The term ＇a.sorta.i.e ma.i.g＇ ha. been a.pli.d to descri.e two very di.ferent phenomena. （1） the tendency for i.di. vi.ua.s to choose phenotypi.a.ly si.i.a. ma.es from a.ong conspeci.i.s; or （2） the tendency to prefer conspeci.i. over hete- rospeci.i. ma.es （beha.i.ra. reproducti.e i.ola.i.n）. Both forms of a.sorta.i.e ma.i.g a.e wi.esprea. i. na.ure, but the rela.i.n- shi. between these beha.i.rs rema.0}s unclea.. Na.ely, i. i. pla.si.le tha. a.preference for phenotypi.a.ly si.i.a. conspeci.i.s i. ci.enta.ly reduces the proba.i.i.y of ma.i.g wi.h phenotypi.a.ly di.ergent heterospeci.i.s. We present a.model to ca.cula.e how the level of reproducti.e i.ola.i.n depends on i.tra.peci.i. a.sorta.i.e ma.i.g a.d the phenotypi. di.ergence between speci.s. For empi.i.a.ly rea.ona.le levels of i.tra.peci.i. a.sortment on a.si.gle tra.0} a.i., we show tha. strong reproducti.e i.ola.i.n requi.es very substa.ti.l phenotypi. di.ergence.
