Diagnosis.
This and the next species have narrower forewings than noctilio with
the reniform mostly dark, though with a paler spot posteriorly within it. The
markings of nyarlathotepi and the related procellosa
Butler are more variegated, less uniform
than in uniformis Holloway. The submarginal zone of the forewing in uniformis
is
distinguished by a series of oblique, approximately parallel, paler lines. On
the underside, uniformis
has
the hindwing more strongly suffused violet, with the fasciation more prominent;
on the forewing the female of uniformis has a cream area basal to the postmedial.
Taxonomic
note. This species is very similar to procellosa
(Japan,
Oriental tropics to Sumatra, Java and Lombok) but differs in two features: the
dorsal loop to the forewing postmedial is bulbous and often highlighted with
paler colour; the small spined diverticulum most distant from the long one in
the aedeagus vesica is reflexed and bears a small lateral lobe. The material
from New Guinea referred to and illustrated as procellosa by
Holloway (1979) represents a new species, azatothi Zilli
& Hogenes (in prep.).
Geographical
range. Borneo.
Habitat
preference. This is the most frequent of the three species and ranges from
the lowlands to 2600m. It is perhaps slightly commoner in montane habitats
between 1000m and 2000m.
Biology.
Mutuura
et
al.
(1965) illustrated the larva of the closely related procellosa
(as
alope)
in Japan. It is long, slender, tapering at the head and rear, leaf-green, with a
prominent pair of dull yellow tubercles on A8 and with a general scattering of
small white dots; there is one large white dot subdorsally on A8. Miyata (1983)
noted Caesalpinia
(Leguminosae)
as a host plant, but Sugi (1987) stated that the larva fed on Gleditsia
in
the same family.
