violacea sp. n.
, 10mm. The size and forewing shape are as in exhibens,
but the colour of the forewing is a more uniform violet grey. There is a black
dot just basal to a weakly paler reniform, and distal to this is a fine fawn
postmedial, tinged yellowish basad, that extends obliquely distad from the
dorsum to half way to the costa, then angles obtusely twice to circumnavigate
the reniform and meet the costa obliquely just anterior to it. There is a row of
black submarginal flecks in some specimens and a very irregular antemedial
fascia. The male abdomen has the eighth segment as in the type species. In the
genitalia, the uncus is longer, and the tegumen and vinculum are of
approximately equal length. The valves are narrower but the basal ornamentation
is more complex and robust, the distal process of the sacculus being longer,
curved and having a prominent spine near its base on the interior margin of the
sacculus. There is a weak juxta of the inverted ‘Y’ type.
