Figures 21–23 , 27

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.
