Bioacoustics of Miogryllus muranyi

Description. Holotype male: color pattern on dorsal surface of body as in Fig. 1 . Head ( Figs. 3, 4 , 13 to 18) with a peculiar shape, characterized by the following: eyes black with a conspicuous band of unpigmented ommatidia on supero-frontal angle; area behind each eye with a brown macula on a whitish background; lateral ocelli large, the median quite smaller; dorsum of head medium to dark brown; antennal scape depressed, dark brown at base but gradually becoming light brown towards the apex, flagellum median brown; inter-antennal space/scape breadth= 3.15; frons wide, flat and decidedly vertical, forming a 90 degree angle with dorsum of head along sagital line, almost white inferiorly but gradually becoming dark brown near the median ocellus; epistomal suture shaped as a broad inverted “V”; clypeus very large, whitish, its superior portion much inflated, inferior portion bearing a pair of small digitiform projections which are separated from the superior portion of the structure by a broad, deep depression; labrum forming a case that conceals the entire inferior portion of the mandibles; palpi whitish ( Fig. 19 ); gena almost white; base of mandibles nearly white but becoming very dark brown towards the apex. Pronotum much broader than long ( Figs. 1 , 17 ), the lateral lobes with a very broad white area surrounded by dark brown margins, disk marbled of light and medium brown ( Fig. 1 ); right fore wing very light brown, harp area and lateral field poorly pigmented, venation as in Figs. 5, 6; stridulatory vein with 123 teeth; hind wings vestigial, unpigmented; tibia I with a large, elongate auditory tympanum on outer face only, three apical spurs present; tibia II with four apical spurs; tibia III with five alternating dorsal spurs on both sides (Figs. 7 A, B); dorsum of hind basitarsus with 7 teeth on outer row and 6 on inner; mesosternum subquadrate, metasternum nearly round along fore and lateral margins ( Fig. 20 ). Supra-anal plate trapezoid, as long as its breadth at base ( Fig. 21 ); subgenital plate long ( Fig. 8 ). Phallic complex ( Figs. 9 A, B, C) very similar to those of other species of Miogryllus , characterized by the following: main body of pseudepiphallus with a deep posterior U-shaped invagination coupled to a pair of acute projections, rami not fused proximad, pseudepiphallic apodemes present, pseudepiphallic parameres small; ectophallic apodeme and arc somewhat W-shaped as seen from dorsum, ectophallic fold acute, endophallic cavity large. Measurements (mm ) . Head width 5.54; Inter-ocular distance 4.3; Pronotum length 2.85; Pronotum width 5.05; Fore wing length: 7.74; Femur III length 9.89; Tibia III length 6.67. F emale: similar to male in overall size and many details, including: color patterns of all head areas and structures; lateral lobes of pronotum also bearing a broad white area surrounded by dark brown margins; limbs colored as in the male; inner row of teeth on hind basitarsus also with 6 elements (outer row with 8 on female and 7 on male); meso and metasternum rather similar to those of male ( Fig. 26 ). Differences from male: color pattern slightly different on dorsal surface, especially that of pronotum disk ( Figs. 1 and 2 ). Head normal-shaped, much different from that of male ( Figs. 23 , 24, 25 ); inter-antennal space/scape breadth= 3.04; lateral field of fore wings with six parallel veins below angulation; supra-anal plate as in Fig. 27 ; hind margin of subgenital plate slightly concave ( Figs. 11 , 28 ); tip of ovipositor as in Figs. 12 A, B, C. Measurement (mm). Head width 5.05; Inter-ocular distance 3.55; Pronotum length 3.33; Pronotum width 4.95; Fore wing length: 3.12; Femur III length 10.43; Tibia III length 7.31; Ovipositor length 11.56.
