Elimaea (Elimaea) paranautica Liu C-X, sp. nov. (Plate 6a–e)

Holotype: male, China: Guangxi Prov., Longzhou, Xiangshui, Changzheng, 1980. VI.11, Coll. Liang Xianfa ( IZAS).

Description: Holotype (male). Tegmen surpassing apex of hind femur; hind wing longer than tegmen; radius sector branching in basal quarter part, and emitting out 3 branches behind middle. Fore coxae unarmed. Fore femur with 7 interior and 3 exterior ventral spines; mid femur with 12 exterior ventral spines; hind femur with 10 exterior ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 1 exterior dorsal spine as well as 1 exterior dorsal spine over tympana; mid tibiae with 7 interior and 4 exterior dorsal spines; hind tibiae with 40 interior and 38 exterior dorsal spines.

PLATE 6, a–e, Elimaea paranautica sp. nov.; f–i, Elimaea upcurva sp. nov. a,f, lateral lobe of pronotum of male, lateral view; b, stridulatory file on underside of left tegmen; c, g, male abdominal apex, lateral view; d, male subgenital plate, ventral view; e, male cerci, dorsal view; h, male cerci, apico-lateral view; i, male subgenital plate, apico-ventral view. (Scale bar = 1 mm)

Stridulatory file with about 33 rather large widely arranged teeth, which are becoming smaller distad (Plate 6b). Tenth abdominal tergum slightly prolonged, with wide obtuse apical margin (plate 6c). Epiproct long, droopy, approximately triangular, with sharp angular apex. Cerci approximately columned, incurved, exterior margin slightly concave from distal quarter, interior margin abruptly acuminated at distal part, apex with a sharp spine (Plate 6e). Subgenital plate gradually upcurved, split from apical half into two slit-like cross lateral lobes (Plate 6d).

Female unknown.

Color: Green. Compound eyes brown. Mid line of pronotal disc brown. Pronotal disc densely covered with dark brown dots; cells in area between R and Rs, Rs and M with a few brown dots; area between CuA and posterior margin sparsely with aggregations of dark brown dots; exposed part of hind wing with a row of dark brown spots. Distal half of each femur densely with dark brown dots. Ventral spines of each femur and apex of cerci brown.

Measurement of male (mm): length of body 22.0; length of pronotum 4.4; length of tegmen 36.5; largest width of male stridulatory area 2.5; length of male stridulatory vein 2.0; largest width of dorsal area behind male stridulatory area 1.1; 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 5.8; length of hind wing 41.5; length of fore femur 8.0; length of mid femur 10.5; length of hind femur 24.0; length of epiproct 1.5; length of cerci 3.0; length of subgenital plate 8.0.

Etymology: The name shows that this new species is very similar to E. nautica .

Discussion: The new species resembles E. nautica Ingrisch, 1998 in the size, coloration of midline of pronotal disc, length and shape of wings, and structure of the male subgenital plate, but differs by the triangular male epiproct, number of the male stridulatory file and apex of male cerci.

Distribution: China: Guangxi Prov..
