Dyakiidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Dyakioidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[2]
Dyakiidae is the only family in the superfamily Dyakioidea.[2] This family has no subfamilies.[2]
Contents
Distribution
The family Dyakiidae is endemic to Sundaland in Southeast Asia.[3]
Anatomy
In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).[4]
The family also include Quantula striata, the only known terrestrial gastropod to emit light.[5]
Digestive system characteristics: Buccal mass is small. The jaw is smooth. The stomach is very simple with weak muscles (as is the case in the majority of land snails).[4] (This anatomy characteristics include family Staffordiidae as as a part of Dyakiidae).[clarification needed]

The family Dyakiidae includes the following 11 genera, with altogether 82 species (71 species up to 2007[6] + 11 new species in 2009[7]):
- Asperitas Gray, 1857 - 14 species
