The Eastern spinebill (), a passerine bird in the family (honeyeaters), a dominant group of birds in Australia and New Guinea. The aim of this study was to sequence the complete mitochondrial genome of the Eastern spinebill and use its sequence to better define the phylogeny of this species. The complete mitogenome sequence of was circular and 16,614 bp in length, and its architecture was conserved in comparison to other mitogenome sequences under the family . The Eastern spinebill mitogenome had the highest sequence identity with mitogenome sequences of two other honeyeaters, the white eared honeyeater, (84.9%) and the white-plumed honeyeater, (85.5%). The maximum-likelihood topology distinctly discriminated the Eastern spinebill sequence against all other species of the with significant bootstrap supports. We suggest the widespread sampling and complete mitogenome sequencing would be valuable in establishing the most accurate phylogenetic taxonomy of the family .
东部刺嘴莺（Eastern spinebill）是吸蜜鸟科（Meliphagidae）的一种雀形目鸟类，吸蜜鸟科是澳大利亚和新几内亚的主要鸟类群体。本研究的目的是对东部刺嘴莺的完整线粒体基因组进行测序，并利用其序列更好地确定该物种的系统发育。东部刺嘴莺的完整线粒体基因组序列呈环状，长度为16,614 bp，与吸蜜鸟科其他线粒体基因组序列相比，其结构保守。东部刺嘴莺线粒体基因组与另外两种吸蜜鸟——白耳吸蜜鸟（White-eared Honeyeater）和白羽吸蜜鸟（White-plumed Honeyeater）的线粒体基因组序列具有最高的序列同一性，分别为84.9%和85.5%。最大似然拓扑结构以显著的自展支持将东部刺嘴莺序列与吸蜜鸟科的所有其他物种明显区分开来。我们认为广泛采样和完整线粒体基因组测序对于建立吸蜜鸟科最准确的系统发育分类将是有价值的。
