Systematics of the Chrysoxena Group of Genera (Lepidoptera
Tortricidae: Euliini)
Häftad, Engelska, 1991
337 kr
Skickas
The authors examine relationships within the Chrysoxena group of the tortricid tribe Euliini. They define 54 species among six genera: Chrysoxena Meyrick; Vulpoxena Brown, new genus; Thoridia Brown, new genus; Dorithia Powell; Cuproxena Powell and Brown, new genus; and Bidorpitia Brown, new genus. Using cladistic methods, the authors develop a phylogenetic hypothesis for the genera and species groups of Dorithia and Cuproxena. A systematic treatment of the included species provides appropriate generic assignment for several previously misplaced species and describes many taxa as new.

Systematics of Anopina Obraztsov (Lepidoptera Tortricidae: Euliini)
Häftad, Engelska, 2000
337 kr
Skickas
The authors revise the genus Anopina of the leafroller family, Tortricidae (Lepidoptera). This genus ranges from southern Canada to Costa Rica, with its greatest species richness in the higher elevations of Mexico. The larvae are suspected to be leaf-litter feeders. Sixty-two species are treated, of which forty-nine are described as new to science. The authors provide a hypothesis of phylogenetic relationships of the species, propose a classification, supply a key to species groups based primarily on features of the genitalia, and include illustrations of adults, larvae, and male and female genitalia.

Heliodinids are tiny, brightly colored dayflying moths. Phylogenetic relationships among genera of Heliodinidae are proposed using parsimony and character compatibility. We describe and illustrate 45 North and Central species (25 newly named) assigned to five genera (two new, two exhumed from synonymy). Larval host plants are recorded for 33 species (14 newly discovered), about 45% of the known fauna; 90% of these are specialists on Caryophyllales, primarliy Nyctaginaceae.

Insects boast incredible diversity, and this book treats an important component of the western insect biota that has not been summarized before - moths and their plant relationships. There are about 8,000 named species of moths in our region, and although most are unnoticed by the public, many attract attention when their larvae create economic damage: eating holes in woolens, infesting stored foods, boring into apples, damaging crops and garden plants, or defoliating forests.In contrast to previous North American moth books, this volume discusses and illustrates about 25 per cent of the species in every family, including the tiny species, making this the most comprehensive volume in its field. With this approach it provides access to microlepidoptera study for biologists as well as amateur collectors. About 2,500 species are described and illustrated, including virtually all moths of economic importance, summarizing their morphology, taxonomy, adult behavior, larval biology, and life cycles.
