Bamboosiella brevis Okajima, 1995a: 307 .

Described originally from Thailand (Okajima 1995a), this species is recorded here for the first time from China. According to the collection information below, this species is widely distributed from southwestern to southern China. The feeding habit of this species is unsure. Presumably it is predacious because it could be found from different parts of bamboo, such as the dry sheaths, tender or older leaves and even the leaf litter. This species is somewhat similar to B. exastis, but can be distinguished from the latter by the key above.
