Papuarisme Gen. n.
Type species: murudensis
Prout
This genus is
erected for a major grouping of species currently placed in Horisme Hübner
but with morphological features that are far removed from that genus (see also
comments by Holloway (1979: 312) on Australian taxa with facies somewhat similar
to that of Papuarisme, and on Papuarisme itself (Holloway, 1986b:
550-1)).
The general
colouration is grey to black, sometimes tinged with pale green or yellow, rather
than brown as in typical Horisme. The hindwings are only lightly
fasciated, if at all, whereas they are fasciated as strongly as the forewings in
Horisme. The forewing antemedials and postmedials are strong, with a more
or less symmetrical arrangement across the medial area, the antemedial sequence
of fasciae being reversed in the postmedial sequence. The postmedial sequence is
angled obtusely more or less centrally. The male antennae are filiform.
The male abdomen
lacks coremata though the eighth segment is slightly modified with undulating
margins and a rib of sclerotisation, and the apodemes of the second tergite are
enlarged, broader apically like the ears of a cartoon rabbit (Fig 595)! The
genitalia are diagnostic, with the valves distally circular, fringed with a mass
of fine hair scales, but with a straighter sclerotised costa that bears a
central spur in Bornean species but not in those from New Guinea examined. The
saccus is broad, quadrate, often centrally notched. The uncus is narrow,
needle-like. The anellar structures are complex, the juxta broad, rather
tonguelike, coarsely scobinate distally. The aedeagus vesica lacks cornuti in
Bornean species, but they are present in some New Guinea species.
The female genitalia
have a rather swollen ductus bursae in Bornean species but not notata Rothschild
from New Guinea. The bursa itself is pyriform, with a large, ovate, plate-like
signum bearing numerous transverse ridges of scobination (transverse in notata).
The ovipositor lobes are small, rather globose.
Apart from the
Bornean species discussed below, the genus has a few species in Sulawesi and the
Moluccas and a large group in New Guinea as follows: P. aeolotis Prout
comb. n.; P. albimedia Warren comb. n.; P. albicristata Warren
comb. n.; P. brunneata Warren comb. n.; P. contaminata Warren
comb. n.; P. disrupta Warren comb. n.; P. genuflexa Prout
comb. n.; P. griseata Warren comb. n.; P. illustris Prout
comb. n.;
P. leucotmeta Prout comb. n.; P. lichenosa Warren
comb.
n.; P. notata Rothschild comb. n.; P. rufilunata Warren
comb. n.; P. symmetrozona Prout comb. n. All are
montane.
