Sphedanolestes rubripes , new species

( Figs. 1-10 )

Material examined. – Holotype – female, Jinghong, Yunnan, coll. Xiong Jiang, 22 Aug.1973 ( KZI).

Paratype – 1 male, Jinghong, Yunnan, coll. Yang Pingzhi, 2 May.1981 ( KZI) .

Diagnosis. – Sphedanolestes rubripes is similar to S. trichrous and S. xiongi in general coloration and body plan. But the new can be easily distinguished from the later two species by the legs uniformly reddish.

Description. – Colour. Bright red to dark red, shining. Eye reddish brown scattered with irregular blackish brown markings; second to fourth antennal segments, apices of tibiae dark brown to blackish brown; legs reddish brown to dark brown; venter of female blackish brown.

Structure. Medium sized, somewhat robust. Rostrum, head above and beneath, pronotum scattered with yellowish brown setae. Thoracic pleura and sterna densely covered with pale yellow fine short setae, hemelytron densely with short bent setae. Head somewhat thick; eyes big, prominently laterally protruded; rostrum short and thick, first segment subequal to second ( Fig. 2 ); first antennal segment longer than second and third segments together, second segment slightly longer than third, third segment shortest. Collar process less developed, short corn-shaped, apex with a somewhat long seta; posterior lobe of pronotum developed, median longitudinal depression deep, posterior angle not distinct, posterior margin nearly straight; stridulatory furrow consisting of 170 transverse ridges; legs somewhat thick, femora distinctly nodulose, distal portion of right fore leg and left hind leg showing in Fig. 3 and Fig. 4 respectively. Abdomen wide and short, not laterally dilated ( Fig. 5 ); abdominal tip of female showing in Figs. 5-7 . Pygophore process short and wide ( Figs. 8, 9 ); clasper distinctly bent ( Fig. 10 ).

Measurements. Body length 11.1(male), 11.2 (female); maximum width of abdomen 2.9(male), 3.1 (female). Head length 1.4 (male), 1.6(female); length of anteocular part 0.5 (male), 0.5(female); length of postocular part 0.5(male), 0.6 (female); length of synthlipsis 0.4(male), 0.5(female); distance between ocelli 0.2 (male), 0.3 (female); length of antennal segments I:II:III:IV=3.0 (male), 2.9 (female): 1.4 (male), 1.4 (female): 1.2 (male), 1.2 (female):? (male), 3.0 (female); length of rostral segments I:II:III=1.0 (male), 0.9 (female): 1.1(male), 1.0 (female): 0.2 (male), 0.2 (female). Length of anterior lobe of pronotum 0.7 (male), 0.8 (female); length of posterior lobe of pronotum 2.0(male), 1.8 (female); maximum width of thorax 2.3 (male), 3.2 (female); length of scutellum 1.1 (male), 1.1 (female); length of hemelytron 9.0 (male), 7.8 (female).

Distribution. – China (Yunnan).

Etymology. – The new species is named for its total reddish femur.
