The vestiture, or hairlike projections of the cuticle, include macrotrichia (setae or setulae), which have an alveolus (socket), and microtrichia, which do not have an alveolus. Setae are the large macrosetae (bristles) that occur at typical positions on the head and thorax in Anastrepha and Toxotrypana. The postpronotal seta is the single seta usually present on the postpronotal lobe, the rounded rectangular sclerite on the anterolateral corner on the dorsum of the thorax.
