Terminal segment with four pairs of papillae, all with setae of similar length ( Fig. 3E).

Damage. Larvae of Dasineura capsicicola attack flower buds of pepper, causing lesions in the anthers and ovaries. Externally, attacked buds can be recognized by the violet col- or of the corolla (see figures in Guimarães and Moura 2018).

Etymology. The word “ capsicicola ” refers to the specific epithet of the host plant.
