Homolochunia valdiviae – Sakai, 1955: 106. – Sakai, 1976: 42. – Miyake, 1983: 197. – Nagai, 1994: 50. (not Homolochunia valdiviae Doflein, 1904 )

Material examined. 1 ovigerous female (34.1 × 26.4 mm), 1 female (11.6 × 8.5 mm) ( ZRC 2016.0198 ), station CP 4156, northeast of Macclesfield Bank , 16°09.80′N 114°58.73′E – 16°12.19′N 115°00.53′E, Taiwan, South China Sea, 503–511 m, trawl, coll. ZHONGSHA 2015 Cruise, 28 July 2015 .

Colour. The carapace and pseudorostral spines are brown to orange, with the rest of body dirty-white ( Fig. 24F ) (see also Ahyong et al., 2009: figs. 51, 52).

Remarks. The female from the South China Sea fits well with the description of H. gadaletae . The pseudorostral spines are long, slender, curved downward and possess two accessory spines distally. The subhepatic spines in this species are sharp, with the upper one twice the length of the second one; and the anterolateral and posterolateral spines are all strong and sharp. The ambulatory legs are very long and slender, with long dactyli; the P2–P4 meri all have five spines on the dorsal margin; and the fingers of the P5 pseudochela are long and slender.

Remarks. Ng & Kumar (2015) recently reviewed Moloha in describing a new species from India and noted that the correct date for the genus should be “ Barnard, 1946 ”.
