Gammaridea
Gammaridea was historically recognized as a suborder of Amphipoda encompassing approximately 7,275 species (92% of described amphipods) across ~1,000 genera and ~125 families. The group included nearly all freshwater amphipods alongside numerous marine species. Taxonomic revisions by Lowry and Myers (2003–2017) demonstrated that Gammaridea was paraphyletic, leading to its deconstruction into new suborders: Corophiidea (2003), Senticaudata (2013), and Amphilochoidea (2017). The name Gammaridea is no longer recognized as a valid taxon in current amphipod classification.
Harpalitae
Harpalitae was historically recognized as a supertribe of ground beetles within the subfamily Harpalinae of family Carabidae. Following taxonomic reorganization of Carabidae, the supertribe designation fell out of use. The four tribes formerly grouped under Harpalitae are now classified directly under Harpalinae. The term persists primarily in older literature.
Toxotrypana
papaya fruit fly
Toxotrypana is an obsolete genus of tephritid fruit flies now synonymized with Anastrepha. The genus was historically recognized for species associated with papaya and related Caricaceae, with Toxotrypana curvicauda (now Anastrepha curvicauda) being the most studied species. These flies are significant agricultural pests in tropical and subtropical regions where papaya is cultivated.
