Known only from the type locality: An unnamed cave in Mount Gunung Kajang (alt. 900m), Pulau Tioman, Malaysia (2°50'N, 104°10'E).


The cave in which the animals were collected is reported to be developed in granite. Up to twelve specimens were seen in pools 4 inches deep with a substrate of rock and sand and with a gentle flow of water. Air temperature was 15oC but the water was cold to the touch (suggesting a long underground flow?). Tadpoles and crabs were also found in the water. Other caves and surface streams in the area were investigated but no other fishes were seen. Some details of Pulau Tioman are provided by Jasmi (1999), Ng, Yong and Sodhi (1999) and Ng, Tan and Lim (1999).


Unpublished molecular data (of V. Slechtova and J. Bohlen) shows that Speonectes tiomanensis belongs to a lineage very distinct from Oreonectes, Lefua and Sundoreonectes (Kottelat 2012:139). This is no surprise for a freshwater, high altitude species limited to a small off-shore island.
