Platycentrus
Platycentrus is a genus of treehoppers in the family Membracidae, subfamily Centrotinae, and tribe Platycentrini. The genus was established by Stål in 1869 and contains at least three described species: P. acuticornis, P. obtusicornis, and P. brevicornis. These species have been recorded from Mexico and the southwestern United States (California). As members of the primitive subfamily Centrotinae, they are characterized by an exposed scutellum, unlike most other membracid subfamilies where the pronotum covers this structure.
Tylocentrus quadricornis
Tylocentrus quadricornis is a treehopper species in the family Membracidae, subfamily Centrotinae, described by Funkhouser in 1919. It belongs to the tribe Platycentrini, characterized by exposed scutella and relatively unmodified pronota compared to other membracid subfamilies. The species is distributed across the southwestern United States and northwestern Mexico. Like other members of its genus, it exhibits the primitive centrotine body plan with reduced pronotal ornamentation.
