Huang, Min & Zhang, Yalin, 2011, New species and new records of the leafhopper genus Aguriahana Distant (Hemiptera: Cicadellidae: Typhlocybinae) from China, Zootaxa 2830, pp. 39-54 : 52-53

11. Aguriahana dilatata sp. nov.

Figs 11 a–b, 76–83.

Description. Face and vertex yellowishish. Rounded patches on lateral anterior margin of vertex and lateral distal angle on pronotum and scutum excepting basal yellowish angle, blackish brown ( Fig. 11 a). Color pattern of forewings as in Fig.11 b.

Vertex rounded anteriorly. Forewings with RP diverging from MP’ at midlength of MP’; hindwings with MP’’ situated on level of CuA’’.

Abdominal apodemes reaching basal 1/3 length of 5th abdominal sternite.

Male genitalia. Side of pygofer short with numerous short setae on disc, upper lobe narrow and with several rigid setae at hind margin and 2 big teeth terminally, lower lobe with hind margin sinuated ( Figs 76, 77 ). Subgenital plate broad with 2 basal macrosetae, 4 peg-like setae and one twisted central apical setae ( Figs 78, 79 ). Caudal part of paramere long with subapical tooth rounded ( Fig.80 ). Aedeagus short with one pair of straight long process twisting subapically, shaft expanded near base ventrad and dorsad ( Figs 82, 83 ).

Measurement. Male 3.54 mm long, including wings.

Notes. This species belongs to the stellulata group. It is similar to Aguriahana niisimai (Matsumura) in the color pattern of the forewing, but differs from the latter species as follows: 1) subgenital plate with 2 basal macrosetae ( Fig.72 ); 2) subapical tooth of paramere round, not spur-like ( Fig.80 ); 3) aedeagal shaft straight and short with one pair of basal process ( Figs 82, 83 ).

Type material. Holotype, 3, CHINA. Sichuan Province: Mt. Emei, altitude 600 m, 2.xi.1999, coll. I. Dworakowska.

Etymology. The specific name is derived from the Latin word “ dilatata ” which refers to the basally expanded aedeagal shaft.
