Lyssomanes antillanus
Peckham, Peckham & Wheeler, 1889
,
L. portoricensis
Petrunkevitch, 1933
,
L. unicolor
(Taczanowski, 1872)
and
L. michae
Brignoli, 1984
(see Galiano, 1962: pl. III, figs. 8–9 and pl. VI, figs. 1–3; Galiano, 1980: pl. III, figs. 23–24; Brignoli, 1984: figs. 4, 7), but can be easily distinguished from them by the elongated and almost touching embolus and median apophysis (clearly separated in the above species), as well as by the ribbon-shaped conductor (fan-shaped in the above species) (see
Figs. 1–4
).
