Neolarnaca vera aurelostria subsp. nov.

( Figs 1–7 )

Male. Body medium-sized. Micropterous. Fastigium verticis about 1.8 times the width of scape, lateral margins not raised ( Fig. 1 ). Eyes elongate, oval. Ocelli small, subcircular. Scape equal to the length of eyes, but shorter than pedicel and first segment of flagellum combined; pedicel as long as first segment of flagellum. Pronotic anterior margin slightly projected and posterior margin almost straight; lateral lobes longer than height ( Figs 2–3 ). Fore coxae with 1 small spine. Fore femora absent; median femora unarmed spines on ventral surface; hind femora with 4–5 inner and 4–6 outer spines on ventral surface. Median tibiae with 1 inner dorsal spur and 5 pairs of ventral spurs (including 1 pair of apical spurs), the apical ones obviously shorter than the others ( Fig. 5 ). Hind tibiae with 6 pairs of dorsal spines, 1 pair of dorsal apical spurs, 2 pairs of ventral apical spurs and 1 pair of ventral subapical spurs. Tegmina reaching the posterior margin of third abdominal tergite. Hind wings shorter than tegmina. Second abdominal tergite with 1 row of oblique stridulatory teeth; third abdominal tergite with 2 parallel rows of stridulatory teeth ( Fig. 4 ). Ninth abdominal tergite with 1 pair of spines, which downwards and forwards pointing, its apex acute ( Fig. 7 ). Tenth abdominal tergite membranous. Cerci short, nearly cylindrical. Anterior margin of subgenital plate almost straight, posterior margin with 1 triangular concavity in the middle. Styli stout, cylindrical, apices obtuse ( Fig. 6 ).

Female. Unknown.

Coloration. Body light brown. Eyes brown. Pronotum dark brown, with narrow yellowish brown edges and 1 wider yellowish brown stripe in the middle of disc. Apices of hooks of ninth abdominal tergite dark brown. Spines of hind tibiae with apices darkish.

Material examined. Holotype ♂, Langping, Chenwanglaoshan, Guangxi, 26 August 2014, coll. Yun Cai.

Measurements (mm). Body 18.8; pronotum 6.3; tegmina 8.7; hind femora 14.1.

Lateral view. 12. Apico-ventral view. 13. Apico-lateral view. 14, 19. Subgenital plate, ventral view. Scale bars: 8–10, 15–18 = 2 mm; 11–14, 19 = 1 mm.

Distribution. China (Guangxi).

Etymology. The new subspecies name refers to the wider brownish stripe of pronotum along the midline. Remarks. The new subspecies is very similar to N. vera vera Gorochov, 2004 , but differs from the latter as following: body smaller, pronotum with yellowish brown stripe along with the edges and 1 wider yellowish brown stripe with the midline of disc. For N. vera vera Gorochov, 2004 , pronotum has narrow yellowish stripe along the anterior margin and small spots at the middle of posterior margin.
