Chionomus quadrispinosus
Chionomus quadrispinosus is a species of planthopper in the family Delphacidae, originally described by Muir and Giffard in 1924. As a member of the genus Chionomus, it belongs to a group of small delphacid planthoppers associated with grassland habitats. The species epithet 'quadrispinosus' refers to four spines, likely describing a diagnostic feature of the male genitalia or other sclerotized structures. Very few observations exist in public databases, suggesting it is either genuinely rare, cryptic, or underreported.
