( Figs. 7 , 33–34 , 47 , 60 , 75 , 149–150 , 157, 164 , 171 )

Diagnosis. This species is similar to C. decliva , but the subrectangular clypeus serves to differentiate it ( Figs. 33– 34 ), and scales on the dorsal surface are long and evident ( Fig. 75 ).

Holotype. (male). TL: 22.0 mm, TW: 11.0 mm, CW/CL: 1.23. Head: Black, flat, vertex with a slightly raised longitudinal ridge; with two dark brown, poorly-defined areas located in the basal portion of clypeus; surface densely microsculptured; punctures small, round, or elliptical; few punctures with sparse, radially distributed, long scales. Clypeus subrectangular, anterior margin slightly raised. Gula smooth ( Fig. 34 ). Antenna dark brown. Pronotum: Orange red with a black area on disc and two small, black elliptical maculae near the lateral margins respectively; dorsal surface with numerous setiferous punctures; puctures sparser, larger, deeper on disc; scales long, linear, yellow ( Fig. 75 ); margins smooth, black. Scutellum: Black, with sparse setiferous punctures; scales long, yellow. Elytra: Orange red with humeral umbone, basal and anteromesal portion, sutural costa black; with numerous setiferous punctures, punctures denser and scales longer on postdiscal portion. Sternum: Clad with linear, yellow scales, long and dense on mesosternum and both sides of metasternum. Mesosternal process glabrous, thin, suddenly narrowed in the middle; apex rounded ( Fig. 7 ). Pygidium: Orange red, rugose, with sparse, long, yellow scales. Abdomen: Color gradually from black to orange red; the sternites 2–6 with numerous, linear scales except for medial area; medial area with sparse, setiferous punctures, scales inapparent; last sternite almost glabrous, with a row of yellow setae along posterior margin. Legs: Coxae and trochanters black. Coxae densely clad with linear scales. Trochanters glabrous. Ventral surface of femora orange red with peripheral margins black; covered with short, sinuous striolae and sparse, linear yellow scales. Tibiae orange red with apical portion black; with numerous punctures and sparse, short, yellow scales. Protibia slim, a dark brown spot on the apical portion ( Fig. 47 ); a row of mastoid teeth on ventral surface; deflexed tooth short and blunt ( Fig. 60 ); three teeth along the outer margin of which proximal tooth reduced, the distance between the middle and proximal teeth about 1.3 times the distance between distal and middle teeth; spur very small. Mesotibia and metatibia with a blunt spine in the middle of outer margin; a row of sparse, brush-like, yellow setae along inner margin. Tarsi orange red; apical portion of each tarsomere dark brown ( Fig. 149 ). Protarsus thin; basitarsus slightly clavate. Pretarsi black. Parameres: Elongate, outer margins nearly parallel, proximal part slightly expanded in apical view; apex pointed with a small tuft of straight, golden setae.

Female. Unknown.

Type material. Holotype: CHINA: Yunnan: ♂ (SWUC, ex QCCC, No.542), 21.VII.2002, Gulinqing National Nature Reserve, Maguan County, Wenshan Prefecture, Zhe Li leg.

Etymology. This species is named in honor of the Chinese entomologist Kan-Fan Chen (1904–1981). Chen was a pioneer in the study of Chinese Cicadidae (Insecta: Hemiptera ) from 1933–1981. He worked at the University of Nanking (1933–1957) and at Zhejiang Agricultural University (1957–1975), and collected many of the Cetoniines specimens preserved at NJAU.

Distribution. China: Yunnan.
