INTRODUCTION
Due to theirsmall size, dullcolours, inconspicuous behaviourandhiddenlife
alongseepagesandsmallstreams thatare mostly overgrownby densevegetation
or located in the dark shade offorests, Platystictidae usually escape the atten-
tionof general entomologists and naturalists. Apart fromthefactthatthey are
underrepresented in manyentomological collections, theiroverall similargene-
ralappearanceoftenconcealstheexceptional species diversityandvariationin
minutemorphological structures.
Around 120species fromthe generaDrepanosticta Laidlaw, Platysticta Selys,
ProtostictaSelys, Sulcosticta vanToland SinostictaWilsonhave sofarbeende-
scribedfrom the Oriental region (KALKMAN etal., 2008, VAN TOL, 2009)
andmanynewspecies are stillawaiting description. Mostspecies havevery small
rangesandmanyare islandendemics.As faras southeasternAsiais concerned,
theknowledge ontaxonomy,biogeography andphylogenetic relationships ofthis
extremely interesting familyof forest damselflieshas madeamarkedprogress

only recently, mainly through theworkof J. VAN TOL (2009) andsome other
authors.
SriLanka‘sremarkably diversePlatystictidae wererecognized by someofthe
mostprominentodonatological researchersofthelast 150years.E. deSelys-Long-
champs, H.A. Hagen, W.F.Kirby, F.F. Laidlaw, F.C.FraserandM.A. Lieftinck
describednumerousspecies. Around20 endemicplatystictide taxa are current-
lyknown fromtheisland (FRASER, 1933a, 1933b;LIEFTINCK, 1940, 1955,
1971:BEDJANIC, 2004,2009;BEDJANlC etal„ 2007,2009). Thisdiversity is
impressive,sincethedistributionofallPlaystictidae species is limitedto thewet
andintermediatezones in southwesternand centralparts of SriLanka- inan
areaofonlyca20,000km2.Thus, SriLankacan legitimately beclassifiedas one
of theglobal Platystictidae »hotspots«.
Particularly interesting andremarkableontheglobal scale isthe Drepanostic-
ta speciesradiation, withatotalof 14describedendemicrepresentatives. From
examinationofodonatological collectionsin theNatural History Museums of
Vienna(Austria)andLondon(UK) and,aboveall,the ongoing revisionofthe
abundantPlatystictidae materialin the Entomological Collection atthe Smith-
sonianInstitution, Washington DC, USA (theSmithsonianinsectproject inSri
Lanka: 1969-1975)broughtnewinsights intothe diversityofthisgenus.Together
withthematerialandobservationsmadeduring the author’sexpeditions to Sri
Lankain 1995,2001,2003andtwice in2009, thereis now sufficientknowledge
to make taxonomic descriptions ofthree new species. Revisions of the genera
Drepanosticta andPlatysticta inSriLanka, withdescriptions ofadditionalnew
taxa, determinationkeys and biogeographical andphylogenetic considerations
willfollowinsubsequent papers.
