Bioacoustics of Glomeremus paraorchidophilus

Description. In addition to generic characters. Body length: size small for the genus. Head: slightly broader than the thorax; fastigium frontis wider than scapus; median and lateral ocelli weakly distinct. Thorax. Pronotum: maximal width (including lateral lobes) slightly wider than long; anterior margin weakly convex (in dorsal view), arched; posterior margin strait (in dorsal view), almost horizontal; sulci not distinct on the discus, converging on lateral lobes. Wings. FW well distinct, half as long as Pro. Legs. TI and TII with usual spurs formula (4 pairs of subapical + 1 pair of apical spurs ventrally, and one single apical spur on TII posterior dorsal angle); subapical spurs of usual length (roughly at least as long as T width). Hind legs: femora 2.5–3.0 times as long as wide ( Fig. 5 ); FIII with 2–8 (usually 6) ventral anterior spines; FIII with 3–7 ventral posterior spines; TIII with 6–8 dorsal anterior spines; with 6–7 dorsal posterior spines. Abdomen. Stridulatory files present.

Male: terminalia ( Fig. 8, 11, 14 ). Tergite VIII slightly extended posteriorly (compared to preceding tergites); posterior margin forming a 45° angle (in side view). Tergite IX vertically oriented (side view); distal end of tergite pointing ventrally (side view) with a distinct emargination separating two lobes (ventral/ posterior view; Fig. 14 ). Tergite X sclerites (see Hugel, 2009 ) forming an upwards/sideward-directed lamellar process ( Fig. 11, 14 ). Cerci shortened ( Fig. 14 ). SGP distal end with a distinct process between the styli; lateral margins of the process weakly converging; process with a distinct posterior notch ( Fig. 8 ); styli hardly exceeding the SGP distal process; styli not thickened ( Fig. 8 ). Female : sternite before SGP (VII) not modified; SGP ( Figs. 17, 20 ) with rounded lateral margins; with anterior bulge (side view, Fig. 17 ) posterior margin with a shallow emargination ( Fig. 20 ); with two distal lateral sclerifications. Ovipositor regularly arched, regularly narrowing towards the apex; pointing distally, 0.7 – 0.8 times as long as FIII, dorsal valves with a distinct ventrally directed protrusion near the basis. Colour: general coloration brown yellowish; occiput with a black pattern forming a triangle pointing on the fastigium frontis (as in G. orchidophilus n. sp. ; Fig. 2 ); pronotum with a black pattern on the anterior margin, forming a triangle pointing backwards, sometimes with a black sagittal line and black on the posterior margin; legs without black pattern; knees sometimes darkened; anterior part of abdominal tergites darkened.
