Material examined: Three females and two female valves from WN5, two females (ECNU 20170417/HN35–36) dissected; 18 females from 11DZ17, one female (ECNU 20171114/HN45) dissected.

Dimensions: Female, LV, n = 2, length 1.069 –1.073 mm, height 0.625 mm; RV, n = 2, length 1.041 –1.044 mm, height 0.602 mm.

Description: Carapace sub-elliptical with four purple bands. Surface of carapace slightly reticulated (Fig. 11A). LV overlapping RV both anteriorly and posteriorly. In lateral view, anterior margin more rounded than posterior. Greatest height anterior of mid-length. LV with inner groove along margins except dorsal margin (Fig. 11B). Calcified inner lamella with inner list anteriorly. Two tooth-bristles on third endite of Mx slightly serrated. Basal segment of L6 with two d setae (Fig. 10A). UR attachment well-developed, with Triebel’s loop situated at middle of dorsal and ventral branches (Fig. 10B).

Distribution: This species has been found in the Philippines, Malaysia and Indonesia (Victor & Fernando 1981c) and Thailand (Savatenalinton & Martens 2010). This species was found in Wanning and Danzhou on Hainan Island.

Remarks: This species is assigned to the genus Pseudostrandesia because of the absence of seta d on L5 and the mid-position of the Triebel’s loop on UR attachment (Fig. 10B).
