Subfamilies

Athoracophoridae, common name the leaf-veined slugs, are a family of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the infraorder Stylommatophora, the stalk-eyed snails and slugs. Many of the species have an attractive pattern on their dorsal surface which resembles the veins in a leaf, hence the common name.

Athoracophoridae is the only family in the superfamily Athoracophoroidea.[2]

Leaf-veined slugs live on the various land masses and islands in the south-west Pacific area. In te reo Māori, leaf-veined slugs are known as putoko ropiropi.[3]

The scientific name Athoracophoridae is derived from prefix "a-", that means "without" and from a Greek word "θωραχοφὁρος" (thorachoforos), that means "breastplate".[1] This is a reference to the fact that the mantle in these slugs is small and not well delineated; it does not have the obvious, saddle-shaped or breast-plate-shaped appearance that it does in most other land slug groups.

Anatomy[edit]

In the family Athoracophoridae (in subfamily Aneitinae and in subfamily Athoracophorinae), the number of haploid chromosomes lies between 36 and 45 (according to the values in this table).[4] While they belong to the pulmonate snails, they lack a true lung. The vascularized mantle cavity is reduced, and a series of blind tubules radiate from it, being surrounded blood vessels. This allows for a more compact lung structure in these generally flat animals.[5]

Distribution[edit]

Species in this family are found in eastern Australia, New Zealand including its sub-Antarctic islands, Bismarck Archipelago, the Admiralty Islands, the New Hebrides, New Caledonia,[6] as well as on the Melanesian islands north to New Caledonia and New Britain, Papua New Guinea.

Taxonomy[edit]

The following two subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005),[2] that follows classification after Grimpe & Hoffmann (1925):[7]

The name Athoracophoridae has precedence over the name Aneitidae, because Athoracophoridae is in prevailing usage.[2]

Genera[edit]

Genera within the family Athoracophoridae include:[8]
