Phlugiolopsis vietnamica sp.nov.

( Figs. 23–26 )

Material. Holotype 3, Vietnam: Fyan, Alt. 900 – 1000m, 1961. VII.11 – VIII.9, leg. N.R.Spencer(Bishop Mus.). Paratype 23, 3ƤƤ, same data as holotype.

Description. Male. Fore tibiae with spines 4, 4(1. 1), mid tibiae with 4 inner and 5 outer spines, hind tibiae with 27 – 29 teeth on inner and outer margin of dorsal surface, and 3 pairs of apical spurs. Tegmina hardly exceeding hind margin of pronotum. 10th abdominal tergite with hind margin shallowly and widely incurved ( Fig. 23 ). Cerci short, thick at basal half，inner surface strongly excavated, the upper lobe with projecting apical corner, lower lobe with truncate apex ( Fig. 25 ); apical half slightly compressed， with obliquely truncate apex ( Fig. 23 ). Subgenital plate with apical margin produced and with short styli.

Female. Subgenital plate transverse, hind margin with 3 lobes ( Fig. 26 ), middle lobe is longer than lateral lobes, broadly rounded, near each lateral lobe with an oblique keel. Ovipositor is shorter than hind femora, apex ovipositor with a small hook on ventral margin.

Coloration. Yellowish brown. Dorsal surface of head with 4 darkish black longitudinal lines, antennae with few and scattered darkish rings, dorsal surface of pronotum with dark brown longitudinal band, kneel lobe of hind femora darkened.

Measurements. (length in mm)

Discussion. This new species differs from other species of this genus in the male cerci with inner upper lobe with projecting inwards, lower lobe with truncate apex, and apical half of cerci compressed, with obliquely truncate apex. Hind margin of female subgenital plate with 3 lobes, middle lobe longer than lateral lobes, broadly rounded, with an oblique keel near lateral lobes.
