Pygofer sides with two bands of setae widely separated, one on ventral margin basally, and other one on posteroventral margin, ventral appendage of pygofer slightly bent and curved dorsolaterad ( Fig. 112 ). Paramere slender, with row of microsetae on subapical part ( Fig. 115 ). Aedeagus subapical area dilated ( Fig. 116 ), ventral lamella with irregularly serrate flange attenuated ventrally ( Fig. 117 ).

Type material. Holotype, ♂, National Forest Park of Daweishan , Yunnan Province, alt. 2048 m, 22 May 2015, coll. Bin Yan. Paratypes, 1♀, same data as the holotype ; 2♂♂ 1♀, Cangshan Mountain, Dali city, Yunnan Province, 13 Aug. 2012, coll. Wenqin Liang ; 1♀, Cangshan Mountain, Dali city, Yunnan Province, 13 Aug. 2012, coll. Meng Jiao ; 5♂♂, Jinping National Natural Reserve , Yunnan Province, alt. 1670 m, 19 May 2015, light trap, coll. Bin Yan ; 3♂♂, Jinping National Natural Reserve , Yunnan Province, alt. 1670 m, 19 May 2015, coll. Bin Yan.

Etymology. The species name is derived from the Latin word sinuata , meaning “wave, bent or curved”, and refers to the ventral lamella of the aedeagus.

Remarks. This species resembles Agnesiella (D.) latusa Yan & Yang, 2016 in having a similar pygofer and aedeagus, but differs in the color pattern of its crown, body color, and in the shape of the ventral lamella of the aedeagus. The MP´´+ CuA´´transverse veins of the hind wing also are positioned differently ( Figs 63, 65 ).
