The study material came from diverse regions of the states of Veracruz and Chiapas, Mexico. In females, several important differences among species were observed: in the number of ovarioles, morphology of the ventral receptacle, signum, spermathecae and aculeus. In males, differences were apparent in the accessory glands, ejaculatory apodeme of the sperm pump, distiphallus and surstyli. For the first time, the real location of the seminal vesicles is shown and the aedeagal gland is described. A comparative discussion ensues regarding terminology and the location of various struc-tures in both sexes. Key Words: Anastrepha, reproductive system, females, males, anatomy The genus Anastrepha includes 185 spe-cies occurring only in the Western Hemi-sphere. Despite the great diversity and wide distribution of this genus, most studies have concentrated exclusively on a few species of economic importance (Hernandez-Ortiz and Aluja 1993). Williamson's (1989) review and synthe-sis of studies of the descriptive anatomy of the reproductive system, oogenesis and spermatogenesis was limited to only a few fruit fly species. Studies of females of the following species have been published: Rhagoletis pomonella (Walsh) (Dean 1935), Ceratitis capitata (Wiedemann) (Hanna 1938, Valdez Carrasco and Prado Beltran 1990), Xanthaciiira unipuncta Malloch (Souza Lopes 1939), Bactrocera tryoni (Froggatt) (formerly Strumeta) (Drew 1969), Bactrocera oleae Gmelin (formerly Daciis) (Solinas and Nuzzaci 1984), as well as Rhagoletis nova (Schiner) and R. con-versa (Brethes) (Flores et al. 1987). For Anastrepha there is only general in-formation regarding the anatomy of the re-productive system in females for A. hidens (Loew) (Dampf 1933, Servin-Villegas and Jimenez-Jimenez 1995), for A. suspensa (Loew) (Dodson 1978) and for A. serpen-tina (Wiedemann) (Martinez et al. 1995). With respect to males, the information presently available consists of studies in C capitata (Hanna 1938, Anwar et al., 1971), X. unipuncta (Souza Lopes 1939) and B. tryoni (Drew 1969). The studies of Anas-trepha include species such as the follow-ing: A. suspensa (Dodson 1978), A. serpen-tina (Martinez et al. 1995), A. hidens (Ser-
