Elimaea (Rhaebelimaea) curvicerciata Liu C-X & Liu X-W, sp. nov. (Plate 12d, 16f, 17j–o)

Holotype: male (No. 14520567), China: Guangxi Prov.: Jinxiu, Shengtangshan Mt., 1979m, 1981. X.14, Coll. Jin, Li ( MSIE).

Description: Holotype (male). Tegmen surpassing apex of hind femur; hind wings distinctly longer than tegmen; radius sector branching in basal 1/3 part of tegmen, and emitting out 4 parellel branches near apex. Fore coxae unarmed. Fore femur with 5 interior ventral spines; mid femur with 4–5 interior ventral spines; hind femur with 1 interior ventral spine. Genicular lobes of each femur bispinose. Fore tibiae with 4 interior dorsal spines; hind tibiae with 37 interior and 30 exterior large dorsal spines, with 0–5 small spines between two large spines, and number of the small spines between large spines increasing from base to apex.

Stridulatory file with circa 20 widely spaced large stridulatory teeth in basal 2/3 and numerous small teeth in distal 1/3 part, which are gradually becoming smaller distad (Plate 12d). Epiproct deflexed, obtuse triangular (Plate 16f). Cerci long, extending over apex of subgenital plate, oblique backwards, distinctly incurved, basal margin widest, and then gradually acuminated toward apex, distal half abruptly upcurved, even upright at distal 1/6 part, with a hook curved backwards at apex (Plate 16f, 17m –o). Subgenital plate long, curved backward in lateral view; basal margin widest, then abruptly narrowed to basal 1/3 part; triangularly excised at apical 1/10 part, into two divergent lateral lobes (Plate 16f, 17m,n). Phallus with a pair of conchate sclerites, which covered each other, internal margin with numerous small brown teeth.

Color: Body yellowish green (maybe green at live). Compound eyes light brown. Antennae with yellow scape and pedical, and approximately black exterior margin and brown interior margin of flagella. Surface and lateral margins of pronotal disc, and anterior margin of lateral lobes of pronotum densely covered with numerous black large and small dots. Lateral surface of hind femur densely covered with red brown dots. Tegminal costal area with many light brown spots of moderate size, each cell between R and M veins with a few brown spots, area near posterior margin with numerous dark brown dots. Proximal area in tegminal stridulatory area with a large black spot. Apical spine of cerci and tooth of phallus red brown.

Female unknown.

Measurement of male (mm): length of body 14.2; length of pronotum 4.5; width of pronotal disc at base 2.0; width of pronotal disc at apex 2.1; length of tegmen 31.0; largest width of male stridulatory area 2.3; length of male stridulatory vein 2.0; largest width of dorsal area behind male stridulatory area 2.0; width of mirror on right tegmen 1.5; length of mirror on right tegmen 1.6; distance between basal vein of right tegmen and apex of mirror on right tegmen 2.2; width of tegmen 5.5; length of hind wing 37.1; length of fore femur 8.0; length of fore tibiae 9.0; length of mid femur 11.1; length of mid tibiae 13.5; length of hind femur 23.5; length of hind tibiae 29.1; length of epiproct 1.1; length of cerci 4.2; length of subgenital plate 5.4.

Etymology: The name refers to the special male cerci, which is strongly curved, especially in distal half.

Discussion: This new species most resembles E. (Rhaebelimaea) hebardi Hebard, 1922 , in shape of the male cerci, but differs by shape of the male subgenital plate. It also differs from E. (Rhaebelimaea) curvicercata Brunner von Wattenwyl, 1891, in the shape of the male cerci and the male subgenital plate.

Distribution: China: Guangxi Prov..
