Garudinia triangulata sp. n.  

Garudinia triangulata (holotype)
(x 1.73)

9-10mm. This species is slightly larger than the previous three, with paler, more excavate hindwings. The distal bands on the forewing are broader, the more basal ones triangular rather than semicircular and reaching the costa; the two are separated by a broader white area. The male genitalia have the distal parts of the saccular process much broader than in the previous three species and diagnostically apically bifid. The aedeagus apex is ringed with small spines and several larger ones, but the vesica is only finely scobinate over its distal half.
