Vouchers: Not available. Distribution: Central America; from southern Nicaragua to central Costa Rica, Atlantic and Pacific drainages; ( Nicaragua) Ni (Pacific); 5–211 masl; Sec, Dia, Amp. Occurrence and conservation status: Nat; DD (2020), population trend unknown. Literature: Bussing (1998: 198; brief description, including illustrations and an identification key, and information on distribution, with a map, and ecology) and Angulo (2021: 54; listed, including information on distribution). Remarks: This species was listed as endemic to Costa Rica by Angulo (2021); however, the same author ( Angulo 2021: 54) reported the following distribution: “Middle America; from (probably) southern Nicaragua to central Costa Rica, Atlantic and Pacific drainages”. Unpublished data and personal communications by local fishers (Francisco Samaniego, December 14, 2019 and Nestor López, April 2, 2020) and colleagues (Topiltzin Contreras, February 5, 2020) support the occurrence of B. olomina in the southern Pacific of Nicaragua, near the border with Costa Rica, as proposed by Bussing (1998), Lyons et al. (2020) and Angulo (2021).
