• Lampropteryx

  Lampropteryx is a genus of geometrid moths in the subfamily Larentiinae, established by English entomologist James Francis Stephens in 1831. The genus name derives from Greek roots meaning "bright wing," referring to the characteristic glossy sheen on the forewings. The genus contains at least nine described species distributed across the Palearctic region, including the well-known water carpet (L. suffumata) and Devon carpet (L. otregiata).

• Penichroa fasciata

  Penichroa fasciata is a species of longhorn beetle in the family Cerambycidae, subfamily Cerambycinae, and tribe Graciliini. It was described by Stephens in 1831. The species has a broad distribution spanning Europe and northern Asia (excluding China) as well as North America, though specific details of its biology and ecology remain poorly documented in the available literature.

• Procas

  Procas is a Holarctic genus of weevils (Coleoptera: Erirhinidae) established by Stephens in 1831. The genus comprises six recognized species distributed across the western Palaearctic (four species), eastern Palaearctic (one species), and Nearctic (one species). Species-level identification relies partly on male sternite 8 characters, a technique first applied to this genus in a 2004 revision. Recent taxonomic work has clarified synonymies and restored related genera Notodermus and Apachiscelus from synonymy with Procas.
