Abstract

An inhabitant of tropical America, the Central American halfbeak (Hyporhamphus roberti hildebrandi), is one of 2 subspecies of halfbeaks of the subgenus Hyporhamphus (Collette 2003, Collette 2004) that belong to the family Hemiramphidae. This family has representatives from the Atlantic, Pacific, and Indian Oceans (Greenfield and Thomerson 1997, Berra 2001, Collette 2004), and nearly all species are marine; however, some Hemiramphidae species in the Indo-Australian region are restricted to freshwater (Greenfield and Thomerson 1997).

The distributional range of H. r. hildebrandi extends along the Caribbean coast of Central America from Mexico to the Gulf of Uraba in Colombia (Collette 2004, Miller et al. 2005). The sub-species is considered marine and estuarine, commonly found in mangrove forests (Greenfield and Thomerson 1997), and coastal lagoons (Schmitter-Soto 1998, Díaz-Ruiz et al. 2003, Collette 2004). For example, they have been collected in the Laguna de Bacalar in southern Mexico (Schmitter-Soto 1998) and the Tortuguero National Park in Costa Rica (Winemiller and Leslie 1992).

Previous specimens collected in Honduras have been from estuarine and marine systems or from freshwater systems with a direct connection to brackish or marine water (see NeoDat, http://www.neodat.org). Here, we report the first record of H. r. hildebrandi in Honduran freshwater (see Reis et at. 2003) as well as in a landlocked freshwater body of water.
