Malacopterus tenellus
Malacopterus tenellus is a species of longhorn beetle in the family Cerambycidae, first described by Johan Christian Fabricius in 1801. The species is distributed across parts of South America and the Caribbean, with records from Brazil, Bolivia, and other regions. As a member of the tribe Oemini within the subfamily Cerambycinae, it represents a lineage of wood-boring beetles. The original description placed it in the genus Callidium, but it was later transferred to Malacopterus.
Malobidion
Malobidion is a genus of longhorn beetles (Cerambycidae) described by Schaeffer in 1908. The genus contains three described species distributed in the southwestern United States and Mexico: M. auricome, M. brunneum, and M. grande. Members of this genus belong to the tribe Hesperophanini within the subfamily Cerambycinae. The genus is characterized by moderate body size and relatively sparse documentation in scientific literature.
Mannophorus forreri
Mannophorus forreri is a longhorn beetle in the family Cerambycidae, described by Henry Walter Bates in 1885. It belongs to the tribe Trachyderini, a group known for often brightly colored and patterned species. The species is rarely encountered in collections and appears to have a restricted distribution in the southwestern United States and Mexico. Field observations indicate adults are active in early autumn and visit flowers of yellow composites in mountainous areas of Arizona.
