Considering non-degenerate, backward quasi-phase matched parametric interaction in the presence of dissipation and dispersion, we show that quadratic media support a novel type of symbiotic solitary-wave attractor. We study the spontaneous generation of the new solitary waves and identify a velocity selection mechanism. The selected velocity depends on the injected continuous-pump intensity and can take any subluminous value (positive or negative). As a particular case, we point out a new mechanism of energy localization through the zero-velocity symbiotic solitary wave which is spontaneously generated from noise fluctuations.
