Actinopterygii (ray-finned fishes) > Siluriformes (Catfish) > Trichomycteridae (Pencil or parasitic catfishes) > Trichomycterinae
Etymology: Ituglanis: Greek, itys, ityos = circle + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335);  agreste: The name agreste is from the Latin agrestis, meaning relative to land, field, wild, or rustic. This refers to eastern Brazil, encompassing the area between the Rio Grande do Norte State to the middle section of rio de Contas basin in Bahia State, that marks the transition between two distinct biomes, the Atlantic Forest and the semi-arid Caatinga, where the new species was discovered. A noun in apposition.

Environment / Climate / Range Ecology

Freshwater; demersal; depth range 0 - 2 m (Ref. 94155).   Tropical

Short description Morphology | Morphometrics

Dorsal soft rays (total): 11-12; Anal soft rays: 10 - 11; Vertebrae: 36. This species is diagnosed from all congeners, except Ituglanis paraguassuensis, by the following characters: 36 vertebrae (vs. 38 or more in all other Ituglanis, except in I. paraguassuensis, I. nebulosus, I. bambui, I. epikarsticus, I. ramiroi, and I. passensis; unknown for I. guayaberensis); 5-6 ribs (vs. 2 or 3 in I. amazonicus, I. eichorniarum, I. gracilior, I. ina, I. macunaima, I. nebulosus, and I. parkoi ; 4 in I. laticeps and I. cahyensis; 7 in I. passensis); i,6 pectoral-fin rays (vs. i,4 in I. cahyensis, I. macunaima, and I. parahybae ; i,5 in I. amazonicus, I. eichorniarum, I. metae, and I. nebulosus; i,7 in I. bambui, I. epikarsticus, I. mambai, I. passensis; iii,5 in I. guayaberensis; i,8 in I. ramiroi); and irregular brown blotches covering the skin (vs. distinct color pattern in all other Ituglanis; absence in I. ina and the subterranean species, I. bambui, I. passensis, I. epikarsticus, and I. ramiroi). Ituglanis agreste is also easily distinguished from the subterranean species by its large eyes (vs. minute eyes) and intense pigmentation (vs. pigmentation absent or almost lack); and from its geographically closest species I. paraguassuensis by having 26-30 odontodes in an elongate interopercle patch (vs. reduced with 14-15 odontodes); seven branchiostegal rays (vs. 8) and pore s1 lacking (vs. s1 present) (Ref. 94155).

Biology     Glossary (e.g. epibenthic)

Occurs in a mid-small size river with width up to 8 m, in a moderate slope with clear and cold water, with transparency of about 2 m. The river is characterized by mainly turbulent water flow , with alternating areas of currents and pools, though a predominance of moderate to strong drifts. The substrate is composed of rocks and sand. Collected together with Astyanax bimaculatus (Linnaeus), Callichthys callichthys (Linnaeus), Geophagus brasiliensis (Quoy & Gaimard), Rhamdia quelen (Quoy & Gaimard) and Poecilia reticulata Peters (Ref. 94155).
