Parallel speciation is a special case of parallel evolution when two closely related lineages evolve traits that result in reproductive isolation independently in the same way.

Parallel Speciation Through Natural Selection
It has been thought for quite some time that speciation normally occurs when a species is subject to long periods of allopatry that later result in reproductive isolation, but recent studies have shown that speciation can occur through natural selection among separate populations in similar environments. Some conditions must be met however in order for parallel speciation to occur. The first condition being that the separate populations must be phylogenetically independent, second is that there must be reproductive isolation between the ancestral and descendent populations, and the last condition being that separate descendent populations inhabiting similar environments must not be reproductively isolated.
