were used to amplify a 655 base
pair (bp) fragment of mtDNA from the 5 region of the CO1 gene
(Ward et al., 2005). A 810 bp region of nuDNA RAG2 was recovered
using the primer pair RAG2-f1 and RAG2-r3 (Westneat and Alfaro,
2005). Both CO1 and RAG2 sequences were analysed using all DNA
samples. The following gene fragments were analysed for a subset
of at least eight DNA samples. A 278 bp fragment of mtDNA from
the Cytb region was amplified using primer CB2H-15175 (Martin
and Palumbi, 1993) and a new light strand (L) primer for Sillago
(CBL-Sillago: 5-TTCTGGGGCTATGCTTGG-3). A 900 bp fragment of
mtDNA in the ATPase gene region was recovered using primers
