Type species
Aodingus hainanensis gen. et sp. nov., here designated.
Diagnosis
Body strongly dorsoventrally flattened (Figs 1B, 3B, 5B). Head including eyes narrower than pronotum (Figs 1C, 2A, 3C, 4A, 5C, 6A). Vertex broad, apical margin rounded, median and submedian carinae absent (Figs 1C, 2A, 3C, 4A, 5C, 6A). Frons broad, wider at base than at apex, lateral margins convex outward distinctly, median carina weak or absent. Antennae cylindrical, exceeding level of frontoclypeal suture, first segment shorter than second segment (Figs 1E, 2B, 3E, 4B, 5E, 6B). Pronotum about as long as vertex medially, lateral carinae straight, attaining hind margin. Mesonotum subequal to vertex and pronotum combined (Figs 1C, 2A, 3C, 4A, 5C, 6A). Forewing long, apical margin rounded, with crossveins in apical third (Figs 2C, 4C, 6C). Spinal formula of hind tibia 5-6-4. Post-tibial spur large and thick, concave on inner surface, without teeth along hind margin, with an apical tooth (Figs 1F, 3F, 5F). Anal segment of male short, ring-like (Figs 2D, 4D, 6D). Pygofer in posterior view with opening slightly wider than long, lateral margins sinuate (Figs 2D, 4D, 6D). Aedeagus with phyllobase, phallus tubular, curved medially, phyllobase slender, arising from base of aedeagus dorsally (Figs 2F, 4F, 6F). Genital styles long, forked apically (Figs 2H, 2I, 4H, 4I, 6H, 6I).
Remarks
The new genus is similar to Procidelphax Bartlett, 2009 in having the body strongly dorsoventrally flattened, vertex rather quadrate, apical margin broadly rounded (Figs 1A–C, 3A–C, 5A–C). However, it can be distinguished from the latter by the following features: (1) median and submedian carinae of vertex (Figs 1C, 2A, 3C, 4A, 5C, 6A) 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 1E, 2B, 3E, 4B, 5E, 6B) with median carina weak or absent, not forked (frons (Bartlett 2009: figs 5B, 6B) with median carina conspicuous, divided at lower level of eyes in Procidelphax); (3) genital styles (Figs 2H, 2I, 4H, 4I, 6H, 6I) forked apically (genital styles (Bartlett 2009: figs 5f, 6f) not forked apically in Procidelphax).
Etymology
The name is derived from the transliteration of the Chinese ‘ aoding ’, meaning the middle part of vertex is concave. It is masculine in gender.
Host plant
Bambusoideae Luerss.
Distribution
China (Hainan, Yunnan), Vietnam (Thanh Hoa).
