This study presents a multi-gene phylogenetic analysis of the Achatinoidea and provides an initial basis for a taxonomic re-evaluation of family level groups within the superfamily. A total of 5028 nucleotides from the nuclear rRNA, actin and histone 3 genes and the 1st and 2nd codon positions of the mitochondrial cytochrome c oxidase subunit I gene were sequenced from 24 species, representing six currently recognised families. Results from maximum likelihood, neighbour joining, maximum parsimony and Bayesian inference trees revealed that, of currently recognised families, only the Achatinidae are monophyletic. For the Ferussaciidae, Ferussacia folliculus fell separately to Cecilioides gokweanus and formed a sister taxon to the rest of the Achatinoidea. For the Coeliaxidae, Coeliaxis blandii and Pyrgina umbilicata did not group together. The Subulinidae was not resolved, with some subulinids clustering with the Coeliaxidae and Thyrophorellidae. Three subfamilies currently included within the Subulinidae based on current taxonomy likewise did not form monophyletic groups.
本研究对玛瑙螺总科进行了多基因系统发育分析，并为该总科内科级类群的分类重新评估提供了初步依据。从24个物种中对核rRNA、肌动蛋白和组蛋白3基因以及线粒体细胞色素c氧化酶亚基I基因的第1和第2密码子位置的总共5028个核苷酸进行了测序，这些物种代表了目前公认的6个科。最大似然法、邻接法、最大简约法和贝叶斯推断树的结果表明，在目前公认的科中，只有玛瑙螺科是单系的。对于拟阿勇蛞蝓科，费氏拟阿勇蛞蝓与戈克韦恩氏塞西蛞蝓分开，形成了玛瑙螺总科其他类群的姐妹分类单元。对于科利阿克斯科，布兰迪科利阿克斯和脐形梨蛞蝓没有聚在一起。细钻螺科没有得到解决，一些细钻螺类与科利阿克斯科和甲状腺螺科聚在一起。根据当前分类法目前包含在细钻螺科内的三个亚科同样没有形成单系类群。
