Figures 33 and 34.

Material examined: Two females from JFL15, one female (ECNU 20170413/HN43) dissected.

Dimension: Female, RV, n = 1, length 0.452 mm, height 0.229 mm.

Description: LV overlapping RV both anteriorly and posteriorly (Fig. 33A). Posterior end wider than anterior. Dorsal margin slightly arched. Keel on RV short (Fig. 33B). Ventral seta on the third segment of A1 absent (Fig. 34A). Exopodite on A2 with one long seta. Both claws on terminal segment (GM and Gm) approximately same lengths (Fig. 34B). UR base narrow. P-abd short and without any seta (Fig. 34C).

Distribution: This species was found in Jianfengling National Forest Park on Hainan Island.

Remarks: According to the following characters: L/H of the carapace smaller than 2.2, P-abd without seta, third segment of the A1 without ventro-apical seta, shape of the UR base, this species is similar to Vestalenula spec. D, Rossetti & Martens, 1999, but this species can be distinguished from Vestalenula spec. D by the following characters: the dorsal margin is extremely straight in Vestalenula spec. D but slightly arched in Vestalenula sp. from Hainan; claw Gm on the A 2 in Vestalenula sp. from Hainan is much longer than that of Vestalenula spec. D. (Pinto et al. 2013; Rossetti & Martens 1999).

Only two females were collected in April 2017 during our two collection trips. The number of specimens is insufficient to provide a full description of this species.
