Peng, Ling-Fei, Fletcher, Murray J. & Zhang, Ya-Lin, 2012, Review of the Oriental planthopper genus Flata Fabricius (Hemiptera: Fulgoroidea: Flatidae) with the description of five new species, Zootaxa 3399, pp. 1-22 : 7-9

4. Flata orientala sp. nov.

( Figs. 3 , 4 )

Color. Body and tegmina stramineous and slightly greenish; eyes brown; tegmina with many small black spots ( Fig. 3 ).

Morphology. Body length: 16 mm.

Head: Vertex 5.5 times wider than long; frons almost as wide as long; frontoclypeal suture shallowly convex; rostrum extending to meso-trochanter.

Thorax: Pronotum anterior margin convex; lateral margins extending lateroventrally; postocular eminence ridged. Mesonotum posterior angle about 85°. Metatibia with seven spines apically and basal segment of metatarsi with nine spines apically. Tegmina with costal margin slightly convex at base; apical margin elongate convex; sutural margin truncate; apical angle rounded; sutural angle about 105°; vein Cu once forked, the branches joining postclaval margin ( Fig. 3 C).

Male genitalia: Pygofer quadrangular, anterior margin S-shaped ( Fig. 4 C). Genital style slightly hemispherical with a short process at dorsal apex; ventral margin rounded ( Fig. 4 C). Anal tube in lateral view large and long, widest at subapical portion, bent down at midlength ( Fig. 4 C). Phallobase tubular at base; dorsolateral lobe slender, each side of apex with two processes, inner one small, finger-like; outer one long and directed cephalad; lateral emargination deeply concave ( Figs. 4 D, G); ventral lobe long, with many spine-like processes ( Figs. 4 D, E). Theca with one long process at apical third on each lateral side; apex bipartite, each side with two processes, anterior one as long as phallus and heavily branched, posterior one simple and circled in dorsal view ( Figs. 4 D, F).

Type material. Holotype, 3, Mt. Wuyanling, Zhejiang Province, China, 20.vii.1983, Zhen Bin ( NWAFU); paratypes, CHINA, Guangdong Province: 13, Mt. Dadongshan, Lian county, 0 6. vii.1997, Xie Weicai ( SYSU); 13, Mt. Dadongshan, Lian county, 0 6. vii.1997, Su Guanhua ( SYSU).

Etymology. The specific name, which is masculine, is derived from the English word “oriental”.

Distribution. China (Guangdong, Zhejiang).

Remarks. This new species differs from other similar species of the genus by the male theca bearing a long lobe-like process medially and the apical margin of the tegmen being convex.
