Male. Macropterous. Body length 4.2–5.4 mm, forewing length 5.5–6.4 mm (n = 17). Gills absent. Cerci enlarged but compact, sclerotized, and curving medially to an apical point ( Figs. 37–38 View FIGURES 37‒42 ). Paraprocts divided into a membranous outer lobe and a sclerotized, sickle-shaped inner lobe; inner lobes short, tapering along a smooth curve and divergent apically ( Fig. 40 View FIGURES 37‒42 ; Young et al. 1989, their fig. 25). Epiproct elongate and complex; dorsal sclerite smooth with a middorsal groove and ventrally with small posteriorly-projected lateral arms ( Fig. 40 View FIGURES 37‒42 ); ventral sclerite with basal, mid-dorsal groove and apically laterally expanded and bell-shaped ( Figs. 37–39 View FIGURES 37‒42 ).
Female. Macropterous. Body length 4.3–6.6 mm, forewing length 6.3–7.5 mm (n = 17). Gills absent. Cerci enlarged but unmodified ( Fig. 41 View FIGURES 37‒42 ). The 8 th sternum is enlarged as a subgenital plate and extended over the anterior margin of the 9 th sternum. The plate is broad basally, narrowing slightly such that the posterior half is approximately 3/4 of the sternum width; posterolateral corners of the plate are extended as subtriangular processes and the medial region is either straight or with a small gently-rounded medial projection ( Figs. 41–42 View FIGURES 37‒42 ). The 7 th sternum is unmodified ( Figs. 41–42 View FIGURES 37‒42 ).
Larva. Stewart & Stark (2002) provided a full habitus illustration. Partial illustrations were also given by Baumann (1975), Harper & Stewart (1996), and Stark (2017)
Comments. Similar to the other three eastern Ostrocerca species, O. truncata exhibits a widespread Appalachian distribution ( DeWalt et al. 2022) but extends further southward through Tennessee to northeastern Alabama ( Young et al. 1989) and westward across southern Ohio ( DeWalt et al. 2016) to southern Indiana ( Grubbs 2004), southern Illinois, and central Kentucky ( Grubbs et al. 2005).
