This could be an example of EU clarification. One costume, two characters. http://starwars.wikia.com/wiki/Saurin
Two Saurin were at the Mos Eisley Cantina on Tatooine in 0 BBY when Luke Skywalker and Obi-Wan Kenobi came to charter passage off the world.[3] One of the Saurin was Hrchek Kal Fas, a droid trader always on the lookout for cheap droids for sale, even if they were only available on the "invisible market."[32] Although he had come to the desert planet to investigate a possible business relationship with Tatooine's Jawas,[33] he heard news of a reward for two stolen droids, supposedly "close companions" of an Imperial officer. He saw through this cover story, but when he witnessed C-3PO and R2-D2 wander into the cantina, he suspected they might be the droids in question. He tailed them out into the streets of Mos Eisley, but they were nowhere to be seen.[34] The droid trader hired the tall Ranat Nevar Yalnal to do unskilled labor for him.[35] Hrchek Kal Fas also retained the services of his cousin, Sai'torr Kal Fas.[36][37] She was a savvy warrior and combat instructor who took on students she deemed to have the right potential.[38]
Also in 0 BBY, a Saurin was present in the streets of Mos Eisley as the spy Garindan shadowed Luke Skywalker and Obi-Wan Kenobi on their way to Docking Bay 94.[3] Later that year, a Saurin was captured on holofilm in the streets of Mos Eisley and broadcast as part of the Imperial program "Life on Tatooine."[39]
