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 the bare out this observation. I did notice, however, that most BOLD images of leucillana show a dark spot at the anterior bend in the costal margin followed by an unconnected dark spot set in from the coastal margin. In schlaegeri this spot is never well defined or is absent. When present, it doesn't quite touch the coastal margin and is closer to and often often joined to the next spot. 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
