Type material

Holotype, female, Jianfengling (18.7N, 108.8E), Ledong County, Hainan Province, China, April 1994, Liao Cong­Hui leg.

Diagnosis

The new species is similar to E. prima Zabka, 1985 (221, figs 165–169) in body form and markings, but can be distinguished from the latter by: (1) epigynum with a large distinct cap­shaped marking(Fig. 5), absent in E. prima ; (2) atrium much larger and posteriorly located, anteriorly located in E. prima ; (3) spermathecae tube­shaped in the new species, pear­shaped in E. prima ; (4) copulatory ducts much shorter and merged in the new species, but separated in E. prima .

Etymology

The species is named after Chong­Hui Liao, who collected the type specimen.
