Material examined: Taiwan: 1 male (53.0 × 31.2 mm) (NCHUZOOL 16506), Erzihliao Fishing Port, Kaohsiung, coll. YH Huang, 8 Jul. 2018; 1 female (44.4 × 26.0 mm) (NCHUZOOL 16511), Erzihliao Fishing Port, Kaohsiung, coll. YH Huang, 8 Jul. 2018; 1 female (57.8 × 33.7 mm) (NCHUZOOL 16571), Erzihliao Fishing Port, Kaohsiung, coll. YH Huang, 8 Jul. 2018.
Comparative material: Monomia haanii : 1 male (86.2 × 46.5 mm), 1 female (67.4 × 37.6 mm) (NCHUZOOL 16508), Erzihliao Fishing Port, Kaohsiung, Taiwan, coll. YH Huang, 8 Jul. 2018.
Diagnosis: Carapace transversely hexagonal, 1.7 times broader than long, surface densely pilose, with granular patches. All carapace ridges absent, except epibranchial regions with a pair of granulated ridges ( Fig. 10A View Fig ). Front with 4 rounded teeth, median 2 smaller than lateral, sulcus between median teeth continuing ventrally to triangular projection. Epistome with median tooth projecting beyond front. Supraorbital margins with 2 notches, lateral notch with tooth-like elevation before anterolateral tooth 1. Inner supraorbital angles tooth-like, with ventromesial ledge. Infraorbital margins with deep lateral notch. Anterolateral margins with 9 teeth, tooth 9 largest and projecting laterally ( Fig. 10A View Fig ). Basal antennal segment with lateral blunt lobe entering orbital cavity. Chelipedal merus with 4 spines on inner margin, 2 on outer margin; carpus with spine each on inner and outer margins; palm with 2 spines on dorsal surface. P5 with merus granulated on distal inner and outer margins. Maxillipeds 3 with merus longer than broad, anteroexternal angle strongly expanding to a prominent auriculiform structure. Male pleon with pleomere 6 longer than broad, lateral margins slightly convex. G1 with distal half slender and bent laterally, tip with spines ( Fig. 10B–E View Fig ).
Coloration: Carapace and chelipeds white with orange stripes, P5 with white band on propodus ( Fig. 3F View Fig ).
Distribution: New Caledonia; Australia; New Guinea; Taiwan (Erzihliao Fishing Port, Kaohsiung; Fig. 1 View Fig : no. 7); China (incl. Hong Kong; Hainan I.); Vietnam; Malaysia (Malay Peninsula); Singapore; Thailand; Myanmar; India ( Tranquebar); Sri Lanka; Madagascar; Mauritius; South Africa ( Sasaki 2019; this study).
Ecological notes: The habitats are 30–100 meters deep, with bottoms composed of sand, broken shells or pebbles ( Sakai 1976).
Remarks: Monomia gladiator ( Fabricius, 1798) is similar to M. haanii (Stimpson, 1858) , but can be distinguished by a suit of characters ( Windsor et al. 2019). Our specimens agree with M. gladiator by the following characters: (1) carapace with granular patches prominently and protruding in M. gladiator ( Fig. 3F View Fig ; Windsor et al. 2019: fig. 1C, D) (vs. smaller and less protruding in M. haanii ; Windsor et al. 2019: fig. 1F); (2) carapace with bright orange and white stripes in M. gladiator ( Fig. 3F View Fig ; Windsor et al. 2019: fig. 1C, D) (vs. uniformly tannish and reddish granules in M. haanii ; Windsor et al. 2019: fig. 1F); (3) distal propodus and dactylus of P5 without purple spot and area in M. gladiator ( Fig. 3F View Fig ; Windsor et al. 2019: fig. 1C, D) (vs. distal propodus with large purple spot and distal dactylus with purple area in M. haanii ( Windsor et al. 2019: fig. 1E, F); (4) The anterolateral margins of male pleomere 6 slightly convex in M. gladiator ( Windsor et al. 2019: fig. 3A–C) (vs. margins subparallel and converging anteriorly in M. haanii ; Windsor et al. 2019: figs. 2B, 3D–F); (5) G1 with distal half bent laterally, with angle below 90° in M. gladiator ( Fig. 10B–E View Fig ; Windsor et al. 2019: fig. 4A–D) (vs. angle bent almost at 90° in M. haanii ; Windsor et al. 2019: figs. 2C, 4E– H). With regard to the earlier records of “ M. gladiator ” from Taiwan, Ng et al. (2001 2017) considered they should be confused with M. haanii . As a result, this is the first confirmed record of M. gladiator from Taiwan.
