4. Aguriahana digitata sp. nov.

Figs 4 a–c, 13–20.

Description. Face ivory. Vertex, pronotum and scutum yellowish; triangular patch on centre of pronotum and basal triangles yellow; in lateral view, horizontal narrow band on anterior margin of vertex extending to side of pronotum, blackish. Color pattern of habitus, face and forewings as in Figs 4 a–c.

Vertex extended anteriorly. Forewings with RP diverging from MP’ before midlength of MP’; hind wings with CuA’’ shifted toward wing apex.

Abdominal apodemes reaching end of 6th abdominal sternite.

Male genitalia. Side of pygofer short; upper lobe long and narrow with minute tubercles, few teeth and several rigid setae terminally; central lobe broad and round terminally with numerous short rigid setae; lower lobe narrow (Figs 13, 14). Subgenital plate with one basal macroseta, 4 peg-like setae and one twisted central apical setae (Figs 15, 16). Paramere with apex slightly twisted and with minute subapical tooth (Fig. 17). Aedeagal shaft finger-like with pair of long lateral processes exceeding apex of shaft (Figs19, 20).

Measurement. Male 2.15 mm long, including wings.

Notes. This species belongs to the sinica group and resembles Aguriahana sichotana (Anufriev) in the male genitalia. It differs from the latter species in lacking the expanded base of the aedeagal shaft and processes exceeding the apex of the shaft (Figs 19, 20); moreover, the color pattern of the forewings in the new species is bright and complex (Fig. 4), while A. sichotana lacks patches on the forewings.

Type material. Holotype, 3, CHINA. Yunnan Province: Mt. Nangong, Mengla, altitude 1100 m, 14.xii.1999, coll. I. Dworakowska. Paratype, 13, same data as holotype except 13.xii.1999.

Etymology. The specific name is derived from the Latin word “digitas” which refers to the finger-like aedeagal shaft.
