“Meganola”
basalactifera
sp. n.
6-9mm. The forewings are divided centrally by two closely parallel, slightly
curved black fasciae, distal to which is a whitish band and a generally pale
grey marginal zone. Basal to these fasciae the wing is extensively cream in
colour, surrounded by a medium grey zone that is broader costally. In general
appearancethe species resembles somewhat the European
“M.”
togatulalis
Hübner, but this is a larger species lacking the definite whitish band distal to
the black ones and having the paler part of the basal zone nearer the costa than
the dorsum. The Brunei specimen listed below is smaller, the grey areas of the
wings darker than in the other two. The male genitalia have the uncus robust,
tapering, with a narrower apical spine. The valves are rather narrow,
tongue-like, with a harpe that is acute distally and in a basal spur, with
smaller teeth along its dorsal margin between these two spines. The apex of the
aedeagus is densely and extensively spined. The vesica is rather sock-like, with
a short, broad cornutus on the ‘heel’. The female genitalia (Himalayan specimen)
have a very broad ostium, a funnel-like ductus with a lateral lobe, and a narrow
bursa that lacks a signum.
