Elimaea (Rhaebelimaea) nanpingensis Liu C-X, sp. nov. (Plate 8a–c)

Holotype: female, China: Fujian Prov.: Nanping, Shangyang, 1963. VI.8, Coll. Zhang Youwei [IOZ(E)360370].

Paratype: 2 females, China: Fujian Prov.: Chong’anxingcun, Sangang, 740m, 1960. VII.7–VIII.12, Coll. Zuo Yong [IOZ(E)360343-360344] ( IZAS).

Description: Holotype (female). Fastigium verticis narrow, dorsally sulcate, apex obtuse triangular and steplike declined toward fastigium frontis. Pronotum with disc nearly flat; medial longitudinal carina distinct; median transverse sulcus V-shaped; paranota circa 1.3 times longer than high, with ventral margin slightly convex, anterior and posterior angles rounded, humeral sinus distinct. Tegmen surpassing apex of hind femur; hind wings distinctly longer than tegmen; radius sector branching slightly before middle of tegmen. Fore coxae unarmed. Fore femur with 8–10 interior ventral spines; mid femur with 13–16 exterior ventral spines; hind femur with 5–6 exterior ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 3 exterior dorsal spines; mid tibiae with 10 interior and 3 exterior dorsal spines; hind tibiae with 36 interior and 34 exterior dorsal spines.

Female tenth abdominal tergum with apical margin strongly concave in middle into a trapezoid extending outwards (Plate 8a). Epiproct long-trapezium, apical margin truncated, lateral margins contracted backwards (Plate 8a). Cerci moderately long conical, moderately curved, subobtuse apical margin with small obtuse apex (Plate 8a). Subgenital plate transverse, apical margin with a long spinose projection at each lateral angle and area between rather wide, slightly convex and subtruncate (Plate 8b). Gonangulum of ovipositor with a small ventro-apical appendage pointing ventrad (Plate 8c).

Color: Body green. Compound eyes brown. Pronotal disc with scattered brown dots; occiput, lateral lobes of pronotum, and tegminal costal area with numerous scattered red brown dots; cells of tegmen between R vein and posterior margin, exposed part of hind wing and abdomen with aggregations of numerous brown dots.

Male unknown.

Measurement of female (mm): length of body 24.0; length of pronotum 4.5; length of tegmen 33.5; width of tegmen 5.9; length of hind wing 40.0; length of fore femur 9.6; length of mid femur 14.0; length of hind femur 26.0; length of cerci 3.2; length of subgenital plate 2.8; length of ovipositor 7.0. Etymology: The name refers to the type locality of this new species.

Discussion: This species resembles most species of the subgenus Rhaebelimaea by the transverse female subgenital plate, but differs by the distinctly long sharp spinose lateral projections. It resembles E. jianfenglingensis sp. nov. in the transverse female subgenital plate, but differs by the size, structure of tegmen, cerci, spinose projection of the female subgenital plate and gonangulum of ovipositor. The spinose projection of the female subgenital plate also resembles those of 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 , E. (Rhaebelimaea) abdita Gorochov, 2009 , but differs from them by the details of the apical margin of the plate.

Elimaea (Rhaebelimaea) guadunensis Liu C-X, sp. nov. (Plate 8d–f)

Holotype: female, China: Fujian Prov.: Chong’anxingcun, Guadun, 1960. VIII.20, Coll. Zuo Yong ( IZAS).

Paratype: 1 female, China: Fujian Prov.: Chong’anxingcun, jianfengling, 850-1170m, 1960. IV.6, Coll. Zuo Yong [IOZ(E)360349] ( IZAS).

Description: Holotype (female). Fastigium verticis narrow, dorsally sulcate, apex obtuse triangular and steplike declined toward fastigium frontis. Pronotum with disc nearly flat; medial longitudinal carina distinct; median transverse sulcus V-shaped; paranota circa 1.5 times longer than high, with ventral margin slightly oblique backwards, anterior and posterior angles rounded, humeral sinus distinct. Tegmen surpassing apex of hind femur; hind wings distinctly longer than tegmen; radius sector branching slightly before middle of tegmen. Fore coxae unarmed. Fore femur with 8 interior ventral spines; mid femur with 8 exterior and 1 interior ventral spines; hind femur without any ventral spines. Genicular lobes of each femur bispinose. Fore tibiae with 7 exterior dorsal spines; mid tibiae with 9 interior dorsal spines; hind tibiae with 8 interior and 14 exterior dorsal spines.

Female. Tenth abdominal tergum with subtruncated apical margin, slightly concave in middle (Plate 8d). Epiproct long trapezoidal, apical margin truncated, lateral margins contracted backwards (Plate 8d). Cerci moderately long, conical, moderately curved, subobtuse apical margin with small obtuse apex (Plate 8d). Subgenital plate transverse, apical margin with a very small triangular projection at each lateral angle and area between very wide, distinctly concave (Plate 8e). Gonangulum of ovipositor with a small ventro-apical appendage pointing ventrad (Plate 8f).

Color: Body yellowish green. Compound eyes brown. Pronotal disc with scattered brown dots; occiput, lateral lobes of pronotum, surface of hind femur, abdomen and tegminal costal area with numerous scattered red 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. Pronotal median longitudinal carina reddish brown.

Male unknown.

Measurement of female (mm): length of body 25.5; length of pronotum 4.5; length of tegmen 34.0; width of tegmen 5.5; length of fore femur 9.5; length of mid femur 13.5; length of hind femur 26.0; length of cerci 3.0; length of subgenital plate 1.7; length of ovipositor 7.5.

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

Discussion: This species resembles most species of the subgenus Rhaebelimaea by the transverse female subgenital plate, but differs by the distinctly short robust spinose lateral projection. It most resembles E. (Rhaebelimaea) modiglianii Ingrisch, 1998 and E. (Rhaebelimaea) suratthani Gorochov, 2009 in the short robust spinose lateral projection, but differs by the shape of the apical margin of the plate. It resembles E. jianfenglingensis and E. nanpingensis in the transverse female subgenital plate, but differs from E. jianfenglingensis by the size, tegmen, cerci, spinose projection of subgenital plate and gonangulum of ovipositor; it also resembles E. nanpingensis in the size, coloration, the shape of epiproct but differs by the female tenth abdominal tergum and projection of female subgenital plate.

Distribution: China: Fujian Prov.
