Etymology. This species name refers to the type locality. Diagnosis. The new species closely resembles P. fulvicornis Chen, 1942. It differs from P. fulvicornis in the elytra with a longitudinal depression at base, aedeagus slender. In P. emeiensis, elytra have a hook-shaped depression at base, and aedeagus robust, 3.1 times longer than wide, parallel-sided in the basal two-thirds, apical third strongly narrowed, apical protrusions nipple-shaped. Tectum long, not reaching the apex of the aedeagus, and truncate at apex. Description. Male: Length: 4.4–5.6 mm, width: 2.2–2.8 mm (mean length 5.2 mm, mean width 2.5 mm, N = 7). General color yellow or yellowish-brown, basal part of inner margin of epipleuron, mesothorax, except mesoepisternum, metathorax and base of first metatarsomere black. Vertex with sparse punctures. Frontal tubercles transverse, extending downward between antenna bases. Antennae slender, 0.9 × as long as body. First antennomere shiny bare, rod-shaped, second to eleventh antennomeres with short hairs, second antennomere shortest, third antennomere 1.8 × as long as second, fourth antennomere about 1.3 × as long as third, fifth to eleventh antennomeres shorter than fourth and gradually shortened. Pronotum about 1.6 × as wide as long, lateral margins slightly curved, basal border slightly convex, apical border slightly concave, disc strongly convex, with dense punctures. Scutellum triangular, smooth, impunctate. Elytra wider than pronotum, humeri convex, disc with dense, minute punctures; and hook-shaped depression behind scutellum. Elytral epipleuron broad at base, continues towards apex. Each tibia with distinct spur at apex, segment 1 of hind tarsi longer than remaining segments combined. Aedeagus robust, with sides slightly rounded, slightly curved at apex in lateral view. Apical protrusions nipple-shaped, small, well separated from each other. Median spiculae with two pairs of slender sclerites, lateral spiculae strongly curved. Female: Length: 4.8–5.8 mm, width: 2.3–3.2 mm (mean length 5.4 mm, mean width 2.6 mm, N = 8). General color yellow or yellowish-brown, scutellum, basal part of inner margin of epipleuron, mesothorax, except mesoepisternum, metathorax and base of first metatarsomere black. Third antennomere about twice as long as second. Elytra lacking longitudinal impression. Spermatheca with big and rounded nodulus, middle part short, and cornu strongly curved. Vaginal palps with wide base and rounded apex, each palp slightly narrowing posteriorly, with 5 setae placed at apex, additional 2 setae subapically. Distribution. China: Sichuan.
