Neosilba amphora Galeano-Olaya & Canal

Neosilba amphora sp. nov.

Diagnosis: The scutellum of the N. amphora has two anterior setulae to basal bristle, spherical-shaped male terminalia, aedeagus with the filament bottlelike shaped distally spiculated and with spine-like apical process in ventral view, paramere rectangular-shaped, surstylus with 10 prensisetae at each side. The general shape of the male terminalia (spherical, prominent cerci and short filament) of N. amphora is similar to those of the major group and N. parva. N. amphora differs from species in the major group because the filament of the aedeagus in this group of species is approximately the same width in all its extension, and reaching beyond the base of cerci N. parva it is the most similar species to N. amphora, in fact both species belong to the parva group which could be characterized by hemispherical male terminalia with short filament of the aedeagus (not reaching the base of cerci) and with different widths in its extension. N. parva has a chalice-shaped filament (i.e., wider at the apex that at the base) and 5 to 6 prensisetae at each side.
