Table 18. Morphometrics for Brachyhypopomus pinnicaudatus. LT, lectotype; SD, standard deviation. Data for lectotype, ANSP 163463 (Cayenne, French Guiana) are from Hopkins (1991). Ranges for the type region refer to type specimens from the “Grand Pripris”, French Guiana (lectotype not included in ranges). Ranges for the other population refer to non-type specimens from the vicinity of Tefé, Amazonas, Brazil (Central Amazon basin).
