FIGURE 4 in A new species of Ituglanis Costa & Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil
FIGURE 4. Lateral view of right suspensorium (lower jaw removed) and opercular series. A) Ituglanis amphipotamus, paratype, MZUSP 65750, 49.2 mm SL, showing the posterior margin of interopercular patch of odontodes in a vertical through the middle of the opercle, not reaching the opercular patch of odontodes. B) Ituglanis proops MZUSP 60255, 57.1 mm mm SL, showing the posterior margin of interopercular patch of odontodes in a vertical through the middle of opercular patch of odontodes. HY, hyomandibula; IO, interopercle; MT, metapterygoid; OP, opercle; PO, preopercle; QU, quadrate. Scale bars = 2mm.
FIGURE 2 in A new species of Ituglanis Costa & Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil
FIGURE 2. Dorsal view of head. A) Ituglanis amphipotamus, paratype, MZUSP 65753, 66.9 mm SL. Nasal canal of supraorbital line (pores s1 and s2) and antorbital portion of infraorbital line (pores i1 and i3) absent; B) I. proops, MZUSP 79576, 55.1 mm SL. Nasal canal of supraorbital line (pores s1 and s2, black arrows) and antorbital portion of infraorbital line (pores i1 and i3, white arrows) present. Scale bars = 2mm.
FIGURE 1. Ituglanis amphipotamus, MZUSP 69393 in A new species of Ituglanis Costa & Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil
FIGURE 1. Ituglanis amphipotamus, MZUSP 69393, holotype, 70.3 mm SL; Brazil: São Paulo: Sete Barras, Rio Ipiranga, tributary of Rio Juquiá, Fazenda Brasban, Ribeira de Iguape drainage. Left lateral, dorsal and ventral views. Scale bars = 10 mm.
FIGURE 5 in A new species of Ituglanis Costa & Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil
FIGURE 5. Geographic distribution of Ituglanis amphipotamus at Rio Ribeira de Iguape and upper Rio Tietê drainages. Star represents the type-locality, Brazil: São Paulo: Sete Barras, Rio Ipiranga, tributary of Rio Juquiá, Fazenda Brasban, Ribeira de Iguape drainage. One circle may represent more than one locality.
FIGURE 3 in A new species of Ituglanis Costa & Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil
FIGURE 3. Left lateral view of head illustrating differences in the opercular and interopercular patches of odontodes. A) Ituglanis amphipotamus, paratype, MZUSP 65753, 66.9 mm SL. The posterior margin of the interopercular patch reaches the base of the opercular patch of odontodes, and the distance between the posterior margin of the interopercular patch of odontodes and the pectoral-fin base is similar to the size of the opercular patch of odontodes. B) I. proops, MZUSP 79576, 58.9 mm SL. The posterior margin of the interopercular patch reaches half length of the opercular patch of odontodes, and the distance between the posterior margin of the interopercular patch of odontodes and the pectoral-fin base, is about one third the size of the opercular patch of odontodes. IPO, interopercular patch of odontodes; OPO, opercular patch of odontodes. Scale bars = 5mm.

FIGURE 1. Ituglanis paraguassuensis, holotype, 41.2 mm SL, LIRP 5780.
Fig. 3 in Ituglanis macunaima, a new catfish from the rio Araguaia basin, Brazil (Siluriformes: Trichomycteridae)
Fig. 3. Mandible of Ituglanis macunaima, paratype, MZUSP 86251 (25.5 mm SL), medial view of right side. Abbreviations: AAR, anguloarticular; cpr, coronoid process; DEN, dentary; MKC, Meckel's cartilage.
FIGURE 6 in A new species of Ituglanis Costa & Bockmann, 1993 (Siluriformes: Trichomycteridae) from Rio Ribeira de Iguape and upper Rio Tietê basins, southeastern Brazil
FIGURE 6. Collecting localities of Ituglanis amphipotamus: A) Type locality of Ituglanis amphipotamus, Rio Ipiranga, tributary of Rio Juquiá, Ribeira de Iguape drainage; B) Ribeirão Itaquaxiara, tributary of Rio Embu-Mirim, upper Tietê drainage, upstream stretch polluted by irregular human settlements; C) Same river, downstream stretch highly impacted by the constructions of the Governador Mário Covas beltway.
