Material examined. Hainan Island: Hou Hai , coll. Yuli Sun, 5 May 2023, 1 female (7.21 × 6.10 mm), VX20230501; 3 m, coll. Yuli Sun, 29 November 2022, 1 male (11.35 × 10.59 mm), 1 female (13.77 × 12.01 mm), XY1102. Xiaodong Hai, 2–3 m, coll. Lecheng Qu, 5 December 2021, 1 female (11.21 × 10.07 mm), SY24. Lu hui tou, 3 m, coll. Sirenko , 19 November 2016 , 1 pre-adult (3.27 × 2.96 mm), SY94.

Geographical distribution. Across Indo-West Pacific region except the Hawaiian Islands ( Castro et al. 2004).

Remarks. Tetralia nigrolineata is the largest species of the genus recorded in the South China Sea. A unique specimen ( Fig. 6E View FIGURE 6 , VX20230501) that was collected possess pereiopods that are all white in color. We attempted to explore whether this coloration is of phylogenetic interest, and so we aligned its COI sequence with an individual of normal coloration (SY24) ( Fig. 6F View FIGURE 6 , XY1102). The result, however, suggests that they are conspecific. The phylogenetic tree ( Fig. 11 View FIGURE 11 ) and genetic distance ( Table 3 View TABLE 3 ) indicate minimal genetic divergence between the individual with a typical brown pattern ( Fig. 6F View FIGURE 6 , XY1102; Fig. 11 View FIGURE 11 , SY24) when compared to the specimen with white pereiopods ( Fig. 6E View FIGURE 6 ; Fig. 11 View FIGURE 11 , VX20230501).
