Figs 5, 6, 11, 13, 15–23
Description. Coloration. Yellow brown with dark to black markings on head and thorax. Vertex (Fig. 5) with two round spots closer to adjacent eyes than to each other. Face (Fig. 11) yellowish brown with genae black stripe along outer margin of frontoclypeus; Eyes brown and ocelli pale yellow. Pronotum (Figs 5) yellowish brown with six blackish brown maculae: two small macula on anterior margin, two large ones on median portion, and another pair on lateral margin. Scutellum (Fig. 5) yellowish brown with basal triangles, blackish brown, inverted Y-shaped macula contiguous with median macula. Forewings (Figs 6, 14) with outer claval vein (2A vein) grayish white.
Male genitalia. Pygofer (Fig. 17) elongate triangular, in lateral view, narrow at base, posterodorsal margin expanded, caudal margin rounded apically and ventral margin nearly straight. Anal collar elongate with hookshaped process. Subgenital plate (Figs 17, 18), in lateral view, gently curved dorsad; in ventral view, gradually narrowed to finger-like apex, dorsal margin of apical half with fine setae. Style (Fig. 19) with apophysis gradually narrowed to apex bearing approximately 11-12 lateral setae. Connective (Figs 20, 21) laminate, slightly longer than wide. Aedeagus (Figs 22, 23) with preatrium and dorsal apodeme poorly develop; dorsal margin of aedeagal shaft slightly curved dorsally, apex with several apical processes: a pair of bifurcate processes with branched process arising from ventral margin of base and shorter than dorsal arterial process, a ventral long process arising on posterior margin of gonopore and tapered to apex; gonopore at apex between bases of apical processes.
Female. Unkown.
Measurements (mm). Male: body length 6.0, face length 1.65, width 2.0; distance between ocelli 0.57; distance from ocellus to eyes 0.4; medial length of pronotum 0.86, width 1.87; scutellum length 1.17, width 1.42; length of anteclypeus 0.42, width across base 0.3, width across subapex 0.33.
Material examined. Holotype: male, China, Sichuan Province, Mianyang City, 20.xii.2017, Bin Zhang. Paratype: 1 male, same date as holotype.
Host plant. Unknown.
Distribution. China (Sichuan).
Remarks. Hyalinocerus mianyangensis resembles H. nigrimaculatus in having a similaraedeagus and male pygofer, but differs from the latter in having the face with longitudinal irregular maculae, the ventral margin of the aedeagal shaft slightly curved dorsally and then nearly straight, and the apex with the ventral unpaired process longer than dorsal branched processes. It also closely resembles H. qianensis in pattern, but differs in the coloration, the structure of two claval veins and larger number of hind tibial macrosetae PD 24-25, AD 13 (PD 21- 22, AD 10 in Hyalinocerus qianensis).
Etymology. The specific epithet refers to the type locality, Mianyang City belong to Sichuan Province, China.
