description: <i>Homologenus namakae</i> Ng, 2016 (Fig. 13, 14) <i>Homologenus namakae</i> Ng, 2016: 48, figs. 1–3. <b>Material examined</b>. <b>Hawaiian Islands</b>: Holotype female (14.3 × 12.7 mm) (SIO C3517), station SS-72, 137-DB, south of Kaua'i, 21º58.13'N 159º16.81'W, 823 m, coll. RV Sea Scope, box dredge, 9 July 1972.— Others: 1 female (13.4 × 11.8 mm) (USNM 128585), Molokai, north coast, 1009.5–1479.5 m, coll. RV Albatross, trawl, 17 April 1902.—1 ovigerous female (14.6 × 12.6 mm) (USNM 128586), French Frigate Shoal, 23º49'30"N 166º25'55"W, 726–757 m, coll. RV Albatross, tangle net, 29 May 1902.— 1 male (carapace partially crushed, length 10.9 mm) (USNM 128587), off Kaua'i, southeast of Ukula Point, 929–1018.6 m, coll. RV Albatross, trawl, 17 June 1902. <b>Remarks</b>. Ng (2016) described <i>Homologenus namakae</i> from one female from Kaua'i but we have since found three lots in the USNM from Hawai'i that are also referable to this species; they had been previously been identified as <i>H. malayensis</i> Ihle, 1912. Ng (2016: 52) placed <i>H. namakae</i> in a group of with <i>H. asper</i> Zarenkov, in Zarenkov &amp; Khodkina, 1983, <i>H. malayensis</i> Ihle, 1912, <i>H. levii</i> Guinot &amp; Richer de Forges, 1995, and <i>H. donghaiensis</i> Chen, 1986), all of which are distinguished by the absence of a spine at the base of the large anterolateral spine and the presence of only one spine on the distal margin of each P2–P4 merus. <i>Homologenus namakae</i>, however, can be eas- ily distinguished from the other species in this group by the complete absence of a spine or tubercle on the gastric region and having relatively short antennal and subhepatic spines. The male of the species is figured here for the first time (Fig. 14 C–E). The taxonomy of <i>H. malayensis</i> s. str. was also recently revised by Ng &amp; Richer de Forges (2017) who recognised two allied new species from the South China Sea. <b>Distribution</b>. Known only from the type locality around Kaua'i (Ng, 2016).
