Abstract
Abstract The complete sequence of the mitochondrial genome and fifteen microsatellite loci for the Chilean kelp crab Taliepus dentatus are reported for the first time. The DNA assembly obtained from an Illumina sequencing revealed a complete mitochondrial genome of 15 603 bp in length. The gene composition and arrangement were similar to that reported for most decapod crabs, containing 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a non-coding region. A phylogeny performed with 10 species obtained from GenBank placed T. dentatus close to individuals of the Family Epialtidae. From the 6397 repeated sequences encountered in the data, 15 microsatellite loci primers were designed and five tested for variability in specimens obtained from two sampling sites separated by 300 km of distance. The mean number of alleles per locus was nine (5–15 alleles per locus) and the observed heterozygosities ranged from 0.34 to 0.8. Departure from Hardy–Weinberg equilibrium was observed in two out of the five microsatellites, while none of the loci exhibited significant linkage disequilibrium. This genetic resource will be useful for phylogeny, population genetics and parentage analysis of the commercial species T. dentatus.
