Elimaea (Rhaebelimaea) brevifissa Liu C-X & Liu X-W, sp. nov. (Plate 10d–g, 11g –I)

Holotype: male (No. 14125571), China: Hainan Island, Jianfengling, 1982. IV.20, Coll. Lin Zhiqing ( MSIE).

Paratype: 1 male, same data as in holotype ( MSIE).

Description: Holotype (male). Tegmen surpassing apex of hind femur. Hind wings slightly longer than tegmen; radius sector branching in basal 1/3 part of tegmen, emitting out 2 parallel branches after apical quarter part, and R without other stems. Fore coxae unarmed. Mid femur with 9 exterior ventral spines; hind femur without ventral spines. Genicular lobes of each femur bispinose. Each tibia dorsally sulcate and spinous.

Stridulatory file with circa 32 widely spaced stridulatory teeth, which are about of equal size (Plate 10d). Tenth abodominal tegum not extending backwards, with truncate apical margin (Plate 10e, 11l). Epiproct droopy, long triangular, with sharp triangular apex (Plate 10f, 11l). Cerci of moderate length, approximately columniform in basal half, then gradually narrowed distad, exterior margin abruptly contracted at apex, joining to interior margin into a brown horizontal apical spine (Plate 10e,g 11l,k). Subgenital plate short, not surpassing apex of cerci, with basal margin widest, then abruptly narrowed towards distal 1/3 part; sharply narrowly excised at distal 1/6 part, into two subparallel lateral lobes (Plate 11j).

Color: Body green. Compound eyes brown. Pronotal disc densely covered with numerous scattered brown dots. Cells in area between R and M in tegmen with a few dark brown spots, areas near CuIP and posterior margin with numerous dark brown dots. Spines of mid femur and each tibia brown. Apical spine of cerci red brown.

Female unknown.

Measurement of male (mm): length of body 19.7; length of pronotum 5.5; length of tegmen 37.8; largest width of male stridulatory area 4.2; length of male stridulatory vein 2.8; largest width of dorsal area behind male stridulatory area 3.5; width of mirror on right tegmen 1.8; length of mirror on right tegmen 1.7; distance between basal vein of right tegmen and apex of mirror on right tegmen 2.0; width of tegmen 6.5; length of hind wing 43.6; length of fore femur 9.0; length of mid femur 13.7; length of hind femur 26.2; length of epiproct 1.7; length of cerci 3.5; length of subgenital plate 4.8.

Etymology: The name refers to the shallow notch of the male subgenital plate.

Discussion: This new species is distinguished form its congeners by the short subgenital plate, which is not surpassing apex of cerci and split at distal 1/6 part, and the special cercial apex.

Distribution: China: Hainan Island.
