Succinea approximans is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Succineidae, the amber snails.

Distribution

The type locality is in Puerto Rico.[1] Robert James Shuttleworth, the authority of this species mentioned six localities in his original description: "prope San Juan, Fajardo, Ceiba, Humacao, Luquillo et ad Rio Blanco".[1]

Other reports of Succinea approximans include:

Robinson et al. (2009) commented that it has not been reported from any intermediate islands.[3] They considered reports of this species by Thomas B. Bland (1869)[5] and George French Angas (1884)[6] to be dubious.[3]

Description

The dimensions of the shell of the type specimen are as follows: the height of the shell is 12 mm; the width of the shell is 7 mm; the height of the aperture is 9 mm.[1]

In Grenada, the height of the shell of this species is 10 mm.[2]

Ecology

The habitat of Succinea approximans ranges from relatively dry places to wet areas.[2] In Grenada, Succinea approximans lives among leaf litter.[2]
