Comm.: This cosmopolitan genus is comprised of 42 species, 29 of which have been described from the Neotropics (Curler & Jacobson 2012, Santos et al. 2009a, 2013b), generally associated with primary forests (Wagner & Stuckenberg 2012). Quate & Alexander (2000) presented a synopsis of the New World species, including a key for the identification of males, which was followed by a revision of the genus worldwide by Williams (2003). For this reason only references published after the latter catalogue are cited below. Five species are recorded from Colombia.
