Description:
Holotype
(male). Tegmen extending far beyond apex of hind femur; hind wing distinctly longer than tegmen; radius sector branching slightly before middle of tegmen, and bifurcate behind middle. Fore coxae unarmed. Fore femur with 7 interior and exterior ventral spines; mid femur with 15 exterior ventral spines; hind femur with 14 interior and 11 exterior ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 1 exterior dorsal spine over tympana; mid tibiae with 2 interior and 7 exterior dorsal spines; hind tibiae with about 70 interior and exterior dorsal spines.
Tenth abdominal tergum truncated (Plate 9h, 10h). Epiproct long quadriangular (Plate
9g
, 10l). Cerci approximately columned, gradually incurved, abruptly acuminated at apex, and shaped into a brown spine (Plate 10k). Subgenital plate rather complex, split at basal 1/6 part into two lateral lobes, which initially divergent, abruptly contract and joining each other in middle of the subgenital plate, and then extending backwards; each lobe split at apical 1/6 part into two sharp spines, among which the interior spine reversely upcurved, and the exterior one perpendicularly upcurved (Plate 9h–k, 10h–j).
Color:
Body yellowish green (maybe green at live). Compound eyes brown. Lateral corner of occiput with a brown spot. Pronotal disc brown. Anterior tibial tympana dorsally brown. Proximal corner of tegminal stridulatory apparatus with a dark brown spot. Tegminal anterior margin red brown, area between M and Cu vein, which approximates Cu vein, and area near posterior margin densely covered with brown dots; each cell between R and Rs veins with a brown spot. Apical spine of cerci and sharp apical spine of subgenital plate brown.
Female unknown.
Measurement of male (mm):
length of body: 19.0–22.5; length of pronotum: 5.2–6.0; length of tegmen: 39.0– 42.0; largest width of male stridulatory area 3.0; length of male stridulatory vein: 2.5; largest width of dorsal area behind male stridulatory area: 1.8; width of tegmen: 6.5; length of hind wing: 44.0–47.5; length of fore femur: 7.0; length of mid femur: 10.5; length of hind femur: 24.5; length of epiproct: 2.0; length of cerci: 4.0; length of subgenital plate: 8.0.
Etymology:
The name shows that this new species possesses special apical four spines of the male subgenital plate.
Discussion:
This new species is distinguished form its congeners by the male abdominal apex, especially its special male subgenital plate.
Distribution:
China
: Yunnan Prov.
