Nola
helpsi
sp. n.
8mm. In facies and the fasciculate male antennae this species is similar to
mesosticta but is greyer, the male darker than the female. There are dark
patches of raised scales subcostally in the medial area in similar positions,
but the postmedial is more sinuous, less angular in its course, which is more
precisely parallel to the margin. In the male abdomen the apodemes of the eighth
segment are long, slender and widely separated on both tergite and sternite (the
tergal ones partially fused centrally in
mesosticta).
The valve arms are much more slender in helpsi, particularly the ventral
ones, and there is no setose lobe at the base of the dorsal ones. The aedeagus
is relatively much shorter.
