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).
