Nigriblephara radula sp. n.
10-11mm. This species is externally very similar to N. semiparata except
the hindwing medial zone is more obscured with dark shading. In the male
genitalia the tegumen is straight between the ‘shoulders’ rather than
trilobed. The costa of the valve has a central complex of setose lobes, the
saccular process is straight rather than curved, spoon-like, and the juxta is
slender, elongate, tongue-like, apically coarsely scobinate.
