Type material.

Holotype ♂: China: Jiangxi: Jinggangshan City: Ciping Village, Shiyan Cave, N26°36'11", E114°12'46", elevation: 977 m, 3.I.2013, Y.C. Li. Paratypes: 5♀, same data as holotype; 2♀, China: Jiangxi: Jinggangshan City: Ciping Village, Shiyan Cave, N26°36'11", E114°12'46", elevation: 977 m, 4.V.2013, Y.F. Luo and J.C. Liu.

Etymology.

The specific name is a patronym in honor of the collector Yufa Luo; noun (name) in genitive case.

Diagnosis.

The male can be distinguished from all other Platocoelotes by the distinct dorsal conductor apophysis and two sheet-shaped outgrowths of the anterior conductor apophysis (Fig. 1 A–C). The female can be distinguished from all of the other Platocoelotes , except Platocoelotes globosus Xu & Li 2008, by having a rounded epigynal atrium and can be distinguished from Platocoelotes globosus by anteriorly located epigynal hoods and distinct spermathecal heads (Fig. 2 A–B; Xu and Li 2008: figs 9-10).
