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.
