Mayetia
Mayetia is a genus of minute rove beetles (Staphylinidae: Pselaphinae) in the tribe Mayetiini. The genus includes at least three macropterous and macrophthalmic species, a rare wing and eye configuration in this predominantly wing-reduced group. Mayetia atlantica, described from the Brazilian Atlantic Forest, represents the first Brazilian record of the tribe and the southernmost occurrence of the genus in the New World. Most species in the genus remain poorly known, with limited biological data available.
Stenocranus
delphacid planthoppers
Stenocranus is a genus of delphacid planthoppers in the family Delphacidae, containing more than 70 described species. Species within this genus exhibit wing polymorphism, with macropterous (long-winged) and sub-macropterous forms occurring in at least some species. Several species are documented crop pests, particularly of corn, rice, and sugarcane. The genus has a broad distribution with records from Europe, North America, and Asia, though individual species vary in their geographic ranges. Some species have shown invasive potential, with range expansions into new regions documented in recent decades.
