Paramere shape and the spiculose glomerule-like structure at the
end of “C” shaped base of aedeagus are the most distinctive features of N. pradoi sp. nov.
Neosilba pradoi sp. nov. is morphologically closely related to N. bella Strikis & Prado, 2008 and to
N. bifida Strikis & Prado, 2005, forming another complex of cryptic species in the genus Neosilba. These species
can only be surely separated through the analysis of male genitalia.
