Euconulidae is a

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

Neotropical zone, the Ethiopian zone, Malagasy, south-eastern Asia, Australia, Polynesia and Hawaii.[4]

Humidity, temperature, rainfall, and foliar dripping derived from dew, mist, and rain, affect the behavior and substrate selection of small terrestrial molluscs, such as Tikoconus costarricanus, which inhabit shrubs in humid tropical montane forests.[5] There is also a preference of some parts of a leaf,[6] for example, in some cases the lower side is preferred, possibly because it has better humidity and protects small snails from the impact of raindrops.[7]

Shell description

These minute snails have a

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).[8]
