Key to the genera of the tribe Xyphosiini

1 Vein R4+5 setulose to crossvein dm-cu..................................................................... 2

- Vein R4+5 bare or with 1–5 setulae at node dorsally........................................................... 4

2 Posterior orbital seta inclinate. Thoracic calypter 1.5–2 times as long as alar calypter, distinctly protruding beyond it. Wing brown or yellowish-brown, with reticulate pattern of large, partly fused hyaline spots. Crossvein dm-cu surrounded by wide brown area without yellow or hyaline spots in it. Larvae in flower heads of Carduus , Centaurea , Cirsium spp. ( Cardueae ). Palaearctic Region........................................................... Xyphosia Robineau-Desvoidy. ..3

- Posterior orbital seta reclinate. Thoracic calypter short, barely protruding beyond alar calypter. Wing with massively fused yellow spots, irregular dark marks between them, and border of apical half distinctly darkened. Surrounding crossvein dm-cu yellow with brown spots. Larvae in flower heads of Bidens spp. (Heliantheae). Nearctic Region.............. Icterica Loew

3 Femora thickened; mid and hind femora long and densely setose ventrally. Larvae in flower heads of Centaurea spp....................................................................................... Xyphosia (Trichoxyphosia)

- Femora not thickened; mid and hind femora long and at most short setulose ventrally. Larvae in flower heads of Carduus and Cirsium spp.......................................................................... Xyphosia (Xyphosia)

4 Vein R4+5 bare dorsally and ventrally. Posterior orbital seta inclinate. Nearctic Region.......... Neaspilota Osten Sacken 5

- Vein R4+5 with 4–5 setulae at node dorsally. Posterior orbital seta variable. Palaearctic Region........................ 7

5 Wing predominantly or entirely hyaline, sometimes with series of pale brown spots or 2–3 bands..................... 6

- Wing brown with reticulate pattern of hyaline spots as in Ictericodes . Larvae in Coreopsis (Heliantheae) .................................................................................................. Neaspilota (Footerellia)

6 Frontofacial angle rounded. Male fore tarsus usually modified, asymmetrical. Larvae in flower heads of Ve r no ni a (Vernonieae)............................................................................. Neaspilota (Neaspilota)

- Frontofacial angle projecting. Male fore tarsus usually unmodified, symmetrical. Larvae in flower heads of various hosts, but not Ve r no ni a ....................................................................... Neaspilota (Neorellia)

7 Wing brown with reticulated pattern of hyaline spots. Posterior orbital seta reclinate................... Ictericodes Hering

- Wing hyaline with banded yellow pattern ( Figs. 1, 4 ). Posterior orbital seta inclinate.................. Va ler a new genus
