Revision of the schausi Group of Anastrepha Schiner (Diptera: Tephritidae), with a Discussion of the Terminology of the Female Terminalia in the Tephritoidea

Monophyly of a group of four species of Anastrepha is proposed based on characters of the head and the male terminalia. The group includes A. schausi Aldrich; A. fernandezi Caraballo; A. hermosa Norrbom, n. sp.; and A. bellicauda Norrbom, n. sp. Sexual dimorphism in these species is noted. A discussion of morphological terminology in the Tephritoidea, especially concerning female terminalia, is presented.
