ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 11; ຄີກົ້ນຂອງປາ: 8; ສັດທີ່ມີກະດູກສັນຫຼັງ: 36. Distinguished from its epigean and cave congeners by the combination of the following characters: small size (max. 3.4 cm SL); the higher degree of reduction in body pigmentation and in eye size, 2.0-2.1% HL; supraoccipital fontanel very reduced or absent; base and distal extremity of laminar surface of urohyal with similar widths, dorsal process short; posterior process of palatine as long as palatine length, medial concavity slightly rounded; maxilla with discrete medial-posterior projection; fronto-lachrymal 2/3 length of maxilla, anteriorly and posteriorly pointed; opercle with 9 odontodes and interopercle with 20-21 odontodes; 5 pairs of ribs (also observed in a juvenile of I. bambui); caudal skeleton with upper hypural plate triangular and lower one rectangular, neural spine or preural centrum with acute extremity, dorsal procurrent rays 14 and ventral 10 (Ref. 55401).
Body shape (shape guide): elongated.
Occurs in pools in a set of rimstone dams (wall-shaped barriers of calcite, aragonite or other chemical deposits that impound water pools), 10-30 cm deep and with rocky bottom (Ref. 55401). A solitary species, swimming on the bottom, along the walls and sometimes at the surface of the pools (Ref. 55401).
