Phellopsis chinensis Semenow 

( Figs. 1View FIGURE 1. A B, 3 C, 4 C, E, 5 A, 6 C, 8 D)

Pseudonosoderma chinense Semenow, 1893: 499  .

Phellopsis chinensis: Champion, 1894: 114  . Reitter, 1916: 131. Gebien, 1936: 668. Masumoto, 1990: 87 –91.

Diagnosis: This species can be distinguished from all other species of Phellopsis  by the absence of the basal stop on the parameres of the male ( Fig. 8View FIGURE 8 D). It can be differentiated externally from P. amurensis  by the rounded to flat elytral humeri ( Figs. 3View FIGURE 3 C, 4 C), elongate and irregular elytral punctures, rugged nature of the elytral ridges ( Fig. 3View FIGURE 3 C, 4 C), and smooth ventral surface of the head, and from P. yulongensis  by the very large tubercles on the ventral body surface ( Fig. 4View FIGURE 4 E) and overall golden scale like vestiture ( Fig. 5View FIGURE 5 A).

Description (male): Length 12.5–21 mm. Robust species; dorsal setose vestiture golden consisting of dense flattened broad scale-like setae ( Fig. 5View FIGURE 5 A); dorsal elytral sculpture very rugged and squarrose.

Head with dorsal surface ( Fig. 6View FIGURE 6 C) with tuberculation almost completely reduced; lateral margin of epistoma anterior to suprantennal ridge long (0.32–0.35 mm); tubercles on ventral surface of head large and flattened creating a relatively smooth surface; gular sutures weakly defined; gula wide, narrowest point near gular pits; subgenal ridge produced apically, rounded margin; subgenal ridge shorter, not extending below eye; eye at same level as gena. Ligula subquadrate with slightly emarginate apical edge.

Pronotal disc between and anterior to lyriform ridges lacking distinct tubercles; paired elevations on apical margin of pronotum distinctly separated along midline; lateral margin of pronotum bisinuate, thickened; hypomeron with very large tubercles, dense intertuberculate setae present; prosternal process slightly biimpressed. Metasternum bituberculate with very large and very small tubercles.

Lateral profile of elytra rounded in dorsal plane; elytral humerus broadly rounded; scutellum rounded; scutellary striole distinct and deep; lateral margin strongly serrate; ridge in 5 th elytral interval starting at or just before metacoxae and extending to mid point of ventrite 3; nodule at apex of elytron slightly smaller to subequal in size to lateral subapical nodule; median subapical nodule larger than lateral and apical ones; paired subapical nodules overlapping for a modest width in the same lateral plane, slightly offset. Tubercles on ventrites large and flattened ( Fig. 4View FIGURE 4 E). Tarsus with ventral setae modified as small spurs, distinctly heavier than dorsal setae.

Aedeagus ( Fig. 8View FIGURE 8 D); ventral surface of parameres broadly arcuate in lateral view, lacking basal stop.

FEMALE: Similar to male but lacking setose pit on submentum.

LARVA: Unknown

Variation: Two specimens from Gansu (1 ɗ, 1 Ψ) have the dorsal elytral sculpture reduced in intensity, and the lateral aspect of the elytra slightly flattened.

Distribution ( Fig. 1View FIGURE 1. A B): Mountains of Central China from the following provinces GANSU, SICHUAN, and SHAANXI.

Recorded distribution: CHINA: GANSU: Min Shan Mts.,h- 2700; 70km W. from Wudu; 15.06.2005.; Leg. A. Gorodinski (3 MAIC. 1 BMNH). Min Shan Range; 70km N.W. Wudu; 1 vi 1997; 2100m; Leg: A. Gorodinski (2 AAPC). Hin Shan Range; 2100m 70km N.W.; Hodo I-VI- 97; Leg.A.Gorodinski (1 AAPC). Min Shan Mts.; 76km N.W. Wudu; 25 vii 2000; Leg: A. Gorodinski (1 AAPC). SICHUAN: Near Pingwu; 1.07.2005.; Leg. A. Gorodinski (3 MAIC). SHAANXI: 100km.S.W. of Xian; Taibai Shan Mt.; Near Houzhezi village; 30.07.2005.; Leg. A. Gorodinski (1 MAIC).

Type: Pseudonosoderma chinense Semenow  HOLOTYPE ɗ in ZIN, missing left protarsus. Hand written on card [in Russian] “pass near village Morpin to south”; 4.VII 85 / folded piece of paper “ 2 -4.811.85”; [in Russian] top of a pass from village of Morpin to the south/ handwritten on graph paper “ Pseudonosoderma chinense  ”; m; typum, unknown character – II- 92 / gold hexagon dot/ red rectangle label “ Holotypus ”/ yellow rectangle “Zoological Institute”; Russian Academy; of Sciences,; St. Petersburg, RUSSIA.

Notes: The specimen identified as P. chinensis  ( HNHM), and assumed to have been examined by Masumoto (1990), does not accurately represent the holotype of P. chinensis Semenow  ( ZIN). That specimen is here designated a paratype of P. yulongensis  NEW SPECIES. The misidentification of P. chinensis  , addition of P. yulongensis  new species, and inclusion of P. imurai  (here synonymized with P. a m u re n s i s) renders the current key to Asian species ( Masumoto 1990) outdated.
