Aramigus tessellatus
Aramigus tessellatus is a species of broad-nosed weevil in the family Curculionidae, subfamily Entiminae. The species was originally described by Thomas Say in 1824 under the basionym Liparus tessellatus. It belongs to the tribe Naupactini, a group of weevils primarily distributed in the Americas. Distribution records indicate presence in Argentina, Brazil, and Chile, suggesting a South American range. As with many entimine weevils, adults likely feed on plant foliage, though specific host associations for this species remain poorly documented.
Atrichonotus
Atrichonotus is a genus of broad-nosed weevils (family Curculionidae) comprising nine described species. The genus was established by Buchanan in 1939 and is classified within the tribe Naupactini. At least one species, Atrichonotus taeniatulus, has been introduced and established in New Zealand from its native South American range. The genus is part of the diverse Entiminae subfamily, commonly known as broad-nosed or root weevils.
Ericydeus
broad-nosed weevils
Ericydeus is a genus of broad-nosed weevils (Curculionidae: Entiminae: Naupactini) containing 16 described species distributed from the United States through Central America to Argentina. The genus was revised in 1995, revealing distinct biogeographic patterns: South American species form one clade and Central/North American species form another, with character evolution following a southern-to-northern direction. Species exhibit varied coloration including metallic green, coppery, and punctate patterns.

Ericydeus lautus is a species of broad-nosed weevil in the beetle family Curculionidae. It was first described by LeConte in 1856. The species belongs to a predominantly New World genus distributed from North America through Central America to South America. Phylogenetic analysis places E. lautus in a clade with other North and Central American species, distinct from South American congeners.
Ericydeus placidus
Ericydeus placidus is a species of broad-nosed weevil in the family Curculionidae. It belongs to the tribe Naupactini, a group of New World weevils. The species was described by Horn in 1876 and is currently accepted as valid. Very little specific information has been published about its biology or ecology.
Naupactus
White-fringed Weevils
Naupactus is a large genus of weevils in the family Curculionidae, commonly known as white-fringed weevils. The genus comprises exclusively Neotropical species, several of which have been introduced to other regions and become significant agricultural pests. Members of this genus are characterized by reduced humeri and lack of metathoracic wings, traits formerly used to separate them into the genus Graphognathus before taxonomic revision. Some species exhibit parthenogenetic reproduction, and flightless adults are common.
Naupactus pallidus
Naupactus pallidus is a species of broad-nosed weevil in the family Curculionidae, subfamily Entiminae. It belongs to the diverse Neotropical genus Naupactus, commonly known as white-fringed weevils. Species in this genus are characterized by their elongated bodies, distinct rostrums, and often pale or whitish markings on the elytra. Many Naupactus species have become agricultural pests, with some introduced to North America.
Naupactus peregrinus
Naupactus peregrinus is a species of broad-nosed weevil in the family Curculionidae, subfamily Entiminae. It belongs to the large Neotropical genus Naupactus, commonly known as "white-fringed weevils." The species has been recorded from the southeastern United States (Alabama, Arkansas, Florida) and parts of South America (Chaco, Entre Ríos in Argentina). Like other members of its genus, it is likely associated with vegetation and may have been introduced to some regions, though specific ecological details remain poorly documented.
Pactorrhinus
Pactorrhinus is a genus of broad-nosed weevils in the beetle family Curculionidae, established by Ancey in 1881. The genus belongs to the tribe Naupactini within the subfamily Entiminae. Only one described species is currently recognized: Pactorrhinus grisescens.
Pactorrhinus grisescens
Pactorrhinus grisescens is a species of broad-nosed weevil in the family Curculionidae, described by Ancey in 1881. It belongs to the tribe Naupactini, a group of root-feeding weevils. The species has been recorded in North America, though detailed biological information remains scarce.
Phacepholis
Phacepholis is a genus of weevils in the family Curculionidae, subfamily Entiminae, and tribe Naupactini. It was established by George Henry Horn in 1876. The genus belongs to the broad-nosed weevil group, characterized by a relatively short and broad rostrum. As a member of Naupactini, it is part of a diverse tribe distributed primarily in the Neotropical region.
Phacepholis candidus
Phacepholis candidus is a species of broad-nosed weevil (Curculionidae: Entiminae) described by Horn in 1876. It belongs to the tribe Naupactini, a group of weevils predominantly distributed in the Neotropical region. The specific epithet "candidus" (Latin for "white" or "shining white") likely refers to a pale or whitish coloration of the integument. As with many Naupactini, detailed biological information remains limited in accessible literature.
Phacepholis elegans
Phacepholis elegans is a species of broad-nosed weevil in the family Curculionidae, described by Horn in 1876. It belongs to the tribe Naupactini, a group known for root-feeding larvae and adult weevils that typically feed on foliage. The species has been recorded from several western and midwestern U.S. states including Arizona, California, Colorado, Iowa, and Kansas. As with many Naupactini, the larvae likely feed on roots while adults feed on above-ground plant tissues.
Phacepholis obscurus
Phacepholis obscurus is a species of broad-nosed weevil in the family Curculionidae, described by Horn in 1876. It belongs to the tribe Naupactini within the subfamily Entiminae. The specific epithet 'obscurus' (Latin for dark or indistinct) likely refers to its coloration. As a member of Entiminae, it possesses the characteristic short, broad rostrum typical of this subfamily.
Phacepholis planitiatus
Phacepholis planitiatus is a species of broad-nosed weevil in the family Curculionidae, described by Buchanan in 1939. It belongs to the tribe Naupactini, a group of root-feeding weevils primarily found in the Americas. The species is documented from the Great Plains and Rocky Mountain regions of the United States. Like other Naupactini, adults likely feed on foliage while larvae develop in soil feeding on roots.
Phacepholis viridis
Phacepholis viridis is a species of broad-nosed weevil (Curculionidae: Entiminae: Naupactini) described by Champion in 1911. It belongs to a genus of Neotropical weevils in the tribe Naupactini, a group known for parthenogenetic reproduction and association with various host plants. The specific epithet 'viridis' (Latin for green) suggests a green coloration, though detailed species-level descriptions are limited in available sources. The genus Phacepholis is taxonomically classified within the subfamily Entiminae, a diverse group of weevils characterized by their broad snouts and often root-feeding larvae.
Platyomus
broad-nosed weevils
Platyomus is a genus of broad-nosed weevils in the family Curculionidae, first described by Sahlberg in 1823. The genus contains at least 40 described species and belongs to the tribe Naupactini within the subfamily Entiminae. These weevils are distributed in parts of South America, with records from Colombia and Peru.
Platyomus flexicaulis
Broad-nosed Ebony Weevil
Platyomus flexicaulis is a species of broad-nosed weevil in the family Curculionidae, subfamily Entiminae. The species was described by Schaffer in 1905. It belongs to the tribe Naupactini, a group of primarily New World weevils. Available records indicate it occurs in Texas, though detailed biological information remains sparse.
