Steindachner's emo skink, Micronesian skink, dark-sided emoia, dark-sided skink, or dateline emoia (Emoia adspersa) is a species of lizard in the family Scincidae. It is found in Micronesia.[1][2] The species has also been noted to occur on Niuafoʻou, the northernmost island of Tonga, with sightings in 1930 and 1994.[3] The species is not present on other Tongan islands, and is possibly present due to waif dispersal occurring during Polynesian migration.[4]
