Diagnosis. Males of E. pegasus  sp. nov. are easily recognized by a dorsal apophysis and a retrolateral at the distal border of palpal patella, short RTA outside directed, a great conductor, with tip shaped like Tucano’s beak, TAEB in flap format, flat embolus. Females have the atrium externally shaped like a comma and spermathecae shaped like an inverted wing ( Figs 18View FIGURE 18, 19View FIGURE 19).

Etymology. The specific epithet is a noun taken in apposition and is in reference to Pegasus, in mythology, is a winged horse of Perseus in the ancient Greek, symbol of immortality, and the wings refer to the shape of the female spermathecae.
