Gudeodiscus giardi is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Plectopylidae.

This species was described by French zoologist Pierre Marie Henri Fischer (1865-1916) (son of Paul-Henri Fischer) in 1898.

Subspecies

The specific name giardi is in honor of French zoologist Alfred Mathieu Giard. [2] The subspecific name oharai is in honor of the collector Kenji Ohara. [3] The subspecific name szekeresi is in honor of the malacologist Miklós Szekeres. [3]

Distribution

The distribution of Gudeodiscus giardi includes Cao Bằng Province and the northern part of Lạng Sơn Province in Vietnam [1] and western Guangxi in China. [3]

The type locality of Gudeodiscus giardi giardi is "Cao-Bang". [2] [1] Gudeodiscus giardi giardi lives in Vietnam and China. [3] Gudeodiscus giardi oharai lives in are north of Nanning in Western Guangxi, China. [3] Gudeodiscus giardi szekeresi live in the type locality only: Langur Reserve, 25 km southeast of Chongzuo, China. [3]

Description

The most important shell characters for identification of Gudeodiscus giardi include: high and rather sharply defined shell shape, narrow umbilicus (for the genus Gudeodiscus) and thick peristome. [1]

The size of the shell is small to large. [1] The shape of the shell is high and rather sharply defined. [1] The color of the shell is brownish, but some Chinese populations are small and yellow and translucent. [1] The sculpture is usually finely reticulated, that is resulting in a matt surface. [1] The umbilicus is deep. [1] Apertural lip, callus and apertural fold are very well-developed (callus is very much elevated). [1] Parietal wall has two lamellae. [1] The anterior lamella is usually connected to the lower plica. [1] Middle palatal plicae are short, depressed Z-shaped, or almost vertical, sometimes connected to each other. [1] The width of the shell 13.5–21.3 mm. [1] The height of the shell is 7.0–12.1 mm. [1]

The radula of Gudeodiscus giardi has 12 lateral teeth and 15 marginal teeth. [1] The size of the central tooth is as large as the ectocone of the first lateral. [1] The shape of the first lateral is rhomboid and pointed. [1] Marginal teeth are bicuspid or tricuspid with blunt inner cusp and shallow incision between the inner two cusps. [1]

The reproductive system of specimen from China was described by Páll-Gergely & Asami in 2014 [4] and from Vietnam by Páll-Gergely et al. in 2015. [1] Embryos were not recorded in the uterus. [1] There were recorded hook-like or flat and oval calcareous granules on the internal surface of penis. [1]

Ecology

It is a ground-dwelling species as all other plectopylid snails in Vietnam. [1]

It co-occur with other plectopylids in Vietnam: with Gudeodiscus anceyi , Gudeodiscus francoisi , Sicradiscus mansuyi and with Gudeodiscus suprafilaris . [1] Gudeodiscus phlyarius live at geographically close sites to Gudeodiscus giardi. [1]
