Diagnosis. This and the next species lack discal spots on the hindwing underside
except occasionally in forms with strong black apical markings to the forewing.
This species is variable but tends to be more uniform pinkish fawn; paroobathra
is pinker with rich rufous mottling and striation that is stronger over the
basal half of the wing and at the forewing apex. In forms with strong black
markings at the forewing apex, the discal spots are also strong, black in delospila,
but are weaker with orange centres in paroobathra, as is the apical
mark itself. P. delostigma has a form with pale orange patches
postmedially (illustrated), usually associated with stronger medial fasciae. The
genitalia of both species are similar but delostigma has a narrow
aedeagus vesica lacking a cornutus; there is a small, thorn like cornutus in paroobathra.
In the female of paroobathra, the ductus is narrower with a stronger
sclerotised band, and the signum is larger and set apically rather than
subapically.
Geographical range. Borneo, Sumatra, Java.
Habitat preference. This is the commonest Bornean species, found in most
lowland and lower montane forests and more rarely up to about 2000m.
