Bioacoustics of Ellipes ignis

Measurements (mm) . Body (head to end of abdomen): ♂ , 3.5–3.7; ♀ , 3.8–4.5; length of pronotum: ♂ , 0.8; ♀ , 0.7–1.0; length of forewing: ♂ , 0.8; ♀ , 0.7–0.9; length of hind femur: ♂ , 1.8–2.0; ♀ , 1.9–2.2. Description . Male ( holotype ) . ( Fig. 2 ). Coloration in life ( Fig. 1 ): Head burgundy, with short pale spur derived from base and another short pale streak just below compound eye; antennae light brown; eyes black. Pronotum brick red with anterior edge burgundy; lower posterior corner of lateral lobe rusty orange. Forelegs tan, darkening to brown on tibiae and tarsi; middle legs creamy, with dark markings on femora and tibiae, and elliptical yellow mass in tibiae; hind femora creamy, with two irregular brown transverse bands; apical crescents of hind femora brick red; hind tibiae brick red but fading to cream apically. Tegmina dark brown, anal area white; abdomen dark brown, with apical borders of tergites tan; basal segment of cercus dark brown, apical segment dark cream; paraproct processes yellow. Note that coloration fades considerably in ethanol-preserved specimens, especially compared with other Florida Ellipes species. Antennae 10-segmented; head and pronotum with sparse covering of short pale setae. Forewings about as long as pronotum; hind wings absent. Male stridulatory file ( Fig. 3C ) 0.4 mm in length, with about 44 teeth. Swimming plates of hind tibia absent. Male epiproct ( Fig. 3A ) about as wide as long; shallowly indented basally, convex apically, with long apical bristle about ¾ its length. Paraproct hooks strongly sclerotized, rounded apically and greatly widened at middle. Male subgenital plate ( Fig. 2C ) unspecialized, broadly rounded. Female subgenital plate ( Fig. 2D ) tapered apically, with rounded apex.
