1- Talitroides alluaudi(Alluaudi's landhopper)
Talitroides is a of terrestrial amphipod crustaceans commonly known as landhoppers or lawn shrimp. These small, laterally compressed crustaceans have adapted to life on land, inhabiting moist soil and leaf litter in forested environments. Several have been introduced outside their native ranges and have become established in new regions, including T. topitotum in Brazil and Hong Kong. The genus has been documented in mosquito surveillance bycatch studies and ecological research on soil fauna.

Habitat
Terrestrial; moist soil and leaf litter in forested environments. T. sylvaticus has been found in 52-year-old Pinus elliottii afforestation with high soil moisture and calcium content. T. topitotum occurs in Atlantic Forest in Brazil.
Distribution
Atlantic rain forests of southeastern Brazil (T. alluaudi and T. topitotum); Hong Kong (T. topitotum); Brazil (T. sylvaticus at Universidade Federal de Santa Maria); Florida Keys (Talitroides sp. recorded in mosquito surveillance bycatch).
Life Cycle
T. topitotum exhibits temperature-dependent development and mortality rates; breeding patterns have been modeled in ecological studies.
Behavior
T. alluaudi exhibits involving mechanical self-cleaning; the mechanics and patterns of this grooming have been described.
Human Relevance
Sampled as bycatch in mosquito surveillance traps, indicating potential for detection in standardized insect monitoring programs. T. topitotum is considered an in some regions where it has been introduced.
