Nigriblephara radula Holloway 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.
