Remarks. Use of this species name has been fairly consistent in the literature. In 1971, Petrushevskaya synonymized Arachnocorys araneosa Haeckel with Arachnocorys circumtexta Haeckel , broadening the concept to include multiple observed morphologies, which differ slightly in size, regularity of the skeleton, and shape of the thorax. The specimens we observed during this study were within the range of those illustrated by previous authors.

Range. Late Miocene—Recent in the EEP ( Table 1 ).
