Abstract A new subspeciesofPlatycerushongwotlpyot isdescribedfromMt
TianmuShanofnorthernZhejiang,EastChina,underthenameP h tianmushanus.
Platycerushongwonpyoi IMURAetCHoE(1989,p.20) isoneoftherepresentative
speciesofplatycerinelucanidbeetlesoccurringinEastAsia,whichisratherwidelybut
sporadicallydistributedfromtheKoreanPeninsulatoCentralChina. Thenominotypi-
ca1subspecieswasdescribed fromtheChiri-sanMountainslyinginthesouthernmost
part of the Korean Peninsula and is rather widely distributed in South Korea
(WATANABE, l989; IMURA,1993). ThepopulationdistributedfromNorth Koreato
northeasternChinaisrepresentedbysubsp merkli (IMURA&CHoE,1989,p 21; LI,
1997, p 43; IMuRA, 2006b, p 24). Thespecies isalsoknown fromthecentraland
northern partsof Chinaand thepopulation distributed in thoseareais classified into
foursubspecies. Thus, totallysixsubspecieshavebeendescribeduptothepresentas

Notes. Trueaffinityofsubsp tianmushanusinall theknown racesofPlatycerus
hongw,onpyoi isnotcertainat thepresentmoment, but it isworthnotingthatsuchan
isolated population of the same species occurs at the eastern end of the Chinese
Continent near theEastChinaSea,andthediscoveryof thepresentnewsubspecies
posesan interestingproblemto therelationshipbetween thegeohistorica1background
andprocessof dispersal of thePlatycerusspeciesinEast Asia.
