Anelosimus oritoyacu is a species of tangle-web spider found in Ecuador and Mexico at altitudes from 1800 to 2000 metres (5900 to 6600 ft). It is subsocial although it has some features which distinguish it from other social or subsocial spiders in the genus. It has long-lived nest sites unlike the social spider Anelosimus eximius which has more transitory nest sites and its webs do not have aerial threads found in other social and sub-social species.
