Elasmopus sp. A ( aff. molokai / piikoi )
Elasmopus sp. A (aff. lapu) Moore, 1990.
Material examined
Cape D’Aguilar, Hong Kong Island, on Gelidium pusillum , two specimens, one male, one damaged and indeterminate, NHM Reg. Nos. 2004.2947–2948.
Remarks
The most distinctive characteristic of this species is the 1-articulate, lanceolate, setose flagellum of antenna 2. Gnathopod 2 of this species resembles that of Elasmopus molokai Barnard, 1970 , and E. piikoi Barnard, 1970 . However, Elasmopus sp. A lacks the proximal palmar defining process. Uropod 3 outer ramus apex is spinose, closer to Elasmopus molokai than E. piikoi . This species is probably synonymous with Elasmopus sp. A of Moore (1990) since both the current material and Moore’s species lack the castellated posterior margin of pereopod 7 basis and the dense setation of the posterior margin of male gnathopod 2 propodus.
