66) Grigoriora cryptocerca Liu sp. n.

Holotype ♂ (both hind legs, right font and middle legs lost): VIETNAM: DaiLanh/N. of Nha Trang/ 30.XI.–5.XII.’60; C.M. Yoshimoto / Collector

Paratype ♀ (both middle legs lost): VIETNAM: / Blao (Balao) 500m / 14–21.X.1960; C.M. Yoshimoto / Collec- tor

5 nymphs: labeled same as Paratype. (These nymphs are too young to be identified, which should not be the same species as Types.)

3 nymphs: VIETNAM: Mt. Lang / Bian, 1500–2000 m./ 19. V .–8. VI .1961;N. R. Spencer / Collector / BISHOP

Description. Body comparatively small. Head opisthognathous, fastigium of vertex with round apex, middle furrow distinct. Pronotum with shallow lateral plate, humeral sinus indistinct ( Fig. 30a ). Tegmina and wings median long, not reach to the apex of hind femur. Hind tibia with 3 pairs of apical spurs. Male 10 th tergite without posteriomedian notch, broad and elongated, nearly cover the whole cerci; epiproct small oval lobe, cerci short and simple lobe, base thick and tapering toward apex ( Fig. 30c, e ). Subgenital plate short and narrow, with nearly even posterior margin, bearing tiny styli ( Fig. 30d ).

Female subgenital plate short, posterior margin truncate with a small median slit and 2 lateral ridges ( Fig. 30f ). Ovipositor straight with smooth apex ( Fig. 30b ).

Comparison. This species from Vietnam is quite different from all other species of the genus by male 10 th tergite elongated and small epiproct. It could be a separate genus when more material is available to support.

Measurements (mm). Body: ♂ 12.2, ♀ 10.8; Pronotum: ♂ 5.1, ♀ 4.2; Tegmina: ♂ 10.5, ♀ 7.6; Hind femora: ♀ 10.3; Ovipositor: 9.5.

Etymology. Name refers to the male 10 th tergite almost cover the comparatively short cerci.

Note. 8 male nymphs bearing same labels as paratype, with long and broad cerci, which seem not be the same species as Types.
