The mitochondrial genome of Bothriocyrtum californicum (O. Pickard-Cambridge, 1874) has been completely sequenced and annotated for the first time. This trap-door spider is found in California, United States. We used SPAdes to assemble contigs and the mitogenome was extracted from the resulting contigs. The mitogenome was annotated using MITOS2 and by comparing to other species in the order Araneae. The mitogenome is 14,081 base pairs, and includes 22 transfer RNA (tRNA) genes, 13 protein coding genes (PCG), 2 ribosomal RNA (rRNA) genes, and a control region. This is the first sequenced and annotated mitogenome for this species, genus, and the family Halonoproctidae.
