(Figs. 1–7)
Description. Color. Body dark brownish black to black, distinctly shiny. Head (except three round spots), antenna, leg (except basal 2/3 of mid and hind femora), posterior pronotal lobe, meso­ and metapleura, meso­ and metasterna, scutellum, corium, most of second abdominal sternum brownish black to black; two round spots around ocelli and a round spot in middle of vertex, neck, collar, anterior pronotal lobe (except irregular yellow markings), propleuron, prosternum, fore coxae, basal 2/3 of mid and hind femora, ventral and dorsal surfaces of abdomen (except most sternum of first abdominal segment and irregular yellow markings) orange to yellowish red; clavus and membrane (except veins) brown and semitransparent; irregular thin stripes on ventral surface of abdomen, irregular thin stripes on anterior pronotal lobe yellowish; eyes black with irregular yellow markings; ocelli light yellow.
Structure. Body (except glabrous part) scattered with pale yellow fine setae of different lengths. Dorsal and lateral surfaces of head, scutellum and ventral surface of abdominal tip scattered with light brown long setae; first antennal segment with scattered oblique setae, remaining segments with dense short oblique setae; lower surfaces of legs densely clothed with oblique short setae and few long setae, apical half of tibiae densely clothed with oblique setae; corium clothed with short bent setae. Head elliptical; first antennal segment thickest and slightly longer than second segment, second nearly as long as third, fourth segment shortest; first rostral segment extending beyond middle of eye, second segment subequal to first in length; interocellar space about 3 times as long as distance between ocellus and ipsilateral eye; collar process rounded, not distinct; pronotum smooth, shiny and nearly glabrous (except depression and margin of pronotum with thin setae); anterior half of posterior pronotal lobe with wide shallow longitudinal depression, posterior angle rounded; scutellum with “Y”­shaped carina, apex globular (Fig.1); femora incrassate, fore femora thicker than mid and hind femora, mid and hind femora of nearly same thickness, third tarsomere slightly longer than first and second together; hemelytron extending beyond abdominal tip, discal cell of corium wider than long at base, internal cell of membrane wider than external cell at base; abdomen slightly dilated laterally, ventral surface with transverse wrinkles.
Measurements. Ψ. Body length 13.60–13.70; maximal width abdomen 4.77–4.87. Length head (including neck) 2.35–2.38; length anteocular portion 0.76–0.78; length postocular portion (including neck) 0.97– 1.00; length synthlipsis 0.78–0.80; interocellar space 0.49–0.52; length antennal segments I–IV= 2.18–2.28, 1.40–1.45, 1.47, 1.24; length rostral segments I–III= 1.01–1.11, 1.17–1.19, 0.52–0.57. Length anterior pronotal lobe 1.24–1.35; length posterior pronotal lobe 1.81–1.92; maximal width of thorax 3.47–3.73; length scutellum 0.88–0.98; length hemelytron 8.40–8.51.
Type materials. Holotype, Ψ; China, Sichuan, Chengdu; 21. IV. 1941; H. Y. Swen leg.; kept in NAU; first to third antennal segments, fore and mid tarsi missing. Paratype, 1 Ψ; same collecting place; VI. 1955; collector unknown; kept in CAU; apical two segments of right antenna, and mid legs, missing.
Male: Unknown.
Distribution: China (Sichuan).
Etymology: The species is named after Prof. Lianfang Yang of the Nanjing Agricultural University for her kind support in many ways in our study of Reduviidae.
