A Field Guide to the Snails of Lord Howe Island

63 Charopella wilkinsoni Animal. Body white with dark grey eyestalks. Key distinguishing features. Small size, bicoloured shell, angulate shell periphery, wide umbilicus and closely spaced ribs. Habitat and occurrence. Most common in the northern part of the island (tracks to North Bay, Kim’s Lookout, Malabar) and on the lower slopes of Intermediate Hill and Mt Lidgbird (Smoking Tree ridge and Boat Harbour tracks). Rarely found on the slopes of Mt Gower. Found living in litter in rainforest and moist woodland. Remarks. This species is similar in size to the introduced Diphyoropa saturni , but can be distinguished by its bicolored shell, angulate periphery and more closely spaced ribs. It can be distinguished from congener Charopella zela by its finer radial ribs and more widely open umbilicus. This species is likely to be heavily under-collected due to its small size and is probably found island- wide.
