Elimaea (Elimaea) lanpingensis Liu C-X, sp. nov. (Plate 2h–n, 3a–j)

Holotype: male, China: Yunnan Prov.: Lanping, 1983. IX.21, Coll. Liang Xingcai ( IZKAS).

Paratype: 1 female, same data as in holotype, but collecting data is 1983. IX.22 ( IZKAS).

Description: Holotype (male). Fastigium verticis narrow with obtuse apex, acute-angular in dorsal view, dorsal surface furrowed but ridged in middle, slightly deflexed towards fastigium frons (Plate 3a). Pronotum with disc flattened in posterior area, lateral margin rounded; longitudinal medial carina distinct, transverse sulcus slightly behind middle, V-shaped; lateral lobe of pronotum 1.2 times longer than high; posterior lateral corner rounded; humeral sinus distinct (Plate 2h, 3c). Tegmen surpassing hind knees, hind wing slightly longer than tegmen; radial sector branching circa in basal 1/3 part of tegmen (Plate 3b). Fore femora without ventral spines, mid and hind femur with exterior ventral spines. Fore tibiae without dorsal spines, mid and hind tibiae with dorsal spines on both margins. Genicular lobes of fore and mid femora bispinose and those of hind femur obtuse.

Stridulatory file with about 22 rather large widely arranged teeth in basal 2/3 area and with several small densely arranged obsolescent teeth in distal 1/3 part (Plate 3d). Tenth abdominal tergum slightly prolonged and apical margin obtuse broad triangular (Plate 2k, 3e). Epiproct long triangular. Cerci rather strongly curved, apical area slightly sinuate, with convex external and concave internal surface, acute apex curved ventrad (Plate 2m, 3f). Subgenital plate narrow and long, slightly curved dorsad, with a distinct medial carina, and with hind median notch longer than median part of this plate (Plate 2l, 3e).

Female. Female femur with each genicular lobe bispinose. Tenth abdominal tergum with apical margin subtruncate. Epiproct long-triangular, apex subacute (Plate 2n, 3h). Cerci moderately curved, slender long, gradually acuminated into subobtuse apex (Plate 3h). Subgenital plate long triangular, apical margin rather broadly excised in middle, subtruncate between two short obtuse lateral triangular projections (Plate 3i). Gonangulum of ovipositor with a small ventro-apical appendage pointing backwards (Plate 3j).

Color: Occiput and pronotum dorsally brown; lateral lobe of pronotum sparely covered with brown dots; area between CuA and posterior margin sparsely covered with dark brown dots; cells of area between CuA and R vein with brown dots, and cells close to the apex, with comparatively sparse brown dots; apex of cerci brown.

Measurement (mm): length of body: male 19.0, female 20.0; length of pronotum: male 4.0, female 3.5; length of tegmen: male 25.5, female 24.5; largest width of male stridulatory area 2.0; length of male stridulatory vein 1.7; largest width of dorsal area behind male stridulatory area 1.5; width of mirror on right tegmen 0.9; length of mirror on right tegmen 1.0; distance between basal vein of right tegmen and apex of mirror on right tegmen 2.0; width of tegmen: male 4.0, female 4.5; length of hind wing: male 26.0, female 28.5; length of fore femur: male 7.5, female 7.0; length of mid femur: male 8.5, female 8.5; length of hind femur: male 20.0, female 18.5; length of epiproct: male 0.9; length of cerci: male 2.9, female 2.0; length of subgenital plate: male 4.0, female 1.0; length of ovipositor 7.5.

(h–n). a,h, lateral lobe of pronotum of male, lateral view; b,i, male left stridulatory area, dorsal view; c,j, male right stridulatory area, dorsal view; d,k, male abdominal apex, lateral view; e,l, male subgenital plate, ventral view; f,n, female abdominal apex, lateral view; g, female subgenital plate, ventral view; m, male cerci, dorsal view.

Etymology: The name refers to the type locality of this new species.

Discussion: The new species maybe belongs to the species complex fallax-thaii Gorochov, 2009, for the shape of the male subgenital plate, and differs from the species in the complex by the distinctly short wings, the hind wings which are slightly longer than tegmen, the structure of the male stridulatory file, and the shape of the female subgenital plate.

Distribution: China: Yunnan Prov.
