This unfamiliar squat lobster in the family Chirostylidae was seen a few times while exploring the Northwestern Hawaiian Islands in 2015, but escaped all collection attempts. This particular individual was seen on a black coral at a depth of 1,530 meters (almost 1 mile). Ten years later, it remains undescribed and unnamed.
