Pomacea diffusa, common name the spike-topped apple snail, is a species of freshwater snail, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails.

Taxonomy

Pomacea diffusa was originally described as a subspecies of Pomacea bridgesii.[1] Pain (1960)[2] argued that Pomacea bridgesii bridgesii was a larger form with a restricted range, with the smaller Pomacea bridgesii diffusa being the common form throughout the Amazon Basin (Brazil, Peru, Bolivia).[1] Cowie and Thiengo (2003)[3] suggested that the latter might deserve full species status, and the two taxa have been confirmed as distinct species by genetic analyses.[1]

Distribution

The type locality of Pomacea diffusa is in the city of Santa Cruz de la Sierra, Bolivia, although the species is widespread throughout the Amazon Basin.[1]

Non-indigenous distribution of Pomacea diffusa include:

Description

Two views of a shell of Pomacea diffusa

Pomacea diffusa is known as the spike-topped apple snail, because of its relatively raised spire.[1] It lacks a channeled suture, and overlaps in size with the Pomacea paludosa.[1]

An egg cluster of Pomacea diffusa

The egg masses have an irregular honeycombed appearance, like those of Pomacea haustrum, but are smaller and have a tan to salmon color, although the egg masses are white when freshly laid.[1]
