'''''Renea moutonii singularis''''' is a [[subspecies]] of [[land snail]] with an [[Operculum (gastropod)|operculum]], a [[terrestrial animal|terrestrial]] [[gastropod]] [[mollusk]] in the family [[Aciculidae]].<ref  name="iucn" /> It was described by Pollonera in 1905.  The common name is needle snail.<ref>Conchology Inc http://www.conchology.be/?t=68&u=824619&g=fd769883d258b1abcd889fd40a63f641&q=99b5128779de6c5043dc19891a988bcc retrieved 12 June 2015</ref>

==Distribution==

This subspecies is [[Endemism|endemic]] to [[List of non-marine molluscs of France|France]]. It has a very narrow distribution, being found only in the [[Alpes-Maritimes]], in the Loup and Siagne valleys.<ref name = goett>Goettingen University AnimalBase http://www.animalbase.uni-goettingen.de/zooweb/servlet/AnimalBase/home/species?id=2827 retrieved 12 June 2015</ref> Because of its limited distribution and rarity within its range it is considered threatened. The IUCN red list of endangered species lists it as vulnerable.<ref name="iucn" />

==Description==

These snails are between 3 and 4&nbsp;mm long and 1.1 to 1.3&nbsp;mm wide. Their elongated shells are light brown with fine ribbing (60-70 ribs with a penultimate whorl). The apertural margin in lateral view is oblique / and (-shaped, with an exaggerated {{not a typo|sinulus}}, and a P-like opening at the suture in the last quarter of the last whorl. There is no cervical callus.  The apertural margin can be thick.<ref name = goett/>

''Renea moutonii singularis'' is possibly the end of an evolutionary line that begins with an almost straight apertural margin (in lateral view) towards a much more oblique and protruded margin with the needle snail having the longest {{not a typo|sinulus}} along the suture.<ref name = goett/>
