Kunbir shennongjiaensis sp. nov.

( Figs 1–14 )

Description. Male: Body length: 7.81–12.1 mm (from apical margin of clypeus to abdominal apex), humeral width: 1.70–2.21 mm.

Body with golden-yellow setae. Head black except for maxillary and labial palpi yellow, sometimes occiput reddish brown to blackish brown. Scape and pedicel dark reddish brown, remaining antennomeres light reddish brown; each antennomere with fine pubescence and underside of pedicel and antennomeres III–V with suberect brown setae. Pronotum reddish yellow; scutellum reddish yellow, dark brown on lateral margins, with sparsely pale-yellow pubescence. Elytra reddish yellow, with pale-yellow setae. Ventral surface reddish brown to blackish brown, reddish yellow in prosternum excluding prosternal process reddish brown and ventrites IV–V reddish yellow. Abdomen with sparse silvery pubescence on ventrites I–III except for the middle of apical margins, pubescence more sparsely on ventrites IV–V. Legs reddish yellow, base of pro- and mesotibiae and apex of femora blackish brown; pro- and mesotibiae reddish brown; metafemora clavate and metatibiae piceous black, densely covered with suberect black setae; metafemora pedunculate, sparsely covered with suberect black setae; pro- and mesotarsi reddish brown excluding black apex; metatarsi blackish brown excluding black apex, covered with several fuscous setae on or near apex.

Head moderately projected forwards, slightly narrower than the maximum width of pronotum, occiput irregularly coarsely punctate; frons broad, with a median groove meeting a much deeper, longitudinal groove at its apex; labial terminal palpomere long, narrow; eyes medium-sized and weakly prominent, distance between them 3/7 the width of occiput, which is widely and very deeply emarginate. Antennae longer than body, about 1.06–1.37 times as long as body; scape arched and swollen apically; antennomere III and remaining antennomeres subequal in length: antennomere V longest, antennomere X shortest.

Pronotum slightly longer than its maximum width, lateral margins slightly convergent to posterior margin, with sides rounded just behind anterior margin, moderately arcuate in posterior 3/4, with a pair of small oblique gibbosities just before middle; disc moderately convex though transversely impressed before and behind large median callosity which is interrupted by a pair of deep longitudinal grooves at sides of posterior half, shagreened and gold pubescent except for the smooth callosities, with erected pale-yellow setae. Prosternum almost glabrous though pubescent at sides. Venter of thorax shiny, very sparsely punctate. Meso-and metathorax finely punctate, with dense fine pale pubescence; mesoventral process subquadrate, rather weakly emarginate at sides and apex.

Scutellum trapezoidal, weakly emarginate at apex. Elytra 2.63–3.12 times as long as humeral width, humeri slightly prominent anteriorly, slightly constricted at anterior half and almost parallel-sided in general appearance, apex broadly rounded; disc evenly flattened, densely provided with medium-sized punctures; each elytron with two longitudinal costae, parallel from base to middle, then slightly arcuate to apex. Legs moderately long and slender, metafemora reaching elytral apex, distinctly clavate in apical half; metatibiae about 4/5 the length of metafemora, feebly arched, asperate and with two rows of small dents at external sides; metatarsomere Isubequal in length than metatarsomere II and III combined, metatarsomere III deeply emarginate. Claws divergent.

Abdomen slightly constricted at ventrite III–IV, ventrite Islightly longer than 2/5 the length of abdomen, ventrite II about 1/5 the length of abdomen, ventrite IV shortest and arcuate at apical margin, ventrite Vextending beyond elytral apex.

Male genitalia: ( Figs 8–12 ) Medium-sized and rather lightly sclerotized. Tergite VIII strongly emarginate at apex, bilobed shaped, length about 1.5 times as long as wide, with long setae near apical margin. Sternite VIII bifurcate in transverse semicircle, with sparse short setae. Spiculum gastrale stout. Median lobe about 1/3 the length of abdomen, weakly convex throughout and relatively broadened, with apical lobe swollen, dorsal plate slightly arcuate laterally, median struts 2/5 the length of median lobe, slightly sinuate. Tegmen slender, slightly sinuate in lateral view, about 2/3 the length of median lobe, with prolonged apical part of parameres; parameres 1/3 the length of tegmen, moderately narrowed apically, bilobed, with deep V-shaped concavity at apical margin, and with a few medium-size setae near inner side of each lobe; ring piece about sexangular, provided with long, arcuate dorsal projections at sides of posterior margin.

Female: ( Figs 3–4, 6, 7 ). Body length: 9.12–12.20 mm (measured from apical margin of clypeus to abdominal apex), humeral width 1.80–2.52 mm. Similar to male, but body distinctly broader; antennae shorter than body, antennae about 0.76–0.91 times as long as body. Pronotum about as long as wide, dorsal longitudinal stripe more conspicuous; elytra about 2.80–3.21 times as long as humeral width, almost parallel-sided. Venter of thorax rather coarse, prosternum reddish yellow, weakly prominent behind apical margin; mesoventrite reddish brown and mesoventral process broad, widely and deeply emarginated at apex; metaventrite reddish brown and convex. Abdomen usually reddish yellow; with first segment as long as the following three segments combined; second segment as long as third and fourth combined; second and third segments concave and fringed apically.

Distribution. China: Hubei (Shennongjia).

Habitat. Specimens of Kunbir shennongjiaensis sp. nov. were collected on white flowers of the small tree Photinia beauverdiana Schneid. (Rosaceae) in a sparsely forested and bushy area in Shennongjia Forestry District ( Figs 13 – 15 ).

Phenology. Most of the specimens were collected in middle of May, which likely indicates adult activity at least from middle of April to June.

Etymology. This specific name is derived from the type locality, Shennongjia.

Remarks. This new species is similar to Kunbir simplex Gressitt & Rondon, 1970 (type locality: Laos), Kunbir nomurai Hayashi, 1974 (type locality: Taiwan, China), and Kunbir pilosipes Holzschuh, 2003 (type locality: Shaanxi, China) by the distinctive color of head and body. It can be readily separated from K. simplex by the mesofemora almost entirely yellow and the metafemora clavate black (meso- and metafemora black on apical 3/ 4 in K. simplex ). Also, the new species differs from K. pilosipes by the elytra lacking black macula at apex. From K. nomurai it is differentiated by the mesofemora unicolor. In K. nomurai the mesofemora are yellow on basal half and black on apical half.
