Neurotettix spinas View in CoL sp. nov.

Figs 1–17 View FIGURES 1–12 View FIGURES 13–17 .

Measurements. Body length (including forewing): male 5.1-5.2 mm; female 5.3-5.4 mm; forewing length: male 4.3-4.4 mm; female 4.5-4.6 mm.

Coloration. Body yellow-brown, vertex with black spots along anterior margin, and with two irregular orange markings behind the spots ( Figs 1–2 View FIGURES 1–12 ). Eyes yellowish brown, ocelli white ( Figs 3–4 View FIGURES 1–12 ). Face brown, black transverse streaks and a yellow longitudinal band. Antennae pale yellowish white. Anteclypeus yellowish brown with apex dark-brown ( Figs 3, 5 View FIGURES 1–12 ). Pronotum brownish yellow, with 6 yellowish brown longitudinal markings ( Fig. 4 View FIGURES 1–12 ). Scutellum yellowish brown, basal and lateral angles pale brown ( Fig. 4 View FIGURES 1–12 ). Forewings yellowish-brown, with irregular fuscous markings, viens yellowish-white, apical part of forewings pale brown ( Figs 1–2 View FIGURES 1–12 ). Legs with dark spots ( Fig. 2 View FIGURES 1–12 ). Female abdominal genital segment pale yellowish white ( Fig. 13 View FIGURES 13–17 ).

Head and thorax. External features as in generic description. Crown shorter medially than width between eyes (0.54:1) ( Figs 1–4 View FIGURES 1–12 ). Pronotum longer medially than crown (1.56:1) ( Fig. 4 View FIGURES 1–12 ). Scutellum shorter medially than pronotum (0.82:1) ( Fig. 4 View FIGURES 1–12 ). Forewing longer than width at widest part (3.17:1) ( Figs 1–2 View FIGURES 1–12 ).

Male genitalia. Male pygofer broad triangular in lateral view, apex tapered, with three stout setae along dorsocaudal margin, ventro-posterior margin with short appendage curved upward ( Fig. 6 View FIGURES 1–12 ). Valve triangular ( Fig. 7 View FIGURES 1–12 ). Subgenital plate short and broad, lateral and apical margins convex except for slight preapical lateral concavity, with row of macrosetae extended obliquely from lateral to mesal margin near midlength ( Fig. 8 View FIGURES 1–12 ). Aedeagus asymmetric and twisted in ventral view, base robust, shaft medially on dorsal side with a short spine, apex curved to the left, gonopore subapical ( Figs 9–10 View FIGURES 1–12 ). Connective nearly X-shaped, arms longer than stem ( Fig. 11 View FIGURES 1–12 ). Style elongate, base broad, with apex of apophysis curved, tapering apically, fine setae at the curvature ( Fig. 12 View FIGURES 1–12 ).

Female genitalia. Female seventh sternum with posterior margin broadly transverse between pair of short, rounded lateral lobes. First valvula curved, tapering apically with concatenate sculpture extended to dorsal margin ( Figs 14–15 View FIGURES 13–17 ). Second valvula moderately slender through most of length, gradually tapered distally, dorsal margin with approximately 19 short, simple, acute teeth more or less evenly spaced over distal half, with hyaline region extended obliquely across middle and along ventral margin to distal fourth ( Figs 16–17 View FIGURES 13–17 ).

Type material. Holotype: ³, China: Guizhou Province, Xishui County, Dongfeng Lake Nature Reserve (28°32´N, 106°23´E, 1204 m), 16. XIII. 2019, Hong-Xing Li, Nian Gong, Qiang Luo & Sha-Sha Lv GoogleMaps . Paratypes: 4³³ 3♀♀, same as holotype ( GUGC) .

Host plant. Bamboo, Chimonobambusa angustifolia Chu & Chao ( Figs 18–20 View FIGURES 18–20 ).

Remarks. This new species is similar to Neurotettix truncatus Dai, Xing & Li, 2011 , but can be distinguished from the latter by the asymmetrical aedeagus with a short median dorsal spine, the male pygofer with a short appendage, and the strongly convex apical margin of the subgenital plate.

Etymology. The name is derived from the Latin word “ spinas ”, referring to the median spine on the aedeagal shaft.
