Abstract

Penicillidia dufourii (Westwood 1834) is a specialized parasite categorized under family Nycteribiidae that prefers to parasitize the body surface of various bats under the genus Myotis. Many species of the family Nycteribiidae are carriers of various pathogens; however, research on P. dufourii remains scarce, and studies on its molecular identification and population genetic structure are still lacking. In this study, the complete mitochondrial genome of P. dufourii was elucidated for the first time using Illumina sequencing. The mitochondrial genome is 15,354 bp in size and encodes approximately 37 genes, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. Analysis of 13 protein-coding genes revealed that UUA, UCA, CGA, and GGA were the most common codons, while nad4L had the fastest evolutionary rate and cox1 the slowest. Phylogenetic analysis based on the mitochondrial genome indicated that P. dufourii is clustered with other species of the family Nycteribiidae and is most closely related to Nycteribia parvula and Phthiridium szechuanum.

Penicillidia dufourii（双翅目：Hippoboscoidea：Nycteribiidae）的完整线粒体基因组及系统发育关系。

Penicillidia dufourii（Westwood 1834）是一种专门的寄生虫，被归类为蝙蝠科（Nycteribiidae），喜欢寄生在蝙蝠属（Myotis）各种蝙蝠的体表。Nycteribiidae 科的许多物种都是各种病原体的携带者，但对 P. dufourii 的研究仍然很少，对其分子鉴定和种群遗传结构的研究仍然缺乏。本研究首次利用 Illumina 测序技术阐明了 P. dufourii 的完整线粒体基因组。线粒体基因组大小为 15,354 bp，编码约 37 个基因，包括 13 个蛋白编码基因、22 个 tRNA 基因、2 个 rRNA 基因和 1 个控制区。对 13 个蛋白编码基因的分析表明，UUA、UCA、CGA 和 GGA 是最常见的密码子，而 nad4L 的进化速度最快，cox1 的进化速度最慢。基于线粒体基因组的系统进化分析表明，P. dufourii 与 Nycteribiidae 科的其他物种聚类，与 Nycteribia parvula 和 Phthiridium szechuanum 的亲缘关系最为密切。
