In P. bicornatus, the style inner process forming distinct hook with acute apex, while the outer process is moderately broader than inner one. Additionally, the subgenital plate is relatively longer and tapered towards apex.	en	Hussain, Riaz, Duan, Keting, Xing, Jichun (2026): Taxonomic notes on Pachymetopius Matsumura (Cicadellidae: Deltocephalinae: Stegelytrini) with description of three new species.
