Anelosimus agnar is a species of spider in the family Theridiidae. The holotype and paratype specimens were collected in Teluk Mahkota Johor Malaysia. Both specimens are female; this species currently lack information on males. The spider is named for Agnar Ingólfsson the father of the discoverer Ingi Agnarsson. Females can be identified as members of this species by unusually long and flimsy copulatory ducts. Females range in size from 2.05 to 2.40 millimetres (0.081 to 0.094 in).
