Elimaea (Rhaebelimaea) albovittata Liu C-X & Liu X-W, sp. nov. (Plate 13b–c, 19f, 20g –l)

Holotype: male (No. 14022262), China: Jiangxi Prov., Jiunianshan Mt., 1986. IX.18, Coll. Zheng Jianzhong ( MSIE).

Paratype: 1 male, same data as holotype ( MSIE); 1 female (No. 14021928), similar data as in holotype, but 500m, 1986. IX.14 ( MSIE); 1 male, China: Fujian Prov., Jiangle, Jiangjunding, 800m, 1990. IX.16, Coll. Huang Chunmei ( MSIE).

Description: Tegmen distinctly surpassing apex of hind femur; hind wings much longer than tegmen; radius sector branching slightly before middle of tegmen, and emitting out 2 parallel branches behind middle; and R without other stems. Fore coxae unarmed. Fore femur with 5–9 interior ventral spines; mid femur with 14 exterior ventral spines; hind femur without interior ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 3 interior dorsal spines; mid tibiae with 4 interior and 5 exterior dorsal spines; hind tibiae with 34 interior and 38 exterior large dorsal spines, as well as with 0–5 small spines between two large spines.

Stridulatory file with circa 84 stridulatory teeth, which are gradually becoming larger mediad (Plate 13a–b). Tenth abdominal tergum slightly produced, apical margin truncate, with slightly obtuse rounded concavity in surface of distal half. Epiproct deflexed, trapeziform, slightly longer than wide, with obtuse apex (Plate 19f, 20k). Cerci approximately columniform in basal half, gradually narrowed from middle, and abruptly acuminated at apex into a sharp apical spine directing mediad (Plate 19f, 20j–k). Subgenital plate with basal margin widest, then gradually narrowed to the middle part and lateral margins subparallel in distal half; split from basal half, with very narrow excision (Plate 19f, 20k,l).

Color: Body yellowish green. Compound eyes brown. Longitudinal midline of occiput and pronotal disc grayish white. Pronotal disc and each 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. Spines of each femur and hind tibia black. Spines of fore and mid tibiae brown. Apical spine of cerci red brown.

Female. Epiproct tongue-shaped. Cerci conical, with obtuse apex. Subgenital plate spoiled. Ovipositor falcate, strongly upcurved, dorsal margin with upcurved 3/4 part crenulated and ventral margin only with apical 1/6 part crenulated. Gonangulum of ovipositor without distinct ventral projection.

Measurement (mm): length of body: male 21.0, female 20; length of pronotum: male 4.7, female 4.5; length of tegmen: male 34.5, female 38.5; largest width of male stridulatory area 3.0; length of male stridulatory vein 2.5; largest width of dorsal area behind male stridulatory area 2.0; width of mirror on right tegmen 2.0; length of mirror on right tegmen 2.2; distance between basal vein of right tegmen and apex of mirror on right tegmen 5.0; width of tegmen: male 5.0, female 5.8; length of hind wing: male 40.5, female 45.0; length of fore femur: male 10.0, female 10.1; length of mid femur: male 13.5, female 15.5; length of hind femur: male 26.5, female 28.5; length of epiproct: male 2.5, female 1.5; length of cerci: male 2.5, female 1.9; length of subgenital plate: male 5.0; ovipositior 9.0.

Etymology: The name refers to the grayish white longitudinal midline of occiput and pronotal disc.

Discussion: This new species most resembles E. (Rhaebelimaea) pseudochloris Ingrisch, 1998 and E. (Rhaebelimaea) brachycerciata sp. nov. in shape of the lateral lobes of the male subgenital plate, but differs by shape of the male cerci. It also resembles E. (Rhaebelimaea) brachycerciata sp. nov. in the appearance, tegminal stridulatory area, and coloration.

Distribution: China: Jiangxi Prov., Fujian Prov.
