Description: Specimens of G. carapo   from Suriname overlap substantially in morphometric and meristic PCspace with specimens from other localities ( Figures 4 View FIGURE 4 , 5 View FIGURE 5 , and 12). Gymnotus carapo carapo   is characterized by the following combination of statistically significant (p <0.01) traits when compared to the rest of the species as a whole (see Principal Components Analyses and t-tests): long preorbital distance (PR 31.4%–40.2% HL, mean 36.3% vs. 28.0%–39.4%, mean 34.6% in all other subspecies) and wide mouth (MW 33.6%–47.6% HL, mean 43.0% vs. 32.2%–49.0%, mean 40.2% in all other subspecies).

Distribution: Known from Atlantic coastal drainages of Suriname and French Guiana, including the Brokopondo, Nickerie, and Suriname districts of Suriname in the Lucie, Suriname, and Corantijn rivers, and all departments of French Guiana ( Figure 2 View FIGURE 2 B).

Etymology: Subspecific epithet derived from the specific epithet.
