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 (nl) 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]

Distribution

The specimens mentioned in the original species description all came from Cuba. The holotype was collected in Mensura-Piloto National Park, near Mayarí, Holguín Province. Additional specimens were collected from El Yunque Mountain, near Baracoa, Guantánamo Province and Gran Piedra, Santiago de Cuba Province.[2]

Description

The species has a lemon-yellow colour and the female abdomen lacks humps and is nearly oval. On the spider's back is an ornate pattern halfway between a distorted smiley face and grimace.[2]

Measurements

The male's total length is 2.47–2.66 mm, with a cephalothorax length of 0.74–0.98 mm and femur I length of 1.23–1.90 mm. The female's total length is 2.89–2.40 mm, with a cephalothorax length of 0.91–0.80 mm and a femur I length of 1.75–1.44 mm.[2]

Genetics

Part of the diagnosis of S. berniesandersi includes the combination of four specific mitochondrial DNA nucleotide substitutions.[2]

Etymology

The specific name honors Vermont senator Bernie Sanders, whom the authors describe as "a tireless fighter for human rights and equality, and environmentally aware social democracy".[2] Due to its name, this species received media attention.[5][6][7]
