Neurotettix Matsumura

Neurotettix Matsumura 1914: 192; Esaki and Ito 1954: 128; Ishihara 1963: 223.

Type species:

Neurotettix horishanus Matsumura, 1914

Description.

Medium sized leafhoppers, body elongate, vertex triangular and produced. Head including eyes clearly narrower than pronotum. Eyes black, large. Ocelli located on anterior margin of vertex, near eyes. Face with dark, transverse streaks. Frontoclypeus long and narrow. Pronotum longer than vertex, its length of lateral carina 1/3 basal width of eye, anterior margin roundly protruded and posterior margin concave. Scutellum triangular, slightly shorter than pronotum, with transverse suture curved and depressed. Forewings with four apical cells and three subapical cells, apical cells short, anteapical cells with reticulate veins, clavus irregularly reticulated with many extra veins, appendix small.

Male pygofer side with about 10 stout setae, its ventro-posterior margin with a long appendage. Valve triangular. Subgenital plate with many setae in lateral margin. Aedeagus asymmetrical or symmetrical, base robust, aedeagal shaft slender or robust, with or without processes, gonopore apical or subapical. Connective nearly X-shaped. Style slender, elongate.

Diagnosis.

Neurotettix may be distinguished from other Athysanini by the following combination of features: forewings with apical cells short, anteapical cells with reticulate veins, clavus irregularly reticulated with many extra veins; connective nearly X-shaped.

Distribution.

Oriental Region and Palaearctic Region.

Disscussion.

The aedeagus is asymmetrical in the type species in original description ( Ishihara 1963). But, the aedeagus is symmetrical in the other two species ( Neurotettix bifurcatus and Neurotettix flangenus ) and the new species Neurotettix truncatus sp. n. According to the external characters and other male genitalia features, we confirmed the other two species and the new species belong to the genus Neurotettix .
