Name

Dyakiidae Gude & Woodward, 1921

Rhinocochlis

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]

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).
Genera

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
Bertia Ancey, 1887 - only one species: Bertia cambojiensis (Reeve, 1860)
Dyakia Godwin-Austen, 1891 - type genus, 22 species
Elaphroconcha Gude, 1911 - 10 species
Everettia Godwin-Austen, 1891[8] - 15 species
Kalamantania Laidlaw, 1931 - only one species: Kalamantania whiteheadi (Godwin-Austen, 1891)[9]
Phuphania Tumpeesuwan, Naggs & Panha, 2007 - only one species: Phuphania globosa Tumpeesuwan, Naggs & Panha, 2007[6]
Pseudoplecta Laidlaw, 1932 - only one species: Pseudoplecta bijuga (Stoliczka, 1873)
Quantula Baker, 1941 - only one species: Quantula striata (Gray, 1834)
Rhinocochlis Thiele, 1931 - only one species: Rhinocochlis nasuta (Metcalfe, 1852)
Sasakina Rensch, 1930 - four species
