Dyakiidae is a family of air-breathing land snails terrestrial pulmonate gastropod mollusks in the superfamily Trochomorphoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). [2]
Some of the species in this family are sinistral (left-handed) in their shell coiling.
The family Dyakiidae is endemic to Sundaland in Southeast Asia. [3]
In this family, the number of haploid chromosomes is between 26 and 30 (according to the values in this table). [4]
The family also includes Quantula striata , the only known terrestrial gastropod to emit light. [5]
The Digestive system characteristics are as follows. The 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] (These anatomical characteristics also include the family Staffordiidae which was considered part of the Dyakiidae at the time the study was done).
The family Dyakiidae includes the following 11 genera, with a steadily increasing number of described species (71 species until 2007 [6] + 11 new species in 2009 [7] ):
The following cladogram shows the phylogenic relationships of this family and superfamily with the other families within the limacoid clade: [11]

Dyakia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Dyakiidae.
Quantula striata, also known as Dyakia striata, is a species of medium-sized, air-breathing, tropical land snail. It is a terrestrial, pulmonate, gastropod mollusk in the family Dyakiidae. This species appears to be unique among terrestrial gastropods in that it is bioluminescent: Its eggs glow in the dark, and juveniles and most adults give off flashes of green light. It is the only species in the genus Quantula.
Elaphroconcha is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Dyakiidae.
Everettia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Dyakiidae.
