螺蛳属

分类学

螺蛳属的学名Margarya源于本属模式种Margarya melanioides样本的采集者A.R. Margary：他在中国云南洱海采集了本物种的标本，然后再由Nevill (1877) 描述。基于螺壳及螺肋的形态，张玺及齐锺彦于1949年首度修订本属，本辨识出本属有七个不同的物种。在这次修订里，张玺建立了两个螺蛳属的亚属，即：玺螺蛳亚属（Tchangmargarya）及Mabillemargarya亚属。The first molecular phylogeny showed that the genus Margarya is 多系群 and divided into three distinct clades.
Combining study of comparative morphology and molecular phylogeny, Zhang et al. revised the systematics of Margarya and recognized eight genuine extant species. However, only four species were found belonging to Margarya s. str., the rest species belonging to distinct genus Tchangmargarya or Anularya.
