Male. Macropterous. Body length 4.9–5.9 mm, forewing length 5.7–6.6 mm (n = 10). Gills absent. Cerci simple and unmodified ( Figs. 95‒96 View FIGURES 95‒98 ). Tenth tergum produced distally as a pair of elongated spiny lobes ( Figs. 95‒96 View FIGURES 95‒98 ). Paraprocts undivided as a sclerotized, triangular lobe. Epiproct compact and complex; dorsal sclerite with three units, basally with paired ca. parallel, elongated lobes ( Fig. 95 View FIGURES 95‒98 ), extending slightly anteriorly as medially-concave narrow ridges ( Fig. 95 View FIGURES 95‒98 ), and somewhat laterally as tapered, lateral arms curving dorsally ( Fig. 95 View FIGURES 95‒98 ); ventral sclerite broadest basally, nearly devoid of hairs or spines, extending dorsally and slightly recurved anteriorly as paired lobes ( Fig. 96 View FIGURES 95‒98 ).
Female. Macropterous. Body length 5.7–7.3 mm, forewing length 6.8–8.4 mm (n = 12). Gills absent. Cerci simple and unmodified. Subgenital plate sclerotized, not produced, and concave medially where the 7 th sternum extends to anterior margin of 8 th sternum ( Figs. 97‒98 View FIGURES 95‒98 ). In relaxed females, a t-shaped sclerotized band is present at the terminus of the 8 th sternum ( Fig. 97 View FIGURES 95‒98 ) but obscured and not seen in most preserved specimens ( Fig. 98 View FIGURES 95‒98 ).
Larva. Described by Harden & Mickel (1952) and Harper & Hynes (1971). Stewart & Stark (2002) provided a full habitus illustration. Additional illustrations were also given by Baumann (1975), Poulton & Stewart (1991) and Harper & Stewart (1996).
Comments. Shipsa rotunda is a monotypic species with a very broad longitudinal distribution across North America, from western Alaska east across Canada to Labrador, New Brunswick, and Nova Scotia, distributed extensively in the USA from the Laurentian Great Lakes region east to New England, but also from Arkansas east to Georgia and north to Maryland ( Grubbs & Baumann 2021; DeWalt et al. 2022). The type locality as listed in Claassen (1923, pg. 290) was spelled incorrectly as Waldeboro (sic).
