获得了35个新腹足类的线粒体16 S rRNA基因全序列，以评估在家族内-超家族水平上的Buccinidae的系统发育关系。就科内属间关系而言，分子系统发育支持三个具有统计学意义的分支：Buccinum + Neptunea，Engina + Pisania + Pollia和Penion + Kelletia。这些分类通常与形态学和古生物学证据相一致。特别值得注意的是，Penion和Kelletia的单系性被确立。首次证实了它们作为反热带属的密切关系。巴比伦虫的位置远离其他布奇尼类，这证实了最近的形态学和分子学研究。目前的单系概念的Buccinidae是违反插入的nassariids和fasciolariids。
Complete mitochondrial 16S rRNA gene sequences from 35 caenogastropods were obtained to evaluate the phylogenetic relationship of the family Buccinidae at the intra-supra familial level. With respect to intergeneric relationships within the family, the molecular phylogeny supported three clades with statistical significance: Buccinum + Neptunea, Engina + Pisania + Pollia and Penion + Kelletia. These groupings are generally consistent with the morphological and paleontological evidence. In particular, it is noteworthy that the monophyly of Penion and Kelletia was established. Their close relationship as antitropical genera is confirmed for the first time. Babylonia was positioned remotely from the other buccinids confirming recent morphological and molecular work. The monophyly of the current concept of Buccinidae was violated by intercalations of nassariids and fasciolariids.
