Elimaea (Rhaebelimaea) tiankengensis Liu C-X, sp. nov. (Plate 8g,h, 9a–d)

Holotype: female, China: Guangxi Prov.: Leye, Tiankeng, 2005. XII.11, Coll. Zhang Chunguang ( IZAS).

Description: Holotype (female). Tegmen surpassing apex of hind femur; hind wings distinctly longer than tegmen; radius sector branching slightly before middle of tegmen, emitting out 3 branches after basal quarter. Fore coxae unarmed. Fore femur with 6 interior ventral spines; mid femur with 6 exterior ventral spines; hind femur without any ventral spines. Genicular lobes of each femur bispinose. Each tibia dorsally spinose and sulcate.

PLATE 9, Color photograph of Elimaea tiankengensis sp. nov. (a–d), and Elimaea quadrispina sp. nov. (e–k). a, female head and pronotum, lateral view; e, lateral lobe of pronotum of male, lateral view; b, female pronotum, dorsal view; c, female abdominal apex, lateral view; d, female subgenital plate, ventral view; f, male left stridulatory area, dorsal view; g, male abdominal apex, lateral view; h, male abdominal apex, lateral view, i, male subgenital plate, apico-lateral view; j, male subgenital plate, apico-ventral view; k, male subgenital plate, ventral view.

Female tenth abdominal tergum with subtruncated apical margin, slightly concave in middle (Plate 8g, 9c). Epiproct long triangular, upcurved (Plate 8g, 9c). Cerci moderately long conical, moderately curved (Plate 8g, 9c). Subgenital plate transverse, lateral corner with a long and a small triangular projection, among which the former as long as half of the subgential plate, middle of apical margin wide triangular projecting (Plate 8h, 9d). Gonangulum of ovipositor with a small ventro-apical appendage pointing laterad.

Color: Green. Compound eyes slightly brown. Pronotal disc and dorsal area of lateral lobe of pronotum scattered with numerous dark brown dots (Plate 9a,b); distal half of hind femur scattered with numerous brown dots, and tegminal costal area with numerous scattered slightly brown dots; cells of tegmen between R vein and posterior margin and exposed part of hind wing and abdomen with aggregations of numerous brown dots.

Male unknown.

Measurement of female (mm): length of body 17.5; length of pronotum 4.2; length of tegmen 32.5; width of tegmen 4.5; length of hind wing 38.1; length of fore femur 11.5; length of mid femur 14.5; length of hind femur 27.5; length of epiproct 1.5; length of cerci 3.0; length of subgenital plate 2.5; length of ovipositor 7.5.

Etymology: The name refers to the habitat of this new species – Tiankeng.

Discussion: This species resembles most species of the subgenus Rhaebelimaea by the transverse female subgenital plate, but differs by the lateral corner with a long and a small triangular projection, among which the former as long as half of the subgential plate, and middle of apical margin wide triangular. It most resembles E. (Rhaebelimaea) tenuiuscula Gorochov, 2009 , in the spinose projections of the female subgenital plate, but differs by the shape of the subgenital plate. It also resembles E. hunanensis Kang and Yang, 1992 , E. (Rhaebelimaea) pentaspina Ingrisch, 1998 , E. (Rhaebelimaea) orlovi Gorochov, 2009 , E. (Rhaebelimaea) gialai Gorochov, 2009 , E. (Rhaebelimaea) bengkulu Gorochov, 2009 , E. (Rhaebelimaea) ryabovi Gorochov, 2009 , and E. (Rhaebelimaea) abdita Gorochov, 2009 , but differs from them by the details of the lateral and medial projections of the plate.

Distribution: China: Guangxi Prov.
