Classification edit
As species in the genus Perdicella differ from those of Partulina largely on the basis of size, and species in the genus Perdicella occur on separate branches, this suggests that dwarfism may have evolved multiple times across the species complex. [2]
Distribution edit
Perdicella Helena, both species found on Molokaʻi, grouped together on a separate branch from Perdicella helena found on Maui, and Partulina variabilis and Partulina semicarinata, species endemic to Lanaʻi. This species has been known to enter the islands by getting stuck to feathers of birds or floating tree trunks that found their way to Hawaii. [3]
Habitat edit
The Perdicella Helena live in terrestrial areas. They are found on the trunk, stems & leaves of certain non-pubescent plants that have necessary fungi. Perdicella Helena are found on trunk, stems & leaves of certain non-pubescent plants. [4]
Description edit
Perdicella helena is a species of tropical tree-living, air-breathing, land snails, arboreal pulmonate gastropod mollusks in the family Achatinellidae. This species is endemic to Hawaii in the United States. [5]They fall under the Achatinellids in which are considered endangered.[citation needed] These snails are flat and round with a shell diameter of 3-10 mm. They can be found on the ground and in the vegetation. [6]
