Introduction
CalicnemiaStrand,1928isaspeciosegenusinSoutheastAsia,India,andChina.Accordingto
Lieftinck(1984)thisgenuscanbedividedintotwogroupsbasedonthestructureofthepenile
organ. Group I has the penile lobe terminating in long, curved, ribbon-like filaments (type I)
whereasgroupIIhasashort,broader,shield-likepenilelobewithoutfilaments(typeII).During
thefirstdecadeofthetwenty-firstcentury,fivenewspeciesofCalicnemiahavebeendescribed

Habitat
Found in a montane stream at about 1000–1300m, no more than 50m away from a waterfall.
Also occurring in the same area are Calicnemia eximia, the amphipterygid Devadatta ducatrix
Lieftinck,1969andthemegapodagrionidAgriomorphafuscaMay,1933.
Discussion
Calicnemia soccifera resembles C. erythromelas in its body colors, but differs in the shape of
the penile organ and caudal appendages. The penile lobe (Figure 1i) of C. soccifera is typical
of type II species (Lieftinck, 1984) whereas that of C. erythromelas belongs to type I, since it
isdividedintoapairofshorter,broadlyribbon-likeprocessesseparatedbyaV-shapedincision
(cf. Lieftinck, 1977, p. 23, figure 15). Cerci of C. erythromelas bear very strongly developed
middleteeth(cf.Lieftinck,1977,p.23,figures16–17;Yu&Bu,2008,p.249,figures1–3)that
are longer than in C. soccifera (Figure 1f). In addition C. soccifera lacks a distinct broad pale
stripe on the top of its head. The body color pattern of C. soccifera somewhat resembles also
that of C. uenoiAsahina, 1997 fromVietnam, but in C. uenoi the shape of caudal appendages
is very different, with only a short middle tooth on each cercus (cf. Asahina, 1997, p. 21,
figure15).
With the exception of C. erythromelas, C. eximia, and C. sinensis, the Chinese Calicnemia
speciesbelongtotheGroupIIintheclassificationbyLieftinck(1984).Alltherecentlydescribed
species (C. chaoi, C. haksik, C. gulinensis, C. porcata, C. zhuae and the present C. soccifera)
belongtothisgroup,allofwhichhavebroaderandshield-likepenilelobeswithoutfilaments,as
inC.miles(cf.Lieftinck,1977,p.21,figure12).Someofthesespeciesseemtobecloselyrelated,
andmoredetailedstudiesareneededtoclarifytheirtruerelationships.YuandBu(2008)pointed
outthattheonlypublishedrecordofC.miniatafromChinabySuiandSun(1984)infactrefers
toC.sinensis.ThereforetheoccurrenceofC.miniatainChinaremainedquestionable.However,
recently,thefirstauthor(XY)foundoneunidentifiedmalespecimen(Motuo,Xizang[Tibet],1
July1983,altitude850m,leg.YinhengHan)fromtheInstituteofZoology,ChineseAcademyof
Sciences, Beijing, which belongs to C. miniata.Therefore, C. miniata is confirmed to occur in
China.
