03F14B34F012190E17CDFA9836C94767.taxon	discussion	Remarks. – This new species is the fourth member of the D. adamsi group which was proposed by Kurosawa (1986), and was first known just before submitting my graduation thesis on the genus Dicronocephalus in 2013. Unfortunately, specimens obtained in the following decade were insufficient. Until last year, this species were collected in large quantities by local people in Yunnan. It is interesting that during my visit in the Oxford University Museum of Natural History in April 2017, two males and one female (Fig. 38 - 44) of this new species were found in a box of flower beetles collected from China by the Scots plant collector George Forrest (1873 - 1932). He had conducted seven expeditions to Yunnan between 1904 and 1932, and sent a large number of plants (including seeds) and animals back to Britain (Luo, 2005). These three individuals captured about one hundred years ago are the earliest known specimens of the species.	en	Qiu, Jian-Yue (2023): Flower beetles of the Asian genus Dicronocephalus Hope (Coleoptera: Scarabaeidae: Cetoniinae): description of a new species from China and intraspecific variations of D. adamsi.

03F14B34F01E190B17EEFDE0347A44CF.taxon	diagnosis	Diagnosis of the male. – Middle to large sized. Body color reddish-brown to black; dorsal and ventral surfaces clad with light gray tomentum. Horns with two forms: 1) horns of large sized individual “ L ” shaped, upwarped vertically from the middle; inner ridge nearly absent; apex with two tips (Fig. 20); 2) horns of small to middle sized individuals much shorter; inner ridge distinct; apex with a single tip (Fig. 21 - 22). Lateral tooth of horn distinct regardless of body size. Clypeal gap small (even with an extremely large body size, Fig. 14, indicated by the blue arrow). Lateral maculae of pronotum absent (Fig. 27 - 29 & 31 - 32) or present (Fig. 23, 25 - 26 & 30). Length of pronotal bands usually 1 / 3 to 4 / 5 of the pronotum length. Scutellum usually partly clad with tomentum (Fig. 23, 28, 30 & 32) or without tomentum (Fig. 25 - 27 & 31). Diagnosis of the female. – Middle sized. Body color dark brown to black. Clypeus “ M ” shaped but anterior margin usually slightly depressed. Elytra gradually narrowed posteriorly from the middle.	en	Qiu, Jian-Yue (2023): Flower beetles of the Asian genus Dicronocephalus Hope (Coleoptera: Scarabaeidae: Cetoniinae): description of a new species from China and intraspecific variations of D. adamsi.

03F14B34F01E190B17EEFDE0347A44CF.taxon	discussion	Variability. – This species is widely distributed fromKorean Peninsula (Kim, 2011) to North Vietnam. Therefore, there are several different geographical populations with different appearances: 1 - Northern population (Fig. 16,30, 32 & 36 - 37, yellow area in Fig. 45), distributed from Yellow River basin to Korean Peninsula with average smallestbody size. Bodycolor usually dark brown to reddish-brown, including the holotype of D. adamsi (Fig. 32); horn in reddish-brown; female with fulvous hairs on pygidium and abdomen (Fig. 16). 2 - Southern population (Fig. 20, 22 - 25, 27 - 28, 31 & 33 - 35, green area in Fig. 45), distributed from Qinling-Daba Mountains to North Vietnam. Body size larger; body color darker, usually black to dark brown, only a very few individuals in reddish-brown; horn in reddish-brown; female with fulvous or black hairs on pygidium and abdomen. 3 - Eastern population (Fig. 15, 21, 26, orange area in Fig. 45), distributed in Eastern China. Average body size the largest; body color the darkest, male and all female black; horn in dark brown or black; female with black hairs on pygidium and abdomen (Fig. 15). 4 - Southwestern population (Fig. 29, purple area in Fig. 45), recently discovered from central Yunnan Province. Body color of male dark brown and most male with tomentum fully covered scutellum (this feature is quite rare in other populations); female black with black hairs on pygidium and abdomen. Remarks. – Legrand (2005) described the subspecies D. a. drumonti, and believed that there were significant differences between it and the nominate subspecies distributed in the Korean Peninsula. Later, Lee et al. (2015) synonymized D a. drumonti with D. a. adamsi based on the phylogenetic analyses and morphological characters. The examination of a lot of specimens confirmed this synonymy, and this species is very common and continuously distributed in the East Asian continent. No specimen of this species was known from southeastern China (i. e., Fujian, Jiangxi, and Guangdong), and the records from Heilongjiang (Zhang et al., 2011) and Mt. Chang Bai Shan, Jilin (Legrand, 2005) are also doubtful (marked with “? ” in Fig. 45).	en	Qiu, Jian-Yue (2023): Flower beetles of the Asian genus Dicronocephalus Hope (Coleoptera: Scarabaeidae: Cetoniinae): description of a new species from China and intraspecific variations of D. adamsi.
