Bernhauer (1934) described D. excellens in the subgenus Leptodiastemus to differentiate between the securiform labial palpi (present in D. bruchi Bernhauer and D. transverserugosus Bernhauer ) and the truncate labial palpi of D. excellens . Leptodiastemus Bernhauer is here placed in synonymy with Xenopygus Bernhauer. However , if the punctatus species group is at some point removed from Xenopygus (see Discussion below) Leptodiastemus would be an appropriate name for these species.
