The complete mitochondrial genome (15,573 bp) of an understudied sheep parasite was sequenced and characterized. Its organization and characteristics, including the size, structure, gene order, start/stop codon usage and gene overlaps, are largely typical for Diptera. It exhibits very high A + T bias (81%). Posterior probability values in the inferred phylogenetic dendrogram were very high, but Oestroidea and Muscoidea superfamilies were both paraphyletic. The sequence was nested within the Oestridae clade, thus also rendering the family paraphyletic. A larger number of Hippoboscoidea mitogenomes will have to be available to achieve a better phylogenetic resolution.
对一种研究较少的绵羊寄生虫的完整线粒体基因组(15,573 bp)进行了测序和特征分析。其组织和特征,包括大小、结构、基因顺序、起始/终止密码子使用情况和基因重叠,在很大程度上是双翅目的典型特征。它表现出非常高的A+T偏向性(81%)。推断的系统发育树状图中的后验概率值非常高,但狂蝇总科和蝇总科都是并系的。该序列嵌套在狂蝇科分支内,因此也使该科成为并系的。必须有更多的虱蝇总科线粒体基因组才能实现更好的系统发育分辨率。
