The Endodontidae are a family from the suborder of the land snails (Stylommatophora), which is mainly found in the southern hemisphere . Many species are or were endemic to smaller and larger islands in the Indo-Pacific . However, due to the introduction of predatory snail species, a significant proportion of these species has already become extinct.
features
The representatives of the family Endodontidae have small to large housings ; but the housings are never reduced. They are usually flattened and the navel is usually wide and open. In some taxa the umbilical opening can be narrowed secondarily; the umbilical space serves as a breeding chamber for the eggs. The surface is ornamented with radial elements, but these can disappear on the adult part of the case. The mouth is originally reinforced on all sides with lamellae and folds, which can also end in "teeth" that are directed outwards. The reinforcement can be reduced to a greater or lesser extent in some taxa, or even absent. The eyes are always well developed. A longitudinal furrow between the body and the sole of the foot (pedal longitudinal furrow) and another longitudinal furrow above the foot (suprapedal furrow) unite at the end of the tail, but without the formation of a so-called “caudal horn” or an enlarged mucus pit.
Geographical distribution
The family occurs on the Pacific Islands, New Guinea, Indonesia, Japan, the Philippines, India, South and East Africa, Madagascar, South America and the South Atlantic island of St. Helena .
Systematics
Bouchet & Rocroi (2005) do not exclude any subfamilies, whereas Schileyko divides the family Endodontidae into three subfamilies, the nominate subfamily Endodontinae and the subfamilies Trachycystinae Schileyko, 1986 and Thysanotinae Godwin-Austen, 1907.The latter two subfamilies are described by Bouchet & Rocroi (2005) placed as subfamilies to the family Charopidae .
