Variation. In both sexes, the shape and size of maculae on pronotum, elytra, and postprosternum vary considerably; color patterns (Figs. 21, 27–37) are presented in the plate as comprehensively as is possible. The predominant patterns are shown in Figs. 21, 27–32, are found on individuals from various places in southern China, such as north Guangdong (Mount Nanling), north Fujian (Mount Wuyishan), and south Guangxi (Mount Shiwandashan). Individuals (Figs. 33–34) were found in Mount Jinyunshan, Chongqing, and other specimens with black area on pronotum were found in Fujian, Hainan Island, and Laos (Fig. 35). The specimen (Fig. 36) closely resembling the holotype of Clinterocera vitalisi (Bourgoin, 1924) (Fig. 19) was collected at Jingxi, Gunagxi. The entirely black form was found at Mount Nanling, Guangdong and Mount Leigongshan, Guizhou, China (Fig. 37).

Comments on type locality. The type locality of Clinterocera discipennis, Nyenhangli, eg. Yuankengli (Kffi ffl/ aeffiffl), or Nyenhang (Yuankeng Kffi/ aeffi), is a small village (near 23°48'11''N, 115°27'30''E) in Changbu, Wuhua, Meizhou, Guangdong province, and a chapel and a missionary residence of the Basel Mission was established by missionary Charles Piton in 1866 (Lutz & Lutz 1995; Lamarre 2002; Tiedemann 2009). Nyenhangli is also the type locality of Pyrestes quinquesignata Fairmaire, 1889 (Coleoptera: Cerambycidae), Spilopopillia sexmaculata Kraatz, 1892 (Coleoptera: Scarabaeidae), and Coraebus larminati Kubáň, 1995 (Coleoptera: Buprestidae) (Fairmaire 1889; Kraatz 1892; Kubáň 1995). The type locality of Callynomes rufithorax and C. cruciata, Montes-Mauson, is Mount Mẫu SƠn, located in Lạng SƠn, Vietnam, near the border between Guangxi, China and Vietnam. According to the original publication (Fairmaire 1904), the type specimen of Clinterocera rufiventris was collected from border of Laos, which far from the locality (Dong Van, Vietnam) in the “ type ” labels.

Natural history. Clinterocera discipennis is not very rare, and inhabits various landscapes, such as karst topography, meadows, and bushes in subtropical humid forest (Figs. 101–104). But its natural history is still unknown. Adults are occasionally observed moving on the ground, and some crushed individuals were found near pathway and road. The living female from Jingxi County, Guangxi was transferred to a box within rotten wood in laboratory, but oviposition and feeding behaviors were not observed before it died (Fig. 105).
Remarks. Clinterocera discipennis is widely distributed in southern China, northern Vietnam, and northern Laos. Smetana (2006) listed this species from Anhui province, but we know of no specimen with reliable collecting data to confirm this record, perhaps indicating that the record is a misinterpretation of an old locality name. The record from Mount Tianmushan in Zhejiang province reported by Ma (2001) was accepted and presented in the distribution map because this species is usually not difficult to recognize.
Although the holotype for Clinterocera discipennis Fairmaire, 1889 was not found, we still could recognize the elytral pattern of the type specimen similar to Fig. 21 from the original description (Fairmaire 1889). Due to the considerable variation in color patterns on elytra and pronotum, C. discipennis is easily identified as different species based on insufficient specimens. Sakai & Nagai (1998) considered the color patterns in Figs. 27 and 31 as C. discipennis (Fairmaire, 1889) and C. rufithorax (Moser, 1901), respectively. A specimen with a black band on its pronotum was first described by Sakai (2008) from Laos and he identified it as C. rufithorax (Moser, 1901); the pattern similar to Fig. 35 but black on anteapical umbone of elytra, and we a similar specimen from Mount Wuyishan, Fujian. Paulian (1961) was aware of the color variations in this species, and indicated C. cruciata (Moser, 1901) as a variety of C. rufithorax (Moser, 1901). Ma (1992; 1993b; 1995; 2004) also regarded three patterns (Figs. 21, 27, 31) as C. discipennis, although no taxonomic action on this issue was taken in her works. Li (2004) recorded a specimen from Mount Wuzhishan on Hainan Island, with the elytral pattern given in Fig. 28, and we examined a female similar to Fig.21 from the same locality. A male specimen (Fig. 36) from Jingxi County of Guangxi province was identified as C. vitalisi (Bourgoin, 1924) by Sasaki (2007), which has the same pattern as the holotype (Fig. 19), but a specimen with a different elytral pattern was collected by author (QIU) from nearby place (Fig. 105). The continuous variations of coloration patterns (Figs. 21–37) are displayed by these specimens occur sympatrically, and this is why we propose regard C. rufithorax (Moser, 1901), C. cruciata (Moser, 1901), C. rufiventris (Fairmaire, 1904), and C. vitalisi (Bourgoin, 1924) as junior synonyms of C. discipennis Fairmaire, 1889.
The mysterious species, Clinterocera rubra Ma, 1992, was discovered from Mount Mangshan National Nature Reserve in Hunan where nearby Mount Nanling National Nature Reserve of Guangdong (Ma 1992). The female holotype was examined in IZAS in February 2012; it resembles C. discipennis, but the body is completely red, and each side of the pronotum has an unclear macula. No more specimens was found since the species was described, hence this rare species is only listed in several catalogues (Krajčík 1999, 2011, 2012a; Smetana 2006). Fortunately, we found two conspecific male specimens in HFCS (Figs. 38–42), bearing the same collecting data as the holotype. Apparently these two specimens were collected together with holotype, but were omitted when Ma (1992) was preparing the Cetoniinae fauna of Hunan province. After careful comparison, we believe that they were collected immediately after emergence from the pupa in rotten wood, since the body of newly emerged beetles is usually red, the integument being flexible, and without maculae. Consequently, Clinterocera rubra Ma, 1992 is also regarded as a junior synonym of C. discipennis (Fairmaire, 1889).
