However, it can be distinguished from the latter by the following features: (1) median and submedian carinae of vertex (Figs 1 C, 2 A, 3 C, 4 A, 5 C, 6 A) absent (median carina of vertex (Bartlett 2009: fig. 3) present, forked near anterior margin of eyes, arms of fork diverging strongly to meet submedian carinae in Procidelphax); (2) frons (Figs 1 E, 2 B, 3 E, 4 B, 5 E, 6 B) with median carina weak or absent, not forked (frons (Bartlett 2009: figs 5 B, 6 B) with median carina conspicuous, divided at lower level of eyes in Procidelphax); (3) genital styles (Figs 2 H, 2 I, 4 H, 4 I, 6 H, 6 I) forked apically (genital styles (Bartlett 2009: figs 5 f, 6 f) not forked apically in Procidelphax).	en	Li, Hong-Xing, Chen, Xiang-Sheng, Yang, Lin (2023): A new bamboo-feeding planthopper genus Aodingus Chen & Li (Hemiptera: Fulgoroidea: Delphacidae: Tropidocephalini) with descriptions of three new species from China and Vietnam.

Frons (Fig. 6 B) longer in middle line than wide at widest part about 1.90: 1.79, widest at middle level of eyes, median carina distinctly convex, lateral parts flat concave. Antennae (Fig. 6 B) with first segment shorter than second segment about 0.50: 1. Pronotum (Fig. 6 A) longer than vertex about 1.08: 1. Mesonotum (Fig. 6 A) longer than pronotum and vertex combined about 1.36: 1. Forewing (Fig. 6 C) longer in middle line than wide at widest part about 2.63: 1. MALE GENITALIA. Anal segment of male (Fig. 6 D) short, ring-like. Pygofer in posterior view (Fig. 6 D) with opening slightly wider than long, ventral margin concave U-shaped, with 2 small lobe-shape processes on both sides of medioventral margin, in lateral view (Fig. 6 E) ventral margin longer than dorsal margin, posterior margin sinuate. Aedeagus (Fig. 6 F) with phyllobase, phallus tubular, long, blunt rounded end, curved ventrally medially, with small process on ventral margin of aedeagus medially, phyllobase long, spinous, arising from base of aedeagus dorsally. Genital styles (Fig. 6 H – I) stout, long, attaining ventral margin of anal segment, apex forked, with large verruciform process at apical ¼.	en	Li, Hong-Xing, Chen, Xiang-Sheng, Yang, Lin (2023): A new bamboo-feeding planthopper genus Aodingus Chen & Li (Hemiptera: Fulgoroidea: Delphacidae: Tropidocephalini) with descriptions of three new species from China and Vietnam.
