Jessopocoris aterovittatus sp. nov.

( Figs. 1, 2 , 5 , 7 , 9–12 )

Type specimens: Holotype: male, CHINA: Longsheng Ethnic Autonomous County (25°50'N, 110°1'E), Guilin City, Guangxi Province, 28. VIII. 1964, Liang-chen Wang leg. Paratypes: 2 males, 3 females, same data as holotype; 1 male, 3 females, same data as above, Sheng-li Liu leg.

Diagnosis: Recognized by the short, semirecumbent and curved setae on pronotum, the yellow mediolongitudinal carina on the posterior lobe of pronotum, and completely yellow to yellow-brown antennal segments. Jessopocoris aterovittatus is most similar in appearance to J. scutellatus , but distinguished from the latter by the total length of antennal segments III and IV being 2.1x shorter than segment II, and the concolorous anterior lobe of pronotum.

Description: Male ( Fig. 1 ): Body small, elongate, hemelytra weakly constricted laterally.

Coloration: Head: black brown to reddish brown, shinning; clypeus dark brown; mandibular plate, maxillary plate and buccula yellow-brown; labial segments I and II yellow, segments III and IV brown, apex black-brown; eyes black; antennal segments I and II pale yellow, the latter darker at apex, segments III and IV dark brown. Thorax: Pronotum black-brown, shining, anterior margin pale yellow-brown; calli shining; yellow longitudinal carina along median of posterior lobe; exposed part of scutellum yellow-brown with apex paler; clavus blackbrown, paler at middle of outer portion; corium pale yellow, semitransparent, with medial brown maculation extending to lateralmargin of hemelytra; embolium yellow; cuneus brown with interior margin relatively pale; membrane pale infuscate, semitransparent, vein and cell brown; propleuron brown, anterior portion of posterior lobe light brown; meso- and metathoracic pleuron yellow-brown to black-brown; legs pale yellow, apex of tarsi brown, claw black-brown; ostiolar peritreme yellow-white. Abdomen: Brown, with transverse dark brown bands on segments.

Vestiture: Dorsum covered with suberect pale brown simple setae; setae of antennal segments II–IV longer than diameter of segment II, the setae of the pronotum semirecumbent, curved and shorter than the setae on antennal segment II, and abdomen covered with recumbent simple setae.

Structure: Head: Transverse in dorsal view, width 3.3–4.0x its length, nearly vertical; vertex width 2.1–2.5x eye width, without posterior margin carina, weakly punctate excluding smooth median; frons and clypeus weakly convex in lateral view, clypeus not visible from above; mandibular plate broadly triangular, weakly convex; rostrum stout, apex nearly reaching anterior margin of mesocoxa; eyes small, suborbicular in dorsal view; antenna slender, length segment I greater than the width head, segment I incrassate in the middle, diameter at widest point greater than diameter of metatibiae, segment II straight, length segment II 2.1–2.4x segment I, width equal to the base of segment I, apex weakly thicker, segments III and IV curved, thinner than segment II, total length 1.3–1.5x segment II length. Thorax: Pronotum campaniform, shining, densely and coarsely punctate except for impunctate calli, anterior lobe narrowed and flattened, anterior margin straight, lateral margin constricted mesially, calli slightly convex and not contingous; posterior lobe prominent, with a narrow longitudinal carina, posteriolateral angles rounded, weakly flattened and tilted dorsally, posterior margin medially concave; 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 the 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. 5 ); embolium weakly broader mesially; costal fracture inconspicuous, hemelytra weakly deflexed at fracture; cuneus long and narrow, length 1.7–2.1x basal width; membrane prolonged, cell triangular; apex of femur slightly incrassate; tarsi 2-segmented, segment II longer than segment I, apex incrassate; ostiolar peritreme slender.

Male genitalia ( Figs. 7 , 9–12 ): Pygophore brown, covered with suberect pale brown simple setae, length approximately 1/6 of abdomen length, left side of pygophore opening with a small protuberance anterior to base of left paramere ( Fig. 7 ). Aedeagus relatively small ( Fig. 12 ); left paramere large, curved, posterior arm extended, with one protuberance mesially, apex sharp, sensory lobe broad, blunt apically, covered with long hairs ( Figs. 9– 11 ); right paramere absent.

Female ( Fig. 2 ): Body surface and coloration similar to male; cuneus smaller and narrower than male.

Distribution. China (Guangxi).

Etymology. Named for the transverse black band in the middle of hemelytra.
