Abstract
The complete mitochondrial genome of Bionychiurus tamilensis Thunnisa & Sumithra, 2021 was sequenced, assembled, and annotated. The mitochondrial genome of B. tamilensis is 14,937 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. The overall nucleotide composition was 35.3% A, 15.8% C, 9.8% G, and 39.6% T, indicating an obvious A + T bias (74.9%). B. tamilensis was closely clustered with the following species of Onychiuridae: Allonychiurus kimi, Tetrodontophora bielanensis, Onychiurus orientalis, and Orthonychiurus folsomi.
