5-6mm. This is a small, pale grey species with forewing markings and male
genitalia that indicate a relationship with
Hampson (S. India, Sri Lanka) and N.
Holloway (New Caledonia). The forewing has darker grey markings and pale tufts
of raised scales. The fasciae are rather stepped, irregular in both cretacea
and calcicola compared with bitransversata where they are more
clearly defined, especially the antemedial, and oblique. The male genitalia of
all three species have the valves only partially cleft, narrow basally,
expanding to a broadly bilobed apex beyond the cleft. The harpe coincides with
the cleft and is distally directed, large in cretacea, small, slender,
directed more dorsally in calcicola, and smaller again, at right-angles
to the axis of the ventral arm in bitransversata. In all three the
aedeagus has a slender, curved spine at the apex, and the apodemes of the eighth
segment are relatively weak, separated, almost vestigial on the sternite.
