Abstract PlatycerusrugosusarenewlyrecordedfromChongqingandSichuan,
China, and a new subspecies is described fromShennongjia of western Hubei, under
thenameP.r.jaroslavi.
Platycerus rugosus was originally described by O@J96 (1997, p.11) based on the
specimens collected from Bashan on the Dabashan Mountains in northestern Sichuan
(northernChongqingatpresent)bythelateMr.WakoK>I6L6@>andnativecollectors
under his orders. Since then, no contribution has been made to this species, because
K>I6L6@> unexpectedly passed away in the spring of 1997 without telling any details
aboutthecollectingsiteand/orhabitat.InMarch,2006,Imadeacollectingtripto the
DabaShanMountainsandthenearbyregionswiththeobjectofsurveyingtheplatycer-
inefauna. Thoughunabletofindanyspeciesfromthe type area, I collected a series of
specimensreferabletoO@J96’sspeciesfromMt.GuangtouShanwhichisabout30km
distant to the south from the main ridge of the Daba Shans. In addition to this
discovery, I found the same species from the Micang Shan Mountains of northeastern
Sichuan which was collected as larvae in November 2005 and emerged later in the
laboratory. Furthermore, a male of the same species was collected very recently from
Shennongjia of western Hubei and was submitted to me for study. This specimen is
evidentlydi#erentfromthenominotypicalrugosus,andworth regarded as representing
a new geographical race. In this paper, I am going to record all the specimens of P.
rugosus now in my hands, and describe the Shennongjia one as a new subspecies.
Before going further, I wish to express my sincere thanks to Messrs. Jaroslav
TJGC6 (Czech Republic), Yoshiyuki N6<6=6I6 (Yamagata University), F6C Ting
(International Academic Exchange Center of the Academia Sinica, Chengdu) and
ShigehikoS=>N6@:(OsakaMuseumofNaturalHistory) for their kind help in various
ways. Thanks are also due to Dr. Shun-Ichi U´:CD (National Museum of Nature and
Science, Tokyo) for reading the manuscript of this paper.

Remarks. So far as I have examined the external and aedeagal features, both the
Guangtou Shan and Micang Shan specimens could be identical with or very closely
relatedtothenominotypicalrugosus. Thoughtentativelyregardedasthenominotypical
subspecies, their taxonomic positions should be discussed again taking the endophallic
structure into account. This species is sympatric with P. bashanicus (IBJG6 &
T6C>@69D,1998,p.93;IBJG6,2006a,p.132;idem,2006b,p.138)onMt.Guangtou
Shan, and with P. consimilis phagophilus (IBJG6, 2005, p.260) on the Micang Shan
Mountains. Larvaeprefertofeedonsoftlyrottentwigsofdeciduousbroadleavedtrees

stuck in the ground under fallen leaves on the forest floor. Female leaves peculiar

Remarks. This new subspecies was collected from rather high altitudinal area on
the northeastern slope of the Dashennongjia Massif. In the lower part of the same
mountain range, two other Platycerus species, P. turnai (IBJG6, 2001, p.28) and P.
yeren(idem,2008,p.113)occursympatrically. Ofthese,thelatterwasfirstrecordedas
P. businskyi (IBJG6, 2002, p.38), and later described as an independent species. Our
knowledge is not su$cient as yet whether or not this subspecies occurs sympatrically
