Conspecific

Conspecific means "of the same species". This term is used commonly in discussions of organism migration. Conspecific plant and animal immigrant species are important genetic contributors as they commonly expand allele representation and increase group fitness in preexisting populations. Conspecific organisms may differ in variety, though they are all the same species.
