Euconulidae is a taxonomic family of minute, air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the superfamily Trochomorphoidea.[1]
This land snail family is closely allied to the Zonitidae, the glass snails.
Taxonomy[]
The family Euconulidae was originally placed within the superfamily Gastrodontoidea according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005).[2] Since 2017, its classification has been revised and it now belongs to the superfamily Trochomorphoidea[3]
Distribution[]
The distribution of the Euconulidae includes the Nearctic, the western-Palearctic, the eastern-Palearctic, the Neotropical zone, the Ethiopian zone, Malagasy, south-eastern Asia, Australia, Polynesia and Hawaii.[4]
Shell description[]
These minute snails have a shell which is roundly conical and broad-based, like the shape of an old-fashioned European woven bee hive or skep. For this reason these snails are sometimes known as "hive snails".
The shells of most Euconulidae are only about 3 mm in size, amber-colored and translucent.
Anatomy[]
In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).[5]
