Erythroecia Hampson, 1910: 57 [type species: Heliothis suavis H. Edwards by subsequent designation by Hampson, 1910: 57]; Dyar, 1912: 65; Barnes and McDunnough, 1917: 69; Forbes, 1954: 255; McDunnough, 1938: 98; Hardwick, 1970: 25; Franclemont and Todd, 1983: 158; Poole, 1989: 380; Rings et al., 1992: 139; Poole and Gentili, 1996: 739; Hardwick, 1996: 40. New synonym.

Redescription. Head ( Figs. 1–5 ): Frons bulbous with distinct transverse ridges or cylindrically produced, ventral lip slightly produced; eyes fully developed; labial palp moderately porrect, apex at approximately half eye height; antenna filiform, scaled dorsally, unscaled ventrally; vertex with flat scales overlain with hairlike scales (flat scales best seen on more worn specimens). Thorax: Patagium, tegulae, and thorax with flat scales overlain with hairlike scales; foretibia unarmed; underside clothed with long, hairlike scales. Abdomen: Dorsally with base of narrow scales overlain with fine hairlike scales, ventrally with base of wide flat scales overlain with long hairlike scales; second tergite with two pairs of lateral sclerotized bars, scent pockets and hair pencils absent. Male genitalia ( Figs. 16–25 ) with uncus elongate, approximately 0.37X length of valve, apex pointed; valve flat and straplike, length 5.0–5.5X width; corona present; ampulla arising from dorsal margin of sacculus, narrow, curved, elongate, approximately 0.20X length of valve; sacculus well developed; juxta rectangular with lateral margins round, dorsal and ventral margins excavated; saccus V-shaped; aedoeagus approximately 0.75X length of valve, apex narrow, vesica oriented on left side and opening of ductus ejaculatorius dorsad, a series of appressed, scobinated bars from middle to apex on left side of aedoeagus; vesica Yshaped, with a short basal diverticulum bearing a short apical spinelike cornutus, lateral elongate diverticulum bearing a long apical spine-like cornutus, second elongate diverticulum (bearing orifice of ductus ejaculatorius) lacks a cornutus. Female genitalia ( Figs. 26–36 ) with papilla analis soft, lightly sclerotized with short, elongate setae, apex rounded; ovipositor not telescopic; anterior apophysis narrow, not extending below ninth segment; posterior apophysis narrow, approximately same length as anterior apophysis; ninth segment smooth with moderately elongate setae around distal margin; ostium bursae lightly sclerotized, covered with spiculi; distal one third to two fifths of ductus bursae membranous, proximal portion ribbed, sclerotized and continuing into apical portion of corpus bursae; corpus bursae elongate; appendix bursae extends dorsad to juncture of ductus bursae and corpus bursae, ribbed sclerotized area of ductus bursae curves into base of appendix bursae; signa absent.

Discussion. The monophyly of Psectrotarsia is based on two putative synapomorphies: elongate ampulla and multi-diverticulate vesica bearing cornuti in the male genitalia. The genus Erythroecia was synonymized based on these synapomorphies.

Five species currently are placed in Psectrotarsia , two from North America and one each from Mexico, Guatemala, and Peru.
