Interpretive Summary: There are more than 4,000 known species of fruit flies worldwide and more than 300 species in the United States and Canada. Some of our native species, such as the apple maggot, are important pests of fruit and vegetable crops, but the majority of the agriculturally important species are exotic. To be able to exclude these pests and to recognize them if they are introduced, we need to know what the native species are and how to recognize them. This paper deals with the North American species of a genus which are leaf-miners on composite plants (sunflowers and relatives). We describe 12 new species, tripling the number of known species, and provide taxonomic tools (key, descriptions, illustrations) so they can be recognized. The results of this paper will be important to ecologists, insect identifiers, taxonomists and conservationists.
Technical Abstract: The New World species of the genus Trypeta are revised, with a key, descriptions, illustrations, and phylogeny provided for the 18 species recognized: T. bifasciata, n. sp., californiensis, n. sp., chiapasensis, n. sp., concolor (Wulp), costaricana, n. sp., denticulata, n. sp., flaveola Coquillett, flavifasciata, n. sp., footei, n. sp., inclinata, n. sp., fractura (Coquillett), maculata, n. sp., maculosa (Coquillett), melanoura, n. sp., reducta, n. sp., rufata (Wulp), striata (Wulp), and wulpi, n. sp. Lectotypes are designated for Spilographa fractura Coquillett and Spilographa maculosa Coquillett. Trypeta (Acidia) tortile Coquillett and Acidia sigma Phillips are synonymized with Trypeta flaveola Coquillett. New host plant records are provided for five species, and host data and other information on the biology and immature stages of all of the New World Trypeta species are summarized and discussed.
