Diagnosis. The next three species have the forewings rather short and deep,
the apex and distal margin tending to be scrolled ventrally somewhat. The ground
colour is bone-white, traversed by slightly greyer fasciation, and with blocks
of dark greenish brown basally and in the medial area, two patches in the
latter, slightly displaced from each other at a central break. The marginal zone
is medium grey, diffusing away basad into an area where it is interrupted by
irregular transverse bands of the ground colour. The three species are best
distinguished on genitalic characters, though the next two do appear to have
slight facies differences. The genitalia of florida resemble those of
G. quadrifera
Warren comb. n. (New Guinea, Bismarcks) and more distantly those of
G. variegata Hampson (see below) in having the row of peg-like setae along
the costal margin of the valve, but this margin is more strongly curved and the
setae are generally twice as long. The hair-setae from the expanded ventral part
of the tegumen are not thicker and darker at their base as in variegata,
and the saccular shield is broader. The saccus is broader at the base, more
triangular.
Taxonomic note. The similarity of the male genitalia to those of
quadrifera may indicate conspecificity.
Geographical range. Sundaland, Sulawesi (slide 17154), ?New Guinea,
Bismarcks (quadrifera).
Habitat preference. The only Bornean specimen known is the holotype male,
taken by A.R. Wallace in Sarawak, most probably in the lowlands.
