Whole genome sequencing  of Oxypoda opaca
DNA was isolated from a single specimen using a non-destructive extraction method described by Maruyama and Parker (2017). Illumina paired-end sequencing libraries were prepared using the Illumina TruSeq DNA library kits (paired-end 150bp reads, average insert size 155  105 bp) following the manufacturers protocol, quantified with Agilent Bioanalyzer High Sensitivity DNA kit and sequenced on HiSeq X platform.
