69) Neocononicephora sinuosa Wang sp. n.

Holotype ♂ (both front and middle legs lost): VIETNAM / Blao (Balao) 500m / 14–21.X.1960; C.M. Yoshimoto / Collector

Paratype ♀: same as Holotype

2♂ nymphs: labeled same as Holotype

Description. Head slightly opisthognathous. Farstigium of vertex comparatively broad, with distinct middle furrow. Pronotum disc long and cover stridulatory apparatus, lateral lobe shallow, without humeral sinus. Tegmina and wings shortened, not reach to apex of abdomen. Hind tibiae with 2 pairs of apical spurs.

Male 10 th abdominal tergite slight convex with small slit in middle (Fig. 32c). Cerci thin and long, tapering towards apex, each with a short lobe at base in half length as long lobe, curved inward in right angle. Subgenital plate with distinct longitudinal ridges, bearing pair of short styli (Fig. 32 c–e).

Female subgenital plate short, posterior margin concaved in middle slightly undulated (Fig. 32f). Ovipositor thick and short curved upward, with a small hook on apex of ventral valve (Fig. 32b).

Measurements (mm). Body: ♂ 8.0, ♀ 7.2; Pronotum: ♂ 3.9, ♀ 3.1; Tegmina: ♂ 4.0, ♀ 4.2; Hind femora: ♂ 8.8, ♀ 9.1; Ovipositor: 4.6.

Comparison. This species is similar to Neocononicephora storozhenkoi (Gorochov, 1994) from Vietnam, but differs obviously in detailed shape of male cerci, subgenital plate with small styli. Posterior margin of female subgenital plate in slightly triple undulated form.

Etymology. Name refers to the shape of female subgenital plate with posterior margin in sinuous form.

Note. 2 male nymphs with long, broad and straight cerci, not bent strongly inward, should not be the same species.
