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 ).

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 ).
