Intermediate forms to these show lines of spots joined together to compose transverse wave-like bands across the entire surface.

has so far been recorded only throughout the southern spring (late September to early December) and in early autumn (April) and, like in its sister species, the life cycle seems to be linked to fine sandy substrata, on the banks of rivers and streams. All specimens collected recently in the Komsberg were retrieved from the same farm trough adjacent to a dry river bed exhibiting substantial sand banks (D. Clark, pers. comm.). A few old specimens also carry unmistakable clues that they were found along river beds (cf. label data above).
