Fluviopupa kessneri Ponder & Shea, 2014 

Diagnostic features

Shell elongate; operculum with few rudimentary pimples on inner side, no white smear; female lacking seminal receptacle; male with penial lobe in middle of penis. The stomach is very similar to that of the species of Fluviopupa, including the type species. The most obvious difference between the present species and other described species of Fluviopupa is the absence of a seminal receptacle.

Classification

Fluviopupa kessneri Ponder & Shea, 2014 

Class Gastropoda

Subclass Caenogastropoda

Order Littorinimorpha 

Superfamily Truncatelloidea

Family Tateidae

Genus Fluviopupa Pilsbry, 1911

Original name: Fluviopupa kessneri Ponder, & Shea, 2014. Ponder, W. F. and Shea, M. E. 2014. A new species of the Fluviopupa group (Caenogastropoda: Tateidae) from north-east Queensland, Australia, Molluscan Research 34: 71-78.

Type locality: Little Mulgrave River on Little Mulgrave Road, near bridge on Gillies Highway, Far North Queensland.

Biology and ecology

In roots along edges of side pond and main river, on leaves on gravel and in pockets of submerged leaves along the bank in shallow water and on sand in shallow water.

Distribution

This species appears to have a rather narrow distribution in the Mulgrave River and its tributary, Little Mulgrave River, as well as some of the small tributaries of these rivers, in north-eastern Queensland. It is likely, however, that this species is more widespread within the Little Mulgrave and Mulgrave Rivers and their tributaries than current sampling suggests.

Notes

This is the only species of Fluviopupa known outside certain Pacific islands (including Lord Howe Id), Papua New Guinea and New Caledonia.
