Spintharus berniesandersi is a species of Spintharus ("smiley-faced spiders") in the family Theridiidae. It is endemic to Cuba. It was described in 2018 by Ingi Agnarsson and Lily Sargeant of the University of Vermont in a revision of the genus by Agnarsson and colleagues. S. berniesandersi was discovered alongside 14 other species of smiley-faced spiders.[2] This revision is in contrast to Herbert Walter Levi's taxonomy, which considered it to be intraspecific variation within Spintharus flavidus.[3][4]
