[...]Our results suggest that the parasitic morph of M. rubra may be an incipient species[...]

"In many ant species, queen size is dimorphic, with a large macrogynous morph (usually the normal morph) and a small microgynous morph. The significance of these morphs is rarely understood, but at least three explanations exist. First, the morphs may represent two dispersal tactics with macrogynes dispersing and microgynes filling up the area locally (Hölldobler and Wilson 1977). Some examples include Myrmica ruginodis (Elmes 1991), Ectatomma ruidum (Lachaud et al. 1999), Temnothorax rugatulus (Rüppell et al. 2001) and Mystrium rogeri (Molet et al. 2007). Unfortunately, no genetic differences have been searched between these morphs. Second, some microgynes are social parasites of the macrogynes and are genetically differentiated from their hosts. Examples include the microgynes of Myrmica rubra (Savolainen and Vepsäläinen 2003) and Ectatomma tuberculatum (Hora et al. 2005), now described as a distinct species (Feitosa et al. 2008). Third, the selfish larvae try to develop into gynes when they should become workers with limited or no reproductive capacity (Bourke and Ratnieks 1999; Beekman et al. 2003)."
