Description.

Forewing long and elongate apically and relatively wide, with oblique apical margin, near triangular in the tip, with distinctly dark or gray pigmented transverse bands, irregular speckles and longitudinal stripes, mainly behind the nodal line and postnodal area. Length about 34.04 mm, width about 14.54 mm, with the ratio of length/width approximately 2.34; costal margin broad, length about 21.36 mm; clavus arched, small and broad (length 15.06 mm, maximum width 4.55 mm), with conspicuous light pigmented bands. Nodal line situated in the middle of forewing. Crossvein r-m absent; branched into ScP+R and M at basal 0.17 wing length. Stem ScP+R bifurcated into ScP+RA and RP at basal 0.47 wing length; vein ScP forked with RA at nodal line, and terminating at nodus; RA with three branches, RA1 short and nearly straight, RA2 and RA3 long and slightly sinuous, RA2 parallel to RA3; branch RA3 connected with vein RP by the crossvein ir. Crossvein ir at the middle of nodal line and outer margin. Vein RP strongly curved, running along the nodal line for a distance; vein M1 strongly curved and fused with RP for a distance, then subparallel to M2; stem ScP+R relatively shorter than stem M. Stem M forked into M1+2 and M3+4 at basal 0.15 wing length, and at different level. M1+2 branched into M1 and M2 at basal 0.33 wing length; M3+4 bifurcated into M3 and M4 at basal 0.21 wing length; stem CuA long and initially sinuous, fusing with nodal line and running along with nodal line for a distance, then branched into CuA1 and CuA2 just beyond nodal line. CuA1 long and relatively straight; CuA2 short and obviously sinuous; CuP long and straight. A1 sinuous. A2 short and strongly curved; eleven apical cells.

Etymology.

The species name refers to Prof. Xiaoting Zheng, who is the founder of Shandong Tianyu Museum of Nature and donated the type material.
