Figs 5 a–c, 21–27.

Description. Face and vertex dirty yellowish; band between 2 parallel narrow brownish bands on anterior margin of head, yellowish; pronotum and scutum yellow; basal triangles golden; forewings semitransparent and without patches. In some specimens, vertex, pronotum and scutum pale reddish. Color pattern of habitus, face and forewings as in Figs 5 a–c.

Vertex rounded and slightly elevated anteriorly. Forewings with RP diverging from MP’ in basal half; hind wings with CuA’’ situated in line with MP’’ or shifted to apex.

Abdominal apodemes reaching midlength of 5th abdominal sternite.

Male genitalia. Side of pygofer long; upper lobe long and narrowed with several rigid setae and horned protrusion terminally; central lobe nearly indistinguishable; lower lobe broad with numerous short setae marginally (Figs 21, 22). Subgenital plate with 2 basal short macrosetae, 5 peg-like setae and one twisted central apical seta (Figs 23, 24). Paramere with apex long and turned laterad and with subapical tooth minute and spur-like (Fig. 23). Aedeagal shaft arched and expanded near base with single short ventral process subapically (Figs 26, 27).

Notes. This species belongs to the germari group. It runs to Aguriahana daliensis Chou and Ma in the key to Aguriahana by Zhang, Chou and Huang (1992) but can be distinguished from the latter by its expanded aedeagal shaft (Figs 26, 27) and spur-like subapical tooth of the paramere (Fig. 23).
