mtDNA universal primers

[Jose Lopez]

Have a look at O. Folmer et al (1994) DNA primers for amplification of
mitochondrial cytochrome oxidase subunit 1 from diverse metazoan
invertebrates.  Mol. Mar. Biol. and Biotech 3:294-299.

Steve Palumbi's PCR chapter in Molecular Systematics also has a few
invertebrate sequences for primers. 

Good luck!
