INTRODUCTION
is a widespread genuswith numerousOld World species. Of the
fewPhilippine Pseudagrion species, thereddishandblack P.pilidorsum (Brauer,
1868)is undoubtedly oneofthe mostdominantand widespread damselfliesinthe
archipelago.
Recent material, gathered by thepresent author, revealedthat an undescribed
reddishandblackPseudagrion species occurs intheinteriormountainsofMindanao.
Itisdescribedhere,mainly bymeansofcomparison withP.pilidorsum. So far, the
newspecies hasbeen foundat8 sites; attwoofthemtogether withP.pilidorsum.
The new speciesisnamed afterAlex Buenafe(Negros,the Philippines),who has collected for
me andaccompanied mein field duringmany years. He has discovered manydragonflynovelties in
various islands.

DISCUSSION
BesidesP.pilidorsum andP. buenafeisp.n., anumberofotherPseudagrion spe-
cies occur in the Philippines. SELYS LONGCHAMPS (1882) introduced P.
microcephalum (Rambur, 1842) andP. crocops Selys, 1876as Philippine species.
The former has proven to be a widespread, although uncommon species in the
Philippines, butthe occurrence oftheCelebesianP. crocopsinthePhilippines has
remainedunconfirmed, andthesingle specimen (“un exemplaire indique des lies
Philippines”) may represent amislabelledspecimen. P. crocops iseasy torecog-
nizeby itsbrightlyyellowishlabrumandfrons.AlsotheSELYSLONGCHAMPS’s
(1891) recordofa female P. decorum(Rambur, 1842)from the Philippines un-
doubtedly refers to a misidentifiedspecies. NEEDHAM & GYGER (1939) de-
scribedthree newspecies, P. azureum, P.evanidumandP.flavifrons,fromLuzon.
However,thelatterappearstobe asynonym ofP. rubriceps Selys, 1876.
