The sole representativeof thegenus Lipromopha CHUJoet KIMoTo, 1960 in
JapanhasbeenL difficili.s・1ooc11ooanaCHuJo, l961, fromtheRyukyuArchipelago.It
wasfirstdescribedfromAmami-0shimaIsasasubspeciesofL dがi cillsCHEN,1934,
then synonymized with it by KIMoTo (1965). By comparing specimens from the
RyukyupopulationcarefullywiththoseofTaiwan,theauthorcametotheconclusion
thattheformer isclearlyseparable fromthelatterandshouldberegardedasagood
species.Inaddition,asecondmemberofthegenuswasfoundinthesouthernRyukyu

AspointedoutbyCHUJo(1961)inhisoriginaldescription,theJapanesepopula-
tionisclearlydistinguishable fromtheTaiwanese.Themainpointsofdiscrimination
areas follows:
1. Bodycolorationispitchybrownwithantennae,tibiaeandtarsimuchpaler.In
contrast,theTaiwanesepopulationislightyellowishbrownwithhead,pronotumand
basalportionofelytradarker.
