Duckworth 1964 mentions that for both species the thorax is white dorsally with brownish black tuft posteriorly but in A. leucillana the apical half of that tuft is brown. BOLD images do not seem to bear out this observation. I did notice, however, that most BOLD images of leucillana show an outwardly angled gray mark on the costal margin at slightly under 1/5 from base followed by an unconnected markt set in from the costal margin at slightly over 1/4 from base. In schlaegeri this coastal mark is never well defined or is absent. When present, it doesn't quite touch the costal margin and is closer to and often often joined to the following mark. If this is a valid identifying mark, then leucillana can be bigger than described as there appear to be larger examples like this in the Guide currently under schlaegeri. - Steve Nanz
