Diagnosis. Indohya gollum has 16 carapaceal setae and lacks eyes, thus resembling I. currani , I. napierensis and I. typhlops . It differs from I. currani and I. typhlops in its larger size [e.g. chela (with pedicel) 1.90–2.01 (Ô), 1.86 (♀), vs. 0.77–0.855 (♀) in I. currani and I. typhlops ]. It differs from I. napierensis as follows: prolateral margin of chelal hand smooth (finely granulate in I. napierensis ); chelal hand (without pedicel) 1.79–1.96 (Ô), 1.84 (♀) × longer than broad [1.71 (♀) in I. napierensis ]; setae on pedipalpal femur of moderate length, not as long as width of femur (about as long as width of femur in I. napierensis ); and cheliceral hand with 6 setae (7 setae in I. napierensis ).

Description (adult). See Harvey and Volschenk (2007).

Description (tritonymph). See Harvey and Volschenk (2007).

Description (deutonymph). See Harvey and Volschenk (2007).

Description (protonymph). See Harvey and Volschenk (2007).

Distribution and remarks. Indohya gollum has been recorded from two caves (Nefertiti’s Palace and Cave KNI-19) situated in the Devonian limestone karst system of the eastern Kimberley region of Western Australia ( Fig. 6B ). The caves are located within the Victoria Bonaparte bioregion.

Conservation assessment. Indohya gollum has been found within two closely located caves in the eastern Kimberley. The species does not appear to meet the status of threatened using the criteria developed by the International Union for Conservation of Nature (2012).
