Paectes
leucotrigona Hampson
Ingura leucotrigona Hampson,
1905, Ann. Mag. nat. Hist. (7), 16: 371.
Diagnosis. The striking banding of rufous cream on dark grey of the forewings
distinguishes this species. This pattern is approached by P. osseotrigona, described
and distinguished below.
Taxonomic notes. The male and female genitalia of this, the next two species and P.
fabrica Swinhoe, a species with grey forewings from Peninsular Malaysia and
Sumatra, are indistinguishable. The somewhat different geographical ranges
suggest these are distinct species rather than variants of a single species, but
this needs to be confirmed by the collection of further material and rearing
from identified females. Coincidence of singletons of all three species in one
sample (900m on G. Api) during the Mulu survey perhaps points more to the
variant hypothesis.
This complex has affinities with P. variegata Roepke from
Sulawesi and another closely related group of species that has evolved in New
Guinea (pratti Bethune-Baker, costistrigata Bethune-Baker and
three undescribed species).
Geographical range. Peninsular Malaysia, Sumatra, Borneo.
Habitat preference. Apart from the singleton from lower montane forest on
G. Api mentioned above, the species has been taken in ones and twos at three
lowland rainforest localities in Brunei (Labi, Rampayoh, Ulu Belait).
