern Taiwan, at depths of 437–1300 m; associated with hexactinellid sponges.

Remarks. The Taiwanese material was all from the inside of hexactinellid sponges and sometimes more than a pair of specimens could be found inside a single sponge. The sponges were collected from rather soft sandy mud bottoms but without any sign of chemosynthetic environment. Jiang et al. (2015) reported that their specimens were collected from a cold vent at 22°7.30’N, 119°17.20’’E in the South China Sea. Actually the cold vent Jiang et al. (2015) referred to is the Formosa Ridge cold seep, dominated by the galatheoid crab Shinkaia crosnieri Baba & Williams, 1998 (see Baba et al. 2009; Lin et al. 2013; Li 2015; Yang et al. in press). We have performed many biodiversity surveys on the Formosa Ridge ( Lin et al. 2013; Yang et al. in press) but no sponges have been found directly on the cold seep, though many hexactinellid sponges were collected during trawl surveys in nearby areas (22°07.75’– 22°19.32’ N, 119°59.96’– 120°03.30’E, see “Material examined”). A communication with Xinzheng Li, corresponding author of Jiang et al. (2015), reveals that the types of G. jiaolongi was actually collected outside the cold seep site in an area not affected by chemosynthesis. Thus, G. spinulatus should not be considered as being related to chemosynthetic environments. Nevertheless, the associated sponges of the Taiwanese material of G. spinulatus have a general appearance very similar to the host sponge of G. jiaolongi shown in Jiang et al. (2015: fig. 7).
