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 : 53-54

12. Aguriahana recurva sp. nov.

Figs 12 a–c, 84–92.

Description. Face and vertex yellowish; pronutum black excepting yellowish patch on central part; scutum in male black with distal part yellowish, in female scutum yellowish with basal triangles blackish brown. Color pattern of habitus, face and forewings as in Figs 12 a–c. Dorsum and termination of abdomen black; in male, subgenital plate ivory, with termination and inner margin blackish brown.

Vertex rounded. Forewings with RP diverging from MP’ before midlength of MP’; CuA’’ shifted toward wing apex.

Abdominal apodemes reaching end of 5th abdominal sternite ( Fig.84 ).

Male genitalia. Side of pygofer broad, upper lobe long with several sclerotized big teeth, central lobe short and broad with hind margin truncated, lower lobe with caudoventral protrusion finger-like ( Figs 85, 90 ). Subgenital plate with 2 basal macrosetae, 4 big peg-like setae and one slightly arched central apical seta ( Figs 87, 88 ). Paramere with caudal part equal to length of central and apical part and with subapical part broadened ( Fig.89 ). Aedeagus with one pair of long, sinuated and crossed processes with sculpture on apical part dorsally; shaft recurved distally with one long apical process just below gonopore on ventral side directed ventrad from base ( Figs 91, 92 ).

Measurement. Male 3.63 mm, female 3.81 mm long, including wings.

Notes. This species belongs to the stellulata group. It is very close to Aguriahana triangularis (Matsumura) but can be distinguished from the latter as follows: 1) patches on forewings adjacent to claval suture extended to the base of the claval area ( Fig.12 ), while in A. triangularis they are sbsent in the claval area; 2) side of male pygofer with upper lobe long and strongly sclerotized with big teeth terminally and with lower lobe having finger-like protrusion caudoventrally ( Fig.90 ), while in A. triangularis the upper and lower lobes are truncate terminally; 3) aedeagal shaft with apex rounded in lateral view ( Fig.91 ) while in A. triangularis it is angular.

Type material. Holotype, 3, CHINA. Yunnan Province: Dali, altitude 2500 m, Alnus , 12.xi.1999, coll. I. Dworakowska. Paratype, same data as holotype except, 5ƤƤ, altitude 2400 m; 13, Xinzhu Botanical Garden, Lijiang, altitude 2300 m, 16.xi. 1999.

Etymology. The specific name is derived from the Latin word “recurve” which refers to the recurved aedeagal shaft.
