Alleles and phylogenetic results

Due to age and indifference I never caught up with the popularity of internet abbreviations such as FTR - no metter how obvious they may be. My brain can't even try to figure them out.
But my comments were of a general nature - i.e. that widespread assumptio that DNA simialrities are not phylogenetically problematic and therefore overide any contradictory morphology. If in your case you had corroborating morphology great. If youa re saying you could not find evnought morphological characters to sort out 60 species and therefore used DNA then fine (assuming you had no incongruence between the two).

FTR, I managed to find a whopping 14 morphological characters for the 60
species I was analyzing in that example.
