Bioacoustics of Ruidocollaris latilobalis

Description. Male ( holotype ). Size median for typical phaneropterines. Pronotal disc with distinct “U”- shaped middle transverse groove lying slightly before middle, and third transverse groove lying slightly behind middle; anterior margin slightly concave, posterior margin widely round. Anterior femur armed with 6 spines on ventro-anterior margin; median femur armed with 5–8 spines on ventro-anterior margin; posterior femur with 7 anterior spines on ventral margins. Median tibiae with 5 posterior spines on dorsal margins; posterior tibiae with 13 anterior and 15 posterior dorsal spines. Tegmen: Wings developed well. Hind wing longer than tegmen. Tegmen extending beyond apex of hind femur. Radial vein of tegmen with two other oblique branches reaching posterior margin after radial sector vein ( Fig. 94 ). Male stridulatory vein long, with stridulatory file composed of about 101 densely arranged teeth ( Fig. 29 ). Right stridulatory area with distinct irregular triangular mirror ( Fig. 18 ). Tenth abdominal tergum with apical margin truncated, epiproct tongue-shaped. Cerci conical, slightly incurved, apex with two obtuse teeth ( Fig. 56 ). Subgenital plate much longer than wide, apical margin with a wide triangular notch at middle; styli robust, as long as quarter subgenital plate ( Fig. 65 ). Female tenth abdominal tergum not produced, with dorso-medial groove; posterior margin obtusely emarginated. Epiproct wider than long, triangular. Cerci conical, slightly curved ( Fig. 74 ). Subgenital plate triangular, wider than long; lateral margins slightly concave; apex obtuse (Fig. 82). Ovipositor distinguished, tapering towards apex, less longer than pronotum, twice much longer than wide, with both margins serrated; apex pointed. Coloration ( Fig. 94 ). Green. Tegmen green, with some small dark spots clustered into small globes in Radial-Medial area, and numerous dark dots in areas adjoining to posterior margin. Measurements (mm). Length of body: male 31.5, female 29.5; of pronotum: male 7.6, female 7.8; height of paranota: male 5.1; length of paranota: male 4.9; of tegmen: male 42.5, female 43.2; largest width of tegmen: male 12.0, female 13.5; length of hind wing: male 48.5, female 47.8; of posterior femur: male 21.0, female 23.5; of apical style of male: 1.1; length of ovipositor 7.4; largest width of ovipositor 3.1.
