Eustala
humpbacked orb-weavers
Eustala is a genus of orb-weaver spiders in the family Araneidae, first described by Eugène Simon in 1895. As of November 2024, the genus contains 87 species distributed primarily across the Americas, from the United States through Central America to South America, with highest diversity in Brazil, Uruguay, and Argentina. Several species have been documented exhibiting specialized ecological relationships, including myrmecophily (living among ants) in Central American species that inhabit ant-defended acacia plants. The genus includes the well-known humpbacked orb-weaver, Eustala anastera, found across North and Central America.

Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

Oreoneta
A genus of dwarf spiders (family Linyphiidae) established in 1894, comprising approximately 30 species distributed across cold-temperate and Arctic regions of the Northern Hemisphere. Most species inhabit high-latitude or high-altitude environments. The genus was revised extensively by Saaristo & Marusik in 2004, resulting in numerous new species descriptions.
