Kurt,
I have seen a picture of Cyclophorus perdix (Java) aestivating on the
lower portion of a tree trunk.  Though most cyclophorid's I've
encountered in the field (Caribbean - Indonesia) have been in leaf
litter and limestone scree, I do assume the larger cyclophorids do
find their way onto trees.  The data I have for Cyclophorus rafflesi
eximeus (50mm+) from Sumatra also indicates "living on tree
trunks".  The habitat of choice may be seasonal or moisture
dependent.  I concur that Leptopoma are arboreal, having found all
crawling on broad-leaf foliage.
