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 edit
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 edit
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 Galba truncatula and Galba schirazensis.[5] Although several phenotypic characteristics are somewhat helpful for a preliminary specimen classification, a definitive classification of a specimen can only be obtained by the sequencing of at least one of the molecular markers used: ITS-2, ITS-1, 16S and cox1.[5]
Ecology edit
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]
