Material examined. CHINA: 2♀ (HBUARA#2022-133), Hainan Province, Sanya City, Fenghuang Mount, HaishiShanmeng Scenic Spot (18.253333°N, 109.545722°E, 369 m), 22.VII.2022, leg. L. Zhang and W. Wang. 1♂ (HBUARA#2023-123), Hainan Province, Sanya City, Fenghuang Mount, HaishiShanmeng Scenic Spot (18.25153947°N, 109.55131888°E, 365 m), 4.VI.2023, leg. W. Wang.

Diagnosis. The males of this species resemble those of E. panache , but can be distinguished by the straight, anteriorly pointed distal part of embolus (vs curved and transversely pointed in E. panache ) (cf. Figs 9B , 13A with Figs 12B , 13C ). The females can be distinguished from all Echinax species by: 1) carapace without radial stripes and with long median Y-shaped stripe ( Fig. 8C ); 2) the dorsum of abdomen with cardiac pattern ( Fig. 8C ); and 3) the ventral abdomen with cardiac pattern ( Fig. 8D ).

Description. See Deeleman-Reinhold (2001).

Distribution. China (Hainan).
