Anomalini
shining leaf chafers
Anomalini is a large and diverse tribe of scarab beetles within the subfamily Rutelinae, commonly known as shining leaf chafers. The tribe comprises approximately 1,300 described species worldwide, with significant representation across multiple biogeographical regions including the Palaearctic, Oriental, Ethiopian, Nearctic, and Neotropical regions. The tribe includes economically important pest species, particularly in agricultural settings, as well as numerous endemic taxa with restricted distributions. Members of Anomalini exhibit considerable morphological diversity, with diagnostic characters often concentrated in male genitalia structure and body sculpturing patterns.
Schizoptera
minute litter bugs
Schizoptera is the largest genus of minute litter bugs (Hemiptera: Heteroptera: Dipsocoromorpha), comprising approximately 90 described extant species plus two fossil species. The genus is divided into four subgenera: Schizoptera (Cantharocoris), Schizoptera (Odontorhagus), Schizoptera (Schizoptera), and Schizoptera (Zygophleps). Species are abundant in New World bulk and residue samples, with extensive undescribed diversity indicated by recent collecting efforts. Male genitalia are intricate and asymmetrical, providing excellent diagnostic features for species identification.
