摘　　要：1 Introduction The intriguing relationship between sexual selection and speciation has sparked an increasing number of pa- pers in recent years that have attempted to draw connec- tions between the two processes. These include a myriad of theoretical and empirical studies, as well as several influential reviews （e.g. Price, 1998; Panhuis et al., 2001, Kirkpatrick and Ravign6, 2002; Ritchie, 2007; Maan and Seehausen, 2011）. In particular, many re- searchers have speculated on whether sexual selection can lead to speciation, either alone, or in conjunction with ecological processes. Such speculation is tempting in part because of the obvious differences in secondary sexual characters that often exist between closely re- lated species. Indeed one of the earliest and most influ- ential of all sexual selection models, Lande＇s （1981） paper ＂Models of speciation by sexual selection on a polygenic trait＂ centered its title on the role that sexual selection may play in speciation.
