stomata sp. n.
7-8mm. The forewings are
less heavily marked than in subaurana, the subcostal arcuate grey line
being narrow, broken centrally, its basal part forming the upper arc of a series
of three lines that depict what look like closed leaf stomata, one at the base
of each forewing. The dorsal line is also arcuate, the central one straight,
slightly closer to the dorsal one but not touching either; in subaurana it
is closer to the dorsal one and fuses with it distally to form a loop. The
enclosing arcuate marks join each other at their basal ends. The male genitalia
in subaurana have the valves evenly curved and tapering to an acute apex,
whereas in stomata the curvature is mainly subapical, the valve only
tapers significantly beyond that point, and there is a small spur on the ventral
margin where the curvature is most intense. The aedeagus is longer.

Habitat preference. More
frequent than its congener, stomata is found in similar habitats over the
same altitude range, but shows more preference for heath forest (kerangas).
