Description: Holotype (male). Fastigium verticis with dorsal surface roundly declined; dorsal surface shallowly furrowed; not contacting fastigium frons. Pronotum with disc slightly rounded to nearly flat, but in posterior area slightly raised, lateral margins rounded into paranota; anterior margin concave in middle, posterior margin slightly rounded to transverse in middle; transverse sulcus circa triangular, slightly behind middle of pronotum; paranota longer than high, anterior angle angularly rounded, posterior angle broadly rounded, ventral margin obliquely straight, humeral sinus weak but distinct. Tegmen surpassing hind knees; hind wing longer than tegmen; radius sector branching in circa basal 1/3 part of tegmen, and emitting out 4 parallel branches behind middle; R also with another stem. Fore coxae unarmed. Fore femur with 7 interior ventral spines; mid femur with 10 exterior ventral spines; hind femur without ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 1 exterior dorsal spine over tympana; mid tibiae with 6 interior dorsal spines; hind tibiae with 31 large interior and 29 exterior dorsal spines, as well as with 1–2 small spines between two large exterior spines near apex.
Male stridulatory file with circa 45 large in basal 4/5 and 16 small teeth in distal 1/5 part, which are gradually becoming larger mediad (Plate 24d). Tenth abdominal tergum with apical margin slightly convex in middle (Plate 22e, 24e). Epiproct 1.5 times longer than wide; basal margin widest, suddenly narrowed and then weakly widened from middle part; apical margin approximately rounded and slightly convex into a rounded median lobe (Plate 22f, 24e). Cerci long, extending far beyond apex of subgenital plate; basal part cylindrical and slightly curved ventrad, distal part gradually acuminated and slightly curved dorso-mediad; apex forming a curved spine (Plate 22e, 24e–g). Subgenital plate with basal margin widest, then gradually narrowed to middle part and lateral margins subparallel in distal part; in dorsal view the plate concave entad from the sides; in lateral view the plate subflat in basal 3/5 part, and gradually bent up in distal 2/5 part; ventral surface distinctly with a median carina in basal half part; apical 2/5 part incised, close lateral lobes with obtuse apical margin (Plate 22g, 24g). Phallus with a pair of sclerites, which having lateral margins gradually narrowed, and apical margin denticulate.
PLATE 24, Color photograph of Elimaea jianfenglingensis sp. nov. (a–g), and Orthelimaea trapezialis sp. nov. (h–o). a,h, lateral lobe of pronotum of male, lateral view; b, i, male left stridulatory area, dorsal view; c, j, male right stridulatory area, dorsal view; d, male stridulatory file on underside of left tegmen; e, k, male abdominal apex, dorsal view; f, l, male abdominal apex, lateral view; g, m, male subgenital plate, apico-ventral view; n, male subgenital plate, ventral view; o, male cerci, dorsal view.
Female. Tenth abdominal tergum sinuate. Epiproct much longer than wide, triangular, with angular apex. Cerci slender, long, regularly curved and gradually narrowed to subobtuse apex (Plate 22h). Subgenital plate slightly wider than long, with a distinct median carina; apico-lateral angles acute-triangular projecting and with subobtuse apex; central part of apical margin truncated to slightly convex (Plate 22i). Ovipositor falcate, dorsal margin with apical 2/3 part crenulated and ventral margin only with apical quarter part denticulate (Plate 22h). Gonangulum of ovipositor with a short, obtuse, ventral projection (Plate 22j).
Color: Body yellowish green. Compound eyes brown. Pronotum, cells of tegmen except those in costal area, exposed part of hind wing and abdomen with numerous reddish brown dots. Pronotal carinae dark brown. Each of frontal corner of tegminal stridulatory area with a dark brown stripe. Apex of cerci brown.
Measurement (mm): length of body: male 18.0–19.0, female 27.0; length of pronotum: male 4.2–4.5, female 4.5; length of tegmen: male 32.5–33.0, female 35.5; largest width of male stridulatory area 2.0; length of male stridulatory vein 1.8; largest width of dorsal area behind male stridulatory area 1.2; width of mirror on right tegmen 1.0; length of mirror on right tegmen 1.0; distance between basal vein of right tegmen and apex of mirror on right tegmen 1.2; width of tegmen: male 4.5, female 5.5; length of hind wing: male 37.0, female 40.5; length of fore femur: male 8.5–9.0, female 11.0; length of mid femur: male 13.0, female 17.0; length of hind femur: male 24.5– 26.0, female 24.5; length of epiproct: male 2.0, female 1.5; length of cerci: male 4.0, female 2.5; length of subgenital plate: male 4.5, female 1.0; length of ovipositor 6.5.
Etymology: The name refers to the type locality of this new species.
Discussion: The species most similar to E. semicirculata Kang & Yang and E. parva Liu in the shape of male cerci and male subgenital plate, but different from those in the structure of epiproct, apical part of subgenital plate of both sexes, male stridulatory vein and apex of male cerci, and also different from E. parva in the size larger.
Distribution: China: Hainan Island.
