Melitto Melitto were a species of insectile humanoid s native to the planet Li - Toran . They had no eye s or mouth , but were capable of sensing their environment using super - sensitive cilia . Melitto had chitin plates on their heads and forearms , and required the use of breathing tubes when operating in alien atmosphere s . Biology and appearance . With a body comprising a head , a torso , two legs , two arms , and five - fingered hands , the Melitto were humanoid s . Nevertheless , the segmented plates of chitin visible on their heads and hair y forearms betrayed their insectile nature . The Melitto face was covered in four plates , the largest being at the top , but did not feature visible eye s or mouth . However , they did have auditory organs , and the small bristles lining their body were in fact specialized , feathery cilia that could sense vibrations and detect electrical fields . Additionally , those cilia gave the Melitto a keen sense of smell . Their extraordinary scent - memories not only helped them navigate just as well as if they had eyes , but also gave them extensive identification and tracking skills . When operating in atmosphere s different from their own , the Melitto wore breathing tubes and carried dispensers filled with sugar y nutrient fluid . The species had at least two sexes : male and female . One known individual , a male named Sarco Plank , stood 1 . 82 meter s tall . The Melitto language consisted of humming sounds produced by their facial plates . To communicate with other species , they wore vocoders that translated their hums into an understandable voice . Society and culture . Melitto were eusocial beings who lived in hives ruled by queen s and their adolescent female servants — called myrmitrices — who in turn controlled their own stables of male workers — or myrmites — who gathered food , built the physical hive structure , and battled other hives . Whenever a hive ' s population increased too much for it to operate at full efficiency , it became necessary to found a new hive . The myrmitrices then started fighting each other with the help of their warrior followers . When a victor emerged , she gained the right to be queen of a new hive . The myrmites who had the misfortune of surviving their myrmitrix ' s defeat were cast away from their hive , becoming ronin . Most ronin left their homeworld to become expert hunters and thieves . Some , however , were rumored to found their own queenless communities in the subterranean caves of their planet . History . The Melitto evolved on Li - Toran , a dismal and storm - buffeted planet situated in the Inner Rim region of the galaxy . Melitto in the galaxy . In addition to their homeworld , the Melitto also developed a presence on several neighboring planets . However , due to the nature of their society , the Melitto rarely ventured in the wider galaxy , and those who did were mostly ronin . Thanks to their scent - memories , the Melitto made excellent doctor s , capable of detecting chemical components that were markers for diseases . One known Melitto ronin was Sarco Plank , who worked as a bounty hunter , jungle guide , and tomb raider on Devaron during the Galactic Civil War . There , Plank notably dueled the trainee Jedi Luke Skywalker among the ruins of the Temple of Eedit . The encounter left Plank with a near - fatal lightsaber wound . More than three decades later , the ronin had found his way to Niima Outpost on Jakku , where he operated as a scavenger and bounty hunter .
