توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 10; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 9; مهره ها: 36 - 37. Distinguished from its epigean and cave congeners by the combination of the following characters: small size (max. 4.63 cm SL); pigmentation pattern intermediate between epigean and cave Ituglanis species, with small light brown spots on body, spots twice larger than in I. epikarsticus and I. ramiroi; eyes relatively developed when compared to cave species but reduced when compared to the epigean ones, with diameter varying from 0.2-0.3 mm (3.4-6.1% HL) in adults to 0.5 mm (5.7% HL) in juveniles (vs. 0.8-1.1 mm, 10.4-13.7% HL in adults of epigean Ituglanis species; n=6, 5.57-6.3 cm SL). Maxilla with prominent medial-posterior projection; fronto-lachrymal as long as maxilla, posteriorly pointed; posterior process of palatine 1/2 of palatine length, with medial concavity accentuated; vomer elongate with a small constriction in neck; opercle with 11 odontodes and interopercle with 26 odontodes; caudal skeleton with upper hypural plate triangular and lower trapezoidal, neural spine of preural centrum with rounded extremity, dorsal procurrent rays 16 and ventral 14 (Ref. 55401).
Occurs in the upper mainstream tributaries inside a cave, near the sinkhole end (Ref. 55401). A solitary species with swimming activity on the bottom, in midwater and sometimes extending to the surface (Ref. 55401).
