Bioacoustics of Paraphlugiolopsis jiangi

Fig. 1 Description. Male. Body small. Fastigium verticis conical, with a median sulcus, apex obtuse. Eyes subglobular. Apical segment of maxillary palpi as long as subapical one, apex slightly inflated. Anterior margin of pronotum nearly straight, posterior margin obtusely rounded; lateral lobe longer than high, humeral sinus absent. Ventral margins of all femora without spines. Procoxae with one small spine; protibiae with 4 pairs of spines on ventral margin; tibial tympana open on both sides, ovoid. Mesotibiae with 3 internal spines and 4 external spines on ventral margin. Genicular lobes of postfemora with apices obtuse; posttibiae with 16–19 internal spines and 16–23 external spines on dorsal margin, 1 pair of dorsal apical spurs and 1 pair of ventral apical spurs. Apices of tegmina reaching the middle area of third abdominal tergite; however, the tegmina of some specimens are concealed beneath pronotum. Stridulatory area of left tegmen nearly trapezoid, large, poorly defined. Stridulatory file elevated on the thickened vein, basal area with one digitate process, 0.37 mm long, with about 27 teeth, which very robust and sparse. Hind wings absent. Tenth abdominal tergite obviously projecting backwards, posterior margin with an obtuse-angular concavity in middle. Cerci longer, moderately curved upwards; one third base slightly stout, the interno-dorsal lobe narrow, nearly rectangle, with obtuse apex ( Fig. 1 E), the interno-ventral lobe narrower, the apical angle nearly triangular ( Fig. 1 G); apical half slightly spine-shaped, faintly depressed, apex obtuse. Basal area of subgenital plate broad, narrowing, basal margin nearly straight; lateral margins bent ventrad; posterior margin nearly straight or slightly projecting in middle. Subapex of subgenital plate with 1 pair of conical styli on ventral margin, apices obtuse. Female. Similar to male with following exceptions: Posterior margin of tegmina for all specimens surpassing posterior margin of pronotum, reaching the middle area of third abdominal tergite. Lateral margin of ninth abdominal tergite obviously protruding backwards; posterior margin of tenth abdominal tergite with 1 faintly concavity in middle. Cerci conical, apices acute. Ovipositor gently curved upwards, base stout, narrowing, dorsal valvulae slightly longer than ventral ones; apices of dorsal valvulae sharply pointed and ones of ventral valvulae hook-shaped. Subgenital plate pentagonal in ventral view, basal margin arched excavate, baso-lateral margin angularly curved dorsad, apical area obtusely triangular, apex obtusely rounded.
