Empoasca (Matsumurasca) clypeata , n. sp.

( Figs. 1–13 )

Type materials. Holotype, male ( NWAFU), Dahaoping, Tengchong, Yunnan Province, 26 Nov. 1999, 1950- 2000 m, coll. Irena Dworakowska. Paratypes, 1 ɗ, 25 Nov. 1999, 2000 m; 2ɗ, 26 Nov. 1999, 1950-2000 m, same data as holotype. 1ɗ, Taibao mountain, Yunnan Province, 20 Nov. 1999, 1900 m; 1ɗ, Dahaoping, Tengchong, Yunnan Province, 24 Nov. 1999, 2000 m; 1ɗ, Jindian, Kunming, Yunnan Province, 2 Jan. 2000, coll. Daozheng Qin ( NWAFU).

Length. Male 4.0–4.3mm.

Colour. Vertex yellow, with a grayish-green patch centrally on each side of coronal suture; ocelli surrounded by ivory patch; coronal suture beige. Eyes grayish-black. Frontoclypeal area and genae yellow; anteclypeus yellowish-green, apical half light blue green. Pronotum with lighter patches at anterior margin and arcuate area behind eyes; scutellum with quadrate creamy patch antero-mesally. Forewing and hind wing hyaline. Abdomen yellow. Legs yellow except 1st-2nd tibiae and tarsi and 3rd tarsi sordid blue green.

Abdominal apodemes parallel-sided, rather obliquely truncate apically, surpassing half of 5th segment. Male pygofer elongated, terminal part rather quadrangular in outline, 10–13 rigid setae on each side of pygofer lobe; ventral pygofer appendage bent dorsocaudad in basal third and exceeding caudal margin of pygofer lobe, adorned with numerous hair-like outgrowths in caudal third before tapering in apical 1/4 to a pointed apex. Subgenital plate with basal group of 2–3 long, thick setae, 13–17 short marginal microsetae, 17– 23 long lateral macrosetae and fine microsetae arranged in 2–3 irregular rows. Paramere broad in basal part, narrowing to short curved apical part, with 5 closely placed teeth preceeded by 2–3 setae. Aedeagal shaft very short, less than half length of preatrium, obliquely truncate apically, in caudal view aedeagus slightly expanded in apical third and narrowing basad, gonopore ventrad near apex. Connective broad, anterior margin thickened, caudal margin incised medially. Anal tube process very short, swollen at base and abruptly narrowing to pointed apex.

Female. Unknown.

Etymology. The species name is treated as a adjective and refers to the peculiar clypellus.

Discussion. Empoasca (Matsumurasca) clypeata n. sp. rsembles Empoasca (Matsumurasca) parvifacia Dworakowska, 1994 , but differs in being longer (4.0–4.3 mm compared to 3.7–4.0 mm in E. (M.) parvifacia ); the ventral pygofer appendage is apprently bent caudodorsad in basal third and adorned with tufted hairs in apical third and the anal tube process very short, swollen basally and abruptly narrowing to pointed apex.

Type materials. Holotype, male ( NWAFU), Shenlongjia, Hubei Province, 29 Jul. 2001, coll. Min Huang & Guilin Zhang. Paratypes, 1ɗ, the same data as holotype. 3ɗ, 25 Jul. 2001, other data as holotype. 1Ψ, 9 Aug. 2001, Hengshi, Tongshan County, Hubei Province, coll. Min Huang. 1ɗ, Tianping mountain, Sangzhi, Hunan Province, 14 Aug. 2001, coll. Qiang Sun, light trap. 2 ɗ, Sangzhi, Hunan Province, 3 Sept. 1981, coll. Xinwang Tong. 1 ɗ, Emei mountain, Sichuan Province, 30 Oct. 1999, 800 m, coll. Daozheng Qin ( NWAFU).

Length. Male 4.1–4.5 mm, Female 4.3 mm.

Colour. Vertex yellowish-green, area between ocelli somewhat sordid, with grayish-green patch on each side of vertex centrally and longitudinal creamy streak along coronal suture not reaching anterior margin, bordering eye with creamy patch basally at each side; ocelli surrounded by creamy patch mesocaudad; coronal suture beige. Eyes blackish-brown. Frontoclypeal area yellow, with small creamy patches in anteocular areas and at base centrally; anteclypeus yellowish, apical half light blue green; genae yellowish-green. Along anterior margin and arcuate area in anterior part of pronotum with 3 irregular creamy patches and a quadrate creamy patch in centre of scutellum anteriorly. Forewing and hind wing hyaline. Abdomen yellow. Legs sordid green, 3rd tibia and 3rd tarsus in basal half yellow.

Abdominal apodemes parallel-sided, reaching end of 4th segment. Male pygofer elongated, almost quadrangular, dorsal margin slightly sinuate, with 7–9 stout setae on each side of pygofer lobe; ventral pygofer appendage exceeding pygofer lobe, apical 1/6 curved and tapering to a pointed apex. Anterior margin of subgenital plate broad in apical 2/5, with 2–3 microsetae in basal group, 16–22 short marginal microsetae, 20–23 long lateral macrosetae and fine microsetae arranged in 2–3 irregular rows. Paramere solid, apex almost truncated, subapical region with 7 teeth preceeded by about 5–6 setae. Aedeagal shaft in lateral view nearly twice as long as preatrium, broad basally and narrowing distally, apical 1/3 continuously curved with apex pointed and directed ventrad, shaft with pair of flange-like processes, gonopore dorsad near apex. Connective with anterior margin thickened and caudal margin incised medially. Anal tube process long, lamellate in side view, broad at base, apical part sinuate and abruptly tapering to pointed apex.

Female. Body colour similar to male.

Etymology. The name of this species is treated as a adjective, refering to the two flange-like processes on the aedeagal shaft.

Discussion. Empoasca (Matsumurasca) biloba , n. sp. can be distinguished from other species of the subgenus by the subgenital plate being very broad basally and the aedeagal shaft dorsally armed with a pair of flange-like processes.
