. The new species inhabits subterranean streams. During the time of collection, the rainy season had started and the water in the stream was murky and fast flowing, making observation difficult. Crabs were nevertheless observed to intermittently appear near the water edge, waving their chelae and legs as if foraging for food. It is unclear whether this behavior is normal or induced by the presence of the survey team (e.g., vibrations from the team’s footsteps, water disturbance and lights). Crabs were abundant at the locality and were all found in water, indicating it is primarily an aquatic species. The subterranean stream at the

Though snails could not be observed in the subterranean stream due to the murky water, they were found clinging on the flowstone at the drop off. Further research using methods such as gut content analysis would be needed to further confirm this.
