Spilogona changbaishanensis ps.nov.(figs.l-3)Male:Closely related to the Northern European species Spilogona tri-anguligera(Zetterstedt,1838)in general features.But the width of frons in male fairly narrow;free part of anal cereal plate triangular,the branches of which rather short;the fore margin of anal cercus in profile with a wavy outline instead of more regularly curvature as in S.trianguligera.The type specimen is deposited in the Benxi Anti-Epidemic Station,Liaoning Province.
