Material examined: Taiwan: 3 males (20.3–26.9 × 12.0– 15.8 mm), 2 females (23.2–23.5 × 13.2–13.7 mm) (NCHUZOOL 16530), Zuoying, Kaohsiung, Jun. 2001; 1 male (26.4 × 16.4 mm) (NCHUZOOL 16532), Dalinpu, Siaogang, Kaohsiung, 12 May 1997; 1 female (20.7 × 11.9 mm) (NCHUZOOL 16559), Erzihliao Fishing Port, Kaohsiung, coll. YH Huang, 8 Jul. 2018; 1 male (25.1 × 14.7 mm), 1 ovig. female (26.8 × 15.9 mm) (NCHUZOOL 16594), Dalinpu, Siaogang, Kaohsiung, Jun. 2001.
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. 12A View Fig ). Front with 4 rounded teeth, median 2 smaller and more protruding than lateral ( Fig. 12A View Fig ). Supraorbital margins with 2 notches, inner supraorbital angle tooth-like, with ventromesial ledge. Anterolateral margins with 9 teeth, tooth 9 largest ( Fig. 12A View Fig ). Junction between posterolateral and posterior margins tooth-like ( Fig. 12A View Fig ). Basal antennal segment with a lateral blunt lobe entering orbital cavity. Chelipeds granulated and pilose, merus with 3 blunt spines on inner margin, outer margin with 1 spine; carpus with spine each on inner and outer margins; palm with 2 granulated ridges and 1 spine on dorsal surface, outer surface with 3 ridges. P5 with merus granulated on inner margin. Maxillipeds 3 with merus longer than broad, anteroexternal angle strongly expanding to a prominent auriculiform structure. Male pleon with pleomere 6 trapezoidal, longer than broad. G1 smooth, distal half slender and bent laterally ( Fig. 12B–E View Fig ).
Distribution: Hawaii; Australia; Indonesia (Makassar); Guam; Palau; Philippines; Nansha Is.; Taiwan; Japan (incl. Ryukyus); China (incl. Hong Kong; Hainan I.); Vietnam; Thailand; India; Sri Lanka; Maldives; Gulf of Aden; Gulf of Oman; Seychelles; Tanzania; Madagascar ( Sasaki 2019; this study).
Ecological notes: Specimens were collected by trawling at about 30 meters deep (this study).
Remarks: Chou et al. (1999) recorded the name “ Portunus tuberculosus ” from Taiwan, but Ng et al. (2001 2017) considered it should be a typographical mistake of Portunus trituberculatus . As a result, Xiphonectes tuberculosus is the first confirmed record from Taiwan in our study.
