Sphedanolestes xiongi , new species

( Figs. 21-28 )

Material examined. – Holotype - female, Lewen, Mengyang, Mengla, Yunnan, coll. Xiong Jiang, 8 Jun.1984 ( KZI).

Paratype – 1 female, Jinghong, coll. Yang Darong, 8 Jun.1984 ( ZRC) .

Diagnosis. – The general colouration and size of this new species are similar to those in S. rubripes , new species. But the former with its femora annulated and obsoletely nodulose, and the second antennal segment distinctly shorter the third segment, whereas, S. rubripes , new species, with its femora unicolorous and distinctly nodulose, and the second and third antennal segments subequal in length.

Description. – Colour. Orange, shining. Eyes, annuli on femora, tibiae (except bases), tarsi, basal half of each segment of connexivum dark brown to black; subbasal part of first antennal segment and apical 3 antennal segments dark brown to blackish brown.

Structure. Medium sized, somewhat robust. Head above scattered with somewhat long yellow setae; posterior half of anterior lobe of pronotum, posterior lobe of pronotum densely covered with short yellow setae; thoracic pleuron and sterna densely cover with short pubescent, abdomen beneath scattered with yellow setae in different length. Head relative long and slender; eyes big, distinctly laterally and ventrally protruded, eye diameter longer than distance between ocelli; first rostral segment distinctly shorter than the second ( Fig. 22 ); first antennal segment subequal to second and third antennal segments together, second antennal segment distinctly shorter than third segment. Collar process not developed, tubercle-shaped; anterior pronotal lobe small, posteriorly with two tuberculated processes; posterior lobe of pronotum budged, middle longitudinal depression shallow, posterior margin relative short; stridulatory furrow consisting of about 180 transverse ridges; hind femur slightly bent, fore leg and apical portion of hind leg showing in Figs. 24, 25 ; hemelytron distinctly surpassing abdominal tip. Abdominal tip of female showing in Figs. 26-28 .

Measurements. Body length 12.6-13.1(female); maximum width of abdomen 3.2-4.0 (female). Head length 2.2(female); length of anteocular part 1.0(female); length of postocular part 0.6-0.7(female); length of synthlipsis 0.5-0.6(female); distance between ocelli 0.3 (female); length of antennal segments I:II:III:IV=3.0-3.1 (female): 1.2-1.5 (female): 1.2- 1.6 (female):2.6 (female); length of rostral segments I:II:III=1.1-1.2(female): 1.5-1.7(female): 0.2-0.3(female). Length of anterior lobe of pronotum 0.9 (female); length of posterior lobe of pronotum 1.9 (female); maximum width of thorax 3.1-3.2 (female); length of scutellum 1.2(female); length of hemelytron 8.9-9.0(female).

Distribution. – China (Yunnan).

Etymology. – The new species is named after Prof. Xiong Jiang, the collector of the holotype and formerly the head of the Kunming Zoological Institute, for his contribution to the taxonomy of Heteroptera of China.

Male. – Unknown.
