Agorius is a genus of spiders in the family Salticidae (jumping spiders). The genera Agorius and Synagelides (and perhaps Pseudosynagelides) are sometimes separated as a genus group, called subfamily Agoriinae Simon, 1901.[2]


Agorius was first described by Tamerlan Thorell in 1877.[1] No new species were described for about one hundred years, with seven new species found in the twenty-first century. Undescribed species have been found in Malaysia and Sabah.[3] Several more species have been found but not yet described.[4]


Both sexes are about six to eight mm long. Agorius is similar to Myrmarachne, another good ant mimic, but can be distinguished from it by having no large, forward-pointing chelicerae, and is not found on vegetation above the ground, but only in rain forest leaf litter.[3]

A. borneensis, A. formicinus, A. saaristoi and A. semirufus are only known from male specimens; A. cinctus, A. gracilipes and A. marieae are only known from a female.[1]


As of April 2017, there are 12 species in the genus.[1]:
