Notes. Althoughalittledifferentindetails,thesingleknownspecimenofApo-
tomopterus fromMaolan isalmost identicalwithC. (4.) bt,eunlngianus inexternal
morphology. Itis,however,obviouslydifferent fromthelatter inconfigurationof the
malegenitalia,asshowninFigs.4-5 which aredrawn under thesamescale.Notice-
ableisthat thespinulaofmaolanensisnov., theaedeagusofwhich issmallerof the
two, appear larger than that of breunlngianus. Themuch robuster and differently
shapedapical lobeof aedeagus isalsouniqueanddiagnostic.Thesepeculiaritiesare
evidentlyofspecific importance,notsubspecific,even if theexternal featuresof the
beetlesarecloselysimilartoeachother.
