We expand previously published Lotka-Volterra model of the coexistence of sexual and gynogenetic forms of spined loach Cobitis hybrid complex by diffusion. We show that presence of sperm-dependent parthenogens is likely to negativelly affect the spatial expansion of sexuals, and hence the whole complex, compared to pure sexual population. Given that most of the known sperm-dependent asexual complexes are distributed in areas prone to climate-induced colonisation/extinction events, we conclude that such mechanism may be an important agent in determining the biogeography of sexual taxa and therefore requires further attention including empirical tests.
