Horn-1873
Guides
Acanthoscelides pectoralis
Acanthoscelides pectoralis is a small leaf beetle in the family Chrysomelidae, specifically placed in the subfamily Bruchinae (seed beetles). The species was described by Horn in 1873 and has a documented distribution spanning Central America and North America. Like other members of its genus, it is likely associated with leguminous host plants, though specific host records for this species remain limited in the available literature. The genus Acanthoscelides contains numerous species that are economically significant as pests of stored legumes and agricultural crops.
Ametor scabrosus
Ametor scabrosus is a water scavenger beetle (family Hydrophilidae) found across northern and western North America, with additional records from East Asia including China, Korea, and the Russian Far East. The species was described by Horn in 1873. Like other members of the genus Ametor, it inhabits aquatic environments where it contributes to decomposition processes.
Berosus rugulosus
Berosus rugulosus is a species of water scavenger beetle in the family Hydrophilidae. It is found in arid and semi-arid regions of the southwestern United States and Mexico. Like other members of the genus Berosus, it is associated with aquatic or semi-aquatic habitats. The species was described by George Henry Horn in 1873.
Carcinops tejonicus
Carcinops tejonicus is a hister beetle in the family Histeridae. The species is distributed in California, USA and Mexico. It has been recorded as present in both Middle America and North America.
Chalcodermus inaequicollis
Chalcodermus inaequicollis is a species of true weevil in the beetle family Curculionidae, described by Horn in 1873. It is found in North America. Like other members of the genus Chalcodermus, it is characterized by a distinctive body form and rostrum structure typical of the group.
Dryotribus
Dryotribus is a genus of weevils in the family Curculionidae, established by George Henry Horn in 1873. The genus contains four described species: D. amplioculus, D. mimeticus, D. solitarius, and D. wilderi. These beetles belong to the diverse beetle superfamily Curculionoidea, which is characterized by the distinctive elongated snout or rostrum typical of weevils. The genus is relatively poorly documented in scientific literature, with limited published information on its biology and ecology.
Hister lucanus
clown beetle
Hister lucanus is a species of clown beetle in the family Histeridae, described by Horn in 1873. It is distributed across parts of North America and Central America. Like other members of its family, it possesses the characteristic flattened legs that give clown beetles their common name.
Rhyssomatus aequalis
Rhyssomatus aequalis is a species of true weevil in the family Curculionidae, first described by George Henry Horn in 1873. It is native to North America with confirmed records from Canada (Ontario and Québec) and the United States. As a member of the hyperdiverse weevil family, this species exemplifies the remarkable diversity of the Curculionidae, which contains over 60,000 described species worldwide.
Rhyssomatus pubescens
Rhyssomatus pubescens is a species of true weevil in the family Curculionidae, found in North America. The species was described by Horn in 1873. It is one of approximately 11 species in the genus Rhyssomatus, a group of small weevils whose biology and host associations remain poorly documented for most species. Unlike the congener R. nigerrimus, which is a significant soybean pest in Mexico, or R. subtilis, which damages soybean pods in Argentina, the specific biology and economic importance of R. pubescens has not been established.
