Box 37012, NMNH, MRC-168, Washington, District of Columbia 20013-7012, USA AND CHAHLES E. HAHP 8834 West Quarto Avenue, Littleton, Colorado 80128, USA ABSTRACT. Schinia regina, new species, is described and illustrated. Diagnostic eharacters and host plant distributions are compared with Schinia regia (Strecker) and Schinia niveicosta (Smith). The larval host plant of Schinia regina, Palafoxia sphacelata (Nutl. ex Torr.) Cory (Asteraceae), is reported for the first time. Genitalic images and descriptions of both sexes are presented for all species. Additional key words: taxonomy, biology, host plants, Asteraceae. We are currently working on the Moths of North were ivory with a magenta median stripe and in S. re America fascicle of the Noctuidae subfamily Helio gia the larvae were mauve with a gray median stripe thinae. Several projects must be resolved before this (Hardwick 1996). This led to speculation about the fascicle can be completed. One project is a phylogeny Palafoxia feeder pOSSibly being a new species. When of the genus Schinia. Schinia is the most diverse in the the host plant distribution of Schinia regia was plot subfamily, currently with 112 species (Hardwick ted, it only corresponded with the moths collected in 1996). We have discovered taxonomic problems within eastern Texas. When Palafoxia sphacelata was plot closely related species or species complexes. These ted, it overlapped the distribution of the regia-like taxonomic problems must be resolved before a phy specimens. This finding led to further morphological logeny can be constructed. The most efficient way to study, and it was determined that the Palafoxia treat such a large genus is to define species groups feeder was a new species. within Schinia based on morphological characters within the context of a phylogeny. This paper ad MATEHIALS AND METHODS dresses one of these problems. The adult images were taken with a Kodak DSC 315 Schinia regia (Strecker), Schinia niveicosta (Smith), digital camera. The genitalic images were taken and Schinia regina, new species, form a compact through a Wild Photomakroskop dissecting micro group with a white forewing and gray, pinkish-purple, scope using a JVC KY-F70B digital camera.
