Achryson surinamum
Achryson surinamum is a longhorn beetle in the subfamily Cerambycinae, first described by Carl Linnaeus in 1767. It represents one of the earliest described cerambycid species, reflecting its historical significance in entomological taxonomy. The species exhibits a broad geographic distribution across the Americas, from the southwestern United States through Central America to South America, including the West Indies.
Cilea silphoides
Cilea silphoides is a rove beetle (Staphylinidae: Tachyporinae) originally described by Linnaeus in 1767 as Staphylinus silphoides. It is the sole species of the genus Cilea treated in the 1975 North American revision by Campbell and Davies, which provided detailed morphological descriptions, distribution mapping, and male genitalia illustrations. The species has been taxonomically confused with related genera, and its name has undergone clarification regarding generic priority. It is distinguished from the related genus Coproporus by structural features of the male genitalia and external morphology.
Planaphrodes bifasciatus
Planaphrodes bifasciatus is a leafhopper species in the family Cicadellidae, first described by Linnaeus in 1758. It belongs to the large and diverse group of true bugs (Hemiptera) characterized by piercing-sucking mouthparts. The species is placed in the genus Planaphrodes, which is part of the leafhopper radiation within the suborder Auchenorrhyncha. As with many Cicadellidae, it is likely associated with vascular plants, though specific ecological details remain poorly documented in available sources.
Tragidion coquus
Tragidion coquus is a species of longhorn beetle in the family Cerambycidae, originally described by Linnaeus in 1758. It is among the larger and more visually striking cerambycids in North America, with velvety black and vivid orange coloration that mimics tarantula hawk wasps (Pompilidae). The species occurs broadly across the eastern and central United States, where it breeds in dead hardwoods, particularly oak. It is considered rare and difficult to encounter in the field despite its wide distribution.
