Males undergo a profound transformation when they reach
sexual maturity, turning from the "leucomorph" state to the "anamorph" state. Before this transformation was recognised in 1983,
females and immature males were described in the genus ''Leucothoides'' (Leucothoidae), and mature males were described in the genera ''
Anamixis'', ''
Paranamixis'' and ''
Nepanamixis'' (Anamixidae). The genus ''Leucothoides'' may still be used for leucomorphs of species whose anamorph has not yet been identified.
