Description of adults . Male (Figs. 6, 8, 9, 10, 12, 32, 33, 34). Large and granulose, antennae missing. Fastigium of vertex above narrow, with angulate apex, in lateral view straight. Crest of pronotum thin, high and strongly curved in lateral view, not serrated in metazona, with shallow transverse sulci and three fenestrae . Tegmina wide, not exceeding the end of abdomen and as long as ¾ of the hind femora, with regularly excurved anterior and nearly pointed apical margins, and with ca. 18-20 stridulatory veins. Hind femur moderately long, relatively stout; upper margin with short, acute teeth, lower margin shallowly serrated. Apical valves of penis stout, narrow, and covered with many small teeth. Posterior margin of epiphallus excurved, pseudolophi placed anteriorly with few teeth. General colouration brownish-grey; on side of pronotum on eye level there is a whitish stripe that continues straight on tegmina (Fig. 12). Second pair of wings vestigial. Female (Figs. 23, 24). Same characters of the male with the following differences. The pronotum crest is moderately high, fenestrae are well visible. Abdominal tergites have a small spine on the posterior margin. Apterous. P. brevis may be distinguished from P. bradyanum because the former has a higher pronotum and mid abdominal segments dentate, while the latter has a lower pronotum and abdominal segments not dentate. Antennae of P. brevis are shorter than those of P. bradyanum . Measurements . See Table 1 .
