Bornolis
Gen. n.
Type species: kamburonga
Holloway.
This genus is
erected for a single Bornean endemic that was originally described in the genus Hadena
Schrank because of general similarities of the forewing facies to some
members of that Palaearctic genus.
Typical Hadena have,
in the male genitalia, a coronate cucullus, a strong central, saccular harpe,
and a bifid, scobinate juxta. The female genitalia have a weak appendix bursae
if they have one at all, and the bursa has one, or sometimes two, bandlike
scobinate signa.
The Bornean taxon
lacks, like Hadena, the trifine hair pencil but also lacks the male
features listed above. The harpe is reduced to a small, rather distal ampullus
and overlaps a pickaxe-like process that arises from the costa. The form of this
is bilaterally asymmetric as is the tapering, acute, coronaless valve apex. The
juxta is simple, strap-like. The aedeagus has an elongate vesica with a basal
lateral arm and a variety of cornuti and scobinate patches as illustrated (Fig.
72). The female genitalia have a long, relatively broad, sclerotised ductus
bursae, a well developed, corrugate appendix bursae, and four scobinate bands in
the bursa.
There is some
similarity in general facies, tapering valves with a process from the costa in
the male genitalia, and the lateral lobe to the aedeagus vesica to the
Palaearctic Panolis Hubner (type species flammea Denis &
Schiffermuller) but in that genus there is no asymmetry in the male genitalia,
and a much weaker ductus and appendix bursae in the female.; the bursa contains
only two scobinate bands.
Support for an
association with Panolis would be provided if the larvae were found to
feed on some of the many conifers present at the altitude at which the adult
occurs. P. flammea is a conifer feeder.
