Abstract:
Siju Cave in the Garo Hills of Meghalaya, India was the subject of a meticulous and detailed biological survey in 1922. The cave was re-visited, and the biota documented in 2019. Observations made in 2019 were compared to those reported from 1922 and placed in context by comparisons to observations made in other Meghalayan caves. In many respects the biota resembled that recorded in 1922 but two key differences were noted. Firstly, in 2019 the bat population and the extent of the associated guano deposits were noted to be considerably reduced relative to those described from 1922. Correspondingly, the abundance of the guano-associated biota appeared considerably reduced from that of 1922. Secondly, in 2019 a distinctly troglomorphic cockroach was found to be abundant throughout the cave. This cockroach was eyeless, totally lacking in pigmentation and had pronounced elongate antennae. It is inconceivable that it would have been overlooked in 1922, so it can only be concluded that it was not then present in the accessible areas of the cave.
