Bioacoustics of Eubliastes viridicorpus

Description. – Head: around 1.4x longer than wide, with eyes that do not extend far beyond the gena laterally. Postclypeus (dorsal clypeus) black. Dorsal frons and gena black. Frons with distinct U-shaped marking ventrally and two dots centrally ( Fig. 1A and B ). Thorax: Mostly vivid green in colour, with beige/amber moving ventrally, and black markings on dorsal margins of all leg coxae ( Fig. 1C ). The acoustic spiracle in the prothorax is small as expected for the subfamily, and kidney bean shaped ( Fig. 1C ). Legs: Forelegs and midlegs dorsally unarmed, ventrally with four pairs of spines on tibiae. Foretibae bearing large tympanal organ with wide pinnae, and eight pairs of ventral spines, with first pair distal of the tympanal organ. All legs reddish-brown with vivid green towards coxae. Midfemur and hindfemur with light beige/amber band towards distal end before joint. Beige/amber band contains dark spots, 5–7 in sequence on all femurs. Mid- and hindfemur spines light beige/amber at base, black at tip. Hindfemur armed with ten ventral spines. Hindtibiae armed with 12 pairs of spines ventrally and 17 dorsally. Genicular lobes rounded and without dark pigmentation. Wings: Large, extending distally beyond terminalia but not beyond hindlegs ( Fig. 1D ). Striking yellow venation pattern. Within-cell tegminal colour black rather than the vivid light green of E. chlorodictyon ( Montealegre-Z and Morris, 1999 ), or the ochraceous tawny brown of other members of the genus ( Fig. 1C ). Male stridulatory field large and circular, with strongly raised CuPb vein and stridulatory file. Stridulatory file with 262 teeth. Wings shorter than E. pollonerae ( Beier, 1960 ) . Abdomen: Follows colour pattern of thorax, with mostly vivid green colour dorsally, with beige/amber moving ventrally. Lacks black markings as seen on thorax. Terminalia: Male: subgenital plate elongate without strong emargination, centrally depressed ( Fig. 1E (i)), with two long styli. 10th tergite truncate with central emargination ( Fig. 1E (ii). Cerci large, beige/white, and robust, with curved spine on inner edge ( Fig. 1E (iii)). Styli at unique obtuse angle with subgenital plate ( Fig. 1E (iii)). Female: subgenital plate isosceles triangular with rounded subbasal lobes and pronounced soft V-shaped emargination ( Fig. 1F (i)). Cerci cream white, pointed with spine ( Fig. 1F (ii)). Ovipositor broad, smooth with distal serrations dorsally, and four lateral notches; reddish-brown and basally amber/ beige ( Fig. 1F (iii)). Coloration. – In live animal colours unusually bright for genus ( Fig. 1C ). Dorsal pronotum and head a cordovan brown colour, with a lateral gradient typical of the genus. Ventral edges of pronotum, head, and most of body a vibrant green. Frons a deeper vibrant green. Wing venation electric yellow. Within-cell tegminal colour black. Large male cerci and distal patch on hind femur matching in light beige. Bases of spines on hind femur also beige. Markings on face and legs black.
