Vertex with a brown stripe anteriorly connecting 2 lateral round black-brown patches. Pronotum with a central oval patch blackish and 2 pairs of lateral patches blackish, 2 brown bands between central and lateral patches. Scutum with 2 small light ochre patches on central area, triangles blackish brown. Scutellum with central area brownish, both sides of basal half yellow ochre and distal half brown ( Fig. 12 ). Forewing yellowish with 2 patches on clavus that one at base black-brown and the other brown band extended from central part to corium; patch at distal end of CuA vein brownish; brochosome field yellowish ( Figs 4 , 89 ).

Abdomen blackish, abdominal apodemes reaching center of 6th abdominal sternite ( Fig. 90 ). Male pygofer side subquadrate with a long digitiform appendage directed backwards on posterior margin ( Figs 91, 92 ). Subgenital plate without subapical protrusion ( Fig. 93 ). Paramere with apical 1/4 curved laterad nearly at right angle, subapical protrusion absent ( Fig. 95 ). Connective with stem nearly 2 times as long as lateral arms, central lobe absent ( Fig. 94 ). Aedeagal shaft arched and slightly expanded dorsally near base, with an arcuate dorsal extension subapically and a narrow ridged ventral appendage approximately on apical 1/2 ( Fig. 96 ).

Specimens examined. Holotype: ♂, CHINA, Hubei Province, Xingshan, Longmen river , 1300m, 13-IX-1994, coll. Fasheng Li. Paratype: 2♂, CHINA, Guangxi Province, Guilin Huaping National Nature Reserve , 500m, 10- VII-2019, coll. Junjie Wang.

Etymology. The specific name is derived from Latin word “politus which means “smooth, referring to the paramere without a subapical protrusion ( Fig. 95 ).

Notes. The new species resembles Agnesiella (A.) recurva sp. nov., but differs in the male pygofer side with a long digitiform appendage directed backwards and without rigid microsetae ( Figs 91, 92 ), and in the aedeagal shaft with a longer ridged ventral appendage ( Fig. 96 ).
