In 2003, Dr Wu and his colleagues noticed that there was morphological divergence appreciation between the western and eastern populations of Aegista subchinensi s separated by the Central Mountain Range, a major biogeographic barrier in Taiwan. They suggested that a cryptic species might be within Aegista subchinensis .
Aegista diversifamilia and A. subchinensis are also geographically separated by the Lanyang River, which makes this the first report suggesting that the Lanyang River is a biogeographic barrier for lowland appreciation terrestrial animals, appreciation said the scientists, who described the new species in the journal ZooKeys .
Huang C et al . 2014. Taxonomic revision of Aegista subchinensis (Möllendorff, 1884) (Stylommatophora, Bradybaenidae) and a description of a new species of Aegista from eastern Taiwan based on multilocus phylogeny and comparative morphology. ZooKey s 445: 31-55; doi: 10.3897/zookeys.445.7778
