Parapsyche cardis Ross 1938: 119, pl. 12 fig. 4, holotype 3 deposited in INHS. Ross 1944: 78 –83, figs. 289, 298, 300, 306, 316 (larva, pupa); Flint 1961: 10 –11, figs. 22–26, 30 (larva, pupa); Schmid 1968: 73, figs. 114–117 (3).
Diagnosis. Hind wing crossveins sc-r and r-rs are not coincident in the insertion on R, their insertions being separated by at least the length of crossvein r-rs. Paired, sclerotized, anteroventrad-directed projections are visible inside segment IX.
Description. Wings (Fig. 28): fwl = 10.6–14.4 mm; = 12.1; σ = 1.18 (N = 32). Wings sub-hyaline, infuscate with light mottling, shape typical for subfamily. Female genitalia (Figs. 21–23): Segment IX (IX) in lateral view (Fig. 21) relatively short in its longitudinal dimension throughout its height; anterior margin sinuous; dorsum about 1/5th as long as height of segment IX, produced as prominent angle dorsally; in caudal and internal views (Figs. 22, 23), dorsum with vertex convex; sides of segment IX with pronounced lateral bulge in basal 1/3rd; with paired, sigmoid, sclerotized rods inserting inside venter of segment IX. Prominent articulation ventrolaterally between segment IX and segment X (X), with segments IX and X strongly sclerotized. Pair of circular setal patches (sp) mediolaterally on posterior horizontal face of dorsum of segment IX, setae in 3 rows (Fig. 27).
Distribution. Narrowly distributed in the eastern United States, apparently restricted to the southern Appalachian Mountains of Tennessee, North Carolina, South Carolina, and Virginia. Often syntopic with A. irrorata and P. apicalis in cold-water mountain streams and rivers.
