urn:lsid:zoobank.org:act:69EEC17D-7E23-4C70-82DB-C7FD18818521

Type species

Aodingus hainanensis gen. et sp. nov., here designated.

Diagnosis

Body strongly dorsoventrally flattened ( Figs 1B View Fig , 3B View Fig , 5B View Fig ). Head including eyes narrower than pronotum ( Figs 1C View Fig , 2A View Fig , 3C View Fig , 4A View Fig , 5C View Fig , 6A View Fig ). Vertex broad, apical margin rounded, median and submedian carinae absent ( Figs 1C View Fig , 2A View Fig , 3C View Fig , 4A View Fig , 5C View Fig , 6A View Fig ). 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 View Fig , 2B View Fig , 3E View Fig , 4B View Fig , 5E View Fig , 6B View Fig ). Pronotum about as long as vertex medially, lateral carinae straight, attaining hind margin. Mesonotum subequal to vertex and pronotum combined ( Figs 1C View Fig , 2A View Fig , 3C View Fig , 4A View Fig , 5C View Fig , 6A View Fig ). Forewing long, apical margin rounded, with crossveins in apical third ( Figs 2C View Fig , 4C View Fig , 6C View Fig ). 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 View Fig , 3F View Fig , 5F View Fig ). Anal segment of male short, ring-like ( Figs 2D View Fig , 4D View Fig , 6D View Fig ). Pygofer in posterior view with opening slightly wider than long, lateral margins sinuate ( Figs 2D View Fig , 4D View Fig , 6D View Fig ). Aedeagus with phyllobase, phallus tubular, curved medially, phyllobase slender, arising from base of aedeagus dorsally ( Figs 2F View Fig , 4F View Fig , 6F View Fig ). Genital styles long, forked apically ( Figs 2H, 2I View Fig , 4H, 4I View Fig , 6H, 6I View Fig ).

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 View Fig , 3A–C View Fig , 5A–C View Fig ). However, it can be distinguished from the latter by the following features: (1) median and submedian carinae of vertex ( Figs 1C View Fig , 2A View Fig , 3C View Fig , 4A View Fig , 5C View Fig , 6A View Fig ) 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 View Fig , 2B View Fig , 3E View Fig , 4B View Fig , 5E View Fig , 6B View Fig ) 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 View Fig , 4H, 4I View Fig , 6H, 6I View Fig ) forked apically (genital styles ( Bartlett 2009: figs 5f, 6f) not forked apically in Procidelphax ).
