Actinocyclus papillatus from eastern Australia

August 4, 2005
From: Bill Rudman

I previously had this species on the Forum as a form of Actinocyclus japonicus but following Valdes's (2002)  review, I guess this should be identified as Actinocyclus papillatus.

Locality: Coffs Harbour region, nothern New South Wales, December 1990. Photos: Bill Rudman [more detail to be added]

It fits his description of that species in having a very tuberculate mantle. Valdes also describes 'a number of short, irregular, very densely arranged dark grey lines ...' and ' numerous white spots'. While the white spots are very obvious, the lines are not so clear. If you look carefully at the lower right close-up, the spots do appear to be arranged in lines, which gives the intervening space the appearance of dark lines.  The photo in Valdes (2002) is of an animal with much more white pigmentation.

Best wishes
