Mariaella dussumieri |
Mariaella dussumieri is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Ariophantidae.
Mariaella dussumieri is the type species of the genus Mariaella.
Its specific name is in honor of French merchant Jean-Jacques Dussumier.
Distribution
This species lives in India. It is endemic to Western Ghats.[2] In the Western Ghats it occurs as far north as the Kadur district of Mysore and perhaps to Mahableshwar. Hill-tracts of Ceylon.[3][unreliable source?] The type locality was Mahé, India, a small town between Calicut and Cannanore on the Malabar coast.[3]
This species has not yet become established in the USA, but it is considered to represent a potentially serious threat as a pest, an invasive species which could negatively affect agriculture, natural ecosystems, human health or commerce. Therefore, it has been suggested that this species be given top national quarantine significance in the USA.[4]
Shell description
The internal shell in general thin, slightly convex, ovate and white. The apex of the shell is forming a small point at the right side and near the posterior end. The shell is not involute.[3]
Anatomy
The color of the animal is yellowish brown or olivaceous, sometimes almost black, and generally mottled with dark blotches.[3] The mantle has two narrow raised ridges on the shell-lobes, one running from the little shell-aperture round the left margin of the shell, the other towards the respiratory orifice on the right margin.[3] The size appears to vary up to about 8 inches (200 mm) in length.[3] Teeth of radula in one specimen were 88.3.20.1.20.3.88 (111.1.111), in another 95.2.18.1.18.2.95 (115.1.115).[3]
