From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Arlians (アーリア星人, Āria-seijin) are an insect-like race from Planet Arlia.
Dragon Ball Z
All of Moai's guards could shoot laser beams from their mouths and were also swordsmen. They also rode giant Worms. Ironically, the Saiyans were celebrated as heroes by the Arlians, after the two had killed their evil dictator, Moai, and unintentionally freed the oppressed, before they decided that the planet was in too poor of a condition to bring in any profit and vaporized it.
