First Report of Anastrepha Compressa in Mexico and New Records for Other Anastrepha Species in the Yucatan Peninsula (Diptera: Tephritidae)

Tephritid flies (Diptera: Tephritidae) are known as "true fruit flies" due to the close relationship between their immature stages and their wild and domesticated host plants.They are the most important dipteran pests of agriculture worldwide (Christenson & Foote 1960) and include 481 genera and 4352 species (Norrbom et al. 1998).Anastrepha is the most economically important and diverse genus of fruit flies in the Americas, with 197 species distributed throughout tropical and subtropical areas (Norrbom et al. 2000).To date, 32 species are known to occur in Mexico, and seven of them have been reported for the Yucatan Peninsula (YP).This includes the Mexican states of Campeche, Quintana Roo and Yucatan.Anastrepha species reported for each state are: Campeche ( Anastrepha fraterculus, A. hamata, A. limae, A. obliqua, A. serpentina ); Quintana Roo ( A. hamata, A. ludens, A. obliqua, A. serpentina ); and Yucatan ( A. fraterculus, A. ludens, A. serpentina, A. striata ) (Hernández-Ortiz 1992).This work provides new locality records for Anastrepha species already reported for YP, first records of three species in YP ( A. ampliata, A. pallens and A. spatulata), and the first record of A. compressa for Mexico.Material examined is deposited at the Colección de Insectos, Instituto de Ecología A.C. Xalapa, Veracruz (IEXA), and Colección Entomológica Regional of the Universidad Autónoma de Yucatán (CER).
