Speonemobius bifasciatus sp. nov.

( Figs. 1–4 View FIGURES 1 – 2 View FIGURES 3 – 6 , 7–9 View FIGURES 7 – 12 )

Holotype. male, CHINA, Yunnan prov., Gongshan county, Dulongjiang , alt. 1250 m, 21.VI.2015, coll. Wenxuan Bi ( ECNU) . Paratypes: 5 males, 2 females, same data as for holotype ( ECNU) . 1 male, 1 female, same data as for holotype ( CCCC) .

Description. Male. All legs relatively long. Frontal rostrum somewhat wider than 1st antennal segment ( Figs. 3–4 View FIGURES 3 – 6 ). Eyes approximately ovoid. Pronotum pubescent and transverse, without lateral carinae, anterior margin straight, posterior margin slightly apically convex. Tegmina not extending to apex of abdomen, lacking apical area. Fore tibiae lacking outer tympanum, possessing oval-like inner tympanum, hind tibiae with three external dorsal spurs and two internal dorsal spurs. Two internal apical spurs long, and three external apical spurs fairly short, in which median external apical spurs fairly long. Genitalia long, two sides extend downward and inward, apical part membranous and expanded ( Figs. 7–9 View FIGURES 7 – 12 ).

Coloration. Body yellowish brown ( Figs. 1–2 View FIGURES 1 – 2 ). Maxillary palpus white. Four white bands on the head vertex brown and maxillary palpus white. Pronotum white and the middle of pronotum armed with brown stripe. Tegmina dark brown but veins faint yellow. Abdomen dark brown. Inside of fore and middle legs with two black thin stripe. In fore and middle legs, the joint of the tarsi and tibiae black, and the joint of tarsomere black. Both inner and outer of hind femora armed with two black stripes.

Female. General appearance somewhat similar to that of male, but with distinct differences: tegmina extremely short, veins not obvious. The 3rd segment of abdomen black, the other part of abdomen yellow with black spots. Ovipositor long and straight.

Measurements. (in mm) Body: male 7–8, female 7–8; pronotum: male 1.8–2, female 2; tegmen: male 4–4.5, female 0.8–1; hind femur: male 5–5.5, female 5–5.5; ovipositor 6.

Discussion. This new species is similar to S. decoloratus , but differs in the color of femora. In S. decoloratus , the fore and middle femora are white; the hind femora armed with a few short brown stripes on external face. But in this species, the fore and middle femora armed with white, but darkened at apex; both inner and outer of hind femora armed with two black stripes.

Etymology. Species name bifasciatus means two black stripes on hind femora.
