Distribution. China (Hainan); India; Burma; Nepal; Philippines; West Malaysia; Brunei (Dai et al., 2009).

Scaphomonus longistylus (Li & Wang, 2005)

Scaphotettix longistylus Li & Wang, 2005: 190.

Scaphomonus longistylus (Li & Wang), n. comb. by Dai et al., 2009: 661, Fig.7 A–H; Li et al.,2011: 262.

Note. The original name of this species refers to the very long subgenital plate, but mistakenly “ longistylus ” was written; in fact the style is not long.

Scaphomonus widestyleus Li, 2011 Figs 8–14 , 24–25

Scaphomonus widestyleus Li (in Li et al.),2011: 263–264.

Material examined. China: 13 (Holotype), Fujian Prov., Mt. Wuyi, Guadun, 9 September 1978, coll. Zhonglin Ge; 13, Guangxi Autonomous Region, Shangsi County, Shiwandashan, 12 May 2009, coll. Yanli Zheng (GUGC). Distribution. China (Fujian, Guangxi).

Note: The original figures of Li (in Li et al.,2011) lack a view of the aedeagus in lateral view. Here, the first author has redrawn the male genitalia.

Scaphomonus furcatus sp. nov. Figs 15–21 , 26–27

Description. Body ochraceous. Head with piceous submargial band on anterior margin, one transverse arcuate band between eyes anteriorly, narrowly margined with piceous, orange red ( Fig. 26 ). Face with thin, arcuate, piceous submarginal band. Pronotum with anterior brown and posterior submarginal chocolate brown transverse bands ( Fig. 26 ). Forewing ochraceous, with hyaline spots; piceous areas as shown in Figs. 26–27 .

Vertex shorter than pronotum, shorter medially than next to eye. Pronotum longer than scutellum( Fig. 26 ). External features as in generic description.

Male genitalia. Pygofer with a process on caudal margin and three spinose processes on ventrolateral margin ( Fig.15 ). Valve large, subtriangular ( Fig.16 ). Subgenital plate very long and narrow, with a row of stout setae along lateral margin and additional hair-like setae at apex ( Fig.17 ). Aedeagal shaft slender, longer than 2.5 times length of connective, apex forked, gonopore subapical on dorsal surface (Figs.18,19). Connective Y-shaped, articulated with aedeagus, its stem nearly 1/3 length of arms ( Fig.20 ). Style with prominent subapical lobe, apophysis slender and elongate ( Fig.21 ).

Measurement. Length (including tegmen): 3,4.9–5.0mm.

Type material. Holotype 3, China: Guangxi Autonomous Region, Jingxi County, Diding, 8 August 2010, coll. Shanyi Zhou; Paratypes: 13, Yunnan Prov., Xishuangbanna, Menglun, 28 July 2012, coll. Weibin Zheng (GUGC).

Diagnosis. This species is similar to Scaphomonus longistylus (Li & Wang), but can be distinguished from the latter by the male pygofer with caudal process, aedeagal shaft forked at apex, and the apophysis of style very elongate.

Etymology. The species name is derived from the Latin words “ furcatus ”, referring to the apical fork of the aedeagus.
