This could be the first record
of this Family in Indonesia! The next relatives live in Singapore (only one specimen from 1930), South India and northern Australia. I found this larva (L: ~1.5cm) beneath the loose but intact bark of a living tree (possibly Damar tree, Dipterocarpaceae) in the tiny patch of lowland rainforest called Dungus Iwul in the west of Java. This larva is supposed to be a non-specific ambush predator [COSTA et al
., 2006]; next to this larva there were a couple of Handsome Fungus beetles: www.flickr.com/photos/gbohne/5134864126/
The larva of the "Texas beetle" had been an entomological enigma for 25 yrs in 19th century!
