Atopsyche (Atopsaura) zernyi Flint ; Blahnik et al. 2004, 4 (distribution); Paprocki et al. 2004, 7 (checklist); Dumas et al. 2010, 7 (distribution); Calor 2011, 320 (checklist).

Diagnosis. This species belongs to the Atopsyche (Atopsaura) longipennis Group and most closely resembles A. blahniki and A. hamata in that the apicomesal process of the first article of each inferior appendage is slightly shorter than the second article in these species. It can be recognized by the apical portion of the phallotheca possessing two spines on each “beak”, one apical and the other lateral ( Flint 1974).

Description. Overall body color brown to yellowish. Frons and vertex of head with brown and whitish setae. Antennal scapes yellowish with elongate dark brown and whitish setae, pedicels yellow, basal flagellomeres light brown and apical flagellomeres brown. First and second articles of maxillary palps with long, brown setae. Legs yellowish to light brown. Forewings brown and irregularly marked with various shades of brown ( Flint 1974), covered by small brown and yellow setae, erect dark brown setae of veins, apices with fringes of brown and whitish setae. Sternum V with remarkable anterolateral processes about half as long as sternum ( Fig. 2 A; Flint 1974).

Remarks. Some specimens have 3 spines on each beak of the phallotheca ( Fig. 2 B), differing from the original description, which cited only 2 spines. The 3rd spine frequently is positioned between the 2 spines described for A. zernyi by Flint (1974) and it has variable length, although it is frequently shorter than the other 2 spines. Parapods also show some variability ( Figs. 2 C–H).
