Etymology
The specific name is a matronym honouring Vera Regina Dessimoni von Eickstedt in recognition of her contribution to the taxonomy of ctenids, in particular Phoneutria.
Diagnosis
Phoneutria eickstedtae sp. nov. is most similar to P. nigriventer and P. p e r t y i. Female epigynes have a posterior transverse lobe and the epigynal lateral apophysis has some weak basal sulci (Fig. 16), in contrast to P. nigriventer in which both the posterior transverse lobe and the basal sulci are absent (Fig. 13). In P. p e r t y i, the posterior lobe is ill-defined and the epigynal lateral apophysis has many basal sulci (Fig. 15). Males differ by the wide embolus base (Fig. 39) and the dark brown venter with four series of light yellow dots (Fig 59), whereas in P. nigriventer the embolus base is very narrow (Fig. 36) and the opisthosoma is brown to orange ventrally without lines. In P. pertyi, the embolus base is narrow (Fig. 38) and the opisthosoma is yellowishbrown ventrally with four more conspicuous white lines in the posterior half.
