Subgenital plate broad at base with apical 1/3 widen and folded dorsad, with 4 macrosetae and some rigid microsetae laterally near base and numerous microsetae apically and laterally on folded part ( Figs 52, 53 ). Paramere long and gradually narrowing distally with both ends nearly equal length, central part expanded ( Fig. 54 ). Connective with central lobe developed and extended beyond lateral feet. Aedeagal shaft slender and straight; dorsoatrium straight in lateral view ( Figs 54, 55 ).

Examined type materials. Holotype: Male, CHINA, Yunnan Province, Menglun , 101.28°E, 21.92°N, 9 July 1999, coll. Irena Dworakowska. Paratype: 2 Males, same data as holotype . 4 Males, Yunnan Province, Xishuangbanna , 100.91°E, 22.01°N, 8 July 2017, coll. Weijian Huang.

Notes. The new species is similar to Takagioma gladius sp. nov in body coloration and the shape of aedeagus, but can be distinguished by the curved pygofer hook, centrally widened paramere and the narrow base of aedeagus.

Etymology. The specific epithet is derived from Latin adjective “ curvatus ”, which means “curved”, referring to the strongly curved pygofer hook.
