Elimaea (Elimaea) wanningensis Liu

Elimaea (Elimaea) wanningensis Liu C-X, sp. nov. (Plate 4g –j)

Holotype: female, China: Hainan Island: Wanning, 10m, 1960. IV.13, Coll. Li Xiaofu (IOZ(E)360292) (IZAS).

Description: Holotype (female). Fastigium verticis narrow, dorsally sulcate, apex obtuse triangular and steplike declined to fastigium frontis. Pronotum with disc nearly flat; medial longitudinal carina discontinuous, only distinct in anterior and posterior quarter part; transverse sulcus V-shaped; paranota circa 1.5 times longer than high, with ventral margin slightly convex, anterior and posterior angles rounded, humeral sinus distinct. Tegmen distinctly surpassing apex of hind femur; hind wings distinctly longer than tegmina; radius sector branching in circa basal quarter part. Fore coxae unarmed. Fore femur with 7 interior and 5 exterior ventral spines; mid femur with 9 interior ventral spines; hind femur with 10 exterior ventral spines. Genicular lobes of each femur bispinose. Fore tibiae without spines on both dorsal margins; mid tibiae with 13 interior and 7 exterior dorsal spines; hind tibiae with 40 interior and 40 exterior dorsal spines.

Female tenth abdominal tergum with subtruncated apical margin (Plate 4g). Epiproct long-triangular with subobtuse apex bent up. Cerci long cylindrical, moderately curved, subobtuse apical margin with small obtuse apex (Plate 4g,h). Subgenital plate acute-triangular, apex angularly excised into 2 short triangular lateral lobes (Plate 4i). Gonangulum of ovipositor with ventro-apical appendage pointing apically upwards (Plate 4j).

Color: Body yellowish green. Compound eyes brown. Pronotum, cells of tegmen except those of the costal area, exposed part of hind wing and abdomen with numerous reddish brown dots. Discontinuous median longitudinal pronotal carina red brown.

Male unknown.

(Scale bar = 1 mm)

Measurement of female (mm): length of body 26.0; length of pronotum 5.0; length of tegmen 37.5; width of tegmen 6.5; length of hind wing 44.0; length of fore femur 9.8; length of mid femur 12.0; length of hind femur 26.5; length of cerci 3.7; length of subgenital plate 3.2; length of ovipositor 7.5.

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

Discussion: This new species maybe belongs to the species complex fallax-thaii Gorochov, 2009, for the shape of gonangulum of ovipositor, but differs from the species in the complex in the shape of the female cerci and the female subgenital plate.

Distribution: China: Hainan Island.
