我们提出了几乎完整的（16,007 bp）的线粒体基因组的Colossendeis megolonyx标本从南大洋，并讨论基因顺序和tRNA结构的比较系统发育的背景下。我们的数据表明，一个基础的立场，证实了早期的系统发育研究，但不同意最近发表的研究结果，支持一个高度衍生的姐妹群关系的Colossendeidae和Nymphonidae。我们的研究结果，再加上BLAST搜索和系统发育比较，表明在最近的一系列研究中，作为Colossendeis属的标本被错误鉴定。目前已被确认为一种拟步甲。(C)2010年爱思唯尔公司All rights reserved.
We present the almost complete (16,007 bp) mitochondrial genome of a Colossendeis megolonyx specimen from the Southern Ocean and discuss gene order and tRNA structure in a comparative phylogenetic context. Our data suggest a basal position of the colossendeid lineage corroborating earlier phylogenetic studies but disagreeing with results of a recently published study that supported a highly derived sister-group relationship of Colossendeidae and Nymphonidae. Our results, together with BLAST searches and phylogenetic comparisons, indicate that the specimen presented as Colossendeis sp. in a series of recent studies had been misidentified. It has now been identified as a nymphonid species. (C) 2010 Elsevier Inc. All rights reserved.
