Diagnosis. The males of E. chickeringi Silva, Lise & Carico 2008 resemble those of E. bonaldoi Silva, Lise & Carico 2008 by the shape of the median apophysis (Silva et al. 2008, p. 104, fig. 123), but can be distinguished by the small and laminar dorsal division of the median apophysis (DD) and by the rounded guide (G) of the median apophysis (MA) ( Figs 1, 2 View FIGURES 1 – 6. 1, 2 ).

Palpus with a short dorsal division of the median apophysis (DD) ( Fig. 1 View FIGURES 1 – 6. 1, 2 ). Retrolateral tibial apophysis short and with an acute ectal division (ECD) ( Fig. 2 View FIGURES 1 – 6. 1, 2 ).
