Galba neotropica is a

mollusk
in the family Lymnaeidae, the pond snails.

This species was described as Lymnaea neotropica in 2007.[1] However, it belongs to the Galba/Fossaria group,[1][3] therefore this species is named Galba neotropica. cf.[2][3][4]

Galba neotropica is the vector typically responsible for

fascioliasis (liver fluke) livestock infection.[5]

Distribution

Galba neotropica was originally described from Lima, Peru and surroundings;[1] it appears to be a species restricted to South America, but with a very broad geographical distribution from Argentina in the Southern Cone north to Venezuela.[5]

The distribution of this species includes:

Description

The maximum length of the shell of this species is 10.36 mm.[5] Whorls are convex.[5] The columella is slightly curved and unfolded.[5]

An examination of tentacles, eyes and colour in living specimens has never performed.[5]

In the radula, the first bilateral teeth are bicuspid but occasionally they are tricuspid or rarely quadricuspid.[5] The praeputium/penis sheath length ratio is 1.10–3.90 mm (mean 2.12–2.70 mm).[5]

Two species that have a similar morphology are

cox1.[5]

Ecology

Galba neotropica is sometimes amphibious.[5] The habitat of Galba neotropica rarely[5] also includes artificial water bodies.[7]

These snails hatch from eggs. The shape of the egg cluster is rounded to oval when containing few eggs; when the clutch includes more eggs there is lengthening with a slight curving trend.[5] There are about 4–16 eggs in each cluster.[5]

Parasites of Galba neotropica include:

  • Fasciola hepatica.[6] The transmission capacity of Fasciola hepatica to humans is low, however, the transmission capacity of Fasciola hepatica to animals is high.[5]
