Symploce cavernicola
Sarawak, Borneo.—Swarming on walls of caves and in soft bird guano on the cave floor (Moulton, 1912). Hanitsch (1931) noted that this species was first recorded by Shelford from a cave in Sarawak and that there is a series from a cave in the Oxford University Museum, taken by Banks in 1928.
Malaya.—On the walls of the inner cavern of a cave at Biserat; the insects covered the walls in places (Chopard, 1919).
Sumatra.—From Baso cavern, on the west coast (Hebard, 1929).
Symploce curta
South Celebes.—Hanitsch (1932).
Symploce remyi
Tonkin.—This seems to be a true cavernicolous species (Chopard, 1929a; Colani, 1952).
