Chrysobothris acutipennis
Chrysobothris acutipennis is a metallic wood-boring beetle in the family Buprestidae. It has been documented across Central America, North America, and South America, with confirmed records from Mexico to South America. The species has been taxonomically confused with similar Chrysobothris species, particularly C. fallax from northwestern Peru, from which it can be distinguished by the form of the tooth on the profemora and male genitalia. A 2022 revision clarified its distribution and distinguished it from C. merkelii.
Griburius
case-bearing leaf beetles
Griburius is a genus of case-bearing leaf beetles in the family Chrysomelidae, subfamily Cryptocephalinae. The genus contains approximately six described species in the United States, with additional species distributed throughout the Neotropical Region. A 2022 taxonomic revision revised nine species in the G. posticatus species group, transferred one species from Metallactus, proposed multiple synonymies, and described two new Brazilian species. Members of this genus are characterized by their case-bearing habit, where larvae construct protective cases from fecal material and shed skins.
Pristepyris
Pristepyris is a genus of small parasitoid wasps in the family Bethylidae, comprising 38 described species distributed across the Old World and New World except the Australian Region. Members of this genus are ectoparasites of click beetle larvae (Elateridae). The genus has been subject to recent taxonomic revision, particularly for Taiwanese and Ryukyuan species.
Syzeton
ant-like leaf beetles
Syzeton is a genus of ant-like leaf beetles in the family Aderidae, containing more than 10 described species distributed in North America. The genus was resurrected and redefined in 2022 when species formerly placed in Zonantes were transferred to Syzeton based on phylogenetic research. Members of this genus exhibit the characteristic ant-mimicking morphology typical of Aderidae, with compact bodies and often reduced elytra. The genus includes both historically described species and several newly described species from 2022.
Syzeton fasciatus
Syzeton fasciatus is a species of ant-like leaf beetle in the family Aderidae, native to North America. The species was transferred from the genus Zonantes to Syzeton in 2022 based on phylogenetic research. Members of Aderidae are characterized by their small size, elongated bodies, and ant-like appearance, though specific details for this species remain limited.
Syzeton signatus
Syzeton signatus is a species of ant-like leaf beetle in the family Aderidae. It was originally described in 1848 and formerly classified under the genus Zonantes. A 2022 taxonomic revision transferred the species to the genus Syzeton. It is known from North America.
