利用线粒体编码的细胞色素氧化酶亚基I(COI)DNA序列，研究了囊泡菌科(双瓣纲：囊泡菌科)之间的系统发育关系及其在异齿目中的位置。目前分析的泡囊藻类代表了最近的单系辐射，可能发生在新生代。核苷酸系统发育分析解决了与当前已知的物种一致的离散分支：Calytogena manma、C.ponderosa、Ectenagena extenta、C.phaseoliformis、Vesicomya cordata、Calytop genan。SP.(墨西哥湾)、C.kaikoi、C.nautilei、C.solidisma.和C.大豆(A型)。然而，标本不同地被鉴定为：V.Gigas，C.kirmeri，C.Pacillia，ANDV。鳞片有两个“物种复合体”，每一个都由多个进化谱系组成。大多数分类群仅限于热液喷口或冷泉栖息地，但“喷口”和“渗水”文蛤并不构成单独的单系群。目前该属的应用与系统发育推论不一致。
Phylogenetic relationships among vesicomyid clams (Bivalvia: Vesicomyidae) and their placement within the order Heterodonta were examined using mitochondrial encoded cytochrome oxidase subunit I (COI) DNA sequences. The presently analyzed vesicomyids represent a recent monophyletic radiation that probably occurred within the Cenozoic. Nucleotide phylogenetic analyses resolved discrete clades that were consistent with currently recognized species:Calyptogena magnifica,C. ponderosa,Ectenagena extenta,C. phaseoliformis,Vesicomya cordata,Calyptogenan. sp. (Gulf of Mexico),C.kaikoi,C. nautilei,C. solidissimaandC. soyoae(Type-A). However, specimens variously identified as:V. gigas,C. kilmeri,C. pacifica, andV. leptacomprised two “species complexes”, each composed of multiple evolutionary lineages. Most taxa are limited to hydrothermal-vent or cold-seep habitats, but the “vent” versus “seep” clams do not constitute separate monophyletic groups. Current applications of the generic namesCalyptogena,Ectenagena, andVesicomyaare not consistent with phylogenetic inferences.
