Bioacoustics of Glomeremus tikasignatus

Description. In addition to generic characters. Body length: size medium to large for the genus. Head ( Fig. 3 ): as broad or slightly broader than the thorax; fastigium frontis wider than scapus; median and lateral ocelli clearly distinct (less obvious on specimens dried from alcohol), median ocellus circular, less wide than scapus. Thorax. Pronotum: maximal width (including lateral lobes) as wide as or slightly wider than long; anterior margin convex (in dorsal view), arched; posterior margin strait (in dorsal view), almost horizontal; anterior sulcus deep on lateral lobes and well distinct on discus; posterior sulcus shallower and less distinct on discus; both sulci converging on lateral lobes; prozona elevated. 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 (at least as long as T width). Hind legs: femora 3.4–3.7 times as long as wide ( Fig. 6 ); FIII with 5–7 ventral anterior spines; FIII with 6–11 ventral posterior spines; TIII with 5–7 dorsal anterior spines; with 6–8 dorsal posterior spines. Abdomen. Stridulatory files present.

Male: terminalia ( Fig. 9, 12, 15 ). 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 shallow emargination separating two small bulges (ventral/ posterior view; Fig. 15 ). TX sclerites (see Hugel, 2009 ) forming an upwards directed lamellar process ( Fig. 12, 15 ). Cerci not particularly elongated ( Fig. 15 ). SGP distal end with an indistinct emargination ( Fig. 9 ); styli exceeding distinctly the SGP distal end, not thickened ( Fig. 9 ). Female : sternite before SGP (VII) not modified; SGP ( Figs. 18, 21 ) with strait lateral margins, posterior margin pointing ventrally (side view, Fig. 18 ), the posterior end corresponds to the SGP dorsal surface, with a shallow “W” shape (ventral view, Fig. 21 ). Ovipositor regularly arched, pointing distally, as long as FIII, dorsal valves without ventrally directed protrusion. Colour: general coloration brown; head, legs pronotum without black pattern (knees sometimes darkened); anterior part of abdominal tergites darkened; median and lateral ocelli white.
