Based on female, 5.0 mm, AM P75471. Sternal spines absent. Gnathopods 1–2coxa a little deeper than that of male.  Habitat.Among coral rubble.   Remarks.This species is very close to  G. ruffoi Myers, 1975. It is characterised by the presence of an extremely long distoventral spine on uropods 1–2, that is equal to, or exceeds the length, of the outer ramus. No other aorid amphipod is known to have such an excessively long distoventral spine. The peduncle of uropod 3 has a spine at the inner distal margin in  G. longispinosusnot present in  G. ruffoi, and there are slight differences in the proportions of the carpus and propodus of the male gnathopods 1-2, the carpus of  G. longispinosusbeing a little longer than that of  G. ruffoi. The male gnathopod 1 palm is less convex in  G. longispinosusthan in  G. ruffoi.   Distribution.  Australia. Queensland: Palfrey Island, Lizard Island (current study).  China. Hainan Province: Yalong Bay, Sanya ( Ren 2006).  Papua New Guinea. MadangLagoon ( Myers 1995).
