Exosphaeroma inornata
Exosphaeroma inornata is a sphaeromatid isopod originally described by Dow in 1958 from California. The species was later synonymized with E. media George and Stromberg 1968 from San Juan Island, Puget Sound, with differences between original descriptions attributed to author errors or phenotypic variations. It is a wide-ranging intertidal species with documented occurrence from San Diego, California north to San Juan Island, Washington, though a significant distribution gap exists between Humboldt Bay and Puget Sound.
Liodessus
Liodessus is a genus of small diving beetles in the family Dytiscidae, tribe Bidessini. Species occur across the Americas from North America through the Andes to southern South America, with notable diversity in high-altitude wetlands and páramo ecosystems. Many species inhabit shallow, exposed pools and temporary water bodies, showing phenotypic plasticity in body form correlated with habitat permanence. The genus contains numerous species, with several new species described from the high Andes of Peru and Colombia in recent years. Taxonomic resolution relies heavily on male genital morphology.

cereal flies, frit flies
Thaumatomyia is a genus of small flies in the family Chloropidae, commonly known as cereal flies or frit flies. The genus includes species with divergent larval ecologies: some are predatory on root aphids in agricultural soils, while others have been observed feeding on plant exudates. Several species are recognized as important biological control agents of root aphids in sugar beet and cereal crops in Middle Asia.
