A systematic revision of the New World species of <i>Trypeta</i> Meigen (Diptera: Tephritidae)

Abstract

Abstract. The tephritid genus Trypeta is revised for the New World and a key, descriptions, illustrations, and phylogeny provided for the eighteen species recognized: Trypeta bifasciata , sp.n. , californiensis , sp.n. , chiapasensis , sp.n. , concolor (Wulp), costaricana , sp.n. , denticulata , sp.n. , flaveola Coquillett, flavifasciata , sp.n. , footei , sp.n. , fractura (Coquillett), inclinata , sp.n. , maculata , sp.n. , maculosa (Coquillett), melanoura , sp.n. , reducta , sp.n. , rufata (Wulp), striata (Wulp), and wulpi , sp.n. Lectotypes are designated for Spilographa fractura Coquillett and Spilographa maculosa Coquillett. Trypeta (Acidia) tortile Coquillett, Acidia sigma Phillips, and Trypeta angustigena Foote are synonymized with Trypeta flaveola Coquillett. Based upon many specimens, we redefine Trypeta flaveola as a widely distributed and morphologically highly variable species. 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. Our phylogenetic analysis suggests that the majority of New World Trypeta species form a monophyletic group that diversified in the southwestern U.S.A. and Mesoamerica.
