🐟 Physical Description

Dorsal soft rays (total): 11; Anal soft rays: 8; Vertebrae: 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 . : elongated.
