Bioacoustics of Kosciuscola restrictus

Redescription. Coloration: Male head bright green, often with yellow markings on gena below eyes (especially when alive). Eye brown. Antennae tan. Male pronotum uniformly green or green/brown dorsally, lateral carina cream color, lateral portion of prozona dorsally black and ventrally with green patches ( Figs. 1C , 5A, 5B, 5D, and 5E ). Male tegmina creamy white dorsally, black laterally. Legs brownish yellow, with dorsal portion of hind femur green, brownish tan knee ( Figs. 1C, 1D , 5B ). Male abdomen more or less uniformly green with some dark markings laterally. Female head more or less uniformly green with brown/black marking near dorsal ocelli. Female pronotum green/brown dorsally ( Fig. 1D ), lateral carina cream color, lateral portion of prozona dorsally black and ventrally with green patches. Female tegmina creamy white dorsally, upper half of the lateral part black, lower half brown. Female abdomen bright green to tan brown with a broad dorsal stripe running anterior-posteriorly, laterally dark brown ( Fig. 5J ). Head: Median carinula of fastigium faintly present and extending to vertex ( Fig. 5E ). Fastigial furrow faintly present and boundary disappearing posteriorly ( Fig. 5E ). Anterior apex of fastigium from dorsal view narrowing apically. Frontal ridge raised past frontal suture, nearing clypeus. Median portion of frontal ridge slightly depressed below ocellus ( Fig. 5C ). Preocular ridge distinct and reaching clypeus. Subocular ridge deeply grooved. Frontal integument smooth with faint punctures ( Fig. 5C ). Gena in male normal and never bulging ( Fig. 5D ). Thorax: Pronotum ( Fig. 5D, 5E ): Shape of anterior margin of pronotum slightly concave toward pronotum. Anterior margin of prozona somewhat constricted to form a distinct ridge along the margin. Lateral carina constricted as distinct ridges. Dorsal profile of lateral carina only slightly widening toward posterior end without much constriction near anterior sulcus of prozona. Lateral lobes from dorsal angle not bulging out. Texture of dorsal surface slightly matted. Anterior sulcus of prozona faint. Anterior sulcus of prozona not touching median carina. Anterior sulcus extending to lateral lobe ending before touching lateral carina. Posterior sulcus of prozona not touching median carina. Posterior sulcus extending down to lateral lobe. Posterior margin of metazona slightly incurved. Texture of dorsal surface of metazona lightly rugose. Texture of lateral lobe of prozona smooth and shiny. Prosternal process ( Fig. 5H ): Triangular and narrowing toward apex to form pointed end. Tegmina ( Fig. 5D ): Dorsal profile formed by the area above subcosta wide. Lateral profile dorso-ventrally wide. Posterior apex from lateral view dorsally projecting more than ventrally. Abdomen: Dorsal surface of first and second abdominal segment lateral ridges absent. Male cerci ( Fig. 5F, 5G ): Lateral view of male cercus simple and triangular, tapering toward apex. Length of male cercus as long as epiproct. Dorsal view of male cercus simple, conical. Male furcula ( Fig. 5G ): Dorsal view of furcula round and distinct. Space between furcula lobes as wide as a single lobe. Male epiproct ( Fig. 5G ): Ridge along lateral margin of epiproct thin. Lateral plates of epiproct slightly concave. Posterior apex of epiproct broadly projecting forward. Male subgenital plate ( Fig. 5G ): Apex of male subgenital plate slightly quadrate and narrowing towards apex. Female subgenital plate: Postvaginal sclerite absent. Male genitalia: Epiphallus ( Fig. 6G, 6H ): Shape of ancorae short and broadly tapering toward apex inwardly. Anterior projection not bulbous. Lophi in dorsal profile distinctly bilobed with lateral lobe projecting more than mesal lobe. Inner side of lateral plates moderately projecting upward. Shape of lateral lobe of lophi broadly projecting as round projection, not as quadrate as in tristis . Shape of mesal lobe of lophi somewhat round quadrate. Space between mesal and lateral lobe of lophi narrow. Width of a single lophus distinctly narrower than half plate. Base of lophi distinctly angular to bridge. Height of lateral plate inner margin much narrower than outer margin. Shape of lateroventral plate not expanding. Outer side of lateroventral plate straight. Ectophallic sclerite ( Fig. 6F ): Two halves simply meeting in the middle. Membrane connecting epiphallus and cingulum membranous. Cinglum: Shape of rami not projecting. Dorsal aedeagal sclerite of endophallus elongate and tapering toward apex, with inner side straight and outside curved. Ventral aedeagal sclerite of endophallus simple rod-shape and shorter than dorsal aedeagal sclerite. Apodemes of cingulum narrow and elongate all the way to the end of endophallus. Female genitalia: Dorsal sclerite of the bursa absent. Spermatheca apical arm much shorter than apical diverculum. Measurements (in mm). Body length to end of hind femur: 15.79 1.28 (male, n = 10), 23.69 2.76 (female, n = 10); hind femur length: 10.47 0.54 (male, n = 10), 14.39 0.89 (female, n = 10). Type.
