M.fulgidifronssp.n. is described fromGuangxi(holotype$, Shi WanDaShan,
Guangxi, 10-V-1997).The $ ofM.hamiferaLieftinck isdescribed forthefirst time.
M. moorei malayanaLaidlaw and M. hamiferaLieftinck are newly recorded from
Guangxi.
INTRODUCTION
Tenspecimens attributabletothreeMacromiaspecies were captured atShiWan
DaShan,Guangxi inMay 1997.The specimenswereeithercaught by myselforby
Graham Reels.Ofthese, two malesandonefemalebelong toanundescribedspe-
cies, two males andtwo femalesto M. hamifera Lieftinckandthreemales to M.
moorei malayana Laidlaw. The new species is described here and thefemaleof
hamifera, whichwas hithertounknown, is alsodescribed.Asmallfourth species,
probably M. uraniaRis, was observed atShiWanDa Shan,butnot captured. Pre-
viously onlyM. uraniaandM. berlandihavebeenrecordedfrom Guangxi (ZHOU
et al., 1994). The numberofMacromiaspecies nowrecordedfrom Chinatotals
fifteen.TheChinesespecies andtheirdistributionsare listedinTableI.

DISCUSSION. - The closestChinese congenertofulgidifrons appears to be M.
chui (cf. ASAHINA, 1968:94-95, figs 15, 18-22)whichalso has a darkfacewith
abrightyellow postclypeus, asimilarly shaped yellowantehumeralstripe, poorly
developed yellow markingson themaleabdomen,andanangled, strongly keeled,
dorsal carina on thetenthabdominalsegment. The posterior hamulusof chui is
dorso-ventrally broaderthanfulgidifronsandtheinferiorappendage is proportion-
ally longer. ASAH1NA (1968)remarks that:M.chuiisclosely alliedtotheJapanese
and Korean M. daimoji. Ihave examined amale specimen ofM. daimoji, taken
fromAichi Prefecture, Japankindly given tomeby K. Ikeda. Itis acomparatively
larger species with proportionately larger, more robust, posterior hamuliandthe
transverse yellow stripe ofthesecondabdominalsegmentis interrupted laterally.
This latterfeatureisalso sharedwithchui.

LIEFTINCK(1955) consideredthathamifera approached M. amphigena most
closely in detailsofcolouring, armatureoftibiae,and genital organs. The middle

the three describedsubspecies of M. moorei. These includem. mooreiSelys

Laidlaw(Assam, Burma,Thailand, Malaya, Sichuan). ASAHINA (1996) hasre-
