Notaris puncticollis
Pale-spotted gray weevil
Notaris puncticollis is a marsh weevil species described by LeConte in 1876. It belongs to the family Erirhinidae (sometimes historically placed in Brachyceridae or Curculionidae in various classifications). The species has a boreal transcontinental distribution and is primarily associated with wetland habitats. It is one of approximately 10 observed species in the genus Notaris.
Notiodes punctatus
Punctate Water Weevil
Notiodes punctatus is a species of marsh weevil in the family Erirhinidae, though it has historically been treated as a member of Brachyceridae. The species was described by LeConte in 1876 and is found in North America. Its common name, Punctate Water Weevil, references the punctate (spotted or pitted) surface texture characteristic of the species.
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.
Tanysphyrus ater
Tanysphyrus ater is a small weevil species described by Blatchley in 1928. It belongs to the family Erirhinidae (sometimes placed in Brachyceridae or Curculionidae in different classifications), a group of primitive weevils. The species epithet 'ater' refers to its black coloration. Very little published information exists on its biology or ecology, with only scattered collection records from North America.
