FIGURE 10 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 10 | Heptapterus longicauda, NUP 18882, 74.3 mm SL, 23°40'42"S 53°15'47"W, córrego Piava, tributary to the rio das Antas, tributary to the rio Ivaí, upper rio Paraná basin, municipality of Umuarama, State of Paraná, Brazil.
FIGURE 3 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 3 | 'Chasmocranus' brachynema, EEBP 629, 74.9 mm SL, rio Mogi-Guaçu about 1 km downstream from Cachoeira de Emas. Schubart (1964) reported this specimen after the original description.
FIGURE 7 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 7 | Localities where 'Chasmocranus' brachynema has been collected. A. Type-locality in the rio Mogi-Guaçu at Cachoeira de Emas. In the dry season, the water level lowers considerably, exposing the rocky bottoms. B. In the puddles thus formed, occasional fish specimens get trapped, such as this putative 'C.' brachynema (the identification is tentative since the specimen was not preserved). Photographs by Wellington A. M. Peres. C. Córrego Piava. Photograph by Weferson J. Graça.
FIGURE 9 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 9 | Heptapterus sp. 1. A. DZSJRP 7973, 45.4 mm SL. B. DZSJRP 7973, 108.4 mm SL. C. DZSJRP 20527, 109.2 mm SL. D. LBP 6414, 133.1 mm SL (photograph by Gabriel Silva). E. DZSJRP 20532, 152.6 mm SL. Notice the allometry in body depth, adipose-fin length, and caudal-fin length – smaller specimens present higher body depth and shorter adipose- and caudal-fin length. A and B were identified as 'Chasmocranus' brachynema by Thereza, Langeani (2019); C and E were identified as 'I.' borodini by Thereza, Langeani (2019); and D was identified as 'C.' brachynema by Pereira et al. (2013).
FIGURE 8 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 8 | Scatter plot charts of several morphometric characters as percentages of the standard length in 'Chasmocranus' brachynema (pink), Heptapterus longicauda (yellow), and Heptapterus sp. 1 (green). Depth at adipose-fin origin, cleithral width, lateral head length to opercle, adipose-fin base length, and pre-adipose length proportions are useful to distinguish between the three species, and dorsal caudal-fin lobe length to distinguish 'C.' brachynema and Heptapterus sp. 1 from H. longicauda. Data from the holotype of H. longicauda taken from Borodin (1927).
FIGURE 6 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 6 | Partial map of South America, showing the distribution of 'Chasmocranus' brachynema in the upper rio Paraná basin. Star, typelocality; losangle, NUP 22699; circle, MZUSP 22511 (rocky river channel submerged in 1974).
FIGURE 2 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 2 | 'Chasmocranus' brachynema, NUP 22699, 93.0 mm SL, 23°40'42"S 53°15'47"W, córrego Piava, tributary to the rio das Antas, tributary to the rio Ivaí, upper rio Paraná basin at the municipality of Umuarama, State of Paraná, Brazil.
FIGURE 5 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 5 | Cephalic laterosensory pores in 'Chasmocranus' brachynema, NUP 22699, 93.0 mm SL. Welldeveloped pores are outlined in black, except when hidden by other structures (in which case they are outlined in red). Poorly developed pores are outlined in grey. Abbreviations: i1–6, infraorbital sensory pores 1 to 6; ll1–2, lateral-line sensory pores 1 and 2; pm1–11, preoperculomandibular sensory pores 1 to 11; po1–3, postotic sensory pores 1–3; s1–8, supra-orbital sensory pores 1–8.
FIGURE 4 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 4 | Shape of the premaxillary tooth plates. A. 'Chasmocranus' brachynema, NUP 22699, 93.0 mm SL. B. Heptapterus longicauda, NUP 18882, 85.9 mm SL.
FIGURE 1 in Redescription of 'Chasmocranus' brachynema (Heptapteridae: Heptapterini)
FIGURE 1 | 'Chasmocranus' brachynema, EEBP 617, holotype, 128.3 mm SL, rio Mogi-Guaçu at Cachoeira de Emas, upper rio Paraná basin at Pirassununga, State of São Paulo. A. Recent photograph showing the current state of preservation of the specimen. B. Drawings from the original description, evidencing the original coloration of the specimen and the shape of the premaxillary (top) and dentary tooth plates.
