Eubryopterella
triangulata sp. n.
 17-19mm. The facies is a much more brownish grey, without the
bluish tinge of vaneeckei and cinerea.
The fasciation is more obscure on the forewing except for the very irregular,
fine, dark postmedial and antemedial fasciae within a paler medial zone; these
are close together over the dorsal half but diverge anteriorly to flank on each
side a conspicuous but diffusely bordered dark brown triangle on the costa.
There is a punctate pale submarginal on both fore- and hindwings. The male
genitalia have a more bulbous uncus than cinerea, and the saccular and costal lobes are
narrower and barely detached from the rest of the valve. The costal one is basal
to the saccular one rather than distal to it.
