Lixinae
Guides
Cleonini
Cleonini is a tribe of weevils within the subfamily Lixinae, comprising approximately 96 extant genus-group taxa distributed globally. All extant members are hypothesized to be flightless despite frequently possessing fully developed wings (macropterous), a unique condition among Lixinae. The tribe exhibits widespread adult morphological homoplasy that obscures phylogenetic relationships, with many genera radiating from a common ancestor with weakly resolved internal branching. Cleonini are primarily associated with arid and semi-arid habitats, including deserts and steppe environments across North Africa, the Middle East, Central Asia, and western North America.
Rhinocyllini
Rhinocyllini is a tribe of weevils within the subfamily Lixinae, characterized by their association with thistles (Asteraceae: Cardueae). Members are recognized by their distinctive rostrum structure and have been studied for their potential as biological control agents against invasive thistle species. The tribe includes economically significant genera such as Rhinocyllus, which has been introduced to multiple countries to manage thistle populations.
Scaphomorphus boucardi
Scaphomorphus boucardi is a species of weevil in the family Curculionidae. The genus Scaphomorphus belongs to the weevil subfamily Lixinae. This species is part of a genus of elongate, cylindrical weevils found in the Americas. Very little specific information is available about this particular species in published literature.
Scaphomorphus calandroides
Scaphomorphus calandroides is a weevil species in the family Curculionidae, subfamily Lixinae. The species was originally described as Lixus calandroides by Randall in 1838 and later transferred to the genus Scaphomorphus. It is a North American species with limited documented occurrence records. As a member of the Lixinae, it belongs to a group of weevils commonly known as 'lixine weevils,' which are typically associated with herbaceous plants. The genus Scaphomorphus contains species with somewhat cylindrical body forms and elongated rostra.
Scaphomorphus collaris
Scaphomorphus collaris is a species of weevil in the family Curculionidae, subfamily Lixinae. The genus Scaphomorphus comprises lixine weevils, with several species exhibiting endemic distributions in Florida. Members of this genus are associated with specific host plants, including lupines.
Scaphomorphus erysimi
Scaphomorphus erysimi is a species of weevil in the family Curculionidae, subfamily Lixinae. The species was originally described by Fall in 1901 under the genus Cleonus and later transferred to Scaphomorphus. It is currently recognized as a synonym of Cleonus erysimi in some taxonomic databases, though iNaturalist maintains it under Scaphomorphus. Very little is known about this species' biology or distribution beyond basic taxonomic records.
Scaphomorphus longinasus
Scaphomorphus longinasus is a species of weevil in the family Curculionidae, subfamily Lixinae, originally described by Anderson in 1987 under the genus Cleonidius. It is a North American species with limited available information on its biology and ecology. The genus Scaphomorphus contains species associated with various host plants, though specific details for S. longinasus remain sparse. Based on GBIF records, the species has been documented as present in North America.
Scaphomorphus pleuralis
Scaphomorphus pleuralis is a species of weevil in the family Curculionidae, genus Scaphomorphus. The genus Scaphomorphus is a group of lixine weevils (subfamily Lixinae) distributed in the Americas. The species epithet 'pleuralis' refers to lateral (pleural) features, likely describing some aspect of the thoracic structure. Very few documented observations of this species exist, with only a single observation recorded on iNaturalist, indicating it is either rare, cryptic, or under-collected. The genus is related to Scaphomorphus subcylindricus, a Florida endemic found on Lupinus ocalensis (Ocala lupine).
Scaphomorphus puberulus
Scaphomorphus puberulus is a species of weevil in the family Curculionidae, described by LeConte in 1876. It belongs to the genus Scaphomorphus, a group of lixine weevils found in North America. The species is documented from the Canadian provinces of Alberta and Manitoba, though specific details about its biology, host associations, and ecology remain poorly known in published literature.
Scaphomorphus subcylindricus
Scaphomorphus subcylindricus is a species of weevil in the family Curculionidae. It is endemic to Florida, where it has been collected in dry oak/pine sandhill woodland habitats. The species is associated with the endemic plant Lupinis ocalensis (Ocala lupine), on whose foliage it has been observed. The species was documented during field surveys in the Citrus Wildlife Management Area of Withlacoochee State Forest.
