| |
Mariaella beddomei is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Ariophantidae.
The specific name is in honor of Richard Henry Beddome.
Distribution
This species lives in India. It is endemic to Western Ghats.[2] Its localities include Travancore Hills.[3]
Shell description
The internal shell is thinner than in Mariaella dussumieri, shelly, flat and smooth beneath, white, with close, concentric lines of growth.[3] The length of the adult shell is 12 mm, the breath is 6.5 mm.[3]
Anatomy
The body of the animal varies greatly in color from uniform ochre to deep grey-black or spotted. There are no raised ridges on the shell-lobes. It is externally similar to Mariaella dussumieri, but larger, about 4 inches (100 mm) in length when fully extended.[3] It has more numerous teeth in the radula, the number in a row being 122 . 5 . 21 . 1 . 21 . 5 . 122 (148 . 1 . 148), and the shape differing somewhat. There are also differences in the genitalia, the spermatheca and the expansion in the free oviduct (ovitheca) having different forms.[3]
