Diagnosis

The holotype female is externally similar to darker specimens in the bipartita group (e.g., E. bipartita ) and flavescens group (e.g., E. lienterica ), but the serrulae of the saw are rather protruding and almost papilliform in E. caucasica compared to more triangular or flat in the bipartita and flavescens groups. The penis valves of the paratype (which may or may not be conspecific with the holotype) are not clearly distinguishable from E. fuscomaculata .
