Two locality variations:
Yellow var. - Marigold yellow. The black segment spotting makes the yellow morph pop even more, giving it that high-contrast, almost “candy lacquered” look.
Chestnut var. - Deep rusty maroon coloration. The darker morph looks like a burnt sienna / rusty chestnut — it has that deep reddish-brown tone with a warm undertone, almost like oxidized iron or polished mahogany.
Unsubscribed species, If I could name this species I would call it: Candy Colored Slug, Fatalatus badassnus. Native to South Sulawesi. Bright, FAT, Shiny & BEAUTIFUL! Nuff Said...
