+belongs to the group I of + +Gibbs +et al. +(1983) + +owing to the presence of two terminal bulbs and a single terminal filament lacking branches* In the identification key proposed by + +Gibbs +et

+differs from these species by: (i) the presence of a group of fusiform bulblets and a separated large oval bulblet in the basal portion of the terminal filament, splitting close to tip (vs* only tiny bulblets present and filament not spliưing); (ii) interbulbar distance 1*3 times distal bulb length (vs* 1*0 times distal bulb length in + +E. australensis + +, 2*8–3*0 times distal bulb length in + +E. austratlanticus + +, and 2*0–7*8 times in + +E. bibulbosus + +); and (iii) length of distal bulb 0*9 times proximal bulb (vs* distal bulb 1*6 times proximal bulb in + +E. australensis + +, distal bulb 1*4–2*1 times proximal bulb in + +E. austratlanticus + +, and distal bulb 1*0–1*6 times proximal bulb in + +E. bibulbosus + +)* Also, it differs from + +E. austratlanticus + +by the longer terminal filament without branches (25*9% SL vs* 10% or shorter, with two short branches near its base), and from + +E. bibulbosus + +by the interbulbar distance 1*2 times proximal bulb length (vs*
