Tamba
cautiperas Hampson comb. n.
Marapana
cautiperas Hampson, 1912, J. Bombay nat. Hist. Soc.,
21: 1235.
Diagnosis.
The forewings are marked in a similar manner to the much larger Tamba
magniplaga Swinhoe (p. 357). but the basal margin of the dark brown apical
zone is more oblique, and the paler patch within it is greyer and sited more
centrally on the costa; the wings are also narrower. The hindwings are a
distinctly darker grey-brown and much more obscurely marked than the forewings.
Taxonomic
note. This species was placed with the Australasian genus Olulodes
Bethune-Baker
in the BMNH curation, but was transferred with two Australian species by Poole
(1989) to the hypenine genus Lithilaria
Rosenstock.
The Australian species (conscripta Lucas and haemacta Turner)
were placed in Tamba by Nielsen et al. (1996). As cautiperas
has
features of the facies and male abdomen that are also consistent with placement
with Tamba,
it is transferred to that genus here. However, the male eighth sternite has a
pair of coremata rather than the usual hair pencils, and there is not a central
corema anterior to these.
Geographical
range. Sri Lanka,
Hainan, Singapore, Sumatra (HS / ZSM), Borneo, Sulawesi.
Habitat
preference. Six specimens have been taken in recent surveys from elevations
up to 100m, all from forest though some with disturbance: Danum Valley in Sabah;
Labi in Brunei (4); Semengok, near Kuching in Sarawak.
