description: Elimaea (Rhaebelimaea) tenuicerca Liu C-X & Liu X-W, sp. nov. (Plate 12f, 16g –j, 18g –l)
Holotype: male, at light, China: Tibet, Aniqiao, 1250m, 2006. VIII.12, Coll. Liu Chunxiang (IZAS).
Paratype: 1 male (No. 14200051), similar data as in holotype, but, 1979. VII.20, Coll. Jin Gentao, Wu Jianyi (MSIE).
Description: Holotype (male). Tegmen surpassing apex of hind femur; hind wings slightly longer than tegmen; radius sector branching in middle of tegmen, bifurcate near apical 1/3 part; and R without other stems. Fore coxae unarmed. Fore femur with 10 interior and 5 exterior ventral spines; mid femur with 13 exterior ventral spines; hind femur with 20 exterior ventral spines. Genicular lobe of each femur bispinose. Fore tibiae with 3 interior and 6 exterior dorsal spines; mid tibiae with 7 interior dorsal spines; hind tibiae with 25 interior and 30 exterior dorsal spines.
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 12f). Tenth abdominal tergum not produced, apical margin with slightly obtuse concavity (Plate 16g). Epiproct long, droopy, triangular. Cerci gradually narrowed distad, and abruptly narrowed from middle into a robust spine at apex, which curved mediad (Plate 16h,i, 18j,k). Subgenital plate with basal margin widest, then gradually narrowed to the middle part, and lateral margins subparallel in distal half; split from basal 1/ 3 part, with very narrow excision, and subparellel apical lateral lobes (Plate 16g,j, 18l).
Color: Body yellowish green. Compound eyes brown. Lateral margins of occiput with dark brown lateral stripes. Lateral margins of pronotal disc and distal half of hind femur densely covered with numerous scattered brown dots. Veinlets of tegminal stridulatory area and posterior margin dark brown. Hind half of tegminal costal area and area between Cu vein and posterior margin densely covered with numerous dark brown dots. Cells of tegmen between R vein and Rs vein with one brown spot. Slit of anterior tibial tympana brown. Ventral spines of each femur black, and spines of each tibia yellow.
Female unknown.
Measurement of male (mm): length of body 22.5; length of pronotum 5.5; width of pronotal disc at base 2.5; width of pronotal disc at apex 3.0; length of tegmen 43.2; largest width of male stridulatory area 3.5; length of male stridulatory vein 3.0; largest width of dorsal area behind male stridulatory area 2.5; width of mirror on right tegmen 3.0; length of mirror on right tegmen 3.5; distance between basal vein of right tegmen and apex of mirror on right tegmen 4.1; width of tegmen 7.5; length of hind wing 45.0; length of fore femur 14.0; length of fore tibiae 12.5; length of mid femur 15.0; length of mid tibiae 14.4; length of hind femur 32.5; length of hind tibiae 32.5; length of epiproct 2.1; length of cerci 5.0; length of subgenital plate 5.5.
Etymology: The name refers to the tenuous male cerci.
Discussion: This new species is distinguished from its congeners by the tenuous male cerci. It most resembles E. (Rhaebelimaea) beibengensis sp. nov. in the appearance, coloration, head, pronotum, and tegmen, but distinctly differs by the branching location of Rs, and the male abodominal apex.
Distribution: China: Tibet.
