Bioacoustics of Glaphyrosoma (Glaphyrosoma) huasteca

Description. Male. Body larger for genus, shiny and more or less transversally striped ( Figs. 11A , 15A ): head and majority of tergites dark brown but with lower half of frons ( Fig. 11B ), five narrow longitudinal brown to dark brown stripes on dorsum, pronotum with dark brown disc and light brown lateral lobes, each lobe with dark brown stripe along anterior edge and with brown band along posterior edge ( Figs. 11C, D ); rest of body yellowish with light brown to brown most part of outer surface of hind femur, dark brown small marks in region of femur-tibia articulation of hind leg and partly yellowish scape ( Fig. 11A ). Head rounded, and almost 2.5 times as wide as space between antennal cavities; latter space almost three times as wide as scape; ocelli round, almost equal to each other in size, and as wide as pedicel ( Fig. 11B ). Femora without small inner apical spinule. Middle tibia with four ventral spines on each ventral margin. Hind femur with four transversal main pegs rows with few spinules ( Fig. 11E ), hind tibia with ten spines in the dorsal outer and inner margin. First two abdominal tergites with stridulation pegs smaller than the pegs of the others species, very close together; third abdominal tergite with separate peg patch, but less dense than patches on first two tergites ( Fig. 11D ). Posterior edge of the ninth tergite with a medium notch, partially dividing into two lobes, prolonged and covering the last abdominal tergite ( Fig. 11F ). Tenth tergite hooks, robust and conspicuous with the sclerotized apices ( Figs. 11G, H ). Epiproct with rounded posterior edge; each paraproct cylindrical, elongated, curving upwards from the base, with the rounded apex and without spinula, and with a membranous fold, which stretches on the dorsal edge, from the first basal third to near the apex ( Fig. 11I ). Subgenital plate wider than long, conical styles, posteromedian notch shallow and U-shaped ( Fig. 11J ). Female. Similar to the male in shape and coloration ( Figs. 12A, B, C, D , 15B ). Hind femur with four to five transversal main pegs rows with few spinules, on inner side near to base ( Fig. 12E ). First two abdominal tergites with pegs as the male’s, but occupying less area than in the male’s tergites, third abdominal tergite, with few pegs ( Fig. 12D ). Tenth tergite slightly divided dorsally, paraprocts without specialization and ovoid; subgenital plate triangular as wide as long, without the projected apex ( Fig. 12F ). Ovipositor gradually curving upwards from the base, apex slightly sharpened, valves without denticulations or depressions along the margins ( Fig. 12G ). Variation. Apart from size, some specimens, have conspicuous brown stripes covering the dorsum of the body, in contrast to other specimens where the stripes are narrower and the rest of the body is more yellowish.
