03D2B512F97A911443E4FBDCFD4C8F81.taxon	diagnosis	Diagnosis. Body 2.60 – 2.70 mm long (mean = 2.65 mm, n = 4); 3.46 – 3.60 × as long as wide (mean = 3.53 ×, n = 4). This species is distinguished by the elytral declivity face strongly shining, striae and interstriae impunctate, indistinguishable; the lower part of declivital face strongly impressed near apex; circumdeclivital margins armed with pointed denticles; declivital face bearing a large triangular spine that is moderately broader at apex than base; elytral apex with an acute spine arising from the sutural interstriae; posterolateral margin of declivity armed with an acute process from interstriae 8. The species is similar to Webbia diversicauda Browne, 1972 but differs by the elytral declivity (W. yinae: acute spine at elytral apex arising from the sutural interstriae, versus W. diversicauda: acute spine at elytral apex arising from the second interstriae, distinctly separated from the suture), and by the much stronger posterolateral process on W. yinae. This species is also similar to W. pabo but differs by the large spine on declivital face (W. yinae: spine triangular, moderately widened from base to apex, versus W. pabo: spine subparallel, as broad at apex as base).	en	Lin, Wei, Li, You, Gao, Lei (2026): A new species of Webbia Hopkins, 1915 (Coleoptera: Curculionidae: Scolytinae: Xyleborini) from China.

03D2B512F97A911443E4FBDCFD4C8F81.taxon	description	Description. Female. 2.60 – 2.70 mm long (mean = 2.65 mm, n = 4); 3.46 – 3.60 × as long as wide (mean = 3.53 ×, n = 4). Bicolored: head, pronotum, elytral apex, declivital face and processes dark brown; antennae, legs and elytral disc pale yellowish brown to brown. Head: epistoma entire, transverse, with a row of hair-like setae, setae long. Frons convex to upper level of eyes; shining, with feebly elevated median line; reticulate, punctate; punctures sparse and fine. Eyes moderately emarginate just above antennal insertion, upper part slightly smaller than lower part. Submentum triangular, deeply impressed. Antennal scape short and thick, slightly longer than club. Pedicel narrower than scape, longer than funicle. Funicle 2 - segmented. Club flattened, circular, as broad as tall, type 2 (Hulcr et al. 2007), segment 1 corneous, corneous portion small, occupying approximately basal 1 / 4 of club, its anterior margin concave on anterior face. Pronotum: 1.27 – 1.33 × as long as wide, the base is slightly narrower than the apex. From dorsal view elongate, near rectangular, type a (Hulcr et al. 2007), sides parallel in basal 3 / 4; anterior margin feebly emarginate medially, anterior margin without serrations. In lateral view elongate, flattened and bulging frontally, type b (Hulcr et al. 2007), disc flat, summit inconspicuous. Anterior slope subshining, with transverse, fine, narrow asperities, becoming lower and smaller towards apical 1 / 3, bearing short, fine, semi-recumbent hair ‒ like setae, setae longest at anterior margin becoming shorter posteriorly and ending at middle of anterior slope; disc subshining, alutaceous, glabrous, moderately densely, finely punctate, punctures with a very short, pale yellowish hair-like seta. Lateral margins weakly carinate. Base feebly bisinuate, posterior angles rounded. Scutellum: not visible from above. Elytra: 2.13 – 2.27 × as long as wide, 1.60 – 1.74 × as long as pronotum. Elytral bases concave, with fringe of mycangial setae extending laterally from the scutellum to striae 3, humeral angles rounded, sides subparallel in basal 4 / 5, then sharply angled to apex. Disc convex, glabrous, shining, subtransparent; striae punctate, punctures moderately sized, separated by about 1 – 2 × their diameter; interstriae flat, glabrous, 3 – 5 × as wide as striae. Declivity abruptly truncate, circumdeclivital margins armed with pointed denticles, each denticle with several long, brownish hair-like setae; the upper part of declivital face flat, not impressed, rather smooth and strongly shining, bearing widely spaced setae; striae and interstriae impunctate, indistinguishable; the lower part of declivital face strongly impressed near apex, rather smooth and strongly shining, impunctate, glabrous at depression; declivital face bearing a large triangular spine at about the lower third of the declivity; the spine is slender at the base but slightly expanded apically, and with two pointed process at its concave apical margin; elytral apex with an acute spine arising from the sutural interstriae; posterolateral margin of declivity armed with an acute process from interstriae 8. Legs: procoxae contiguous. Protibiae slender, broadest at middle; outer margin with 11 small socketed denticles. Mesotibiae flattened, outer margins evenly rounded with 12 small socketed denticles. Metatibiae flattened, outer margins evenly rounded with 12 – 14 small socketed denticles. Male.
