Holotype male (Cornell University Insect Collection), Waldoboro, (Lincoln Co.), Maine, USA Nemoura rotunda: Needham & Claassen, 1925:219 Nemoura rotunda: Claassen, 1940:62 Nemoura rotunda: Ricker, 1944:177 Nemoura rotunda: Harden & Mickel, 1952:17 Nemoura (Shipsa) rotunda: Ricker, 1952 Shipsa rotunda: Illies, 1966 Nemoura (Shipsa) rotunda: Harper & Hynes, 1971:1139 Shipsa rotunda: Zwick, 1973 Nemoura (Shipsa) rotunda: Hitchcock, 1974:104 Shipsa rotunda: Baumann, 1975:54, 63 (in part), 66 (in part) Shipsa rotunda: Dosdall & Lehmkuhl, 1979:38 Shipsa rotunda: Stewart & Stark, 1988:185 Shipsa rotunda: Poulton & Stewart, 1991:30 Shipsa rotunda: Stewart & Stark, 2002:211 Shipsa rotunda: Stewart & Oswood, 2006:81 Shipsa rotunda: Grubbs & Baumann, 2021:51 Distribution.

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). Tenth tergum produced distally as a pair of elongated spiny lobes (Figs. 95‒96). 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), extending slightly anteriorly as medially-concave narrow ridges (Fig. 95), and somewhat laterally as tapered, lateral arms curving dorsally (Fig. 95); ventral sclerite broadest basally, nearly devoid of hairs or spines, extending dorsally and slightly recurved anteriorly as paired lobes (Fig. 96). 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). In relaxed females, a t-shaped sclerotized band is present at the terminus of the 8 th sternum (Fig. 97) but obscured and not seen in most preserved specimens (Fig. 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).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
