Eurycyphon aquilus Watts, 2011

( Fig. 51 )

Material studied. 2♂ Vic, Cement Creek beating vegetation 2/2/08 CHS Watts ( SAMA, PZ).

Male ( Fig. 51 ). The base of the tegmen is more rounded than in the relatives. The parameres are distally not convoluted but divided into a ventral and a dorsal branch. Each ventral branch ends in an approximately triangular sclerite which is directed mediad and opposed to its counterpart. The dorsal branch is longer and ends in an elongate plate which in oblique view is seen to have a ventrally bulging serrate edge. The dorsal paramere branch also bears a sinuous thin sclerite directed mediad and cephalad. The sides of the pala are straight and diverge towards the wide weakly sclerotized front. The tip of the parallel trigonium is shallowly excised, the corners are blunt, in the middle of the notch a small triangle projects ventrally. The parameroids resemble those of the relatives.

Note. The males studied here were taken together with syntypes but are inadvertantly left over material without type status (personal communication C.H.S. Watts).
