AF55B730FFB0FFF1FF3AFE82FC2DFA25.taxon	description	41. Platycerus sepultus Germar, 1837 — Oligocene, Germany 42. Platycerus zherichini Nikolajev, 1990 — Oligocene, Russia Notes on the checklist: As there are numerous discrepancies between our checklist and the latest published catalogue of Palaearctic Coleoptera (Lobl & Smetana 2006), we provided the following explanations for all of the discrepancies. 1. The synonymic list of American species follows Paulsen (2008). 2. According to Paulsen (2005, 2008), Benesh (1946) erroneously used the name Platycerus piceus Kirby, but that name is not available as it is based on a misidentification of Ceruchus piceus (Weber). 3. The synonymic list of European and western Asian species follows Lobl & Smetana (2006). 4. According to Imura (1994 b, 2006 d), Platycerus caerulosus Didier & Seguy is no different from P. caraboides in male genitalia, and it has not been rediscovered in China or even in adjacent areas. The most likely explanation is that the type series was mislabelled from Hunan (Hong-Jang-Hsien). 5. Platycerus chalybaeus MacLeay, Platycerus chlorizans Dalla Torre, and Platycerus coeruleus Dalla Torre were treated as synonyms of Platycerus caucasicus (Parry) by Maes (2008). 6. Platycerus diabolus Dalla Torre and Platycerus nigripes MacLeay were treated as synonyms of Platycerus delagrangei Fairmaire by Maes (2008). 7. Platycerus pseudocaprea Paulus was treated as a valid species by Maes (2008). 8. According to Imura (2007 b), the following three taxa: Platycerus acuticollis takakuwai Fujita, Platycerus acuticollis akitai Fujita, and Platycerus acuticollis namedai Fujita constitute a species independent from Platycerus acuticollis Kurosawa, but the formal revision has not been published yet. 9. Platycerus benesi Imura & Bartolozzi was recently synonymized with Platycerus dundai Imura & Bartolozzi by Imura (2005 c). This species exhibits great individual variation. 10. Platycerus dundai miyatakei Tanikado & Tabana was originally described as a valid species but was subsequently downgraded by Imura (2005 c) as a subspecies of Platycerus dundai Imura & Bartolozzi 11. Platycerus bashanicus Imura & Tanikado was originally described as a subspecies of Platycerus businskyi Imura, but was subsequently given full species rank by Imura (2006 b).	en	Huang, Hao, Chen, Chang-Chin (2009): Notes on the morphology, taxonomy, and natural history of the genus Platycerus Geoffroy from China, with the description of a new species (Coleoptera: Scarabaeoidea: Lucanidae).

AF55B730FFA9FFE8FF3AF9FBFE83FE4B.taxon	diagnosis	Diagnosis. This new species is similar to Platycerus rugosus in most external features (such as male mandible, pronotum, and sclerotized male gentialia), but can be distinguished from the latter by the following combination of characters: dorsal color of males more brown; a ratio of metatarsi length to metatibia length in males being 1.00 – 1.07 versus 1.18 – 1.19 in Platycerus rugosus; a ratio of metatarsi length to metatibia length in females being 0.54 – 0.61 versus 0.67 in Platycerus rugosus; ventrites of males red, not black; incisor teeth closer to molae in male mandible; keels of penis not markedly broader near the proximal end than at other parts; flagellum on endophallus not bifurcate at base; endophallus with one-paired basal pouch and laterodorsal pouches protruded basad as free branches; hemisternite of female genitalia stouter with inner apex not very protruded. In distribution and characters of the pronotum this new species is similar to Platycerus tabanai tabanai and Platycerus tabanai taibaishanensis, but can be easily distinguished from both of them by the following combination of characters: male mandible without a gap between apex and incisor teeth; posterior angle of pronotum sharper in both sexes; basal half of parameres more inflated; keels of penis not much broader near proximal end than at other parts; hemisternite of female genitalia with inner apex not strongly protruding (the characters in endophallus have not been studied for Platycerus tabanai tabanai and Platycerus tabanai taibaishanensis). In distribution and dorsal color of this new species is similar to Platycerus nagahatai, but can be easily distinguished from the latter by the following combination of characters: male mandible without a gap between apex and incisor teeth, with incisor teeth much closer to molae; posterior angle of pronotum angled in both sexes; ventrites of males bright red, not dark black; endophallus with anterior pouch absent, with onepaired basal pouches, one-paired laterodorsal pouches protruding basad as free branches and inflation immediately above ejaculatory area not large; hemisternite of female genitalia with inner apex not strongly protruding.	en	Huang, Hao, Chen, Chang-Chin (2009): Notes on the morphology, taxonomy, and natural history of the genus Platycerus Geoffroy from China, with the description of a new species (Coleoptera: Scarabaeoidea: Lucanidae).

AF55B730FFA9FFE8FF3AF9FBFE83FE4B.taxon	discussion	Discussion. An uncertainty is that the male specimens identified as Platycerus rugosus in this work were not collected from the type locality, the Dabashan Mountains. Instead, they were collected from the Micangshan Mountains, which are the western extension of the Dabashan Mountains and possess very similar fauna; however they match the original description of Platycerus rugosus in all the diagnostic characters, including the sclerotized male genitalia. The only problem is that the endophallus of Platycerus rugosus has not been studied for specimens from the type locality. Nevertheless, Platycerus yingqii can be easily distinguished from Platycerus rugosus at least by those characters in external features, the sclerotized male genitalia, and female genitalia. Both Platycerus tabanai and Platycerus tabanai taibaishanensis were described from the same area in Qinling Mountains and based on male specimens as holotypes; they are somewhat similar to the new species in some characters, but can be distinguished by several important characters as stated in " diagnosis ". There is detailed information on the characters of the male mandible and the sclerotized male genitalia in the literature for both Platycerus tabanai and Platycerus tabanai taibaishanensis. The relationship between Platycerus tabanai tabanai and Platycerus tabanai taibaishanensis needs an examination of more specimens and characters in endophallus; however this has nothing to do with the validity of Platycerus yingqii.	en	Huang, Hao, Chen, Chang-Chin (2009): Notes on the morphology, taxonomy, and natural history of the genus Platycerus Geoffroy from China, with the description of a new species (Coleoptera: Scarabaeoidea: Lucanidae).
