Triariodes
Triariodes is a genus of leaf beetles (family Chrysomelidae) established in 2019 by Clark & Anderson. The genus contains three described species: T. admiratio, T. segonku, and T. vittipennis (the latter transferred from another genus). As a recently described genus, published information on its biology and ecology remains limited. The genus is known from relatively few observations, with iNaturalist records indicating sparse detection in the field.
Tricholochmaea
Tricholochmaea is a genus of leaf beetles in the family Chrysomelidae, comprising 21 described species and two subspecies. Members are known as skeletonizing leaf beetles and flea beetles, feeding on plant foliage in a characteristic pattern that leaves leaf veins intact. The genus includes several species associated with specific host plants, such as the cherry leaf beetle (T. cavicollis), Pacific willow leaf beetle (T. decora), and blueberry leaf beetle (T. vaccinii). Taxonomic treatment varies, with some authors treating Tricholochmaea as a synonym of Pyrrhalta.
Walterianella
Walterianella is a genus of flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini) in the subtribe Oedionychina. The genus contains more than 40 described species distributed in the Neotropical region. Recent taxonomic revisions have transferred several species from related genera into Walterianella, establishing new combinations. Larval stages have been described for at least one species, Walterianella bucki.
