T. kuchingensis is known from only three areas (Bako National Park, the Bau area and around Kuching). Its total range area is around 100 km², and although part of its range falls within a national park its habitat is declining as peat soil areas are converted to agricultural land. Its limited range and ongoing habitat declines qualify the species for Endangered.
|Range Description:||Malaysia: East Malaysia: Sarawak: This species is known only from the vicinity of Kuching and possibly is also found in Bako National Park. More material (15 specimens) was collected in 2002 from Gunung Tai Ton, Gunung Tongga (one specimen) and Gunung Aup (one specimen) in the Bau Limestone Area of Sarawak. So the number of localities known is now three (all in the Bau Limestone Area). |
The extent of occurrence (EOO) is estimated at 100 km², based on two original collections made a few years apart by different collectors (both list locality as simply “Kuching, Sarawak”), plus new material belonging to this species collected in 1986 from Bako National Park about 35 km north of Kuching city. However, the new specimen was not directly examined – it is identified from a photograph, so the original locality is the only one for certain – but the authors speculate that “Kuching” as a locality might well have referred to the Bako National Park north of the city where the new specimens was photographed. So the EOO estimate of 100 km² might be acceptable.

|Population:||There is no information on population size, abundance, or trends.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||These crabs are semi-terrestrial, foraging on vegetation at night, but digging and hiding in deep burrows in peat soil by day. This species digs deep holes in the forest floor on forest soil many meters away from the nearest stream. Collected from burrows in a small cocoa plantation next to the main forest.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
The peat swamp remnants this crab occurs in are all small and their long-term survival questionable. Only one of the peat swamp remnants (one of the smallest ones) is protected as a state park (not a national park) and nests in an urban area, while the rest are still been developed for a wide range of agricultural crops.
|Conservation Actions:||The retention of Bako area as a National Park would help to protect this species.|
