Succinea cleopatra Pallary, 1909

Du Sud Soudan; demande d'un ami (MSF) en poste là bas. Merci pour lui.

Aucune idée, c'est un ami collectionneur qui est Médecin Sans Frontière au SOUDAN qui cherche de l'aide pour ces coquilles ... Je vais essayer de le joindre ..pour en savoir plus. (La photo n'est pas terrible avec les moyens du bord qu'il doit avoir sur place)..

Donc j'ai eu les renseignements sur ces coquilles: taille 35 mm avec opercule fin et corné.

Autre info, trouvé dans eau stagnante ...

Après beaucoup de recherches, je pense avoir trouvé : Succinea cleopatra Pallary,1909

The shell is thin, fragile, dextral and somewhat transparent. It is elongated ovoid in outline with a short spire and blunt apex. The shell is not umbilicated and the spire is shorter than the aperture. The number of whorls varies from 3 to 4.
The whorls are spirally coiled and increase rapidly in height with a very narrow last whorl which is characteristic for {Succinea}. The sculpture includes uniform close set of fine oblique growth lines and the apparent sutures which separate the whorls. The aperture is large ovate and constitutes about 75% of the shell length. The outer lip is convex and the inner lip is highly applied to the columella.
Ecology
Biology Amphibious snail living sometimes on reeds in water and sometimes on damp ground. They climb aquatic plants, such as {Spirodela polyrhiza} and {Sphaeranthus suaveolens}.
Distribution Local: Along the River Nile and its tributaries from Upper Egypt to Rosetta and Damietta branches (Lower Egypt).
