Euconulidae

The family Euconulidae was originally placed within the superfamily Gastrodontoidea according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005). Since 2017, its classification has been revised and it now belongs to the superfamily TrochomorphoideaBouchet P., Rocroi J.P., Hausdorf B., Kaim A., Kano Y., Nützel A., Parkhaev P., Schrödl M. & Strong E.E. (2017). Revised classification, nomenclator and typification of gastropod and monoplacophoran families. Malacologia. 61(1-2): 1-526

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.

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.Barrientos, Z. (2020). Microhabitat selection, and seasonal and daily activity of the snail Tikoconus costarricanus (Stylommatophora: Euconulidae) in tropical montane wet forest understory. Revista de Biología Tropical, 68(4), 1131-1142 There is also a preference of some parts of a leaf,Hernández-Quinta, M. (2013). Occupancy of strata of plant height and plant substrate by land snail (Gastropoda) assemblages at Escaleras de Jaruco, Mayabeque, Cuba. The Nautilus, 127(1), 29-35. 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.Moreno-Rueda, G., Ruiz-Ruiz, A., Collantes-Martín, E., & Arrébola, J.R. (2009). Relative importance of humidity and temperature on microhabitat use by land snails in arid versus humid environments. In A. Fernández-Bernal & M.A. De la Rosa (Eds.), Arid Environments and Wind Erosion (pp 331-343). Uni- ted Kingdom: Nova Science Publishers.

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.

In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).Barker G.
