GEM. This is a rare species endemic to Tioman Island. I discovered this species before it was described new to science. This particular specimen is an ultra mature huge size specimen which developed an extra thick lip and a yellowish apecture. The normal is white apecture (mouth) and normal size at 10~11mm. This specimen come from my own collection and one of the biggest and best for this species. Unique with lovely yellow apecture. Found alive among leaf litters on forest ground, 23 June 2017. When alive, the animal is blight red. Don't miss this rare opportunity. Only one.
