Zhang, Zheng-Guang & Chen, Xiang-Sheng, 2012, A new genus of the tribe Parahiraciini (Hemiptera: Fulgoromorpha: Issidae) from China with the description of two new species, Zootaxa 3174, pp. 35-43 : 39-41

Neotetricodes kuankuoshuiensis Zhang & Chen , sp. nov.

( Figs 10–18 , 22–24 )

Description. Body length (from apex of vertex to tip of forewings) 3 6.70 mm (N = 1), Ƥ 7.70 mm (N = 1); forewings length 3 5.45 mm (N = 1), Ƥ 6.30 mm (N = 1).

General coloration. Vertex ( Figs 10 , 22 ) dark brown with pale brown marks, eyes brown. Frons ( Figs 11 , 24 ) brown with light brown verrucoses near lateral margins. Clypeus, antenna dark brown. Rostrum brown. Pro- and mesonotum dark brown with pale brown verrucoses. Forewings brown with black marks scattered, veins with more or less green. Hindwings dark brown. Legs brown with dark brown marks. Abdomen ventrally black brown.

Head and thorax. Vertex ( Figs 10 , 22 ) 2.0 times wider at base than long in midline. Frons ( Figs 11 , 24 ) 1.2 times longer in midline than the widest part. Pronotum 1.6 times longer than vertex in midline. Mesonotum 1.6 times longer than pronotum in midline. Forewings ( Figs 12 , 22 ) 2.6 times longer than widest part, longitudinal veins distinct, Sc and R convergent 1/3 near base, M four-branched, MA bifurcate at apical part, MP bifurcate at middle part, Cu simple. Hind tibiae with two lateral teeth near apex. Spinal formula of hind leg: 3 (N = 1) 8–10–2, Ƥ (N = 1) 8–10–2.

Male genitalia. Anal tube ( Fig. 15 ) in dorsal view oval. Anal style short and broad near apical part. Anal tube ventrally with a process in midline (in lateral view). Aedeagus ( Figs 16, 17 ) strongly curved in lateral view, with lateral, ventral and dorsal lobes, dorsal lobe of aedeagus distally with a triangular process in midline, each side with a small triangular process. Aedeagus laterally with two laminae near middle on each side, the distal laminae with gladiate processes directing caudad, lateral lobes apically bilobed, acute or rounded apically (in ventral view), anterior margin of ventral lobe trifoliate. Genital styles ( Fig. 18 ) in profile long oval, with strong process on dorsal margin, caudo-dorsal angle rounded.

Type material. Holotype 3, CHINA. Guizhou Province: Kuankuoshui National Natural Reserve (28°14’N, 107°13’E), 800–1400m, 9 June 2010, P. Zhang. Paratypes: 1 Ƥ, Guizhou Province: Chishui National Natural Reserve (28°34’N, 105°42’E), 315m, 28–29 May 2006, Z.-H. Zhou.

Etymology. The specific name refers to the locality, Kuankuoshui National Natural Reserve, Guizhou Province, China.

Remarks. This new species is similar to N. quadrilamina , but can be distinguished from the latter by: hind tibiae with two lateral teeth, spinal formula of hind leg (8–10–2); anal tube in dorsal view oval, ventrally with a process; the distal laminae of aedeagus with gladiate processes; the process of dorsal lobe laterally with a small triangular process on each side (in the latter hind tibiae with three lateral teeth, spinal formula of hind leg (8–8–2); anal tube in dorsal view subtriangular; the distal laminae of aedeagus without any process; the process of dorsal lobe without any process on each side).

Host plant. Unknown.

Distribution. Southwest China (Guizhou) ( Fig. 25 ).
