Zhang, Ya-Lin, Peng, Ling-Fei & Wang, Ying-Lun, 2010, Review of the planthopper genus Amasha Medler (Hemiptera: Fulgoromorpha: Flatidae: Phyllyphantini) with description of one new species from China, Zootaxa 2664, pp. 61-68 : 66-67

Amasha haina sp. nov.

( Figs. 15–22 )

Color. Body and tegmen light green, aged specimens ochreous or stramineous. Tibia and tarsus dark brown. Veins of tegmen ochreous and outlined. Eye dark brown.

Structure. Body length 10.90–13.10. Head including eyes narrower than pronotum; vertex wider (1.12) than long (0.45), anterior margin sinuately convex, dorsal median carina and U-shaped carina obvious, lateral margin slightly raised; transverse intergenal carina disappeared ( Figs. 15–16 ). Frontal disc flat, not convex, wider (1.50–1.56) at widest part than long (1.41–1.47) in middle line, lateral margin slightly elevated, with very short median and U-shaped carina at dorsal side, frontoclypeal suture shallowly convex, clypeus triangular, strongly convex ( Fig. 17 ); rostrum extended to meso-trochantes. Pronotum longer than vertex in midline. Mesonotum with three longitudinal carinae. Post-tibia with six spines apically, basal tarsal segment with seven or eight spines apically. Tegmen length 9.56–11.68, width between costal margin and apex of clavus 4.76–5.83, costal membrane as wide as costal cell; postclaval sutural margin extended from apex of clavus at angle of 170°, meeting apical margin at angle of 102°, with 14–17 apical cells ( Fig. 18 ); tegmen margin without red color; branch of vein M not merged with Cu1, one distinct subapical line ( Fig. 18 ).

Male genitalia. Pygofer ring-like, in lateral view with anterior margin strongly concave, posterior margin straight ( Fig. 19 ). Genital style triangle, with strong process at dorsocaudal portion ( Fig. 19 ). Anal segment lateral view slender, apical third 115° angulated ( Fig. 19 ), in dorsal view lateral margin slightly convex, apical margin concave medially ( Fig. 22 ). Phallus slightly arched; phallobase tubular, with line of tiny teeth from middle of dorsal margin to base of lateral lobe; dorsolateral emargination truncate in lateral view, with two processes, outer one strongly zigzag, inner one produced into simple long slender process, reaching base of phallobase; ventral lobe pointed at apex, ventral view triangular; ventralateral portion with a ridge without tooth; theca bipartite, apex of theca narrower than A. inepta , near dorsal apex with pair of short cephalad processes, sinuate and finger-like ( Figs. 20–21 ).

Type material: Holotype, 3: Jianfengling, Hainan Province, China, 950m, 20.vii.2009, Wang Manqiang & Meng Rui ( NWAFU); Paratypes, 13: Jianfengling, Hainan Province, China, 2.vi.1983, Gu Maocen ( CFRB); 1Ƥ: Jianfengling, Hainan Province, China, 5.viii.1982, Liang Chengfeng ( IZCAS); 1Ƥ: Jianfengling, Hainan Province, China, 21.vii.2009, Wang Manqiang & Meng Rui ( NWAFU).

Distribution: China (Hainan).

Etymology: The species name is derived from the type locality Hainan Province.

Remarks: This species resembles A. inepta Medler , but can be distinguished from the latter by its tegmen margin without red color; vertex transverse intergenal carina covered by pronotum; male phallobase with a process longer and simple, reaching base of phallobase, not branched; ventral part with a ridged margin, not toothed.
