Emertonella is a genus of cobweb spiders in the family Theridiidae, subfamily Hadrotarsinae, first described by E. B. Bryant in 1945. The genus was re-delimited in 2024 based on male palpal morphology, transferring approximately 30 species from the genus Euryopis. It now contains species distributed across Africa, Asia, Europe, North and South America, and New Guinea.

Euryopis tavara is a small cobweb spider in the family Theridiidae, subfamily Hadrotarsinae. Unlike most theridiids, it does not construct prey-catching webs. The species is known from the United States and shares the genus-wide trait of specialized ant predation. It is one of approximately twenty Euryopis species recorded in North America north of Mexico.
