Eucriotettix torulisinotus View in CoL sp. nov.

( Figures 4 View Figure 4 , 5 View Figure 5 )

Female ( Figures 4A,B View Figure 4 , 5A,B View Figure 5 ). Size small. Head slightly exerted above pronotal surface ( Figures 4A View Figure 4 5A,D View Figure 5 ). Anterior margin of vertex straight, not protruding beyond eyes, median carina conspicuous. Vertex very narrow, width of one eye 1.2 times broader than width of vertex ( Figures 4A View Figure 4 , 5C View Figure 5 ); vertex and frontal ridge forming obtuse-rounded in profile ( Figures 4B View Figure 4 , 5A,D View Figure 5 ). Frontal ridge protruding between antennae, width of longitudinal furrow narrower than width of first segment of antennae ( Figure 5F View Figure 5 ). Antenna filiform, 13-segmented, inserted between lower margin of eyes, mid segments four to five times as long as wide ( Figure 5I View Figure 5 ). Eyes elevated above the pronotum ( Figures 4B View Figure 4 , 5D View Figure 5 ), globular in shape, lateral ocelli placed between middle of anterior margins of eyes ( Figure 5F View Figure 5 ).

Disc of pronotum coarse, having numerous tubercles and short carinae, mid keel of pronotum not entire, interrupted ( Figures 4A View Figure 4 , 5B View Figure 5 ), upper margin of pronotum slightly undulating before shoulders and straight behind shoulders in profile ( Figures 4B View Figure 4 , 5A View Figure 5 ). Anterior margin of pronotum straight, slightly concave in middle, lateral keels of prozona slightly constricted backwards, humeral angle obtuse, with abbreviated carinae between shoulders ( Figures 4A View Figure 4 , 5B,E View Figure 5 ). Posterior process of pronotum narrow, long coneshaped, reaching two-thirds of hind tibia ( Figure 5A View Figure 5 ). Lateral lobes of pronotum turning outwards, posterior angles pointing slightly obliquely backwards, with long spines ( Figures 4A View Figure 4 , 5E,H View Figure 5 ), posterior margin of each lateral lobe with two concavities ( Figures 4B View Figure 4 , 5D View Figure 5 ). Visible part of tegmina ovate ( Figure 5G View Figure 5 ), apex rounded. Hind wings developed, slightly not reaching apex of posterior process of pronotum ( Figures 4B View Figure 4 , 5A View Figure 5 ). Upper and lower margins of fore femur and mid femur straight ( Figure 5J,K View Figure 5 ), width of mid femur narrower than width of tegmina ( Figure 5G View Figure 5 ). Length of hind femur 3.2 times longer than wide, mid keel of dorsal and ventral side of hind femur dentate, antegenicular obtuse and genicular denticles right angle ( Figure 5L View Figure 5 ). Outer side of hind tibia with seven to nine spines, inner side with five to six spines ( Figure 5M View Figure 5 ). Length of first segment of posterior tarsus longer than third, third pulvillus longer than first and second, apices of all pulvilli obtuse ( Figure 5N View Figure 5 ). Ovipositor narrow and long, length of upper valvulae 4.0 times its width, upper and lower valvulae with slender saw-like teeth ( Figure 5O View Figure 5 ). Length of subgenital plate longer than wide, posterior margin of subgenital plate with three teeth ( Figures 4C View Figure 4 , 5P View Figure 5 ).

Body dark brown. Wings black. Fore femur and mid femur black. Hind femur and tibia dark brown.

Male. Unknown.

Holotype female, China, Guangxi, Luocheng, Qingmingshan , 24.9° N, 108.9° E, 600m alt, 03 June 2012, collected by Wei-An DENG, IZSNU GoogleMaps . Paratypes. Same data, two females, IZSNU .

Diagnosis

Eucriotettix torulisinotus sp. nov. is similar to Eucriotettix wuliangshanensis Zheng and Ou 2003 , from which it differs by: vertex and frontal ridge appearing obtuserounded in profile (vertex and frontal ridge not visible in profile in E. wuliangshanensis ); disc of pronotum coarse, having numerous tubercles and short carinae (disc of pronotum smooth in E. wuliangshanensis ); mid keel of pronotum interrupted, upper margin of pronotum slightly undulating before shoulders and straight behind shoulders in profile (mid keel of pronotum entire, upper margin of pronotum straight in profile in E. wuliangshanensis ); posterior angles of lateral lobes of pronotum with long spines (short spines in E. wuliangshanensis ); hind wings almost reaching apex of posterior process of pronotum (hind wings surpassing apex of posterior process of pronotum in E. wuliangshanensis ).

Etymology

The name of the new species is derived from Latin torulis and notus, meaning disc of pronotum coarse, having numerous tubercles and short carinae.
