The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Amphilophus citrinellus x Cichlasoma urophthalmus

Common name: Midas x Mayan cichlid hybrid

Native Range: None. Parental species have non-overlapping ranges, and thus would not hybridize in nature. Native ranges for putative parental species are:

Amphilophus citrinellus – Pacific slope drainages in Central America from Great Lakes and crater lakes of Nicaragua to Río Coto in southeastern Costa Rica (Bussing 1987).

Cichlasoma urophthalmus – Atlantic slope drainages in Central America from Río Coatzacoalcos basin in Mexico southward into Nicaragua, including Isla Mujeres and Yucatán Peninsula (Conkel 1993; Greenfield and Thomerson 1997).

Nonindigenous Occurrences: Shafland et al. (2008) reported the collection of a suspected Amphilophus citrinellus x Cichlasoma urophthalmus hybrid by an angler in the L-30 Canal, Palm Beach County, Florida, in 2005. This fish had coloration and markings intermediate between the two putative parental species.

Means of Introduction: Likely the result of a chance spawning event between resident introduced Mayan and Midas cichlids in the canal systems in Palm Beach County (Shafland et al. 2008).

Status: Failed: no more hybrid individuals have been reported (Shafland et al. 2008).
