The members of this genus are very poorly IDed by the computer vision. I'm not sure if flagging is the proper course of action here, I'm following the example of this forum post: https://forum.inaturalist.org/t/computer-vision-clean-up-wiki/7281

Immature individuals of the two species are not possible to ID to the species level. Only photos of adults in which the color of the thickened outer lip of the shell is clearly visible, are able to be ID-ed correctly.

Unless someone has dissected out the love dart, and photographed the cross-section of that structure, but love darts would only be present in an adult anyway.
