GYMNOTIFORMES

Gymnotidae . Primary.

Gymnotus cylindricus La Monte, 1935 . Knifefish, pez cuchillo. Native.

Departments: Atlántida, Choluteca, Colón, Comayagua, Cortés, Gracias a Dios, Santa Bárbara and Yoro. Drainages: Atlantic slope: Motagua, Chamelecón, Ulúa, Leán, Cangrejal, Lislis, Aguán, Sico-Tinto, Plátano, Patuca, Warunta and Coco. Pacific slope: Choluteca.

Remarks: Albert & Miller et al. (1995) stated that G. cylindricus occurs only in drainages on the Atlantic slope of Central America. However, some of the material they examined in their paper came from localities in the Honduran Pacific slope, wrongly identified as Atlantic slope localities. This material includes: UMMZ 155831, UMMZ 188296, UMMZ 188297 (see Albert & Miller, 1995; Albert et al., 1999; Albert, 2001). Further, Bussing (2002) reported G. cylindricus from the Yeguare River, a tributary of the Choluteca River, which drains to the Gulf of Fonseca on the Honduran Pacific slope.

Gymnotus maculosus Albert & Miller, 1995 . Spotted knifefish, cuchillo manchado. Native. Departments: Choluteca and Valle. Drainages: Pacific slope: Lempa, Goascorán, Nacaome, Choluteca, and Negro.

Remarks: Albert & Miller (1995) did not include material from Honduras in the description of the species. However, Bussing (2002) and Miller et al. (2005) report a continuous distribution extending from southern México to Costa Rica, including the Honduran Pacific slope.
