*Tandem repeat identified in the sequence from whole genome sequencing.
†Six C. cayetanensis specimens were used in initial evaluation of PCR primers: specimens 22231, 22234, 22238, and 28709 were used to evaluate PCR primers from loci CYC3, whereas specimens 22231, 22234, 24550, and 24552 were used for PCR primers from the remaining loci.
