Abstract AnewspeciesofthegenusPlatycerusisdescribedfromMt.Fanjing
ShaninnortheasternGuizhou,SouthChina,underthenameP.mandibularis.Thisis
thefirstrecordofthegenusfromGuizhouProvince.
Uptothepresent,noPlatyceruslucanidbeetles have been recorded from Guizhou
ProvinceinSouthChina. Veryrecently,Ihadan opportunity to make a faunal survey
on Mt. Fanjing Shan in the northeastern part of the province, and succeeded in
collecting a long series of the Platycerus specimens. Though considerably variable in
dorsalcoloration,aboveallinthemale,theseriesiscomposedofasinglespeciesand is
consideredtobenewtoscience. Inthefollowinglines,Iamgoingtodescribeitasanew
speciesunderthenameofPlatycerusmandibularis. Accordingtothepresentdiscovery,
distributionalrangeofthegenusPlatycerusinChinanowextendsoverthefollowingten
administrative districts: Liaoning, Neimenggu, Zhejiang, Henan, Hubei, Shaanxi,
Chongqing, Sichuan, Yunnan and Guizhou (IBJG6, 2006b; IBJG6 & W6C, 2006,
etc.).
Before going into further details, I wish to express my heartfelt thanks to Messrs.
F6CTing(InternationalAcademicExchangeCenteroftheAcademiaSinica,Chengdu)
and Y6D Guang-Lie (Academia Sinica, Guiyang) for their kind aid through my field
works, to Mr. Yoshiyuki N6<6=6I6 (Yamagata University) for his help in various
ways, and to Dr. Shun-Ichi U´:CD (National Museum of Nature and Science, Tokyo)
for reviewing the manuscript of this paper.
Platycerus mandibularis IBJG6, sp. nov.
(Figs.1(cid:1)8)
Male. Length (including mandibles): 11.5(cid:1)13.3mm. Dorsal surface strongly
polished, with the coloration yellow- to reddish coppery partly with a faint orange- or
purplish tinge, or yellowish brassy with a greenish tinge; venter of head including
mandibles brownish black with a strong yellow-greenish tinge, that of pronotum and
mesosternum almost black partly with a faint greenish tinge, metasterna yellowish
brownwitharemarkable greenish tinge, abdominal sternites reddish brown; mandibles

apical tips, tibiae a little more red-brownish with the proximal parts brownish black,
tarsi and claws brown though usually a little darker in basal part of each segment.
Most closely allied to P. feminatus T6C>@69D et T676C6 (1997) described from
MeiguXianofsouth-centralSichuan,butreadilydiscriminatedfromthatspeciesmainly
by peculiarly shaped mandibles and genital organ. The new species di#ers from P.
feminatus in the following respects: 1) coloration of legs di#erent, areas around each
knee joint brownish black in the new species, while they are much less dark in P.
feminatus; 2) mandibles much more strongly developed, large, stout and remarkably
elongated for a member of the genus, with the outer margins almost straight at basal
three-fourths and faintly emarginate at the middle, acutely hooked inwards at apical
fourth, then gradually tapered towards apices which are sharply pointed and obviously
reflexed above in lateral view; 3) dorsal surface of mandibles widely depressed, with a
large hump near the base; 4) retinacula large and longitudinally elongated, their inner
margins multi-dentate, with four to eight small teeth on each side; 5) pronotum more
strongly convex above, with the lateral sides roundly arcuate and not angulate at the
basal third as in P. feminatus. Male genital organ basically similar to that of P.
feminatus, but definitely di#erent from that of the latter race in having the following
characteristics: 1) paramere longer and slenderer, with the apico-ventral corner in
lateralviewlessremarkablyangulatethaninP.feminatus;2)terminalplatesofaedeagus
shorterandmoretransverse,withthedistalendofeachplatenotsostronglyprotruded
as in P. feminatus; 3) endophallus larger and robuster, above all in the apical portion,
withapairoffinger-likeprotrusionsat each side of flagellum more strongly developed.
Female. Length (including mandibles): 10.5(cid:1)12.6mm. Body above strongly
polished,goldencopperytobrassyusuallywitharemarkablegreenishtinge;venterand
appendagesalmostasinmale,thoughfemoraarealittlemorestronglydarkreddishand
abdominal sternites are a little more brownish.
AlsocloselyalliedtoP.feminatus,andbarelydistinguishablefromthatraceinthe
followingrespects:1)areasaroundeachkneejointdarkerincoloration;2)pronotuma
little more strongly convex above, with the lateral margins roundly arcuate and hardly
angulate at the basal third; 3) shoulders usually a little less prominent; 4) gonocoxite
with the lateral sides not subparallel-sided as in P. feminatus but apparently narrowed
towards apex, with the inner margin rather remarkably sinuate.

Notes. Before the discovery of the present new species, no Platycerus has been
known from Guizhou Province. Though distinguishable at a glance from P. feminatus
byhavingmuchlargermandibles,thisnewspeciesisacloserelativeofthelatterbeyond
doubt. This is readily understood from a very close similarity of their aedeagi and
endophalli. Thesetwospeciesshouldbelongtothesamelineageasthat constructed by
P. cupreimicans IBJG6 (2006 a), P. dundai IBJG6 et B6GIDADOO> (1994), P. ladyae
IBJG6(2005)andP.tabanaiT6C>@69DetO@J96(1994),whosedistributionisrather
widelyrangedfromnorthwesternYunnantosouthernShaanxialongthewesternmargin
oftheSichuanBasin,thoughthelocalityofthenewspecies,FanjingShan,iscompletely
isolated from all the known collecting sites of this group.
The new species was collected from the mixed forest of evergreen oak trees and
deciduous broadleaved trees such as Fagus, Acer, Carpinus, Prunus, etc., now widely
preservedintheupperpartofMt.FanjingShan.Allthe type specimens were hibernat-
