MATERIAL. Holotype – ♂, China: Hunan Prov., “Jiucai Ling”, 25º32ʹN, 111º22ʹE,

~ 1300 m, VII.2006, V. Sinyaev, S. Sinyaeva ( ZIN). Paratype – 1 ♂, same data as for holotype .

DESCRIPTION. Male (holotype). Coloration and structure of body very similar to those of nominotypical subspecies (Xia & Liu, 1988: figs 1–3) but with following characteristic features: body yellowish with dark brown both large dorsal area on head behind lateral ocelli

(this area also with narrow dark median stripe running almost to rostral apex, and with three longitudinal greyish brown spots between eyes) and wide median band on pronotal disc, with brown small and sparse spots on tegmen along median line and along costal edge, with light greyish brown stripe along anal tegminal edge, and with very light brown last tergite and cerci ( Figs 36–39 ); last tergite with large posteromedian notch which slightly deeper and less widely rounded in its anterior part than in X. (A.?) i. incisus Xia et Liu, 1988; cerci somewhat longer and clearly wider than in latter subspecies (they longer than visible lateral part of last tergite, and their proximal parts in contact with each other, if cerci directed backwards or backwards/medially; vs. they shorter than lateral part of last tergite, and their proximal parts clearly not contacting with each other in such cercal position) as well as without distinct lateral notch near apical part ( Figs 37–39 ); genital plate as in Figs 38, 39 .

Variations. Second male without distinct light greyish brown stripe along anal tegminal edge and with almost straight posterior edge of genital plate between styles.

Female unknown.

MEASUREMENTS. Length (in mm). Body 10; body with wings 20–21; pronotum 3.5–

3.7; tegmina 16–16.8; hind femora 10–10.5.

COMPARISON. The new subspecies differs from nominotypical one in the characters of the male last tergite and of the male cerci listed above.

ETYMOLOGY. This subspecies name originates from the Latin prefix “lati-” (wide) and the Latinized Greek morphological term “cercus” due to the shape of the male cerci.
