Male genitalia. Male pygofer with strong apical setae, usually with one or more spinelike apical processes. Subgenital plate broad and long, with 3–8 strong setae. Aedeagus usually with paired or unpaired processes on shaft or atrium, or both; shaft usually curved dorsad. Connective Y-shaped, stem longer than arms. Style apex usually footlike, preapical lobe strongly produced.
