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).
