Neurotettix horishanus Matsumura, 1914

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.

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.

Oriental Region and Palaearctic Region.

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.

Body yellow-brown, vertex with black spots along anterior margin, and with two irregular orange markings behind the spots, eyes dark-brown (Fig. 16). Face brown, transverse streaks and a longitudinal band yellow, anteclypeus yellow with apex dark-brown (Fig.18). Pronotum and scutellum yellowish-brown.

External features as in generic description.

Male genitalia. Pygofer side short, with eleven stout setae along dorso-caudal margin, its ventro-posterior margin with a long appendage (Fig. 7). Valve triangle (Fig. 8). Subgenital plate short and broad, with many setae in lateral margin, distally truncate, with 2 to 3 irregular rows of setae from lateral margin to middle of subgenital plate (Fig. 9). Aedeagus symmetrical, base robust, aedeagal shaft slender without processes, gonopore apical (Figs 10, 11). Connective nearly X-shaped, its arms longer than stem (Fig. 12). Style slender, elongate, with apex of apophysis curved laterally (Fig. 13).

Bamboo.

This species is similar to Neurotettix horishanus Matsumura, but can be distinguished from the latter by the symmetrical aedeagus and gonopore at apex, subgenital plate distally truncate and style apex curved.

The new species name is derived from the Latin words “truncatus”, indicating that the subgenital plate distally truncate.
