@Feral, there are various species from the genus Cubaris that have yet to be identified to the species level, hence the crazy placeholder common names.
This is Cubaris sp. "Jupiter", but there are Cubaris sp. "Red Edge", Cubaris sp. "Rubber Ducky", Cubaris sp. "White Ducky", Cubaris sp. "Cliff Ducky", Cubaris sp. "Laser", and so for about 50 other varieties and species probably.
Yup, I totally thought RD was just a regular common name, not an actual real placeholder name for an undescribed species. And I had no idea about the others in that genus. So yes excellent, thanks for the learning/great info!
