Remarks. The genus was reviewed by Richer de Forges & Ng (2012) and contains four species: G. lappacea (Rathbun, 1918) from southern Australia (type species), and three species from the Philippines, G. gilloloensis (Rathbun, 1916), G. polita (Griffin & Tranter, 1986), and G. takedai Richer de Forges & Ng, 2012.Published as part of Lee, Bee Yan, Forges, Bertrand Richer De & Ng, Peter K.

Remarks. Laubierinia currently includes two species, L. carinata (Griffin & Tranter, 1986) (type species), and L. nodosa (Rathbun, 1916). Laubierinia is morphologically close to the IWP Rochinia but differs by a more rounded carapace (versus pyriform carapace in Rochinia), short and flattened pseudorostral spines (versus long, slender and more cylindrical pseudorostral spines in Rochinia), and the presence of large distinct granules on the hepatic and branchial regions (versus with hepatic and branchial spines in Rochinia) (see Richer de Forges & Ng 2009a).Published as part of Lee, Bee Yan, Forges, Bertrand Richer De & Ng, Peter K.

CP 1575, 19° 41.75 ’S – 174 ° 21.21 ’W, 232–295 m, 11 June 2000: 1 male (11.1 x 12.2 mm) (MNHNB 30733). – Stn. CH 1579, 19° 41.88 ’S – 174 ° 26.05 ’W, 332 m, 11 June 2000: 5 males (14.0 x 17.0 mm, 16.2 x 24.0 mm, 17.2 x 22.2 mm, 14.0 x 16.0 mm, 13.2 x 16.8 mm), 1 female (16.8 x 22.9 mm), 3 juveniles (12.2 x 15.6 mm, 14.0 x 16.0 mm, 11.0 x 13.0 mm) (MNHNB 30734). – Stn. CP 1641, 21°09.31’S – 175 ° 22.04 ’W, 395 m, 21 June 2000: 3 males (15.1 x 22.7 mm, 14.1 x 19.8 mm, 9.0 x 13.0 mm) (ZRC 2008.0745). Remarks. This species belongs to the group of Cyrtomaia species which have a preocular spine. The first species of this group that was described, C. murrayi Miers, 1886, was collected by the Challenger Expedition in Indonesia but has since been reported from Philippines, Taiwan and Japan (Sakai 1976; Guinot & Richer de Forges 1986; Ng & Huang 1997; Richer de Forges & Ng 2007 b). Guinot and Richer de Forges (1982 a) described another smallsize species from New Caledonia, C. ericina. The main differences between these two species are the presence of one supraorbital sharp spine in C. murrayi (a small tubercule in C. ericina) and the presence of spinules on P 4 and P 5 carpi in C. murrayi (smooth in C. ericina) (Guinot & Richer de Forges 1982 b: 18, 20, figs. 6, 8A). The material examined of C. ericina is from Tonga, more than 2000 km to the east of New Caledonia. A detailed study of the specimens from Tonga attributed to C. ericina and numerous specimens of C. murrayi from the Philippines reveals more differences. There is one large supraorbital spine in C. murrayi (in contrast to a small spine in C. ericina), the ambulatory legs are relatively stronger and more spiny in C. murrayi than in C. ericina, the P 3 propodus of C. murrayi has a row of very long spines on the lower border (only seven relatively shorter spines in C. ericina), the P 3 carpus has 18 spines on the upper border (eight in C. ericina), the P 4 carpus is spiny along the entire upper border (only three small spines in C. ericina), the P 5 carpus is spiny (smooth in C. ericina), and the basal antennal article has three teeth (two in C. ericina).Published as part of Forges, Bertrand Richer De & Ng, Peter K.

Material examined. Vanuatu: Espiritu Santo I., SANTO 2006, stn. AT 10, 15°41.1’S 167°00.5’E, 509–659 m, 17 September 2006: 1 male (12.8 x 11.2 mm) (MNHN-B31278).— Stn. AT 72, 15°44.1’S 167°03.3’E, 618–722 m, 7 October 2006: 1 female (15.1 x 12.9 mm, photographed) (ZRC 2008.0976). Remarks. Homola coriolisi, originally described from New Caledonia (Guinot & Richer de Forges 1995), is here recorded for the first time from Vanuatu. It is a relatively small-size species close to H. ikedai Sakai, 1979, but differs mainly in having a proportionately wider carapace than H. ikedai and the orientation of the anterolateral spines being less divergent and more gently curved in H. coriolisi. From the available data, H. coriolisi also apparently lives at somewhat greater depths (exceeding 400 m and up to 722 m) than H. ikedai (200–650 m) (see Richer de Forges & Ng 2007). The carapace of live specimens is marbled yellow with red patches, the ambulatory legs are banded red and yellow, and the chelae are white, contrasting with the yellowish-brown of the rest of the body (Fig. 15A).Published as part of Forges, Bertrand Richer De & Ng, Peter K.

Remarks. Homolochunia gadaletae, which was described by Guinot and Richer de Forges (1995) from Japanese material originally referred to H. valdiviae, has also been recorded from Taiwan by Huang & Hsueh (1998). The species lives in relatively shallow depths of 150 to 250 m.Published as part of Forges, Bertrand Richer De & Ng, Peter K.

(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 ”.Published as part of Ng, Peter K.
