Elimaea (Elimaea) cangyuanensis Liu C-X, sp. nov. (Plate1a–g, 2a–g)

Holotype: male, China: Yunnan Prov.: Cangyuan, 1981. VI.24, Coll. Gan Yunxing ( IZKAS). Paratype: 1 female, same data as in holotype ( IZKAS).

Description: Holotype (male). Fastigium verticis narrow, dorsal surface sulcate; slightly declined toward fastigium frontis. Pronotum with disc flattened and lateral angles rounded; transverse sulcus V-shaped; medial longitudinal carina distinct; anterior margin substraight or slightly concave, posterior margin rounded; lateral lobe of pronotum 1.1 times longer than high, anterior and posterior ventral angles rounded; humeral sinus distinct (Plate 2a). Tegmen surpassing hind knees, hind wing distinctly longer than tegmen; radial sector branching circa in basal quarter part of tegmen. Fore femur with ventral spines on both margins, mid and hind femora with exterior ventral spines. Fore tibiae with exterior dorsal spines, mid tibiae with interior dorsal spines, hind tibiae with exterior dorsal spines. Each femur with genicular lobe bispinose.

Stridulatory file with circa 41 teeth which becoming larger mediad and widely spaced in basal 2/3 part (Plate 1a). Tenth abdominal tergum with broadly rounded apical margin (Plate 1b, 2d). Epiproct tongue-shaped, bent up at apex, with many black bristles close to and around apical margin. Cerci equally curved and gradually acuminated; apical area slightly inflated with exterior surface slightly concave and sinuate, and interior surface convex and sinuate to the apex, which is directing dorsad (Plate 1c, 2d). Subgenital plate long and narrow, with a medial carina in basal half; split into two long slice-like lobes in circa apical half, which are slightly crossing together (Plate 1d, 2e).

PLATE 1, Elimaea cangyuanensis sp. nov.. a, stridulatory file on underside of left tegmen; b, male abdominal apex, lateral view; c, male cerci, dorsal view; d, male subgenital plate, ventral view; e, female abdominal apex, lateral view; f, the gonangulum at the base of the ovipositor, lateral view; g, female subgenital plate, ventral view. (Scale bar = 1 mm)

Female. Epiproct long-triangular, apex bent up. Cerci short, slightly curved, gradually acuminated to apex (Plate 1e, 2f). Subgenital plate long-triangular, apical margin roundly excised in middle into two short obtuse triangular lateral projections (Plate 1g, 2g). Gonangulum of ovipositor with a small ventro-apical appendage pointing ventrally backwards (Plate 1f).

Color: Pronotal disc densely with dark brown dots; area between CuA and posterior margin sparsely with aggregations of dark brown dots; cells of area in apical half part between CuA and Rs vein with aggregations of dark brown dots. Part of male striduatory area before second cross vein dark brown.

Measurement (mm): length of body: male 19.0, female 18.0; length of pronotum: male 4.5, female 4.5; length of tegmen: male 35.2, female 30.5; largest width of male stridulatory area 2.2; length of male stridulatory vein 2.0; largest width of dorsal area behind male stridulatory area 1.5; width of mirror on right tegmen 1.0; length of mirror on right tegmen 1.5; distance between basal vein of right tegmen and apex of mirror on right tegmen 2.0; width of tegmen: male 5.8, female 5.0; length of hind wing: male 41.0, female 37.0; length of fore femur: male 8.5–9.0, female 11.0; length of mid femur: male 13.0, female 17.0; length of hind femur: male 24.5–26.0, female 24.5; length of epiproct: male 1.0, female 0.9; length of cerci: male 2.1, female 1.1; length of subgenital plate: male 5.2, female 1.5; length of ovipositor 7.0.

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

Discussion: This new species maybe belongs to the species complex fallax-thaii Gorochov, 2009, for the shape of the male subgenital plate, and distinctly differs from the species in the complex by the structure of the male stridulatory file, and the shape of the female subgenital plate.

Distribution: China: Yunnan Prov..
