Xu, Ye, Lu, Sihan, Dietrich, Christopher H. & Qin, Daozheng, 2018, Descriptions of two new leafhopper species of the genus Flaviata Lu & Qin (Hemiptera, Cicadellidae, Typhlocybinae) from Southern China, with a key to known species, Zootaxa 4457 (4), pp. 577-582 : 581-582

Flaviata sinuata Xu, Dietrich & Qin , sp. n.

( Figs 19–34 )

Type materials. Holotype. Male, China, Guizhou, Maolan , 26 June 2017, coll. Wenhui Zhao ( NWAFU).

Paratypes. 16 males, 10 females, China, Guizhou, Maolan , 23–26 June 2017, coll. Wenhui Zhao ( NWAFU) ; 4 males, same data ( INHS) .

Description. Length, male 5.4–5.8 mm; female 5.4–6.0 mm.

Color. General body color dark yellow. Crown with a pair of irregular whitish spots on each side of coronal suture, coronal suture pale orange ( Figs 19, 21 ). Eyes black ( Figs 19–22 ). Ocelli whitish ( Figs 19–22 ). Face ginger yellow ( Fig. 22 ). Pronotum dark yellow centrally, anterior margin and arcuate area behind eyes with small irregular pale patches ( Figs 19, 21 ). Mesonotum with latero-basal angles and apex of scutellum yellow, centrally with sordid yellowish stripe ( Figs 19, 21 ). Fore- and hindwing subhyaline ( Figs 19, 20 ). Abdomen black dorsally ( Fig. 19 ). Legs yellow ( Figs 20, 22 ).

Male basal abdominal apoedmes attaining end of segment VI ( Fig. 25 ). Male pygofer in lateral view with 20–24 rigid microsetae along posterior margin, strongly sclerotized dorsally, terminal process extended beyond pygofer lobe and slightly sinuate ( Figs 23 , 26, 27 ), dorsal bridge slightly sclerotized, occupying 1/3–1/4 total length of the lobe, apically membranous ( Figs 24 , 28 ). Subgenital plate broad at base, B-group setae (27–29) arranged in 1–2 rows occupying nearly half length of dorsal margin, C-group setae (17–18) uniseraite from base to apex of plate, D-group setae numerous, long, starting near the base and reaching the apex of plate, arranged in 2–4 rows ( Figs 23 , 26, 32 ). Paramere sinuate, apically strong curved ventrad, apex acuminate, bearing 4 setae arranged in 2 rows and few sensory pits ( Figs 23 , 26, 33 ). Aedeagal shaft strongly swollen at base, apical half strongly narrowed, gonopore apical ( Figs 29, 30 ). Connective nearly trapezoidal, longer than wide, anterior margin with trapezoidal emargination, caudal margin with broad V-shaped notch ( Fig. 31 ). Anal tube appendage short, extended ventrad and strongly tapered in profile ( Figs 23 , 26, 34 ).

Etymology: The name is derived from the Latin word “ sinuatus ”, which refers to the shape of the paremere.

Diagnosis. This species is similar to F. variata and F. furcata sp. n. but differs from them in having the aedeagal shaft strongly swollen at base ( Fig. 29 ) and the anal tube appendage extended ventrad in profile ( Fig. 34 ).

Distribution. Southern China (Yunnan)
