Figures 31 B–C and 32.

2006 Vestalenula cornelia n. sp. — Smith et al.: 1570 –1574, figs. 1–3.

Material examined: Three females from SY3, one female ( ECNU 20170414/HN42) dissected; one female from WN4, one female ( ECNU 20170417/HN41) dissected.

Dimension: Female, width 0.238 mm. LV, n = 2, length 0.433 –0.509 mm; height 0.217 –0.223 mm; RV n = 3, length 0.412 –0.487 mm, height 0.198 –0.204 mm.

Distribution: This species has been reported from Japan ( Smith et al. 2006) and Zhejiang ( Ma & Yu 2018) in China. This species was found in Sanya and Wanning on Hainan Island.

Remarks: The long keel on the RV indicates that it belongs to the danielopoli-group ( Rossetti & Martens 1998), and it was identified as V. cornelia based on the carapace length/height ratio (smaller than 2.2) and the P-abd. The P-abd of specimens found on Hainan Island is longer than those found in Japan. The carapace is smaller than in previous reports ( Smith et al. 2006).
