Materials.

Holotype♂, Vietnam, 40km S of Dilanh (Djiring), Alt. 543m, 1960.IV.26, coll. L.W. Quate (BPBM). Deposited in SEM temporarily.

Description.

Male. Fastigium of vertex short, without dorsal groove, face slightly oblique (Fig. 42), compound eyes oval and protruded forwards and outwards, last segment of maxillary palpi slightly longer than preceding. The superior edge and inferior edge of pronotum paralleled and almost straight, paranota lower, front margin little sinuate, hind margin straight without humeral sinus and obliquely truncated; auditory foramina of thorax small and entirely exposed. Tegmina almost equal to pronotum, apex rounded; hind wings degenerate. Fore tibiae armed ventral spines of type 4, 4 (1, 1), lower lobe of the hind knee bearing a spine, hind tibiae with 28-31 dorsal teeth each margin above and 2 pairs of apical spurs. Hind margin of 10th abdominal tergite little sinuate (Fig. 43), lower part becoming a pair of elongate branches (Figs 44-45); cerci robust, generally conical and apex blunt, but each with 2 long inner processes: prior one downward, posterior one upward and little branched at apex. Subgenital fig damaged.

Female unknown.

Coloration.

Body yellowish (may be greenish alive), eyes blackish brown, antennae with inconspicuous darkish rings.

Measurement.

(length in mm) Body, ♂12.0; pronotum, ♂3.8; tegmina, ♂4.0; hind femora, ♂12.0.

Discussion.

This new species is similar to Pseudothaumaspis gialaiensis Gorochov, 1998, but differs mainly in the appearance of the male cerci. The single specimen of this species is in bad condition, especially the abdomen. Fortunately, the unique ventral arms of the 10th abdominal segment and the cerci are intact.

Etymology.

The specific epithet refers to the character of male cerci which bearing 2 spinous processes, compose by prefix 'bi-' which means double and 'spinosus' which means spiny.

Distribution.

Vietnam.
