Elimaea (Rhaebelimaea) yongningensis Liu C-X, sp. nov. (Plate 13e, 19l–o, 21g –k)

Holotype: male (No. 14010892), China: Hainan Island, Yongning, 1955. XI.7, Collector unknown ( MSIE).

Description: Holotype (male). Tegmina and wings well developed. Tegmen distinctly surpassing apex of hind femur. Hind wings slightly longer than tegmen. Tegmen with regular parallel cross veins, costal vein indistinct. Sc and R joining at base, then slightly separate; radius sector branching slightly before middle of R, bifurcate near apical quarter part; and R without other stems. Fore coxae unarmed. Fore femur with 6 interior ventral spines; mid femur with 6 exterior ventral spines; hind femur without ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 6 interior dorsal spines; mid tibiae with 10 exterior dorsal spines; hind tibiae with 30 large interior and 29 exterior dorsal spines, as well as with 1–5 small spines between two large spines, number of small spines increasing from base to apex.

Stridulatory file with circa 30 widely spaced large stridulatory teeth, which are of equal size, except 21 densely arranged small teeth at apical part (Plate 13e). Tenth abodominal tegum not extending backwards, with truncate apical margin (Plate 19l). Epiproct deflexed, long sheet-like, much longer than wide, basal margin widest, gradually narrowed towards basal 1/3 part, apical 2/3 part with parallel lateral margins, apical margin with a wide obtuse triangular notch (Plate 19n, 21k). Cerci arc-like in lateral view, gradually narrowed distad, exterior margin abruptly contracted at apex, joining to interior margin into a brown apical spine (Plate 19m, 21k). Subgenital plate with basal margin widest, then gradually narrowed distad; sharply narrowly excised at distal quarter part, into two subparallel lateral lobes (Plate 19o, 21j).

Color: Body yellowish green (maybe green at live). Compound eyes brown. Pronotal disc and lateral lobes densely covered with numerous scattered brown dots. Spines of each femur brown. Each cell in tegmen with a few dark brown spots, area near posterior margin with numerous dark brown dots. Lateral ventral surface of fore femur with a row of brown dots. Spines of each femur brown. Apical spine of cerci red brown.

Female unknown.

Measurement of male (mm): length of body 16.5; length of pronotum 4.0; length of tegmen 31.2; largest width of male stridulatory area 3.0; length of male stridulatory vein 2.7; largest width of dorsal area behind male stridulatory area 2.2; width of mirror on right tegmen 1.8; length of mirror on right tegmen 2.1; distance between basal vein of right tegmen and apex of mirror on right tegmen 2.7; width of tegmen 6.0; length of hind wing 35.5; length of fore femur 7.5; length of mid femur 10.0; length of hind femur 23.5; length of epiproct 1.9; length of cerci 3.7; length of subgenital plate 5.1.

(h–k). a,h, lateral lobe of pronotum of male, lateral view; b, i, male left stridulatory area, dorsal view; c, male right stridulatory area, dorsal view; d, j, male abdominal apex, lateral view; e, k, male abdominal apex, dorsal view; f, male epiproct, dorsal view; g, male cerci, dorsal view.

Etymology: The name refers to the type locality of this new species. Discussion: This new species most resembles E. (Rhaebelimaea) maichau Gorochov, 2009 in shape of the male epiproct, but distinctly differs by shape of the male stridulatory area, the male cerci, and the male subgenital plate.

Distribution: China: Hainan Prov.
