Diagnosis: Recognizable by the structure of male genitalia, the dark brown to black antennal segment II with basal 1/5 pale, and the concolorous black posterior lobe of pronotum. Jessopocoris yunnananus similar in overall appearance to J. aterovittatus sp. nov. but can be separated from the latter by the smaller and narrower body, the longer and dense erect setae distributed on the posterior lobe of pronotum, the slender cuneus ( Fig. 6 ), the apical darker coloration of antennal segments II, the longitudinal carina on posterior lobe of pronotum, and the structure of male genitalia ( Figs. 8 , 13–16 ).

Description: Male ( Fig. 3 ): Body small, elongate, hemelytra weakly constricted laterally.

Coloration: Head: Yellow-brown to black-brown, shining; clypeus dark brown; mandibular plate, maxillary plate and buccula pale yellow-brown; labial segments I and II yellow-white, segments III and IV brown, apex of latter segment black-brown; eyes black; antennal segment I yellow, segment II dark brown to black with pale base, segments III and IV black-brown. Thorax: Pronotum black-brown to black, shinning, anterior margin pale yellow brown, calli prominently shining; exposed part of scutellum dark brown with apex paler; clavus black-brown with lateral margin light brown; corium pale yellow, semitransparent, with medial brown to black maculation, in some specimens the maculation extends to lateral margins; embolium pale yellow-white; cuneus brown with inner margin paler; membrane pale infuscate, semitransparent, vein and cell brown; the anterior lobe of pro-pleuron yellow-brown to black-brown, the posterior lobe brown with anterior part paler; meso- and metathoracic pleuron yellow-brown to black-brown; legs pale yellow-white, apex of tarsi brown, claws brown-black; ostiolar peritreme yellow-white. Abdomen: Brown, with transverse dark brown bands on segments.

Vestiture: Dorsum covered with erect or suberect pale brown simple setae; setae of antennal segments II–IV longer than diameter of the segment II, setae of pronotum erect and longer than setae of antennal segment II, abdomen covered with long suberect simple setae.

Structure: Head: Transverse in dorsal view, width 2.5–3.0x its length, nearly vertical; vertex width 2.0–2.2x eye width, without posterior margin carina, weakly punctate excluding median; frons and clypeus slightly convex; mandibular plate broadly triangular; rostrum stout, apex nearly reaching anterior margin of mesocoxa; eyes small, suborbicular in dorsal view; antenna slender, segment I longer than width head, incrassate mesially, diameter at widest point of segment wider than diameter of metatibiae, segment II straight, length 1.9–2.1x segment I length, apex thickened, segments III and IV curved, thinner than segment II, total length 1.3–1.6x segment II length. Thorax: Pronotum campaniform, shining, densely and coarsely punctate excluding calli, anterior lobe narrowed and flattened, anterior margin straight, lateral margin constricted mesially, calli weakly convex, not contingous; posterior lobe strongly prominent, with a narrow longitudinal carina, lateral margins weakly concave at the middle, posteriolateral angles rounded, weakly flattened and tilted dorsally, posterior margin concave at the middle; propleuron bifid, densely and coarsely punctate, lower half of anterior lobe laterally expanded, visible in dorsal view; exposed part of scutellum triangular, sparsely and shallowly punctate, weakly elevated except at apex; hemelytra smooth, flattened in lateral view; clavus broad, with a longitudinal carina extending from base of inner angle to apex of outer margin ( Fig. 6 ); embolium broader mesially; costal fracture inconspicuous, hemelytra weakly deflexed at fracture; cuneus long and narrow, length 2.5–2.8x basal width; membrane prolonged, cell triangular; apex of femur weakly incrassate; tarsi 2-segmented, segment II longer than segment I, apex incrassate; ostiolar peritreme slender.

Male genitalia ( Figs. 8 , 13–16 ): Pygophore brown, covered with suberect pale brown simple setae, length approximately 1/4 of abdomen length, left side of pygophore opening with a small protuberance anterior to base of left paramere ( Fig. 8 ). Aedeagus relatively large, curved ( Fig. 16 ); left paramere curved, posterior arm relatively short, median portion smooth, without protuberance, tapering towards apex, sensory lobe narrow, blunt apically, covered with fairly long hairs ( Figs. 13–15 ), right paramere absent.

Female ( Fig. 4 ): Similar to male in overall appearance but can be larger than males, and overall coloration slightly paler in some specimens, mostly pale with some darker markings.

Distribution. China (Yunnan).

Etymology. The species is named after the type locality.
