Pictoneritina Iredale, 1936


Subgenus Pictoneritina Iredale, 1936 

Type species. By original designation, Neritina oualaniensis Lesson, 1831  .

Recent, in estuaries and brackish lagoons, Indo-Pacific.

Diagnosis. Shell small, 3 to 15 mm in height, smooth; septum weekly arched with one large, several small teeth.

Remarks. In the absence of a detailed description by Iredale (1936) the above diagnosis has been based on that given by Keen (1960). In the type species, the large tooth is about a third of the distance from the apical end of the septum with up to 5 small teeth abapical to it. The shell is glossy and the colour patterns are very variable.
