Polynesia Swinhoe
Type species: sunandava
Walker, Sri Lanka.
Synonym: Placotome
Warren (type species truncapex Swinhoe, N.E. Himalaya, Peninsular
Malaysia, Bali).
All species in this
genus have primrose-yellow wings marked with punctate red fasciae as in the
Bornean species illustrated here. The larger red patches are centred greyish.
Females tend to have the red more orange, less emphatic than the males, and
males of P. truncapex have the forewing apex shallowly excavate.
The hindwing margin has two slight angles where the stronger red marks occur.
The male antennae are filiform.
The male genitalia
have valve setae much as in Eois and related eupitheciines. At the base
of the valve costa are long, sinuous spines that may be modified labides, and
the uncus is reduced with corresponding development of the subscaphium, hence
the genus may be eupitheciine. The saccus is enlarged in the two non-Bornean
species.
The female genitalia
have an ovate bursa arising from a moderately long and slender ductus, the
distal half of which is sclerotised. The signum consists of an oval patch of
scobination, spines extending out from each side of a longitudinal pleat,
perhaps similar to that in Poecilasthena or Parasthena.
The genus consists
of the three species mentioned here. P. sunandava also occurs
disjunctly in India, Peninsular Malaysia, Sumbawa, Larat and New Guinea.
