Psectrotarsia Dognin, 1907: 240 [type species: Psectrotarsia flava Dognin by monotypy]; Hampson, 1910: 232; Poole, 1989: 842; Matthews, 1991: 20.
Psectrotarsia Hampson, 1908: 5 [Available but without included names until Hampson, 1910: 232] [type species: Psectrotarsia fuscirena Hampson by subsequent designation by Hampson, 1910: 232] [junior synonym and homonym]; Poole, 1989: 843.
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.
